 482. **Session-inspection slash aliases (`cost`, `stats`, `history`, `tokens`) have bounded bare/JSON resume-only errors, but `--help` hangs with zero output, extending the slash-alias help dead-end to the telemetry/recovery commands users need during stale-session debugging** — dogfooded 2026-05-20 from the `#clawcode-building-in-public` 06:00 UTC nudge on `/home/bellman/Workspace/claw-code-pr2967` with branch/origin `docs/roadmap-workdir-provenance@111e7e8` and binary `./rust/target/debug/claw` built from source SHA `25d663d`. Clean-home sweep showed local direct verbs behave differently: `diff` returns bounded no-git text/JSON and rejects `diff --help` with a bounded `unexpected extra arguments`; interactive-only write verbs (`commit`, `pr`, `issue`) return bounded bare/JSON errors and `--help` prints the global help. The broken cluster is the resume-safe telemetry alias family: `claw cost`, `claw stats`, `claw history`, and `claw tokens` each exit 1 with a useful resume-only message (`Use \`claw --resume SESSION.jsonl /<verb>\` or start \`claw\` and run \`/<verb>\`.`), and their `--output-format json` forms return bounded JSON error envelopes, but `claw cost --help`, `claw stats --help`, `claw history --help`, and `claw tokens --help` time out after 6s with `stdout=0`/`stderr=0`; the sweep had to be killed while stuck at `tokens --help`. **Required fix shape:** (a) fold the resume-safe telemetry slash aliases into the centralized slash-only alias help handler proposed in #481; (b) for each alias, return bounded text/JSON help listing the `--resume SESSION.jsonl /<verb>` form, accepted optional args (`history [count]`), and JSON support status; (c) do not fall through to prompt/runtime dispatch when `--help` follows any known slash alias; (d) add clean-home regressions for bare, `--help`, `help`, and JSON forms for `cost`, `stats`, `history`, `tokens`, `cache`, and `providers`. **Why this matters:** these commands are the observability surface for event/log opacity and stale-session confusion. If the first attempt to ask for help on `/tokens` or `/history` silently hangs, operators cannot tell whether the session store, runtime, or help parser is broken.

 483. **Interactive-only slash aliases (`approve`, `deny`, `model`) hang on `--help`, while `permissions --help` already returns bounded inline usage, proving the alias-help behavior is inconsistent within the same command family** — dogfooded 2026-05-20 from the `#clawcode-building-in-public` 06:30 UTC nudge on `/home/bellman/Workspace/claw-code-pr2967` with branch/origin `docs/roadmap-workdir-provenance@625b8b0` and binary `./rust/target/debug/claw` built from source SHA `25d663d`. Clean-home sweep: `claw approve`, `claw deny`, and `claw model` each exit 1 with a bounded interactive-only message (`Start \`claw\` and run \`/<verb>\` inside the REPL.`), and their `--output-format json` forms return bounded JSON error envelopes. But `claw approve --help`, `claw deny --help`, and `claw model --help` time out after 6s with `stdout=0`/`stderr=0`. Same sweep shows a nearby positive control: `claw permissions --help` exits 1 with the interactive-only message plus an inline usage block (`Usage /permissions [read-only|workspace-write|danger-full-access]`). Resume-safe siblings `cache`, `providers`, and `clear` also still hang on `--help`, matching #481/#482. **Required fix shape:** (a) extend the centralized slash-alias help handler to interactive-only aliases, not just resume-safe aliases; (b) model it after the existing bounded `permissions --help` behavior, returning the interactive-only reason plus per-command usage; (c) include aliases (`/approve` = `/yes`/`/y`, `/deny` = `/no`/`/n`) in help text/JSON; (d) add clean-home regressions for `approve --help`, `deny --help`, `model --help`, `debug-tool-call --help`, and assert `permissions --help` remains bounded. **Why this matters:** permission prompts and model switching are high-friction startup/operator surfaces. If users naturally type `claw approve --help` or `claw model --help`, the CLI must explain that these are REPL-only instead of silently hanging and looking like a dead runtime.

+484. **Interactive helper slash aliases (`debug-tool-call`, `bughunter`, `teleport`) hang on `--help`, and argument-bearing invocations like `bughunter src --output-format json` also hang instead of returning an interactive-only error, so high-value debug/navigation entrypoints are misclassified as dead runtime work** — dogfooded 2026-05-20 from the `#clawcode-building-in-public` 07:00 UTC nudge on `/home/bellman/Workspace/claw-code-pr2967` with branch/origin `docs/roadmap-workdir-provenance@dbd04ad` and binary `./rust/target/debug/claw` built from source SHA `25d663d`. Clean-home sweep: `claw bughunter` and `claw teleport` exit 1 with bounded interactive-only messages (`Start \`claw\` and run \`/<verb>\` inside the REPL.`), but `claw debug-tool-call --help`, `claw bughunter --help`, and `claw teleport --help` each timed out after 6s with `stdout=0`/`stderr=0`. Worse, a realistic argument-bearing form, `claw bughunter src --output-format json`, also timed out after 6s with zero output instead of saying `/bughunter` is REPL-only; the sweep had to be killed after `teleport --help` hung. **Required fix shape:** (a) classify debug/navigation slash aliases before prompt/runtime fallback, including when they carry positional arguments; (b) return bounded interactive-only help for `debug-tool-call`, `bughunter [scope]`, and `teleport <symbol-or-path>`; (c) for JSON mode, return an error envelope with `kind:"slash_command_repl_only"`, `slash`, `args`, and `usage`; (d) add clean-home regressions for bare, `--help`, JSON, and argument-bearing forms (`bughunter src`, `teleport main`, `ultraplan task`, `release-notes`). **Why this matters:** these are the tools operators reach for to diagnose brittle tests, find files, or replay tool calls. Hanging before the REPL boundary makes a simple usage mistake indistinguishable from prompt misdelivery or a stuck MCP/plugin lifecycle.
