 450. **`prompt` emits `kind:"missing_credentials"` JSON on STDERR (not stdout), leaving stdout at 0 bytes — automation pattern `output=$(claw prompt hello --output-format json)` captures nothing on auth-absent failure; `doctor` correctly surfaces `auth.status:"warn"` with `api_key_present:false` but exposes no `prompt_ready:false` field that automation can check before invoking `prompt`** — dogfooded 2026-05-16 by Jobdori on `a35ee9a0` in response to Clawhip pinpoint nudge at `1505208225321062521`. Exact reproduction (isolated env, no creds, fresh git repo, HEAD `a35ee9a0`): `timeout 5 env -i HOME=$ISOLATED_HOME PATH=$PATH CLAW_CONFIG_HOME=$PROBE/.claw-cfg claw prompt hello --output-format json > stdout.txt 2> stderr.txt` → stdout = **0 bytes**, stderr = 195 bytes containing `{"error":"missing Anthropic credentials…","exit_code":1,"hint":null,"kind":"missing_credentials","type":"error"}`, exit code 1. Confirms Gaebal's `1505208553793781792` pinpoint that `prompt` timeout + zero bytes was the prior state — HEAD `a35ee9a0` now correctly exits 1 with `kind:"missing_credentials"` **but the envelope is still routed to stderr** (issue #447 class, same class as prior entries #422, #435). **Contrast with `doctor`:** `claw doctor --output-format json 2>/dev/null` succeeds to stdout with `checks[auth].status:"warn"`, `api_key_present:false`, `auth_token_present:false` — but the auth check has no `prompt_ready:false` field. Automation that gates on `doctor` before invoking `prompt` must re-derive readiness from `api_key_present && auth_token_present` — there is no single canonical boolean. **Three compound problems:** (a) **stdout-empty on `--output-format json` failure**: same class as #447; `prompt`'s error envelope goes to stderr, not stdout. The canonical automation idiom `if ! result=$(claw prompt "q" --output-format json); then echo "$result" | jq .kind; fi` sees `$result=""` on failure — the jq call gets nothing. All `--output-format json` error paths must route JSON to stdout per #447 contract; (b) **`doctor` missing `prompt_ready` field**: `doctor --output-format json` already knows auth is absent (`api_key_present:false`) but surfaces no derived `prompt_ready:bool` or `prompt_blocked_reason:string` field. Automation must infer readiness from `api_key_present || auth_token_present || legacy_*_present` — a 5-field OR across legacy fields that is fragile as auth mechanisms evolve. A single `prompt_ready:false` (with `prompt_blocked_reason:"auth_missing"`) inside the `auth` check would give downstream a stable contract; (c) **`claw prompt` with no auth does no preflight and fires straight at the API**: the preflight check that `doctor` runs (auth discovery) is not reused by `prompt` to emit a fast typed error before attempting the network call. Both Gaebal's pinpoint (prompt hanging silently on older HEAD) and the current behavior (prompt hitting auth gate after a brief API attempt) stem from the same root: prompt does not short-circuit at the point where `doctor` already knows auth is absent. If `doctor` can emit `kind:"doctor"` with `auth.status:"warn"` in ~20ms without a network call, `prompt` should emit `kind:"missing_credentials"` in the same window and output it to stdout. **Required fix shape:** (a) `prompt --output-format json` must write the `kind:"missing_credentials"` JSON envelope to **stdout**, not stderr — same fix as #447 for all error envelopes; (b) add `prompt_ready:bool` and `prompt_blocked_reason:string|null` to the `auth` check in `doctor --output-format json`; derive it as `api_key_present || auth_token_present || legacy_saved_oauth_present`; (c) `prompt` must run the credential preflight check (same codepath as doctor's auth check) before attempting any API call and emit `{"kind":"missing_credentials","prompt_blocked_reason":"auth_missing"}` on **stdout** with exit 1 if the check fails; (d) `--output-format json` stdout routing fix must cover: `prompt`, `session list` (cross-ref #449), `skills uninstall` (cross-ref #431), `resume` (cross-ref #435), `acp serve` (cross-ref #443) — the full `kind:"missing_credentials"` class; (e) regression test: `claw prompt hello --output-format json` with no creds writes JSON to stdout (0 bytes stderr), exits 1, `kind:"missing_credentials"`, in under 200ms (no network attempt). **Why this matters:** `prompt` is the primary consumer entry point. Auth-absent failure routing to stderr breaks every automation wrapper that captures `$(claw prompt ... --output-format json)`. The `doctor` preflight metadata gap means auth-readiness checks require parsing 5 legacy fields instead of reading one boolean. Cross-references #447 (all JSON error envelopes on stderr), #449 (session list hits auth gate), #431 (skills uninstall hits auth gate), #357 (auth gate on local ops cluster), #422 (exit-code parity).

