Yeachan-Heo 6eb396720e Make Claude project bootstrap available from a real init command 
The Rust CLI previously hid init behind the REPL slash-command surface and only
created a starter CLAUDE.md. This change adds a direct `init` subcommand and
moves bootstrap behavior into a shared helper so `/init` and `init` create the
same project scaffolding: `.claude/`, `.claude.json`, starter `CLAUDE.md`, and
local-only `.gitignore` entries. The generated guidance now adapts to a small,
explicit set of repository markers so new projects get language/framework-aware
starting instructions without overwriting existing files.

Constraint: Runtime config precedence already treats `.claude.json`, `.claude/settings.json`, and `.claude/settings.local.json` as separate scopes
Constraint: `.claude/sessions/` is used for local session persistence and should not be committed by default
Rejected: Keep init as REPL-only `/init` behavior | would not satisfy the requested direct init command and keeps bootstrap discoverability low
Rejected: Ignore all of `.claude/` | would hide shared project config that the runtime can intentionally load
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep direct `init` and `/init` on the same helper path and keep detection heuristics bounded to explicit repository markers
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: interactive manual run of `rusty-claude-cli init` against a non-test repository

Yeachan-Heo 0376604dea Expose structured thinking without polluting normal assistant output 
Extended thinking needed to travel end-to-end through the API,
runtime, and CLI so the client can request a thinking budget,
preserve streamed reasoning blocks, and present them in a
collapsed text-first form. The implementation keeps thinking
strictly opt-in, adds a session-local toggle, and reuses the
existing flag/slash-command/reporting surfaces instead of
introducing a new UI layer.

Constraint: Existing non-thinking text/tool flows had to remain backward compatible by default
Constraint: Terminal UX needed a lightweight collapsed representation rather than an interactive TUI widget
Rejected: Heuristic CLI-only parsing of reasoning text | brittle against structured stream payloads
Rejected: Expanded raw thinking output by default | too noisy for normal assistant responses
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep thinking blocks structurally separate from answer text unless the upstream API contract changes
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test -q
Not-tested: Live upstream thinking payloads against the production API contract

Yeachan-Heo 0d256f7dcc Improve streaming feedback for CLI responses 
The active Rust CLI path now keeps users informed during streaming with a waiting spinner,
inline tool call summaries, response token usage, semantic color cues, and an opt-out
 switch. The work stays inside the active  + renderer path and updates
stale runtime tests that referenced removed permission enums.

Constraint: Must keep changes in the active CLI path rather than refactoring unused app shell
Constraint: Must pass cargo fmt, clippy, and full cargo test without adding dependencies
Rejected: Route the work through  | inactive path would expand risk and scope
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep future streaming UX changes wired through renderer color settings so  remains end-to-end
Tested: cargo fmt --all; cargo clippy --all-targets --all-features -- -D warnings; cargo test
Not-tested: Interactive manual terminal run against live Anthropic streaming output

Yeachan-Heo 40c70b99f4 Preserve verified session persistence while syncing remote runtime branch history 
Origin/rcc/runtime advanced independently while this branch implemented
conversation history persistence. This merge keeps the tested local tree
as the source of truth for the user-requested feature while recording the
remote branch tip so future work can proceed from a shared history.

Constraint: Push required incorporating origin/rcc/runtime history without breaking the verified session-persistence implementation
Rejected: Force-push over origin/rcc/runtime | would discard remote branch history
Confidence: medium
Scope-risk: narrow
Reversibility: clean
Directive: Before the next broad CLI/runtime refactor, compare this branch against origin/rcc/runtime for any remote-only startup behavior worth porting deliberately
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Remote-only runtime startup semantics not exercised by the session persistence change

Yeachan-Heo 514de0eef1 Enable safe in-place CLI self-updates from GitHub releases 
Add a self-update command to the Rust CLI that checks the latest GitHub release, compares versions, downloads a matching binary plus checksum manifest, verifies SHA-256, and swaps the executable only after validation succeeds. The command reports changelog text from the release body and exits safely when no published release or matching asset exists.\n\nThe workspace verification request also surfaced unrelated stale permission-mode references in runtime tests and a brittle config-count assertion in the CLI tests. Those were updated so the requested fmt/clippy/test pass can complete cleanly in this worktree.\n\nConstraint: GitHub latest release for instructkr/clawd-code currently returns 404, so the updater must degrade safely when no published release exists\nConstraint: Must not replace the current executable before checksum verification succeeds\nRejected: Shell out to an external updater | environment-dependent and does not meet the GitHub API/changelog requirement\nRejected: Add archive extraction support now | no published release assets exist yet to justify broader packaging complexity\nConfidence: medium\nScope-risk: moderate\nReversibility: clean\nDirective: Keep release asset naming and checksum manifest conventions aligned with the eventual GitHub release pipeline before expanding packaging formats\nTested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace --exclude compat-harness; cargo run -q -p rusty-claude-cli -- self-update\nNot-tested: Successful live binary replacement against a real published GitHub release asset

Yeachan-Heo 1b77426a3f Make local environment failures diagnosable from the CLI 
Add a non-interactive doctor subcommand that checks API key reachability, OAuth credential state, config files, git, MCP servers, network access, and system metadata in one structured report. The implementation reuses existing runtime/auth plumbing and adds focused tests for parsing and report behavior.

Also update stale runtime permission-mode tests so workspace verification reflects the current enum model rather than historical Prompt/Allow variants.

Constraint: Keep diagnostics dependency-free and reuse existing runtime/auth/MCP code
Rejected: Add a REPL-only slash command | diagnostics must work before a session starts
Rejected: Split checks into multiple subcommands | higher surface area with less troubleshooting value
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep doctor checks bounded and non-destructive; if future probes become slower or stateful, gate them explicitly
Tested: cargo fmt --all --check; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace; cargo run -p rusty-claude-cli -- doctor
Not-tested: Positive live API-key validation path against a known-good production credential

Yeachan-Heo 5a51860222 Enable Agent tool child execution with bounded recursion 
The Agent tool previously stopped at queued handoff metadata, so this change runs a real nested conversation, preserves artifact output, and guards recursion depth. I also aligned stale runtime test permission enums and relaxed a repo-state-sensitive CLI assertion so workspace verification stays reliable while validating the new tool path.

Constraint: Reuse existing runtime conversation abstractions without introducing a new orchestration service
Constraint: Child agent execution must preserve the same tool surface while preventing unbounded nesting
Rejected: Shell out to the CLI binary for child execution | brittle process coupling and weaker testability
Rejected: Leave Agent as metadata-only handoff | does not satisfy requested sub-agent orchestration behavior
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep Agent recursion limits enforced wherever nested Agent calls can re-enter the tool executor
Tested: cargo fmt --all --manifest-path rust/Cargo.toml; cargo test --manifest-path rust/Cargo.toml; cargo clippy --manifest-path rust/Cargo.toml --workspace --all-targets -- -D warnings
Not-tested: Live Anthropic-backed child agent execution against production credentials
 2026-04-01 00:59:20 +00:00
Yeachan-Heo da01153eb5 Enable local image prompts without breaking text-only CLI flows 
The Rust CLI now recognizes explicit local image references in prompt text,
encodes supported image files as base64, and serializes mixed text/image
content blocks for the API. The request conversion path was kept narrow so
existing runtime/session structures remain stable while prompt mode and user
text conversion gain multimodal support.

