 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).

+685. **`version --help --output-format json` returns only `{kind, command, topic, message}` and does not expose the provenance fields its actual `version --output-format json` command emits (`version`, `git_sha`, `target`, `build_date`) as structured `output_fields` / schema metadata, forcing dogfooders and wrappers to scrape prose before knowing which build-identity fields are available** — dogfooded 2026-05-24 for the 22:00 Clawhip nudge at message `1508228126088626216`, reproduced on a freshly rebuilt current `origin/main` binary (`git_sha f8e1bb726`) from `/tmp/cc-probe-main-2130`. This was checked after correcting an argv-loop mistake and verifying `claw version --output-format json | jq -r .git_sha` matched the intended source revision.
+
+    Reproduction:
+
+    ```bash
+    $ env -i HOME=/tmp/iso40/home PATH=/usr/bin:/bin TERM=dumb \
+        claw version --help --output-format json
+    {
+      "command": "version",
+      "kind": "help",
+      "message": "Version\n  Usage            claw version [--output-format <format>]\n  Aliases          claw --version · claw -V\n  Purpose          print the claw CLI version and build metadata\n  Formats          text (default), json\n  Related          claw doctor (full build/auth/config diagnostic)",
+      "topic": "version"
+    }
+    ```
+
+    The command returns valid JSON, but all actionable contract details are embedded in prose. There is no structured `usage`, `aliases`, `purpose`, `formats`, `related`, `output_fields`, `provenance_fields`, `local_only`, or `requires_credentials:false` field.
+
+    Contrast with the real command on the same binary:
+
+    ```bash
+    $ claw version --output-format json
+    {
+      "kind": "version",
+      "version": "0.1.0",
+      "git_sha": "f8e1bb726",
+      "target": "x86_64-unknown-linux-gnu",
+      "build_date": "2026-05-24",
+      "message": "Claw Code\n  Version ..."
+    }
+    ```
+
+    **Why distinct from existing items:** #325 covers top-level `help --output-format json` being prose wrapped in JSON. #356/#357/#683 covered status/doctor/sandbox help-format gaps; on current main these now return parseable command-help JSON, but still largely prose-only. #684 covers `init` specifically because it is side-effectful and lacks structured write/idempotency metadata. #685 is version-specific: `version` is the build-provenance surface dogfooders use to prove whether a finding is from current code or a stale debug binary (see #324 stale-binary provenance). Its help JSON should say, machine-readably, which provenance fields exist.
+
+    **Why this matters:** Build identity is the first trust check for every dogfood report. A wrapper should be able to discover from help that `version --output-format json` includes `git_sha`, `target`, `build_date`, and `version`, and that it is local-only / credential-free. Today it must either scrape the aligned `message` string or blindly invoke `version` and reverse-engineer the schema. That weakens exactly the stale-binary guard used to avoid false ROADMAP entries.
+
+    **Required fix shape:** (a) Extend `version --help --output-format json` with structured fields such as `usage:"claw version [--output-format <format>]"`, `aliases:["claw --version","claw -V"]`, `purpose:"print build metadata"`, `formats:["text","json"]`, `output_fields:["kind","version","git_sha","target","build_date","message"]`, `provenance_fields:["git_sha","target","build_date"]`, `local_only:true`, `requires_credentials:false`, `mutates_workspace:false`, and `related:["claw doctor"]`. (b) Keep `message` as human summary only. (c) Add regression coverage proving `claw version --help --output-format json | jq '.output_fields'` includes `git_sha`, `target`, and `build_date`, and that `requires_credentials` is false. (d) Consider sharing this command-help schema pattern with status/doctor/sandbox/init/acp, but keep `version` covered explicitly because stale-binary checks depend on it. **Acceptance check:** `claw version --help --output-format json | jq -e '.command=="version" and .local_only==true and .requires_credentials==false and ([.output_fields[]] | index("git_sha") and index("target") and index("build_date"))'` should pass; currently `.local_only`, `.requires_credentials`, and `.output_fields` are absent.
