 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.

-400. **`status --output-format json` `workspace` has `session: "live-repl"` (non-null string) simultaneously with `session_id: null`, and `session_lifecycle.kind: "saved_only"` with `abandoned: true` — the session name and session ID are reported in contradictory states, and the lifecycle fields provide no `session_path` or `resume_command` to recover the abandoned session** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `./claw --output-format json status` outside an active session returns `workspace.session: "live-repl"`, `workspace.session_id: null`, `workspace.session_lifecycle: {"abandoned":true,"kind":"saved_only","pane_command":null,"pane_id":null,"pane_path":null,"workspace_dirty":true}`. The `session` field implies an active named session, but `session_id: null` and `abandoned: true` indicate no active session; automation cannot tell from these fields alone whether a session is resumable, what file to pass to `--resume`, or whether the session name `"live-repl"` is a stable identifier. The `pane_command`/`pane_id`/`pane_path` fields are all null for abandoned sessions, providing no actionable recovery path. **Required fix shape:** (a) make `session` and `session_id` consistent — both null when no active session, both populated when active; (b) add `session_path` (path to the `.jsonl` file) and `resume_command` (full `claw --resume <path>` incantation) to the lifecycle fields when `kind:"saved_only"` so automation can recover without filesystem scraping; (c) add `workspace_dirty` explanation field (e.g., `dirty_reason: "uncommitted_changes"`); (d) add regression coverage proving the session name/ID pair is always consistent.

+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.