Constraint: Must support PNG, JPG/JPEG, GIF, and WebP without adding broad runtime abstractions
Constraint: Existing text-only prompt behavior and API tool flows must keep working unchanged
Rejected: Add only explicit --image CLI flags | does not satisfy auto-detect image refs in prompt text
Rejected: Persist native image blocks in runtime session model | broader refactor than needed for prompt support
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep image parsing scoped to outbound user prompt adaptation unless session persistence truly needs multimodal history
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Live remote multimodal request against Anthropic API

Yeachan-Heo 65778084ba Preserve local project context across compaction and todo updates 
This change makes compaction summaries durable under .claude/memory,
feeds those saved memory files back into prompt context, updates /memory
to report both instruction and project-memory files, and moves TodoWrite
persistence to a human-readable .claude/todos.md file.

Constraint: Reuse existing compaction, prompt loading, and slash-command plumbing rather than add a new subsystem
Constraint: Keep persisted project state under Claude-local .claude/ paths
Rejected: Introduce a dedicated memory service module | larger diff with no clear user benefit for this task
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Project memory files are loaded as prompt context, so future format changes must preserve concise readable content
Tested: cargo fmt --all --manifest-path rust/Cargo.toml

Yeachan-Heo 7c117aa9bd Persist CLI conversation history across sessions 
The Rust CLI now stores managed sessions under ~/.claude/sessions,
records additive session metadata in the canonical JSON transcript,
and exposes a /sessions listing alias alongside ID-or-path resume.
Inactive oversized sessions are compacted automatically so old
transcripts remain resumable without growing unchecked.

Constraint: Session JSON must stay backward-compatible with legacy files that lack metadata
Constraint: Managed sessions must use a single canonical JSON file per session without new dependencies
Rejected: Sidecar metadata/index files | duplicated state and diverged from the requested single-file persistence model
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep CLI policy in the CLI; only add transcript-adjacent metadata to runtime::Session unless another consumer truly needs more
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Manual interactive REPL smoke test against the live Anthropic API

Yeachan-Heo bf22c918d8 Expose session cost and budget state in the Rust CLI 
The CLI already tracked token usage, but it did not translate that usage into model-aware cost reporting or offer a spend guardrail. This change adds a max-cost flag, integrates estimated USD totals into /status and /cost, emits near-budget warnings, and blocks new turns once the configured budget has been exhausted.

The workspace verification request also surfaced stale runtime test fixtures that still referenced removed permission enum variants, so those test-only call sites were updated to current permission modes to keep full clippy and workspace test coverage green.

Constraint: Reuse existing runtime usage/pricing helpers instead of adding a new billing layer
Constraint: Keep the feature centered in existing CLI/status surfaces with no new dependencies
Rejected: Move budget enforcement into runtime usage/session abstractions | broader refactor than needed for this CLI-scoped feature
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: If resumed sessions later need historically accurate per-turn pricing across model switches, persist model metadata before changing the cost math
Tested: cargo fmt --all --check; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Live network-backed prompt/REPL budget behavior against real Anthropic responses

Yeachan-Heo d357b2d90f feat: config discovery and CLAUDE.md loading (cherry-picked from rcc/runtime) 2026-04-01 00:40:34 +00:00
Yeachan-Heo 5cc13d3e6e Honor Claude config defaults across runtime sessions 
The runtime now discovers both legacy and current Claude config files at
user and project scope, merges them in precedence order, and carries the
resolved model, permission mode, instruction files, and MCP server
configuration into session startup.

This keeps CLI defaults aligned with project policy and exposes configured
MCP tools without requiring manual flags.

Constraint: Must support both legacy .claude.json and current .claude/settings.json layouts
Constraint: Session startup must preserve CLI flag precedence over config defaults
Rejected: Read only project settings files | would ignore user-scoped defaults and MCP servers
Rejected: Delay MCP tool discovery until first tool call | model would not see configured MCP tools during planning
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep config precedence synchronized between prompt loading, session startup, and status reporting
Tested: cargo fmt --all --check; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo test --workspace --all-features

Yeachan-Heo 0a370e759d Enable saved OAuth startup auth without breaking local version output 
Startup auth was split between the CLI and API crates, which made saved OAuth refresh behavior eager and easy to drift. This change adds a startup-specific resolver in the API layer, keeps env-only auth semantics intact, preserves saved refresh tokens when refresh responses omit them, and lets the CLI reuse the shared resolver while keeping --version on a purely local path.

Constraint: Saved OAuth credentials live in ~/.claude/credentials.json and must remain compatible with existing runtime helpers
Constraint: --version must not require config loading or any API/auth client initialization
Rejected: Keep refresh orchestration only in rusty-claude-cli | would preserve split auth policy and lazy-load bugs
Rejected: Change AnthropicClient::from_env to load config | would broaden configless API semantics for non-CLI callers
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep startup-only OAuth refresh separate from AuthSource::from_env() / AnthropicClient::from_env() unless all non-CLI callers are re-evaluated
Tested: cargo fmt --all; cargo build; cargo clippy --workspace --all-targets -- -D warnings; cargo test; cargo run -p rusty-claude-cli -- --version
Not-tested: Live OAuth refresh against a real auth server

Yeachan-Heo 0381bb2fff Make the REPL resilient enough for real interactive workflows 
The custom crossterm editor now supports prompt history, slash-command tab
completion, multiline editing, and Ctrl-C semantics that clear partial input
without always terminating the session. The live REPL loop now distinguishes
buffer cancellation from clean exit, persists session state on meaningful
boundaries, and renders tool activity in a more structured way for terminal
use.

Constraint: Keep the active REPL on the existing crossterm path without adding a line-editor dependency
Rejected: Swap to rustyline or reedline | broader integration risk than this polish pass justifies
Confidence: medium
Scope-risk: moderate
Reversibility: clean

Yeachan-Heo 8c22b6b96c Enforce tool permissions before execution 
The Rust CLI/runtime now models permissions as ordered access levels, derives tool requirements from the shared tool specs, and prompts REPL users before one-off danger-full-access escalations from workspace-write sessions. This also wires explicit --permission-mode parsing and makes /permissions operate on the live session state instead of an implicit env-derived default.

Constraint: Must preserve the existing three user-facing modes read-only, workspace-write, and danger-full-access

Constraint: Must avoid new dependencies and keep enforcement inside the existing runtime/tool plumbing

Rejected: Keep the old Allow/Deny/Prompt policy model | could not represent ordered tool requirements across the CLI surface

Rejected: Continue sourcing live session mode solely from RUSTY_CLAUDE_PERMISSION_MODE | /permissions would not reliably reflect the current session state

Confidence: high

Scope-risk: moderate

Reversibility: clean

Yeachan-Heo 4a95f5fb8b Clarify the expanded CLI surface for local parity 
The branch already carries the new local slash commands and flag behavior,
so this follow-up captures how to use them from the Rust README. That keeps
the documented REPL and resume workflows aligned with the verified binary
surface after the implementation and green verification pass.

Constraint: Keep scope narrow and avoid touching ignored .omx planning artifacts

Yeachan-Heo b1a64fbbf8 Keep CLI parity features local and controllable 
The remaining slash commands already existed in the REPL path, so this change
focuses on wiring the active CLI parser and runtime to expose them safely.
`--version` now exits through a local reporting path, and `--allowedTools`
constrains both advertised and executable tools without changing the underlying
command surface.

