 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.
 
-358. **`/history --output-format json` entries contain only `text` and `timestamp_ms` fields; `role` is absent, making user vs assistant turns indistinguishable programmatically; no `--limit`/`--offset` pagination** — dogfooded 2026-04-30 by Jobdori on `c6c01bea`. Running `./rust/target/debug/claw --output-format json --resume latest /history` returns a `history[]` array where each entry has `text` and `timestamp_ms` only. There is no `role` field (`user`/`assistant`/`tool`), no `message_id`, no `turn_index`, and no indication of which side of the conversation produced each entry. An orchestrator that needs to extract only user prompts, or only assistant responses, cannot do so without heuristics (e.g. trying to detect prompt vs response by content). Additionally, `/history` returns all entries with no pagination controls: no `--limit`, no `--offset`, no `total_count`, no `has_more` flag. Long sessions will return unbounded output with no way to request a tail window. **Required fix shape:** (a) add `role` field to each history entry with values matching the message originator (e.g. `"user"`, `"assistant"`, `"tool_result"`); (b) add optional `--limit N` and `--offset N` flags to `/history` for pagination; (c) include `total` and `returned` counts in the response envelope; (d) add regression coverage confirming each history entry contains a non-null `role` field and that `--limit`/`--offset` return the correct slice.

+350. **`/plugins enable <nonexistent-plugin> --output-format json` times out and produces 0 bytes; hangs silently for 8+ seconds** — dogfooded 2026-04-30 by gaebal-gajae on `ee44ff98`. Running `./rust/target/debug/claw --output-format json --resume latest /plugins enable does-not-exist` with a plugin name that does not exist in the available plugins list hangs for approximately 8 seconds on repeated samples and returns 0 bytes on stdout and stderr, with no error envelope, no timeout exception, and no graceful degradation. A third sample remain stuck, suggesting a potential deadlock or resource exhaustion. The command should either: (a) return immediately with `{"kind":"error","code":"plugin_not_found","plugin_name":"does-not-exist","available_plugins":[...]}` on stdout, or (b) return a timeout error if the hang is a bug in plugin lookup. The silent 8-second hang without output breaks orchestration timeout windows (typical CI/RPC timeouts are 5-30 seconds) and provides no diagnostic information. **Required fix shape:** (a) add pre-flight plugin validation before any async operations, so unknown plugin names fail fast with a structured error; (b) if plugin lookup requires I/O, wrap with a timeout (suggested: 1 second) and emit a typed error on timeout; (c) ensure both success and error paths emit JSON when `--output-format json` is set; (d) add regression coverage confirming `/plugins enable <nonexistent>` returns within 1 second with a structured error.
