 344. **Resume-safe `/config help --output-format json` is treated as an unsupported config section instead of a structured config-section discovery surface** — dogfooded 2026-04-29 for the 18:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a510f734`. Running `./rust/target/debug/claw --resume latest /config help --output-format json` wrote no stdout bytes and emitted stderr JSON: `{"command":"/config help","error":"Unsupported /config section 'help'. Use env, hooks, model, or plugins.\n  Usage            /config [env|hooks|model|plugins]\n\n/config\n  Summary          Inspect Claude config files or merged sections\n  Usage            /config [env|hooks|model|plugins]\n  Category         Config\n  Resume           Supported with --resume SESSION.jsonl","type":"error"}`. The same shape appears for natural discovery forms such as `/config list` and `/config show`, while bare `/config --output-format json` succeeds and returns config-file data. The config surface is therefore resume-supported, but its section discovery/help path is only available as a human-formatted error string on stderr, with no structured `sections[]`, no `help` alias, and no typed `unsupported_section` metadata. This is distinct from #342's missing slash-command index and #343's dead-end suggestion: the pinpoint is a command-specific subcommand/section discovery contract for an otherwise working resume-safe command. **Required fix shape:** (a) make `/config help` or `/config sections` resume-safe and return stdout JSON containing supported sections such as `env`, `hooks`, `model`, and `plugins`; (b) for unsupported config sections, emit a typed JSON envelope with `kind:"error"` or equivalent plus `code:"unsupported_config_section"`, `section`, and structured `supported_sections[]`; (c) keep human usage text optional, not the only machine-readable recovery path; (d) add regression coverage proving `/config help --output-format json` or its canonical replacement exposes structured section metadata and that `/config list`/`show` errors include structured supported-section guidance. **Why this matters:** config inspection is a control-plane surface. Claws should not have to intentionally trigger an error and scrape prose to learn which config sections can be inspected under `--resume`; section discovery needs the same machine-readable contract as the config payload itself.

 345. **Resume-safe `/config env|hooks|model|plugins --output-format json` accepts different section names but returns the same generic config-file summary for every section** — dogfooded 2026-04-29 for the 19:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a510f734`. Running `./rust/target/debug/claw --resume latest /config env --output-format json`, `/config hooks`, `/config model`, and `/config plugins` all wrote stdout JSON successfully and no stderr, but each response had the same top-level shape and values: `kind:"config"`, `cwd`, `files[]`, `loaded_files:1`, and `merged_keys:1`. None of the outputs included the requested `section`, section-specific keys, hook/model/plugin/env data, `section_missing`, `section_empty`, or truncation metadata; the `env`, `hooks`, `model`, and `plugins` arguments appear to be accepted while producing an indistinguishable generic config summary. This is distinct from #344's missing config-section discovery/help path: the pinpoint here is that the advertised section-specific entrypoints do not produce section-specific machine-readable payloads once invoked. **Required fix shape:** (a) include a `section` field in `/config <section> --output-format json` responses; (b) return section-specific structured payloads for `env`, `hooks`, `model`, and `plugins`, with explicit empty/missing states when applicable; (c) preserve the config-file provenance summary separately from the requested section content so callers can tell what was inspected; (d) add regression coverage proving the four supported sections produce distinguishable JSON contracts and do not silently collapse to the bare `/config` summary. **Why this matters:** config inspection is used to diagnose model, hook, plugin, and env lifecycle issues. If every supported section returns the same generic file list, claws cannot tell whether a section is empty, unsupported, redacted, or simply ignored, and config troubleshooting remains prose/error archaeology instead of structured state inspection.