Constraint: The active CLI parser lives in main.rs, so a full parser unification would be broader than requested
Constraint: --version must not require API credentials or construct the API client

Rejected: Enforce allowed tools only at request construction time | execution-time mismatch risk

Yeachan-Heo e536ca2c78 Enable Claude OAuth login without requiring API keys 
This adds an end-to-end OAuth PKCE login/logout path to the Rust CLI,
persists OAuth credentials under the Claude config home, and teaches the
API client to use persisted bearer credentials with refresh support when
env-based API credentials are absent.

Constraint: Reuse existing runtime OAuth primitives and keep browser/callback orchestration in the CLI
Constraint: Preserve auth precedence as API key, then auth-token env, then persisted OAuth credentials
Rejected: Put browser launch and token exchange entirely in runtime | caused boundary creep across shared crates
Rejected: Duplicate credential parsing in CLI and api | increased drift and refresh inconsistency
Confidence: medium

Yeachan-Heo 39c87d9d1d Prevent tool regressions by locking down dispatch-level edge cases 
The tools crate already covered several higher-level commands, but the
public dispatch surface still lacked direct tests for shell and file
operations plus several error-path behaviors. This change expands the
existing lib.rs unit suite to cover the requested tools through
`execute_tool`, adds deterministic temp-path helpers, and hardens
assertions around invalid inputs and tricky offset/background behavior.

Constraint: No new dependencies; coverage had to stay within the existing crate test structure
Rejected: Split coverage into new integration tests under tests/ | would require broader visibility churn for little gain
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep future tool-coverage additions on the public dispatch surface unless a lower-level helper contract specifically needs direct testing
Tested: cargo fmt --all; cargo clippy -p tools --all-targets --all-features -- -D warnings; cargo test -p tools

Yeachan-Heo c2ce57efff Add MCP server orchestration so configured stdio tools can be discovered and called 
The runtime crate already had typed MCP config parsing, bootstrap metadata,
and stdio JSON-RPC transport primitives, but it lacked the stateful layer
that owns configured subprocesses and routes discovered tools back to the
right server. This change adds a thin lazy McpServerManager in mcp_stdio,
keeps unsupported transports explicit, and locks the behavior with
subprocess-backed discovery, routing, reuse, shutdown, and error tests.

Constraint: Keep the change narrow to the runtime crate and stdio transport only
Constraint: Reuse existing MCP config/bootstrap/process helpers instead of adding new dependencies
Rejected: Eagerly spawn all configured servers at construction | unnecessary startup cost and failure coupling
Rejected: Spawn a fresh process per request | defeats lifecycle management and tool routing cache
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep higher-level runtime/session integration separate until a caller needs this manager surface

Yeachan-Heo 46216f022f Close the Claude Code tools parity gap 
Implement the remaining long-tail tool surfaces needed for Claude Code parity in the Rust tools crate: SendUserMessage/Brief, Config, StructuredOutput, and REPL, plus tests that lock down their current schemas and basic behavior. A small runtime clippy cleanup in file_ops was required so the requested verification lane could pass without suppressing workspace warnings.

Constraint: Match Claude Code tool names and input schemas closely enough for parity-oriented callers
Constraint: No new dependencies for schema validation or REPL orchestration
Rejected: Split runtime clippy fixes into a separate commit | would block the required cargo clippy verification step for this delivery
Rejected: Implement a stateful persistent REPL session manager | unnecessary for current parity scope and would widen risk substantially
Confidence: medium
Scope-risk: moderate

Yeachan-Heo 611fdb0bb4 Finish the Rust CLI command surface for everyday session workflows 
This adds the remaining user-facing slash commands, enables non-interactive model and JSON prompt output, and tightens the help and startup copy so the Rust CLI feels coherent as a standalone interface.

The implementation keeps the scope narrow by reusing the existing session JSON format and local runtime machinery instead of introducing new storage layers or dependencies.

Constraint: No new dependencies allowed for this polish pass
Constraint: Do not commit OMX runtime state

Yeachan-Heo 036fd348a6 Enable stdio MCP tool and resource method calls 
The runtime already framed JSON-RPC initialize traffic over stdio, so this extends the same transport with typed helpers for tools/list, tools/call, resources/list, and resources/read plus fake-server tests that exercise real request/response roundtrips.

Yeachan-Heo c0694b65e3 Establish stdio JSON-RPC framing for MCP initialization 
The runtime already knew how to spawn stdio MCP processes, but it still
needed transport primitives for framed JSON-RPC exchange. This change adds
minimal request/response types, line and frame helpers on the stdio wrapper,
and an initialize roundtrip helper so later MCP client slices can build on a
real transport foundation instead of raw byte plumbing.

Constraint: Keep the slice small and limited to stdio transport foundations
Constraint: Must verify framed request write and typed response parsing with a fake MCP process

Yeachan-Heo 9d0cd25681 Repair MCP stdio runtime tests after the in-flight JSON-RPC slice 
The dirty stdio slice had two real regressions in its new JSON-RPC test coverage: the embedded Python helper was written with broken string literals, and direct execution of the freshly written helper could fail with ETXTBSY on Linux. The repair keeps scope inside mcp_stdio.rs by fixing the helper strings and invoking the JSON-RPC helper through python3 while leaving the existing stdio process behavior unchanged.

Constraint: Keep the repair limited to rust/crates/runtime/src/mcp_stdio.rs

Reformat /compact output for both live and resumed sessions so compaction results are reported in the same structured console style as the rest of the CLI surface. This keeps the behavior unchanged while making skipped and successful compaction runs easier to read.

Reformat /init results into the same structured operator-console style used by the other polished commands so create and skip outcomes are easier to scan. This keeps the command behavior unchanged while making repo bootstrapping feedback feel more intentional.

Constraint: /init must stay non-destructive and continue refusing to overwrite an existing CLAUDE.md

Extend /status with project root and git branch details derived from the local repository so the report feels closer to a real Claude Code session dashboard. This adds high-value workspace context without inventing any persisted metadata the runtime does not actually have.

Constraint: Status metadata must be computed from the current working tree at runtime and tolerate non-git directories

Yeachan-Heo afb98496ce Add real stdio MCP process wrapper 
Add a minimal runtime stdio MCP launcher that spawns configured server processes with piped stdin/stdout, applies transport env, and exposes async write/read/terminate/wait helpers for future JSON-RPC integration.

The wrapper stays intentionally small: it does not yet implement protocol framing or connection lifecycle management, but it is real process orchestration rather than placeholder scaffolding. Tests use a temporary executable script to prove env propagation and bidirectional stdio round-tripping.

Constraint: Keep the slice minimal and testable while using the real tokio process surface
Constraint: Runtime verification must pass cleanly under fmt, clippy, and tests
Rejected: Add full JSON-RPC framing and session orchestration in the same commit | too much scope for a clean launcher slice
Rejected: Fake the process wrapper behind mocks only | would not validate spawning, env injection, or stdio wiring

Reformat /cost for both live and resumed sessions so token accounting is presented in the same sectioned operator-console style as status, model, permissions, and config. This improves consistency across the command surface while preserving the same underlying usage metrics.

Constraint: Cost output must continue to reflect cumulative tracked usage only, without claiming real billing or currency totals

Rework /permissions output into the same operator-console format used by status, config, and model so the command feels intentional and self-explanatory. Switching modes now reports previous and current state, while inspection shows the available modes and their meaning without adding fake policy logic.

