 699. **`bootstrap-plan` and `dump-manifests` JSON/help probes fall through to prompt/auth instead of local command dispatch unless global flags are positioned just so; with normal subcommand-style argv they either hang behind the spinner or return `missing_credentials`, making local startup/manifest introspection non-local** — dogfooded 2026-05-25 on `11a6e081a` after the ROADMAP #458 envelope sweep. Reproduction with the freshly rebuilt debug binary: `./rust/target/debug/claw bootstrap-plan --output-format json </dev/null` times out after 10s with spinner bytes on stdout and only a config deprecation warning on stderr in the normal home env; in an isolated env without credentials it exits 1 as `missing_credentials` instead of returning the local bootstrap phase JSON. `./rust/target/debug/claw dump-manifests --output-format json </dev/null` behaves the same. The help forms `bootstrap-plan --help --output-format json` and `dump-manifests --help --output-format json` also time out behind the spinner. This is distinct from #690/#692, which assumed these help paths were intercepted and only lacked schema depth; current dogfood shows an even lower-level routing/argv-order gap on the rebuilt `11a6e081a` binary. **Why it matters:** `bootstrap-plan` and `dump-manifests` are supposed to be credential-free local introspection/preflight commands. If the parser treats `--output-format json` after the subcommand as prompt text or routes into the provider/auth path, claws cannot safely probe startup phases or manifest availability without API credentials and timeout guards. **Required fix shape:** (a) make subcommand-local `--output-format json` and `--help --output-format json` dispatch before prompt/auth for `bootstrap-plan` and `dump-manifests`; (b) guarantee these commands are local-only and do not require provider credentials; (c) add regression tests for both argv orders if global flags are supported after subcommands, or emit a fast typed `cli_parse` error with `status:"error"` and no spinner if not supported; (d) acceptance: `env -i HOME=/tmp/empty PATH=/usr/bin:/bin TERM=dumb ./rust/target/debug/claw bootstrap-plan --output-format json </dev/null | jq -e '.kind=="bootstrap-plan" and (.phases|length>0)'` and the analogous dump-manifests/help probes must return within 1s without credentials.

 700. **`claw help --output-format json` emits `{"kind":"help","message":"<prose>"}` with no `status` field, and `claw sessions` (via `/sessions list` slash command) emits `{"kind":"session_list",...}` — both are envelope shape inconsistencies relative to the now-complete #458 sweep** — dogfooded 2026-05-25 on `eb7c14c4`. (1) `help` JSON: all 12 probed surfaces now have `status ∈ {ok,warn,error,unsupported}` after the #458 sweep; `help` is the one remaining surface that emits JSON but lacks `status`. The envelope has only `kind:"help"` and `message:"<prose blob>"` — no machine-readable status, no structured sections array (per #325/#686/#687/#688). (2) `session_list` kind: `claw sessions` and the `/sessions list` slash command emit `"kind":"session_list"` — all other surfaces use the subcommand name as the kind token (`kind:"skills"`, `kind:"agents"`, `kind:"mcp"` etc). `session_list` is a verb+noun compound that breaks the convention and makes kind-based routing require a special case. **Required fix shape:** (a) add `"status": "ok"` to all `help` JSON emission sites (`print_help` at line ~7120 and ~7167, plus inline REPL help at ~3924 in `main.rs`); (b) rename `"kind":"session_list"` to `"kind":"sessions"` at the two emission sites (lines ~3912, ~6385) and update any test assertions; keep a `"action":"list"` field for the action discriminant. Both are 1–3 line changes. **Why this matters:** the #458 acceptance check `for c in … ; do claw $c --output-format json | jq -e '.status | IN(…)' || echo FAIL; done` still FAILs for `help`; `session_list` kind breaks any kind-routing table that maps surface names to handler IDs.

+700. **Top-level `help --output-format json` hangs behind the prompt spinner instead of returning bounded help JSON or a typed parse error** — dogfooded 2026-05-25 on freshly rebuilt `f9e98a263` during the 08:30 Clawhip nudge. Reproduction: `timeout 8 ./rust/target/debug/claw help --output-format json </dev/null` exits 124; stdout only shows spinner/TUI bytes and stderr is empty or only unrelated config warning depending on HOME. Positive control in the same rebuilt binary: `version --output-format json` returns promptly with `{kind:"version",status:"ok",git_sha:"f9e98a263"}`. This is adjacent to #699 but distinct: #699 covers `bootstrap-plan`/`dump-manifests` local subcommands falling through to prompt/auth; #700 covers the root bootstrap help surface itself. **Why it matters:** `help --output-format json` is the first command a wrapper or new claw probes to discover the CLI. A hanging help path forces every orchestrator to wrap discovery in external timeouts and cannot distinguish “unsupported JSON help” from “provider/auth prompt path accidentally started.” **Required fix shape:** (a) intercept top-level `help --output-format json` before prompt/provider startup; (b) return bounded JSON with `kind:"help"`, `status:"ok"`, command list, formats, and schema/version metadata, or if this argv order is intentionally unsupported, fail fast with `kind:"cli_parse"`, `status:"error"`, no spinner; (c) add regression proving `env -i HOME=/tmp/empty PATH=/usr/bin:/bin TERM=dumb ./rust/target/debug/claw help --output-format json </dev/null` exits within 1s without credentials.
