 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.

-409. **`init --output-format json` emits redundant parallel artifact schemas — `artifacts[].status` and flat `created[]`/`skipped[]`/`updated[]` arrays carry identical state, and `artifacts[].status:"skipped"` omits `skip_reason`** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `claw init --output-format json` on a fresh directory returns a JSON object with two parallel representations of the same artifact set: (1) `artifacts: [{name, status}]` — a structured per-artifact array; and (2) `created: [...]`, `skipped: [...]`, `updated: [...]` — flat string arrays partitioned by status. Both encode the same four artifact names and their outcomes with no additional information between them. On a subsequent run in an already-initialized directory, every artifact has `status:"skipped"`, but no `reason` field is present on any artifact entry — automation cannot distinguish `"already_exists"` (safe to ignore) from `"permission_denied"`, `"dry_run"`, or `"conflicting_contents"` (each requiring a different response). The `message` field also embeds `"skipped (already exists)"` prose that is absent from the structured payload. **Required fix shape:** (a) pick one canonical artifact representation — either `artifacts[{name, status, reason?, path?}]` or the flat status arrays — and deprecate the other; (b) add a `skip_reason` or `reason` field to `artifacts[]` entries with `status:"skipped"` and `status:"error"`, using an enum such as `already_exists`, `permission_denied`, `dry_run`, `conflict`, `unknown`; (c) add optional `path` (absolute) to each artifact entry so automation can act on the real on-disk location without re-joining with `project_path`; (d) add regression coverage proving `init --output-format json` on an existing directory includes machine-classifiable skip reasons for every skipped artifact and does not rely on the prose `message` field for structured state. **Why this matters:** init is the bootstrapping surface automation uses to ensure a project is claw-ready. If skip classification requires parsing human prose and the structured payload has two redundant formats, claws either over-provision re-inits or cannot distinguish safe skips from blocked writes without brittle message scraping.

+416. **`plugins list --output-format json` returns the mutation response shape with a prose `message` table instead of a structured `plugins:[]` array — `name`, `version`, `status`, `source` are embedded in `message` prose only** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `claw plugins list --output-format json` returns `{"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}`. This is the same four-key response envelope used by `plugins enable` and `plugins disable` mutation commands, not a list envelope. The `message` field contains the full rendered prose table (plugin name, version, and status as whitespace-aligned columns), but no `plugins` array with structured per-entry objects. `target` is `null` because no specific plugin was targeted. The `reload_runtime:false` field is meaningless for a read-only list operation. **This is distinct from ROADMAP #411** which covers the mutation commands' own missing `changed`/`previous_status`/`version`/`source` fields — #416 targets the list command's structural mismatch: it uses the mutation envelope entirely instead of emitting a dedicated list schema. **Required fix shape:** (a) emit a distinct `{kind:"plugin_list", plugins:[{name, version, status, source, path?, description?}], count}` envelope for the `list` action; (b) omit `action`, `reload_runtime`, and `target` from list responses (mutation-only fields); (c) the `message` field should be absent or optional and must not be the sole machine-readable inventory surface; (d) add regression coverage proving `plugins list --output-format json` populates a `plugins` array with at least `name`, `version`, and `status` fields for each installed plugin. **Why this matters:** automation that calls `plugins list --output-format json` to discover installed plugin inventory receives only a whitespace-aligned prose table in a string field, with `reload_runtime:false` and `target:null` as the only other machine-readable signals — identical noise to what a failed enable command returns.