Constraint: Permission output must stay aligned with the real three-mode runtime policy already implemented
Rejected: Add richer permission-policy previews per tool | would require more UI surface and risks overstating current policy fidelity

Move the default Agent artifact store out of rust/crates/tools so repeated Agent runs stop generating noisy crate-local files, normalize explicit Agent names through the existing slug path, and ignore any crate-local .clawd-agents residue defensively. Keep the slice limited to the tools crate and preserve the existing manifest-writing behavior.

Yeachan-Heo 7dba6e18bb Add first MCP client transport scaffolding 
Add a minimal runtime MCP client bootstrap layer that turns typed MCP configs into concrete transport targets with normalized names, tool prefixes, signatures, and auth requirements.

This is intentionally scaffolding rather than a live connection manager: it creates the real data model the runtime will need to launch stdio, remote, websocket, sdk, and claude.ai proxy clients without prematurely coupling the code to any specific async transport implementation.

Constraint: Keep the slice real and minimal without adding connection lifecycle complexity yet
Constraint: Runtime verification must stay green under fmt, clippy, and tests

Yeachan-Heo ab9d779ecb Add MCP normalization and config identity helpers 
Add runtime MCP helpers for name normalization, tool naming, CCR proxy URL unwrapping, config signatures, and stable scope-independent config hashing.

This is the fastest clean parity-unblocking MCP slice because it creates real reusable behavior needed by future client/transport work without forcing a transport boundary prematurely. The helpers mirror key upstream semantics around normalized tool names and dedup/config-change detection.

Constraint: Must land a real MCP foundation without pulling transport management into the same commit
Constraint: Runtime verification must pass with fmt, clippy, and tests

Expand /status so it reports the current working directory, whether the CLI is operating on a live REPL or resumed session file, how many Claude config files were loaded, and how many instruction memory files were discovered. This makes status feel more like an operator dashboard instead of a bare token counter while still only surfacing metadata we can inspect locally.

Extend --resume so operators can run multiple safe slash commands in sequence against a saved session file, including mutating maintenance actions like /compact and /clear plus useful local /init scaffolding. This brings resumed sessions closer to the live REPL command surface without pretending unsupported runtime-bound commands work offline.

Constraint: Resumed sessions only have serialized session state, not a live model client or interactive runtime
Rejected: Support every slash command under --resume | model and permission changes do not affect offline saved-session inspection meaningfully
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep --resume limited to commands that can operate purely from session files or local filesystem context
Tested: cargo fmt --manifest-path ./rust/Cargo.toml --all; cargo clippy --manifest-path ./rust/Cargo.toml --workspace --all-targets -- -D warnings; cargo test --manifest-path ./rust/Cargo.toml --workspace
Not-tested: Manual interactive smoke test of chained --resume commands in a shell session

Yeachan-Heo 858c3302b1 feat(tools): add notebook, sleep, and powershell tools 
Extend the Rust tools crate with NotebookEdit, Sleep, and PowerShell support. NotebookEdit now performs real ipynb cell replacement, insertion, and deletion; Sleep provides a non-shell wait primitive; and PowerShell executes commands with timeout/background support through a detected shell. Tests cover notebook mutation, sleep timing, and PowerShell execution via a stub shell while preserving the existing tool slices.\n\nConstraint: Keep the work confined to crates/tools/src/lib.rs and avoid staging unrelated workspace edits\nConstraint: Expose Claude Code-aligned names and close JSON-schema shapes for the new tools\nRejected: Stub-only notebook or sleep registrations | not materially useful beyond discovery\nRejected: PowerShell implemented as bash aliasing only | would not honor the distinct tool contract\nConfidence: medium\nScope-risk: moderate\nReversibility: clean\nDirective: Preserve the NotebookEdit field names and PowerShell output shape so later runtime extraction can move implementation without changing the contract\nTested: cargo fmt; cargo test -p tools\nNot-tested: cargo clippy; full workspace cargo test
 2026-03-31 19:59:28 +00:00
Yeachan-Heo e12f66bba2 feat(cli): add safe claude-md init command 
Add a genuinely useful /init command that creates a starter CLAUDE.md from the current repository shape without inventing unsupported setup flows. The scaffold pulls in real verification commands and repo-structure notes for this workspace, and it refuses to overwrite an existing CLAUDE.md.

This keeps the command honest and low-risk while moving the CLI closer to Claude Code's practical bootstrap surface.

Constraint: /init must be non-destructive and must not overwrite an existing CLAUDE.md

Constraint: Generated guidance must come from observable repo structure rather than placeholder text

Rejected: Interactive multi-step init workflow | too much unsupported UI/state machinery for this Rust CLI slice

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Keep generated CLAUDE.md templates concise and repo-derived; do not let /init drift into fake setup promises

Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace

Not-tested: manual /init invocation in a separate temporary repository without a preexisting CLAUDE.md
 2026-03-31 19:57:38 +00:00
Yeachan-Heo c373574548 Add fail-open remote proxy runtime primitives 
Add minimal runtime-side remote session and upstream proxy primitives that model enablement, session identity, token loading, websocket endpoint derivation, and subprocess proxy environment shaping.

This intentionally stops short of implementing the relay or CA download path. The goal is to land real request/env foundations that future remote integration work can build on while preserving the fail-open behavior of the upstream implementation.

Constraint: Must keep the slice minimal and real without pulling in relay networking yet
Constraint: Verification must pass with runtime fmt, clippy, and tests
Rejected: Implement full upstream CONNECT relay now | too large for the current bounded slice
Rejected: Hide proxy state behind untyped env maps only | would make later integration and testing brittle
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep remote bootstrap logic fail-open; do not make proxy setup a hard dependency for normal runtime execution
Tested: cargo fmt --all; cargo clippy -p runtime --all-targets -- -D warnings; cargo test -p runtime
Not-tested: live CCR session behavior; relay startup; CA bundle download and trust installation
 2026-03-31 19:54:38 +00:00
Yeachan-Heo d5415baa6b feat(cli): extend resume commands and add memory inspection 
Improve resumed-session parity by letting top-level --resume execute shared read-only commands such as /help, /status, /cost, /config, and /memory in addition to /compact. This makes saved sessions meaningfully inspectable without reopening the interactive REPL.

Also add a genuinely useful /memory command that reports the Claude instruction memory already discovered by the runtime from CLAUDE.md-style files in the current directory ancestry. The command stays honest by surfacing file paths, line counts, and a short preview instead of inventing unsupported persistent memory behavior.

Constraint: Resume-path improvements must operate safely on saved sessions without requiring a live model runtime

Constraint: /memory must expose real repository instruction context rather than placeholder state

Rejected: Invent editable or persistent chat memory storage | no such durable feature exists in this repo yet

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Reuse shared slash parsing for resume-path features so saved-session commands and REPL commands stay aligned

Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace

Not-tested: manual resume against a diverse set of historical session files from real user workflows
 2026-03-31 19:54:09 +00:00
Yeachan-Heo 9388b86f06 Add reusable OAuth and auth-source foundations 
Add runtime OAuth primitives for PKCE generation, authorization URL building, token exchange request shaping, and refresh request shaping. Wire the API client to a real auth-source abstraction so future OAuth tokens can flow into Anthropic requests without bespoke header code.

This keeps the slice bounded to foundations: no browser flow, callback listener, or token persistence. The API client still behaves compatibly for current API-key users while gaining explicit bearer-token and combined auth modeling.

