Dogfooded 2026-04-18 on main HEAD 7447232 from /tmp/cdY.
Two-path-diverge problem:
A. /export slash command (resolve_export_path at main.rs:5990-6010):
- If extension != 'txt', silently appends '.txt'
- /export foo.md → writes foo.md.txt
- /export report.json → writes report.json.txt
- cwd.join(relative_path_with_dotdot) resolves outside cwd
- No path-traversal rejection
B. claw export CLI (run_export at main.rs:6021-6055):
- fs::write(path, &markdown) directly, no suffix munging
- /tmp/cli-export.md → writes /tmp/cli-export.md
- Also no path-traversal check, absolute paths write wherever
Same logical action, incompatible output contracts. A claw that
switches between /export and claw export sees different output
filenames for the same input.
Compounded:
- Content is Markdown (render_session_markdown emits '# Conversation
Export', '## 1. User', fenced code blocks) but slash path forces
.txt extension → content/extension mismatch. File-routing
pipelines (archival by extension, syntax highlight, preview)
misclassify.
- --help says just '/export [file]'. No mention of .txt forcing,
no mention of path-resolution semantics.
- Claw pipelines that glob *.md won't find /export outputs.
Trace:
main.rs:5990 resolve_export_path: extension check + conditional
.txt append
main.rs:6021 run_export: fs::write direct, no path munging
main.rs:5975 default_export_filename: hardcodes .txt fallback
Content renderer is Markdown (render_session_markdown:6075)
Fix shape (~70 lines):
- unify both paths via shared export_session_to_path helper
- respect caller's extension (pick renderer by extension or
accept that content is Markdown and name accordingly)
- path-traversal policy decision: restrict to project root or
allow-with-warning
- --help: document suffix preservation + path semantics
- regression tests for extension preservation + dotdot rejection
Joins silent-flag cluster (#96-#101) on silent-rewrite axis.
New two-paths-diverge sub-cluster: #91 (permission-mode parser
disagree) + #101 (CLI vs env asymmetry) + #104 (slash vs CLI
export asymmetry) — three instances of parallel entry points
doing subtly different things.
Natural bundles: #91 + #101 + #104 (two-paths-diverge trio),
#96 + #98 + #99 + #101 + #104 (silent-rewrite-or-noop quintet).

Claw Code is the public Rust implementation of the claw CLI agent harness.
The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.
Important
Start with
USAGE.mdfor build, auth, CLI, session, and parity-harness workflows. Makeclaw doctoryour first health check after building, userust/README.mdfor crate-level details, readPARITY.mdfor the current Rust-port checkpoint, and seedocs/container.mdfor the container-first workflow.ACP / Zed status:
claw-codedoes not ship an ACP/Zed daemon entrypoint yet. Runclaw acp(orclaw --acp) for the current status instead of guessing from source layout;claw acp serveis currently a discoverability alias only, and real ACP support remains tracked separately inROADMAP.md.

Quick start
Note
[!WARNING]
cargo install claw-codeinstalls the wrong thing. Theclaw-codecrate on crates.io is a deprecated stub that placesclaw-code-deprecated.exe— notclaw. Running it only prints"claw-code has been renamed to agent-code". Do not usecargo install claw-code. Either build from source (this repo) or install the upstream binary:cargo install agent-code # upstream binary — installs 'agent.exe' (Windows) / 'agent' (Unix), NOT 'agent-code'This repo (
ultraworkers/claw-code) is build-from-source only — follow the steps below.
# 1. Clone and build
git clone https://github.com/ultraworkers/claw-code
cd claw-code/rust
cargo build --workspace
# 2. Set your API key (Anthropic API key — not a Claude subscription)
export ANTHROPIC_API_KEY="sk-ant-..."
# 3. Verify everything is wired correctly
./target/debug/claw doctor
# 4. Run a prompt
./target/debug/claw prompt "say hello"
Note
Windows (PowerShell): the binary is
claw.exe, notclaw. Use.\target\debug\claw.exeor runcargo run -- prompt "say hello"to skip the path lookup.
Windows setup
PowerShell is a supported Windows path. Use whichever shell works for you. The common onboarding issues on Windows are:
- Install Rust first — download from https://rustup.rs/ and run the installer. Close and reopen your terminal when it finishes.
- Verify Rust is on PATH:
If this fails, reopen your terminal or run the PATH setup from the Rust installer output, then retry.cargo --version - Clone and build (works in PowerShell, Git Bash, or WSL):
git clone https://github.com/ultraworkers/claw-code cd claw-code/rust cargo build --workspace - Run (PowerShell — note
.exeand backslash):$env:ANTHROPIC_API_KEY = "sk-ant-..." .\target\debug\claw.exe prompt "say hello"
Git Bash / WSL are optional alternatives, not requirements. If you prefer bash-style paths (/c/Users/you/... instead of C:\Users\you\...), Git Bash (ships with Git for Windows) works well. In Git Bash, the MINGW64 prompt is expected and normal — not a broken install.
Note
Auth: claw requires an API key (
ANTHROPIC_API_KEY,OPENAI_API_KEY, etc.) — Claude subscription login is not a supported auth path.
Run the workspace test suite:
cd rust
cargo test --workspace
