 380. **Top-level `tokens --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 02:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `d95b230c`. After verifying #358 covered `cost --help`, a fresh adjacent probe on the token-budget surface showed the same silent failure class: repeated bounded runs of `timeout 8 ./rust/target/debug/claw tokens --help --output-format json` exited `124` with `stdout=0` and `stderr=0`. In the same rebuilt binary, `version --output-format json` returned promptly with version/build metadata, proving the binary itself and JSON output path are reachable. This is distinct from #358's cost help hang: the affected surface is the sibling `tokens` command help, which agents use before estimating prompt/session token budgets. **Required fix shape:** (a) make `tokens --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"tokens"`, `action:"help"`, usage, options, examples, supported output formats, and related slash/direct commands; (b) ensure help rendering does not initialize slow token accounting, session, or provider state; (c) if any dynamic provider is consulted, return a typed JSON timeout/unavailable error instead of hanging; (d) add regression coverage proving tokens help in JSON mode returns within a deterministic budget. **Why this matters:** token budgeting is a preflight clawability surface. If help hangs silently, automation cannot safely discover how to inspect or constrain token usage before running expensive prompts, and budget-aware wrappers stall at the discovery step.

 381. **Top-level `cache --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 03:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `d95b230c`. After #358 and #380 landed for the cost/tokens preflight help hangs, a fresh adjacent probe on the cache-control surface showed the same silent failure class: repeated bounded runs of `timeout --kill-after=1s 8s ./rust/target/debug/claw cache --help --output-format json` exited `124` with `stdout=0` and `stderr=0`. In the same rebuilt binary, `version --output-format json` returned promptly with version/build metadata, proving the binary itself and JSON output path are reachable. This is distinct from the separate `/cache` slash-command envelope mismatch class: the affected surface here is top-level `cache` command help, where agents need bounded local discovery before deciding whether to inspect, clear, or summarize cache state. **Required fix shape:** (a) make `cache --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"cache"`, `action:"help"`, usage, options, examples, supported output formats, and related slash/direct commands; (b) ensure help rendering does not initialize slow cache/session/provider state; (c) if any dynamic provider is consulted, return a typed JSON timeout/unavailable error instead of hanging; (d) add regression coverage proving cache help in JSON mode returns within a deterministic budget. **Why this matters:** cache inspection and cleanup are recovery/control-plane operations. If cache help hangs silently, claws cannot safely discover cache semantics before attempting cleanup, and automation stalls before it can choose a non-destructive cache action.

-410. **`agents list`, `skills list`, and `mcp list` use three different count-field names and divergent envelope schemas despite being sibling list commands** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running all three list commands with `--output-format json` reveals incompatible envelope shapes: `agents list` emits `count:int` at the top level plus `summary:{active,shadowed,total}` and `working_directory`; `skills list` emits no top-level `count`, only `summary:{active,shadowed,total}`, and omits `working_directory`; `mcp list` uses a different count-field name `configured_servers:int`, has no `count`, no `summary`, and instead adds `status:"ok"` and `config_load_error:null` fields absent from the other two. The three sibling commands cannot be polymorphically consumed with the same count-extraction logic, requiring per-command special-casing at the cardinality check level. **Required fix shape:** (a) define one canonical top-level count field name (`count`, `total`, or `item_count`) and use it across `agents`, `skills`, and `mcp` list envelopes; (b) define one canonical `summary` object shape with at minimum `active`, `total`, and optionally `shadowed` and include it on all three; (c) expose `working_directory` consistently on all list commands or omit it from all; (d) add regression coverage proving the three list envelopes share the same count-field name and summary shape before each release. **Why this matters:** orchestration lanes that inventory agents, skills, and servers before delegation need one count-extraction pattern. Three different field names force per-command special-casing of the most basic cardinality check. Source: Jobdori live dogfood, `e939777f`, 2026-04-30.
+391. **`version --output-format json` includes a `message` field containing human-readable prose (`"Claw Code\n  Version  0.1.0\n  Git SHA  ..."`) in addition to the structured fields `version`, `git_sha`, `target`; no `action` field; no `build_date`, `platform`, or `rustc_version` structured fields — the prose is embedded inside the JSON envelope instead of being derivable from the structured fields** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `./claw --output-format json version` returns `{"git_sha":"5eb1d7d8","kind":"version","message":"Claw Code\n  Version  0.1.0\n  Git SHA  5eb1d7d8\n  Target  aarch64-apple-darwin\n  Build date  2026-04-30","target":"aarch64-apple-darwin","version":"0.1.0"}`. The `message` field duplicates structured data as prose, preventing automation from using the JSON without also parsing the prose for any field not promoted to a top-level key (e.g., `build_date`). No `action` field present (compare `agents/mcp` which include `action:"list"`). No `platform`, `rustc_version`, or `build_timestamp_ms` structured fields. **Required fix shape:** (a) remove or deprecate `message` prose field from `--output-format json` output; (b) add structured `build_date` (ISO-8601), `platform`, and `rustc_version` fields; (c) add `action:"version"` for envelope consistency; (d) add regression coverage proving the JSON response contains no prose-only fields.