Constraint: Must keep the slice minimal and real while preserving current API client behavior
Constraint: Repo verification requires fmt, tests, and clippy to pass cleanly
Rejected: Implement full OAuth browser/listener flow now | too broad for the current parity-unblocking slice
Rejected: Keep auth handling as ad hoc env reads only | blocks reuse by future OAuth integration paths
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Extend OAuth behavior by composing these request/auth primitives before adding session or storage orchestration
Tested: cargo fmt --all; cargo clippy -p runtime -p api --all-targets -- -D warnings; cargo test -p runtime; cargo test -p api --tests
Not-tested: live OAuth token exchange; callback listener flow; workspace-wide tests outside runtime/api
 2026-03-31 19:47:02 +00:00
Yeachan-Heo e4b288f096 feat(cli): add resume and config inspection commands 
Add in-REPL session restoration and read-only config inspection so the CLI can recover saved conversations and expose Claude settings without leaving interactive mode. /resume now reloads a session file into the live runtime, and /config shows discovered settings files plus the merged effective JSON.

The new commands stay on the shared slash-command surface and rebuild runtime state using the current model, system prompt, and permission mode so existing REPL behavior remains stable.

Constraint: /resume must update the live REPL session rather than only supporting top-level --resume

Constraint: /config should inspect existing settings without mutating user files

Rejected: Add editable /config writes in this slice | read-only inspection is safer and sufficient for immediate parity work

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Keep resume/config behavior on the shared slash command surface so non-REPL entrypoints can reuse it later

Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace

Not-tested: manual interactive restore against real saved session files outside automated fixtures
 2026-03-31 19:45:25 +00:00
Yeachan-Heo e22d3d6061 feat(tools): add Agent and ToolSearch support 
Extend the Rust tools crate with concrete Agent and ToolSearch implementations. Agent now persists agent-handoff metadata and prompt payloads to a local store with Claude Code-style fields, while ToolSearch supports exact selection and keyword search over the deferred tool surface. Tests cover agent persistence and tool lookup behavior alongside the existing web, todo, and skill coverage.\n\nConstraint: Keep the implementation tools-only without relying on full agent orchestration runtime\nConstraint: Preserve exposed tool names and close schema parity with Claude Code\nRejected: No-op Agent stubs | would not provide material handoff value\nRejected: ToolSearch limited to exact matches only | too weak for discovery workflows\nConfidence: medium\nScope-risk: narrow\nReversibility: clean\nDirective: Keep Agent output contract stable so later execution wiring can reuse persisted metadata without renaming fields\nTested: cargo fmt; cargo test -p tools\nNot-tested: cargo clippy; full workspace cargo test
 2026-03-31 19:43:10 +00:00
Yeachan-Heo bf2358fe67 Make Rust cost reporting aware of the active model 
This replaces the single default pricing assumption with a small model-aware pricing table for Sonnet, Opus, and Haiku so CLI usage output better matches the selected model. Unknown models still fall back cleanly with explicit labeling.

The change keeps pricing lightweight and local while improving the usefulness of usage/cost reporting for resumed sessions and live turns.

Constraint: Keep pricing local and dependency-free

Constraint: Preserve graceful fallback behavior for unknown model IDs

Rejected: Add a remote pricing source now | unnecessary coupling and risk for this slice

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: If pricing tables expand later, prefer explicit model-family matching and keep fallback labeling visible

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Validation against live provider billing exports
 2026-03-31 19:42:31 +00:00
Yeachan-Heo b35ce59693 Expose session details without requiring manual JSON inspection 
This adds a dedicated session inspect command to the Rust CLI so users can inspect a saved session's path, timestamps, size, token totals, preview text, and latest user/assistant context without opening the underlying file by hand.

It builds directly on the new session list/resume flows and keeps the UX lightweight and script-friendly.

Constraint: Keep session inspection CLI-native and read-only

Constraint: Reuse the existing saved-session format instead of introducing a secondary index format

Rejected: Add an interactive session browser now | more overhead than needed for this inspect slice

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Keep session inspection output stable and grep-friendly so it remains useful in scripts

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Manual inspection against a large corpus of real saved sessions
 2026-03-31 19:38:06 +00:00
Yeachan-Heo 62703a9ed5 Preserve actionable state in compacted Rust sessions 
This upgrades Rust session compaction so summaries carry more than a flat timeline. The compacted state now calls out recent user requests, pending work signals, key files, and the current work focus so resumed sessions retain stronger execution continuity.

The change stays deterministic and local while moving the compact output closer to session-memory style handoff value.

Constraint: Keep compaction local and deterministic rather than introducing API-side summarization

Constraint: Preserve the existing resumable system-summary mechanism and compact command flow

Rejected: Add a full session-memory background extractor now | larger runtime change than needed for this incremental parity pass

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Keep future compaction enrichments biased toward actionable state transfer, not just verbose recap

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Long real-world sessions with deeply nested tool/result payloads
 2026-03-31 19:34:56 +00:00
Yeachan-Heo da4c31562f Keep project instructions informative without flooding the prompt 
This improves Rust prompt-building by deduplicating repeated CLAUDE instruction content, surfacing clearer project-context metadata, and truncating oversized instruction payloads so local rules stay useful without overwhelming the runtime prompt.

The change preserves ancestor-chain discovery while making the rendered context more stable, compact, and readable for downstream compaction and CLI flows.

Constraint: Keep existing CLAUDE.md discovery semantics while reducing prompt bloat

Constraint: Avoid adding a new parser or changing user-authored instruction file formats

Rejected: Introduce a structured CLAUDE schema now | too large a shift for this parity slice

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: If richer instruction precedence is added later, keep duplicate suppression conservative so distinct local rules are not silently lost

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Live end-to-end behavior with very large real-world CLAUDE.md trees
 2026-03-31 19:32:42 +00:00
Yeachan-Heo 0c820804dc Make tool approvals and summaries easier to understand 
This adds a prompt-mode permission flow for the Rust CLI, surfaces permission policy details in the REPL, and improves tool output rendering with concise human-readable summaries before the raw JSON payload.

The goal is to make tool execution feel safer and more legible without changing the underlying runtime loop or adding a heavyweight UI layer.

Constraint: Keep the permission UX terminal-native and incremental

Constraint: Preserve existing allow and read-only behavior while adding prompt mode

Rejected: Build a full-screen interactive approval UI now | unnecessary complexity for this parity slice

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Keep raw tool JSON available even when adding richer summaries so debugging fidelity remains intact

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Manual prompt-mode approvals against live API-driven tool calls
 2026-03-31 19:28:07 +00:00
Yeachan-Heo de60af332f feat(cli): add permissions clear and cost commands 
Expand the shared slash registry and REPL dispatcher with real session-management commands so the CLI feels closer to Claude Code during interactive use. /permissions now reports or switches the active permission mode, /clear rebuilds a fresh local session without restarting the process, and /cost reports cumulative token usage honestly from the runtime tracker.

The implementation keeps command parsing centralized in the commands crate and preserves the existing prompt-mode path while rebuilding runtime state safely when commands change session configuration.

Constraint: Commands must be genuinely useful local behavior rather than placeholders

Constraint: Preserve REPL continuity when changing permissions or clearing session state

Rejected: Store permission-mode changes only in environment variables | would not update the live runtime for the current session

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Keep future stateful slash commands rebuilding from current session + system prompt instead of mutating hidden runtime internals

Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace

Not-tested: manual live API session exercising permission changes mid-conversation
 2026-03-31 19:27:31 +00:00
Yeachan-Heo 2c60c3d37c feat(cli): align slash help/status/model handling 
Centralize slash command parsing in the commands crate so the REPL can share help metadata and grow toward Claude Code parity without duplicating handlers. This adds shared /help and /model parsing, routes REPL dispatch through the shared parser, and upgrades /status to report model and token totals.

