Dogfooded 2026-04-18 on main HEAD 8b25daf from /tmp/cdJJ. Test matrix: /session list → works (structured JSON) /session switch s → 'unsupported resumed slash command' /session fork foo → 'unsupported resumed slash command' /session delete s → 'unsupported resumed slash command' /session delete s --force → 'unsupported resumed slash command' claw session delete s → Prompt fallthrough (#108), 'missing credentials' from LLM error path Help documents ALL session verbs as one unified capability: /session [list|switch <session-id>|fork [branch-name]|delete <session-id> [--force]] Summary: 'List, switch, fork, or delete managed local sessions' Implementation: main.rs:10618 parser builds SlashCommand::Session{action, target} for every subverb. All parse successfully. main.rs:2908-2925 dedicated /session list handler. Only one. main.rs:2936-2940+ catch-all: SlashCommand::Session {..} | SlashCommand::Plugins {..} | ... => Err(format_unsupported_resumed_slash_command(...)) main.rs:3963 SlashCommand::Session IS handled in LiveCli REPL path — switch/fork/delete implemented for interactive mode. runtime/session_control.rs:131+ SessionStore::resolve_reference, delete_managed_session, fork_managed_session all exist. grep 'claw session\b' main.rs → zero matches. No CLI subcommand. Gap: backing code exists, parser understands verbs, REPL handler wired — ONLY the --resume dispatch path lacks switch/fork/delete plumbing, and there's no claw session CLI subcommand as programmatic alternative. A claw orchestrating session lifecycle at scale has three options: a) start interactive REPL (impossible without TTY) b) manual .claw/sessions/ rm/cp (bypasses bookkeeping, breaks with #112's proposed locking) c) stick to /session list + /clear, accept missing verbs Fix shape (~130 lines): - /session switch <id> in run_resume_command (~25 lines) - /session fork [branch] in run_resume_command (~30 lines) - /session delete <id> [--force] in run_resume_command (~30), --force required without TTY - claw session <verb> CLI subcommand (~40) - --help: annotate which session verbs are resume-safe vs REPL-only - regression tests per verb x (CLI / slash-via-resume) Joins Unplumbed-subsystem (#78, #96, #100, #102, #103, #107, #109, #111) as 9th declared-but-not-delivered surface. Joins Session- handling (#93, #112) as 3rd member. Cross-cluster with Silent- flag on help-vs-impl mismatch. Natural bundles: #93 + #112 + #113 — session-handling triangle (semantic / concurrency / management API) #78 + #111 + #113 — declared-but-not-delivered triangle with three flavors: #78 fails-noisy (CLI variant → Prompt fallthrough) #111 fails-quiet (slash → wrong handler) #113 no-handler-at-all (slash → unsupported-resumed) Filed in response to Clawhip pinpoint nudge 1494887723818029156 in #clawcode-building-in-public.
Claw Code

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
