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 Not-tested: GitHub Actions rerun on the PR branch

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.