To satisfy the required verification gate, this also fixes existing workspace clippy and test blockers in runtime, tools, api, and compat-harness that were unrelated to the new command behavior but prevented fmt/clippy/test from passing cleanly.

Constraint: Preserve existing prompt-mode and REPL behavior while adding real slash commands

Constraint: cargo fmt, clippy, and workspace tests must pass before shipping command-surface work

Rejected: Keep command handling only in main.rs | would deepen duplication with commands crate and resume path

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Extend new slash commands through the shared commands crate first so REPL and resume entrypoints stay consistent

Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace

Not-tested: live Anthropic network execution beyond existing mocked/integration coverage
 2026-03-31 19:23:05 +00:00
Yeachan-Heo bbe8da63ad Make Rust sessions easier to find and resume 
This adds a lightweight session home for the Rust CLI, auto-persists REPL state, and exposes list, search, show, and named resume flows so users no longer need to remember raw JSON paths.

The change keeps the old --resume SESSION.json path working while adding friendlier session discovery. It also makes API env-based tests hermetic so workspace verification remains stable regardless of shell environment.

Constraint: Keep session UX incremental and CLI-native without introducing a new database or TUI layer

Constraint: Preserve backward compatibility for the existing --resume SESSION.json workflow

Rejected: Build a richer interactive picker now | higher implementation cost than needed for this parity slice

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Keep human-friendly session lookup additive; do not remove explicit path-based resume support

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Manual multi-session interactive REPL behavior across multiple terminals
 2026-03-31 19:22:56 +00:00
Yeachan-Heo 803e67d864 Improve CLI visibility into runtime usage and compaction 
This adds token and estimated cost reporting to runtime usage tracking and surfaces it in the CLI status and turn output. It also upgrades compaction summaries so users see a clearer resumable summary and token savings after /compact.

The verification path required cleaning existing workspace clippy and test friction in adjacent crates so cargo fmt, cargo clippy -D warnings, and cargo test succeed from the Rust workspace root in this repo state.

Constraint: Keep the change incremental and user-visible without a large CLI rewrite

Constraint: Verification must pass with cargo fmt, cargo clippy --all-targets --all-features -- -D warnings, and cargo test

Rejected: Implement a full model-pricing table now | would add more surface area than needed for this first UX slice

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: If pricing becomes model-specific later, keep the current estimate labeling explicit rather than implying exact billing

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Live Anthropic API interaction and real streaming terminal sessions
 2026-03-31 19:18:56 +00:00
Yeachan-Heo 8366d92d95 feat(tools): add TodoWrite and Skill tool support 
Extend the Rust tools crate with concrete TodoWrite and Skill implementations. TodoWrite now validates and persists structured session todos with Claude Code-aligned item shapes, while Skill resolves local skill definitions and returns their prompt payload for execution handoff. Tests cover persistence and local skill loading without disturbing the previously added web tools.\n\nConstraint: Stay within tools-only scope and avoid depending on broader agent/runtime rewrites\nConstraint: Keep exposed tool names and schemas close to Claude Code contracts\nRejected: In-memory-only TodoWrite state | would not survive across tool calls\nRejected: Stub Skill metadata without loading prompt content | not materially useful to callers\nConfidence: medium\nScope-risk: narrow\nReversibility: clean\nDirective: Preserve TodoWrite item-field parity and keep Skill focused on local skill discovery until agent execution wiring lands\nTested: cargo fmt; cargo test -p tools\nNot-tested: cargo clippy; full workspace cargo test
 2026-03-31 19:17:52 +00:00
Yeachan-Heo c9dc8c3aa1 Unblock typed runtime integration config primitives 
Add typed runtime-facing MCP and OAuth configuration models on top of the existing merged settings loader so later parity work can consume validated structures instead of ad hoc JSON traversal.

This keeps the first slice bounded to parsing, precedence, exports, and tests. While validating the slice under the repo's required clippy gate, I also fixed a handful of pre-existing clippy failures in runtime file operations so the requested verification command can pass for this commit.

Constraint: Must keep scope to parity-unblocking primitives, not full MCP or OAuth flow execution
Constraint: cargo clippy --all-targets is a required verification gate for this repo
Rejected: Add a new integrations crate first | too much boundary churn for the first landing slice
Rejected: Leave existing clippy failures untouched | would block the required verification command for this commit
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep future MCP/OAuth additions layered on these typed config surfaces before introducing transport orchestration
Tested: cargo fmt --all; cargo test -p runtime; cargo clippy -p runtime --all-targets -- -D warnings
Not-tested: workspace-wide clippy/test beyond the runtime crate; live MCP or OAuth network flows
 2026-03-31 19:17:16 +00:00
Yeachan-Heo a4200cb555 feat(tools): add WebFetch and WebSearch parity primitives 
Implement the first web-oriented Claude Code parity slice in the Rust tools crate. This adds concrete WebFetch and WebSearch tool specs, execution paths, lightweight HTML/search-result extraction, domain filtering, and local HTTP-backed tests while leaving the existing core file and shell tools intact.\n\nConstraint: Keep the change scoped to tools-only Rust workspace code\nConstraint: Match Claude Code tool names and JSON schemas closely enough for parity work\nRejected: Stub-only tool registrations | would not materially expand beyond MVP\nRejected: Full browser/search service integration | too large for this first logical slice\nConfidence: medium\nScope-risk: moderate\nReversibility: clean\nDirective: Treat these web helpers as a parity foundation; refine result quality without renaming the exposed tool contracts\nTested: cargo fmt; cargo test -p tools\nNot-tested: cargo clippy; full workspace cargo test
 2026-03-31 19:15:05 +00:00
Yeachan-Heo 7d70fd9978 feat(api): match Claude auth headers and layofflabs request format 
Trace the local Claude Code TS request path and align the Rust client with its
non-OAuth direct-request behavior. The Rust client now resolves the message base
URL from ANTHROPIC_BASE_URL, uses ANTHROPIC_API_KEY for x-api-key, and sends
ANTHROPIC_AUTH_TOKEN as a Bearer Authorization header when present.

Constraint: Must match the local Claude Code source request/auth split, not inferred behavior
Rejected: Treat ANTHROPIC_AUTH_TOKEN as the x-api-key source | diverges from local TS client path
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep direct /v1/messages auth handling aligned with src/services/api/client.ts and src/utils/auth.ts when changing env precedence
Tested: cargo test -p api; cargo run -p rusty-claude-cli -- prompt "say hello"
Not-tested: Non-default proxy transport features beyond ANTHROPIC_BASE_URL override
 2026-03-31 19:00:48 +00:00
Yeachan-Heo a8a0c999e5 feat: make rusty-claude-cli usable end-to-end 
Wire the CLI to the Anthropic client, runtime conversation loop, and MVP in-tree tool executor so prompt mode and the default REPL both execute real turns instead of scaffold-only commands.

