 358. **Top-level `cost --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 02:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `d95b230c`. After rebuilding and verifying the binary provenance, repeated bounded runs of `timeout 8 ./rust/target/debug/claw cost --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 the JSON output path are reachable; the hang is specific to the cost help path, though other help surfaces have separate known JSON contract issues (#356/#357). **Required fix shape:** (a) make `cost --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"cost"`, `action:"help"`, usage, options, examples, supported output formats, and related slash/direct commands; (b) ensure help rendering does not initialize slow cost/session/accounting providers; (c) if any dynamic provider is accidentally consulted, return a typed JSON timeout/unavailable error instead of hanging; (d) add regression coverage proving cost help in JSON mode returns within a deterministic budget. **Why this matters:** cost/tokens surfaces are commonly consumed by automation for budgeting. If even cost help can hang silently, claws cannot discover cost command semantics or present safe budget diagnostics before running potentially slow accounting paths.

 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.

+411. **`plugins enable/disable --output-format json` always emits `reload_runtime:true` regardless of whether state actually changed, and omits `previous_status`, `changed`, `version`, and `source` fields — automation cannot tell if a reload is necessary or if the mutation was a no-op** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `claw plugins enable example-bundled --output-format json` on an already-enabled plugin returns `{"action":"enable","kind":"plugin","message":"…","reload_runtime":true,"target":"example-bundled"}` — `reload_runtime:true` every time, even on a no-op re-enable. The same applies to idempotent `disable`. Structured fields present: `action`, `kind`, `message`, `reload_runtime`, `target`. Structured fields absent: `previous_status`, `status`, `changed`, `version`, `source`. The actual plugin name, version, and new status are embedded only in the prose `message` field (`"Result  enabled example-bundled@bundled\n  Name  example-bundled\n  Version  0.1.0\n  Status  enabled"`), requiring callers to scrape column-aligned text to extract the post-mutation state. A no-op mutation emitting `reload_runtime:true` forces orchestration to trigger an expensive runtime reload even when no config change occurred. **Required fix shape:** (a) add `changed:bool` so callers can skip runtime reload when `changed:false`; (b) add `previous_status` and `status` fields (enums: `enabled`/`disabled`) so pre/post state is machine-readable without parsing `message`; (c) add `version` and `source` fields at the mutation response level, consistent with `plugins list` entry shape; (d) emit `reload_runtime:false` when `changed:false`; (e) add regression coverage proving idempotent enable/disable sets `changed:false` and `reload_runtime:false`. **Why this matters:** plugin lifecycle is a hot path for automation that conditionally enables plugins before running sessions. If every enable emits `reload_runtime:true` and no `changed` field exists, orchestration must reload unconditionally or maintain external state — both brittle patterns.