 451. **Dogfood automation can silently run probes in the wrong repository/worktree when adjacent checkouts share similarly named binaries and stale build artifacts, so reports may mix evidence from Clawdbot/OMX with claw-code** — dogfooded 2026-05-19 from the `#clawcode-building-in-public` 12:00/12:30 UTC nudge cycle. While following a tmux-hook JSON lifecycle probe, the shell reported `/home/bellman/clawd` as the top-level worktree and executed `node dist/cli/omx.js ...` from Clawdbot/OMX artifacts instead of a claw-code checkout; a later correction found the actual claw-code repos under `/home/bellman/Workspace/claw-code-*`, including one `main` checkout hundreds of commits behind `origin/main`. The transcript therefore briefly contained plausible-looking CLI evidence from the wrong product tree before git provenance checks caught it. **Required fix shape:** (a) before dogfood probes, emit a mandatory machine-readable provenance preflight with repo root, remote URL, branch, HEAD, upstream HEAD, ahead/behind counts, binary path, and embedded build SHA when available; (b) make report templates include this provenance block before any command evidence; (c) warn or block when the requested product name does not match the remote/package/binary identity, or when the checkout is behind the target upstream by a configured threshold; (d) add regression coverage around multi-worktree/multi-product environments proving dogfood harnesses cannot silently attribute evidence from a neighboring repo or stale artifact. **Why this matters:** stale-branch confusion is not just a git annoyance; it corrupts the evidence chain. Claws can land or report fixes against the wrong codebase if the harness does not prove repo and binary identity before probing.

+452. **Validated claw-code checkouts can have no runnable local debug binary, and the failure is a raw shell `No such file or directory` instead of a typed build/provenance preflight result** — dogfooded 2026-05-19 from the `#clawcode-building-in-public` 13:00 UTC nudge after applying the provenance guard from #451. The corrected claw-code checkout was `/home/bellman/Workspace/claw-code-pr2967` with remote `https://github.com/ultraworkers/claw-code.git`, branch `docs/roadmap-workdir-provenance`, HEAD `6183d95`, upstream `origin/main` at `f8e1bb7`, and ahead/behind `1/0`. The first real probe then failed before reaching claw-code logic: `timeout --kill-after=1s 8s ./rust/target/debug/claw plugins list --output-format json` exited `127` with stderr `timeout: failed to run command './rust/target/debug/claw': No such file or directory` and empty stdout. This is distinct from stale-binary mismatch: here the selected checkout is identifiable, but there is no built binary and no canonical instruction/result telling automation whether to build, locate an installed `claw`, or stop. **Required fix shape:** (a) provide a canonical `claw dogfood preflight --output-format json` or equivalent script that checks expected binary paths, installed binary fallback, embedded build SHA, workspace HEAD, and build freshness before any product probe; (b) when the expected local binary is absent, return a typed result such as `kind:"dogfood_preflight"`, `binary_status:"missing"`, `expected_path`, `recommended_build_command`, and `can_use_installed_binary:false|true`; (c) integrate the preflight into dogfood report templates so a missing build artifact is reported as startup friction, not a raw shell 127; (d) add regression/fixture coverage for missing binary, stale binary, matching debug binary, and installed-binary fallback cases. **Why this matters:** after #451 proves the repo is right, claws still need to prove the executable exists and corresponds to that repo. A raw shell missing-file error wastes a nudge cycle and tempts operators to run whatever stale binary happens to be nearby.