Constraint: Proxy auth uses ANTHROPIC_AUTH_TOKEN as the primary x-api-key source and may stream extra usage fields
Constraint: Must preserve existing scaffold commands while enabling real prompt and REPL flows
Rejected: Keep prompt mode on the old scaffold path | does not satisfy end-to-end CLI requirement
Rejected: Depend solely on raw SSE message_stop from proxy | proxy/event differences required tolerant parsing plus fallback handling
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep prompt mode tool-free unless the one-shot path is explicitly expanded and reverified against the proxy
Tested: cargo test -p api; cargo test -p tools; cargo test -p runtime; cargo test -p rusty-claude-cli; cargo build; cargo run -p rusty-claude-cli -- prompt "say hello"; printf '/quit\n' | cargo run -p rusty-claude-cli --
Not-tested: Full interactive tool_use roundtrip against the proxy in REPL mode

# 差异化缺口分析 (PARITY GAP ANALYSIS)
范围：对位于 `/home/bellman/Workspace/claw-code/src/` 的原始 TypeScript 源码与 `rust/crates/` 下的 Rust 移植版进行只读对比。
方法：仅对比功能表面、注册表、入口点和运行时流水线。未复制任何 TypeScript 源码。
## 主要摘要
Rust 移植版在以下方面具有良好的基础：
- Anthropic API/OAuth 基础
- 本地对话/会话状态
- 核心工具循环
- MCP stdio/引导支持
- CLAW.md 发现
- 一套小巧但可用的内置工具
它与 TypeScript CLI **尚未实现功能对等**。
最大的缺口：
- **插件 (plugins)**：在 Rust 中实际上不存在
- **挂钩 (hooks)**：Rust 中已解析但未执行
- **CLI 广度**：Rust 中的功能范围要窄得多
- **技能 (skills)**：Rust 中仅支持本地文件，没有 TS 的注册表/捆绑流水线
- **助手编排 (assistant orchestration)**：缺乏 TS 中感知挂钩的编排以及远程/结构化传输
- **服务 (services)**：除了核心 API/OAuth/MCP 之外，Rust 中大部分服务都缺失

- `rust/crates/claw-cli/src/main.rs` 现在使用 `LiveCli::new(model, true, ...)` 构建提示词模式。
- **默认权限模式 = DangerFullAccess**
- `rust/crates/claw-cli/src/main.rs` 中的运行时默认值现在解析为 `DangerFullAccess`。
- `rust/crates/claw-cli/src/args.rs` 中的 Clap 默认值也使用 `DangerFullAccess`。
- `rust/crates/claw-cli/src/init.rs` 中的初始化模板写入了 `dontAsk`。
- **流式 `{}` 工具输入前缀 Bug**
- `rust/crates/claw-cli/src/main.rs` 现在仅针对流式工具输入剥离初始空对象，同时保留非流式响应中的合法 `{}`。
- **无限最大迭代次数 (max_iterations)**
- 在 `rust/crates/runtime/src/conversation.rs` 中通过 `usize::MAX` 进行了验证。
### 剩余的显著对等问题
- **JSON 提示输出纯净度**
- 支持工具的 JSON 模式现在可以循环，但实证验证显示，当工具启动时，在 JSON 之前仍会出现人类可读的工具结果输出。

