 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.

-401. **`export --output-format json` response includes `messages: <int>` (a count, not an array) and `markdown: "<full prose>"` (the entire transcript as an embedded string) — `messages` type is ambiguous (count vs array?), and embedding the full markdown prose in the JSON envelope bloats the payload and mixes machine-readable metadata with human-readable content** — dogfooded 2026-04-30 by Jobdori on `e939777f`. Running `./claw --output-format json export` returns `{"file":"<path>","kind":"export","markdown":"# Conversation Export\n...","messages":1,"session_id":"..."}`. The `messages` field is an integer count (observed: `1`), not a `messages[]` array — automation cannot tell the difference between "1 message" and a future "messages[1-item-array]" without schema documentation. The `markdown` field embeds the full rendered transcript as a prose string rather than omitting it (since `file` already provides the path), making large sessions produce multi-kilobyte JSON payloads that duplicate the file contents. No `truncated`, `message_count`, `byte_count`, or `schema_version` field. **Required fix shape:** (a) rename `messages` to `message_count: u32` or expand to `messages: []` (array of structured message refs); (b) remove `markdown` from the JSON envelope or replace it with a `preview` field with truncation metadata (`preview_chars`, `truncated: bool`); (c) add `byte_count` for the exported file; (d) add regression coverage proving `export --output-format json` produces a stable, non-bloating JSON contract independent of transcript length.

+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.
