Yeachan-Heo 61fd7cfec5 Lock in Linux hook stdin BrokenPipe coverage
Latest main already contains the functional BrokenPipe tolerance in
plugins::hooks::CommandWithStdin::output_with_stdin, but the only
coverage for the original CI failure was the higher-level plugin hook
test. Add a deterministic regression that exercises the exact low-level
EPIPE path by spawning a hook child that closes stdin immediately while
the parent writes an oversized payload.

This keeps the real root cause explicit: Linux surfaced BrokenPipe from
the parent's stdin write after the hook child closed fd 0 early. Missing
execute bits were not the primary bug.

Constraint: Keep the change surgical on top of latest main
Rejected: Re-open the production code path | latest main already contains the runtime fix
Rejected: Inflate HookRunner payloads in the regression | HOOK_* env injection hit ARG_MAX before the pipe path
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep BrokenPipe coverage near CommandWithStdin so future refactors do not regress the Linux EPIPE path
Tested: cargo test -p plugins hooks::tests::collects_and_runs_hooks_from_enabled_plugins -- --exact (10x)
Tested: cargo test -p plugins hooks::tests::output_with_stdin_tolerates_broken_pipe_when_child_closes_stdin_early -- --exact (10x)
Tested: cargo test --workspace

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.md for build, auth, CLI, session, and parity-harness workflows. Make claw doctor your first health check after building, use rust/README.md for crate-level details, read PARITY.md for the current Rust-port checkpoint, and see docs/container.md for the container-first workflow.

Current repository shape

  • rust/ — canonical Rust workspace and the claw CLI binary
  • USAGE.md — task-oriented usage guide for the current product surface
  • PARITY.md — Rust-port parity status and migration notes
  • ROADMAP.md — active roadmap and cleanup backlog
  • PHILOSOPHY.md — project intent and system-design framing
  • src/ + tests/ — companion Python/reference workspace and audit helpers; not the primary runtime surface

Quick start

cd rust
cargo build --workspace
./target/debug/claw --help
./target/debug/claw prompt "summarize this repository"

Authenticate with either an API key or the built-in OAuth flow:

export ANTHROPIC_API_KEY="sk-ant-..."
# or
cd rust
./target/debug/claw login

Run the workspace test suite:

cd rust
cargo test --workspace

Ecosystem

Claw Code is built in the open alongside the broader UltraWorkers toolchain:
