 353. **Top-level `plugins uninstall <missing-plugin> --output-format json` sends a generic JSON error envelope to stderr only, leaving stdout empty** — dogfooded 2026-04-29 for the 23:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `6f92e54d`. After rebuilding and verifying the binary provenance, repeated bounded runs of `timeout 8 ./rust/target/debug/claw plugins uninstall does-not-exist --output-format json` exited `1` with `stdout=0` and `stderr=97`; stderr contained JSON (`{"error":"plugin `does-not-exist` is not installed","hint":null,"kind":"unknown","type":"error"}`), but stdout was empty. In the same rebuilt binary, `plugins list --output-format json` returned stdout JSON promptly with the known plugin inventory payload. This is distinct from #350's missing-target `plugins enable` zero-byte timeout and parallel to #351/#352 for disable/update: uninstall fails fast, but the JSON-mode error lives on stderr only and uses generic `kind:"unknown"`/`type:"error"` instead of a plugin-specific not-found contract. **Required fix shape:** (a) define and consistently document stdout/stderr placement for JSON-mode lifecycle errors; (b) return a plugin-specific typed error with `kind:"plugin"` or `domain:"plugin"`, `action:"uninstall"`, `status:"not_found"` or `code:"plugin_not_found"`, `plugin`, and optional `available_plugins[]`; (c) share missing-target error-envelope behavior across disable/update/uninstall and reconcile it with enable's timeout path; (d) add regression coverage proving `plugins uninstall does-not-exist --output-format json` produces a typed plugin-not-found JSON contract on the documented stream. **Why this matters:** uninstall is the most destructive plugin lifecycle action. A stale plugin name should produce a predictable, domain-specific not-found result before cleanup hooks or loader work, not require callers to special-case stderr-only generic error envelopes after explicitly requesting JSON. Source: gaebal-gajae dogfood follow-up for the 23:30 nudge on rebuilt `./rust/target/debug/claw` `6f92e54d`; invalid hang PR #2897 was closed after repeated bounded repros returned exit 1 with JSON on stderr.
 354. **Top-level `memory list` and `memory help` with `--output-format json` hang with zero stdout/stderr instead of returning bounded memory inventory/help or a typed unavailable response** — dogfooded 2026-04-30 for the 00:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `19947545`. After rebuilding and verifying the binary provenance, bounded runs of `timeout 8 ./rust/target/debug/claw memory list --output-format json` produced `stdout=0` and `stderr=0`; the first sample exited `124` and the second sample was still stuck until killed. A follow-up sanity check of `timeout 8 ./rust/target/debug/claw memory help --output-format json` also exited `124` with `stdout=0` and `stderr=0`, so the issue is broader than list inventory: even the memory help path can hang silently in JSON mode. This is distinct from prior plugin lifecycle stream/status items: the affected surface is memory command introspection, where claws need safe local help/inventory before reading or mutating memory. **Required fix shape:** (a) make `memory help` and `memory list --output-format json` return bounded local JSON without requiring external/authenticated backing store availability; (b) return stdout JSON with `kind:"memory"`, `action:"help"|"list"`, `status`, usage or `entries[]`, source/provenance, counts, and truncation metadata; (c) if credentials/config/backing store are missing or slow, return a typed JSON unavailable/config/timeout error instead of hanging; (d) add regression coverage proving both `memory help --output-format json` and `memory list --output-format json` return machine-readable outcomes within a deterministic budget. **Why this matters:** memory is a core clawability surface. If even help/list can hang silently with no bytes, agents cannot tell whether memory is empty, unavailable, remote-auth blocked, or deadlocked, and any higher-level recall/debug flow stalls at the first introspection step.

 355. **Top-level `session list` and `session help` with `--output-format json` hang with zero stdout/stderr instead of returning bounded session inventory/help or a typed unavailable response** — dogfooded 2026-04-30 for the 00:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `8e24f304`. After rebuilding and verifying the binary provenance, repeated bounded runs of `timeout 8 ./rust/target/debug/claw session list --output-format json` exited `124` with `stdout=0` and `stderr=0`. A follow-up bounded `session help --output-format json` probe also produced no stdout/stderr before it had to be killed, so the issue is broader than inventory: even the session help path can silently hang in JSON mode. This is distinct from #354's memory help/list hang: the affected surface is session command introspection, where claws need a safe local way to enumerate resumable sessions or at least read usage before deciding whether to resume, inspect, or clean them up. **Required fix shape:** (a) make `session help` and `session list --output-format json` return bounded local JSON without waiting indefinitely on remote API/auth/session-store availability; (b) return stdout JSON with `kind:"session"`, `action:"help"|"list"`, `status`, usage or `sessions[]`, source/provenance, counts, and truncation metadata, or typed `status:"unavailable"`/`code` when backing state cannot be reached; (c) add explicit timeout diagnostics if a remote/authenticated session source is consulted; (d) add regression coverage proving both `session help --output-format json` and `session list --output-format json` return machine-readable outcomes within a deterministic budget. **Why this matters:** session inventory/help is a core recovery/control-plane path. If even help/list can hang silently with no bytes, claws cannot distinguish no sessions, missing credentials, remote API stall, corrupted local store, or dispatch deadlock, and resume/cleanup automation blocks before it can choose a safe next action.

+356. **Top-level `status --help --output-format json` hangs with zero stdout/stderr instead of returning bounded command help JSON** — dogfooded 2026-04-30 for the 01:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `74338dc6`. After rebuilding and verifying the binary provenance, repeated bounded runs of `timeout 8 ./rust/target/debug/claw status --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; the hang is specific to the status help surface. This is distinct from #354/#355 memory/session JSON help/list hangs: the affected surface is the status command's help path, which should be local/static and should never wait on workspace inspection, credentials, or runtime status probes. **Required fix shape:** (a) make `status --help --output-format json` return static/bounded stdout JSON with `kind:"help"` or `kind:"status"`, `action:"help"`, usage, options, examples, and supported output formats; (b) ensure help rendering does not initialize slow status/workspace/runtime probes; (c) return a typed JSON timeout/unavailable error if any dynamic provider is accidentally consulted; (d) add regression coverage proving status help in JSON mode returns within a deterministic budget and emits no zero-byte hang. **Why this matters:** help must be the safe fallback when command behavior is unclear. If even `status --help --output-format json` can hang silently, claws cannot discover status semantics or recover from status-command failures without killing the process.