 346. **Top-level `agents show <name> --output-format json` accepts a natural agent-detail request but falls back to generic help JSON instead of returning the selected agent or a typed unsupported-detail error** — dogfooded 2026-04-29 for the 20:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `c6c01bea`. Running `./rust/target/debug/claw agents list --output-format json` returned a valid stdout JSON inventory with `kind:"agents"`, `action:"list"`, and an `agents[]` entry named `analyst`. Immediately running `./rust/target/debug/claw agents show analyst --output-format json` returned success on stdout but did not return the `analyst` detail object; instead it returned generic help-shaped JSON: `{"action":"help","kind":"agents","unexpected":"show analyst","usage":{"direct_cli":"claw agents [list|help]","slash_command":"/agents [list|help]",...}}`. Both stderr streams were empty. The command therefore accepts a natural detail-inspection spelling, recognizes it only as `unexpected`, and hides the absence of an agent-detail surface behind a successful help fallback rather than a typed `unsupported_agents_action` / `agent_detail_unavailable` error. This is distinct from #328 and #329: those cover source/provenance mismatch and slash `/agents` inventory flattening, while this pinpoint is the missing top-level agent detail/inspection contract after inventory discovery succeeds. **Required fix shape:** (a) either implement `agents show <name> --output-format json` returning the selected agent's structured fields and provenance, or return a non-success typed JSON error with `code:"unsupported_agents_action"`, `requested_action:"show"`, and `supported_actions:["list","help"]`; (b) include `agent_name` and whether the name exists in the current inventory when rejecting detail inspection; (c) avoid `action:"help"` success envelopes for unsupported subcommands because they make failed detail inspection look like intentional help output; (d) add regression coverage proving `agents show analyst --output-format json` does not silently collapse to generic help when `analyst` exists in `agents list`. **Why this matters:** claws discover agents first, then need to inspect a chosen agent before delegation. If the natural detail command returns successful generic help instead of a selected-agent payload or typed unsupported-action error, automation cannot distinguish typo, unsupported detail view, missing agent, or successful help request without comparing unrelated inventory output. Source: gaebal-gajae dogfood follow-up for the 20:00 nudge on rebuilt `./rust/target/debug/claw` `c6c01bea`; earlier false hang hypotheses for `mcp help` and `agents list` were closed after bounded repros succeeded.
+347. **Top-level `mcp show <missing-server> --output-format json` reports a missing server as `status:"ok"` instead of a typed not-found/error status** — dogfooded 2026-04-29 for the 20:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `ee41b266`. After rebuilding and verifying the binary provenance, running `./rust/target/debug/claw mcp show does-not-exist --output-format json` returned stdout JSON with `{"action":"show","config_load_error":null,"found":false,"kind":"mcp","message":"server `does-not-exist` is not configured","server_name":"does-not-exist","status":"ok"}` and no stderr. `found:false` is useful, but pairing it with `status:"ok"` makes the command-level outcome ambiguous: a missing requested server is not an OK inspection result for automation that needs to distinguish successful detail retrieval from a not-found lookup. This is distinct from #327's MCP source-list mismatch and the invalid #2874/#2879/#2880 hang/nondeterminism hypotheses that were closed after bounded repros. **Required fix shape:** (a) return a typed not-found status such as `status:"not_found"` or `kind:"error"` plus `code:"mcp_server_not_found"` while preserving `server_name` and optional `available_servers[]`; (b) document whether `found:false` objects are considered success or error and keep that convention consistent across text and JSON modes; (c) ensure process exit semantics match the JSON status contract or expose a separate `exit_ok`/`lookup_status` field; (d) add regression coverage proving missing-server lookup is distinguishable from successful server detail retrieval without parsing the human `message`. **Why this matters:** MCP inspection is a control-plane diagnostic. If a missing server returns `status:"ok"`, claws can silently treat a failed lookup as healthy MCP state unless they special-case `found:false`, which defeats the purpose of a clear machine-readable status field.

+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. Source: gaebal-gajae dogfood follow-up for the 21:30 nudge on rebuilt `./rust/target/debug/claw` `a2a38df9`; invalid hang PR #2885 was closed after repeated bounded repros returned stdout JSON.
+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).