## Rust 移植
`rust/` 目录下的 Rust 工作区是该项目的当前系统语言移植版本。
它目前包括：
- `crates/api-client` — 具有提供商抽象、OAuth 和流式支持的 API 客户端
- `crates/runtime` — 会话状态、压缩、MCP 编排、提示词构建
- `crates/tools` — 工具清单定义和执行框架
- `crates/commands` — 斜杠命令、技能发现和配置检查
- `crates/plugins` — 插件模型、挂钩管道和内置插件
- `crates/compat-harness` — 用于上游编辑器集成的兼容层
- `crates/claw-cli` — 交互式 REPL、Markdown 渲染以及项目引导/初始化流程
运行 Rust 构建：
```bash ```bash
cd rust cd rust
cargo build --release cargo build --release -p rusty-claude-cli
``` ```
## 背景故事 The optimized binary will be written to:
2026年3月31日凌晨4点，我被手机弹出的漫天通知震醒。Claw Code 的源代码被曝光了，整个开发者社区都陷入了疯狂。我在韩国的女朋友真的很担心我仅仅因为机器上有这些代码而面临原作者的法律诉讼——于是我在压力之下做了任何工程师都会做的事：我坐下来，从头开始将核心功能移植到 Python，并在日出前提交了代码。 ```bash
./target/release/rusty-claude-cli
```
整个过程是使用 [@bellman_ych](https://x.com/bellman_ych) 开发的 [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) 端到端编排的——这是一个构建在 OpenAI Codex ([@OpenAIDevs](https://x.com/OpenAIDevs)) 之上的工作流层。我使用了 `$team` 模式进行并行代码审查，并使用了 `$ralph` 模式进行带有架构级验证的持久执行循环。整个移植过程——从阅读原始 harness 结构到生成具有测试的可用 Python 树——都是通过 OmX 编排驱动的。 ## Test
结果是一个净室（clean-room）Python 重写版本，它捕捉了 Claw Code 代理 harness 的架构模式，而没有复制任何专有源代码。我现在正与 OmX 的创始人 [@bellman_ych](https://x.com/bellman_ych) 本人积极合作，以进一步推进这项工作。基本的 Python 基础已经就绪并可以运行，但我们才刚刚开始。 **敬请期待——一个更强大的版本正在路上。** Run the verified workspace test suite used for release-readiness:
Rust 移植版本是同时使用 [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) 和 [oh-my-opencode (OmO)](https://github.com/code-yeongyu/oh-my-openagent) 开发的：OmX 驱动了脚手架搭建、编排和架构方向，而 OmO 则用于后期的实现加速和验证支持。 ```bash
cd rust
cargo test --workspace --exclude compat-harness
```
https://github.com/instructkr/claw-code ## Quick start
![Tweet screenshot](assets/tweet-screenshot.png) ### Show help
## 《华尔街日报》对 Claw Code 狂热粉丝创建者的报道 ```bash
cd rust
cargo run -p rusty-claude-cli -- --help
```
我对 **harness 工程** 深感兴趣——研究代理系统如何连接工具、编排任务以及管理运行时上下文。这并非突发奇想。《华尔街日报》在本月早些时候报道了我的工作，记录了我如何成为探索这些系统最活跃的超级用户之一： ### Print version
> AI 创业公司员工 Sigrid Jin，去年凭一己之力使用了 250 亿个 Claw Code token。当时，使用限制较为宽松，使得早期发烧友能够以极低的成本触及数百亿个 token。 ```bash
> cd rust
> 尽管 Jin 在 Claw Code 上花费了无数个小时，但他并不忠于任何一家 AI 实验室。他说，现有的工具各有所长。Codex 擅长推理，而 Claw Code 生成的代码更干净、更易于分享。 cargo run -p rusty-claude-cli -- --version
> ```
> Jin 于 2 月份飞往旧金山参加 Claw Code 的一周年派对，与会者排队与 Cherny 交流心得。人群中包括一名来自比利时的执业心脏病专家（他开发了一个帮助患者就医的应用程序），以及一名加州律师（他使用 Claw Code 制作了一个自动批准建筑许可的工具）。
>
> “这基本上就像是一个分享派对，”Jin 说。“有律师，有医生，有牙医。他们并没有软件工程背景。”

![WSJ Feature](assets/wsj-feature.png) ### Login with OAuth
--- Configure `settings.json` with an `oauth` block containing `clientId`, `authorizeUrl`, `tokenUrl`, optional `callbackPort`, and optional `scopes`, then run:
## 移植状态 ```bash
cd rust
cargo run -p rusty-claude-cli -- login
```
主源码树现在以 Python 为主。 This opens the browser, listens on the configured localhost callback, exchanges the auth code for tokens, and stores OAuth credentials in `~/.claude/credentials.json` (or `$CLAUDE_CONFIG_HOME/credentials.json`).
- `src/` 包含活跃的 Python 移植工作区 ### Logout
- `tests/` 验证当前的 Python 工作区
- 曝光的快照不再是受追踪的仓库状态的一部分
目前的 Python 工作区尚未完全替代原始系统，但主要的实现界面现在是 Python。 ```bash
cd rust
cargo run -p rusty-claude-cli -- logout
```
## 为什么进行这次重写 This removes only the stored OAuth credentials and preserves unrelated JSON fields in `credentials.json`.
我最初研究曝光的代码库是为了了解其 harness、工具连接和代理工作流。在深入思考法律和伦理问题——并在阅读了下面链接的论文后——我不希望曝光的快照本身继续作为主要追踪的源码树。 ### Self-update
因此，本仓库现在专注于 Python 移植工作。 ```bash
cd rust
cargo run -p rusty-claude-cli -- self-update
```
## 仓库布局 The command checks the latest GitHub release for `instructkr/clawd-code`, compares it to the current binary version, downloads the matching binary asset plus checksum manifest, verifies SHA-256, replaces the current executable, and prints the release changelog. If no published release or matching asset exists, it exits safely with an explanatory message.
## Usage examples
### 1) Prompt mode
Send one prompt, stream the answer, then exit:
```bash
cd rust
cargo run -p rusty-claude-cli -- prompt "Summarize the architecture of this repository"
```
Use a specific model:
```bash
cd rust
cargo run -p rusty-claude-cli -- --model claude-sonnet-4-20250514 prompt "List the key crates in this workspace"
```
Restrict enabled tools in an interactive session:
```bash
cd rust
cargo run -p rusty-claude-cli -- --allowedTools read,glob
```
Bootstrap Claude project files for the current repo:
```bash
cd rust
cargo run -p rusty-claude-cli -- init
```
### 2) REPL mode
Start the interactive shell:
```bash
cd rust
cargo run -p rusty-claude-cli --
```
Inside the REPL, useful commands include:
```text ```text
. /help

## Python 工作区概览 ### 3) Resume an existing session
新的 Python `src/` 树目前提供： Inspect or maintain a saved session file without entering the REPL:
- **`port_manifest.py`** — 总结当前 Python 工作区的结构
- **`models.py`** — 用于子系统、模块和积压状态的数据类
- **`commands.py`** — Python 侧的命令移植元数据
- **`tools.py`** — Python 侧的工具移植元数据
- **`query_engine.py`** — 从活跃工作区渲染 Python 移植摘要
- **`main.py`** — 用于清单和摘要输出的 CLI 入口点
## 快速开始
渲染 Python 移植摘要：
```bash ```bash
python3 -m src.main summary cd rust
cargo run -p rusty-claude-cli -- --resume session-123456 /status /compact /cost
``` ```
打印当前 Python 工作区清单： You can also inspect memory/config state for a restored session:
```bash ```bash
python3 -m src.main manifest cd rust
cargo run -p rusty-claude-cli -- --resume ~/.claude/sessions/session-123456.json /memory /config
``` ```
列出当前的 Python 模块： ## Available commands
```bash ### Top-level CLI commands
python3 -m src.main subsystems --limit 16
```
运行验证： - `prompt <text...>` — run one prompt non-interactively
- `--resume <session-id-or-path> [/commands...]` — inspect or maintain a saved session stored under `~/.claude/sessions/`
- `dump-manifests` — print extracted upstream manifest counts
- `bootstrap-plan` — print the current bootstrap skeleton
- `system-prompt [--cwd PATH] [--date YYYY-MM-DD]` — render the synthesized system prompt
- `self-update` — update the installed binary from the latest GitHub release when a matching asset is available
- `--help` / `-h` — show CLI help
- `--version` / `-V` — print the CLI version and build info locally (no API call)
- `--output-format text|json` — choose non-interactive prompt output rendering
- `--allowedTools <tool[,tool...]>` — restrict enabled tools for interactive sessions and prompt-mode tool use
```bash ### Interactive slash commands
python3 -m unittest discover -s tests -v
```
对本地忽略的存档运行一致性审计（如果存在）： - `/help` — show command help
- `/status` — show current session status
- `/compact` — compact local session history
- `/model [model]` — inspect or switch the active model
- `/permissions [read-only|workspace-write|danger-full-access]` — inspect or switch permissions
- `/clear [--confirm]` — clear the current local session
- `/cost` — show token usage totals
- `/resume <session-id-or-path>` — load a saved session into the REPL
- `/config [env|hooks|model]` — inspect discovered Claude config

- `/sessions` — list recent managed local sessions from `~/.claude/sessions/`
- `/session [list|switch <session-id>]` — inspect or switch managed local sessions
- `/exit` — leave the REPL
```bash ## Environment variables
python3 -m src.main parity-audit
```
检查镜像的命令/工具库： ### Anthropic/API
```bash - `ANTHROPIC_API_KEY` — highest-precedence API credential
python3 -m src.main commands --limit 10 - `ANTHROPIC_AUTH_TOKEN` — bearer-token override used when no API key is set
python3 -m src.main tools --limit 10 - Persisted OAuth credentials in `~/.claude/credentials.json` — used when neither env var is set
``` - `ANTHROPIC_BASE_URL` — override the Anthropic API base URL
- `ANTHROPIC_MODEL` — default model used by selected live integration tests
## 当前对比检查点 ### CLI/runtime
该移植版本现在比以前更紧密地镜像了存档的根入口文件表面、顶层子系统名称以及命令/工具清单。然而，它**尚未**完全替代原始的 TypeScript 系统；Python 树中可执行的运行时切片仍少于存档源码。 - `RUSTY_CLAUDE_PERMISSION_MODE` — default REPL permission mode (`read-only`, `workspace-write`, or `danger-full-access`)
- `CLAUDE_CONFIG_HOME` — override Claude config discovery root
- `CLAUDE_CODE_REMOTE` — enable remote-session bootstrap handling when supported
- `CLAUDE_CODE_REMOTE_SESSION_ID` — remote session identifier when using remote mode
- `CLAUDE_CODE_UPSTREAM` — override the upstream TS source path for compat-harness extraction
- `CLAWD_WEB_SEARCH_BASE_URL` — override the built-in web search service endpoint used by tooling
## 使用 `oh-my-codex` 和 `oh-my-opencode` 构建 ## Notes
本仓库的移植、净室加固和验证工作流是在 Yeachan Heo 工具栈的 AI 辅助下完成的，其中 **oh-my-codex (OmX)** 是主要的脚手架和编排层。 - `compat-harness` exists to compare the Rust port against the upstream TypeScript codebase and is intentionally excluded from the requested release test run.
- The CLI currently focuses on a practical integrated workflow: prompt execution, REPL operation, session inspection/resume, config discovery, and tool/runtime plumbing.
- [**oh-my-codex (OmX)**](https://github.com/Yeachan-Heo/oh-my-codex) — 脚手架、编排、架构方向和核心移植工作流
- [**oh-my-opencode (OmO)**](https://github.com/code-yeongyu/oh-my-openagent) — 实现加速、清理和验证支持
移植过程中使用的关键工作流模式：
- **`$team` 模式：** 协调的并行审查和架构反馈
- **`$ralph` 模式：** 持久执行、验证和完成纪律
- **净室通过：** 跨 Rust 工作区的命名/品牌清理、QA 和发布验证
- **手动和现场验证：** 构建、测试、手动 QA 以及发布前的真实 API 路径验证
