 348. **Top-level `plugins list --output-format json` returns plugin inventory only as a prose `message` string instead of structured `plugins[]` entries** — dogfooded 2026-04-29 for the 21:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `cca6f682`. Running `./rust/target/debug/claw plugins list --output-format json` repeatedly returned valid stdout JSON with `{"action":"list","kind":"plugin","message":"Plugins\n  example-bundled      v0.1.0      disabled\n  sample-hooks         v0.1.0      disabled","reload_runtime":false,"target":null}` and no stderr. The actual plugin names, versions, and enabled/disabled states are present only inside the human-formatted `message` table; there is no `plugins[]` array, no per-plugin `name`, `version`, `enabled`, `source`, `load_error`, or lifecycle/action metadata. This is distinct from #325's broad help JSON opacity and the config/MCP/agent items: the affected surface is plugin lifecycle inventory, where automation needs a structured list before enabling, disabling, updating, or uninstalling plugins. **Required fix shape:** (a) add `plugins[]` with stable per-plugin fields such as `name`, `version`, `enabled`, `source`, `configured`, `load_status`, and optional `error`; (b) keep `message` only as a human summary, not the sole inventory payload; (c) expose counts and truncation metadata if the list can be large; (d) add regression coverage proving `plugins list --output-format json` can be parsed without scraping the prose message and that disabled/enabled state survives as booleans/enums. **Why this matters:** plugin lifecycle management is a control-plane path. If the JSON inventory is just a text table, claws must scrape spacing-sensitive prose before deciding whether a plugin is installed, disabled, broken, or safe to mutate.

 349. **Top-level `plugins show <name> --output-format json` returns success-shaped JSON for an unsupported plugin action instead of a typed unsupported-action error** — dogfooded 2026-04-29 for the 21:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a2a38df9`. After rebuilding and verifying the binary provenance, repeated bounded runs of `./rust/target/debug/claw plugins show does-not-exist --output-format json` returned stdout JSON with `{"action":"show","kind":"plugin","message":"Unknown /plugins action 'show'. Use list, install, enable, disable, uninstall, or update.","reload_runtime":false,"target":"does-not-exist"}` and no stderr. The command therefore reports the requested unsupported action as the top-level `action:"show"` and exits successfully while hiding the failure class inside a human `message`; it does not provide `status:"unsupported_action"`, `code:"plugin_action_unsupported"`, or structured `supported_actions[]`. This is distinct from #348's prose-only plugin inventory schema: #348 covers `plugins list` payload shape, while this pinpoint covers unsupported plugin action classification and recovery metadata. **Required fix shape:** (a) return a typed stdout JSON error or explicit non-ok status for unsupported plugin actions, with `requested_action`, `supported_actions`, and `target` fields; (b) do not label the primary `action` as the unsupported requested verb unless a separate `status`/`code` makes the failure unambiguous; (c) keep the human message optional and avoid making it the only way to detect the unsupported action; (d) add regression coverage proving `plugins show foo --output-format json` is machine-classifiable as unsupported without scraping prose. **Why this matters:** plugin lifecycle automation follows action/status fields. If an unsupported mutation/inspection verb returns success-shaped JSON and only says "Unknown" in prose, claws can treat a failed preflight as a valid plugin show result and continue toward unsafe lifecycle actions.

 350. **Top-level `plugins enable <missing-plugin> --output-format json` hangs with zero stdout/stderr instead of returning a typed plugin-not-found or unsupported-target response** — dogfooded 2026-04-29 for the 22:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `ee44ff98`. After rebuilding and verifying the binary provenance, repeated bounded runs of `timeout 8 ./rust/target/debug/claw plugins enable does-not-exist --output-format json` exited `124` with `stdout=0` and `stderr=0`; a third sample was still stuck until killed. In the same rebuilt binary, `plugins list --output-format json` returned promptly with the known plugin inventory payload, proving the plugin top-level surface is reachable and narrowing the hang to missing-plugin lifecycle mutation. This is distinct from #348's prose-only list inventory and #349's unsupported `plugins show` success-shaped JSON: #350 covers a supported lifecycle verb (`enable`) against an absent target, where the CLI should be able to fail fast before any plugin runtime work. **Required fix shape:** (a) validate the target plugin against the discovered/configured inventory before invoking enable-side effects; (b) return bounded stdout JSON such as `kind:"plugin"`, `action:"enable"`, `status:"not_found"` or `kind:"error"`, `code:"plugin_not_found"`, `plugin`, and optional `available_plugins[]`; (c) add internal timeout/diagnostic metadata for plugin lifecycle operations so registry or hook stalls do not produce silent zero-byte hangs; (d) add regression coverage proving `plugins enable does-not-exist --output-format json` returns a typed JSON outcome within a deterministic budget and does not mutate plugin state. **Why this matters:** enable/disable/update/uninstall are destructive control-plane actions. A missing or stale plugin name must fail safely and machine-readably; otherwise claws cannot preflight plugin lifecycle operations, distinguish typo from loader deadlock, or recover without killing a hung process.

+364. **`/cost --output-format json` returns token counts only with no `cost_usd`, `currency`, or per-type cost breakdown; output is identical to `/stats` except for the `kind` field** — dogfooded 2026-04-30 by Jobdori on `c6c01bea`. Running `./rust/target/debug/claw --output-format json --resume latest /cost` returns the exact same JSON blob as `/stats` with only `"kind":"cost"` differing. Neither `cost_usd`, `currency`, `cost_by_type`, `model_pricing`, nor any monetary figure appears in the response. A claw tracking spend has no way to get dollar amounts from this command. This is distinct from the broader issue in #360 covering all three commands: this entry specifically documents the `/cost` command's missing monetary contract as a standalone gap. **Required fix shape:** (a) `/cost --output-format json` must include `cost_usd` (float), `currency` (string, e.g. `"usd"`), and optionally `cost_breakdown: {input, output, cache_read, cache_write}` in USD; (b) if pricing is unavailable for the active model, return `cost_usd: null` with `pricing_available: false`; (c) separate `/cost`'s response schema from `/stats` so they have distinct required fields; (d) add regression coverage confirming `/cost` includes a `cost_usd` field (may be null but must be present).
