 341. **Resume-safe `/tasks --output-format json` emits an unsupported-command JSON error only on stderr and mixes `kind` with `type` classification vocabularies** — dogfooded 2026-04-29 for the 16:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `58569131`. Running `./rust/target/debug/claw --resume latest /tasks --output-format json` wrote no stdout bytes, but wrote a JSON error object to stderr: `{"command":"/tasks","error":"/tasks is not yet implemented in this build","kind":"unsupported_command","type":"error"}`. The unsupported command envelope therefore has two separate top-level classification vocabularies (`kind=unsupported_command` and `type=error`) and places the only parseable payload on stderr, while successful JSON commands use stdout and a `kind`-only classification. This is distinct from #340 because it is not session help; it shows implemented-but-unsupported command stubs can emit a dual-vocabulary error envelope. **Required fix shape:** (a) in `--output-format json` mode, emit the primary JSON envelope on stdout for unsupported resumed slash commands such as `/tasks`; (b) document and use one error discriminator, preferably `kind:"error"` plus `code:"unsupported_command"`, or `kind:"unsupported_command"` plus `status:"error"`, but not `type`; (c) reserve stderr for non-primary diagnostics or text-mode prose, never as the sole JSON payload; (d) add regression coverage for `/tasks` under `--resume` with JSON output proving stdout contains the structured error envelope, stderr is not the only parseable stream, and the envelope uses the documented single-vocabulary discriminator. **Why this matters:** claws need the same stdout JSON contract for implemented successes and implemented-but-unsupported stubs. If `/tasks` errors can silently move to stderr and advertise both `kind` and `type`, automation must special-case command stubs instead of applying one JSON error parser.

 342. **Resume-safe `/commands --output-format json` is rejected as an unknown slash command even though the error points users at `/help` for slash-command discovery, leaving no structured command-index alias** — dogfooded 2026-04-29 for the 16:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `f65b2b4f`. Running `./rust/target/debug/claw --resume latest /commands --output-format json` wrote no stdout bytes and emitted only stderr JSON: `{"command":"/commands","error":"Unknown slash command: /commands\n  Help             /help lists available slash commands","type":"error"}`. In the same rebuilt binary, `./rust/target/debug/claw --resume latest /help --output-format json` succeeded on stdout but exposed only prose keys `kind,text`. The discoverability path therefore has two gaps at once: the intuitive `/commands` index/alias is unavailable, and the fallback suggestion is buried inside an error string rather than surfaced as structured `suggested_command` / `discovery_command` metadata. This is distinct from #340 and #341: the pinpoint is not merely stderr-only JSON error placement, but the absence of a machine-readable slash-command discovery alias/index and typed correction guidance when users or claws try the natural `/commands` form. **Required fix shape:** (a) either implement `/commands` as a resume-safe alias for slash-command discovery or return a typed `unknown_command` JSON envelope with `suggested_command:"/help"` and `discovery_command:"/help"` fields; (b) make the primary JSON error envelope follow the stdout JSON contract and single-discriminator schema from #340/#341; (c) expose structured slash-command inventory from the discovery surface rather than requiring callers to scrape `text`; (d) add regression coverage proving `/commands --output-format json` either returns the structured command inventory or returns a structured correction that automation can follow without parsing prose. **Why this matters:** claws need a predictable way to discover valid slash commands before invoking them. If the natural command-index spelling fails with stderr-only JSON and a human-formatted hint, orchestration has to guess, parse prose, and special-case command discovery before it can even learn the supported command surface.

-343. **Resume-safe `/models --output-format json` suggests `/model` as a correction even though `/model` is itself unsupported in the same resume-safe JSON path** — dogfooded 2026-04-29 for the 17:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a1bfcd41`. Running `./rust/target/debug/claw --resume latest /models --output-format json` wrote no stdout bytes and emitted stderr JSON: `{"command":"/models","error":"Unknown slash command: /models\n  Did you mean     /model, /tokens\n  Help             /help lists available slash commands","type":"error"}`. Immediately following the suggested correction with `./rust/target/debug/claw --resume latest /model --output-format json` also wrote no stdout bytes and returned `{"command":"/model","error":"unsupported resumed slash command","type":"error"}`. The correction path therefore points automation from an unknown plural form to a command that cannot run in the same resume-safe noninteractive mode, while `/tokens --output-format json` succeeds and exposes only token counters. This is distinct from #342's missing `/commands` discovery alias: the pinpoint here is dead-end suggestion quality and resume-safety awareness in `Did you mean` guidance. **Required fix shape:** (a) make unknown-command suggestions context-aware so resume-mode JSON only suggests commands that are actually resume-safe for the current invocation, or labels non-resume-safe suggestions with `resume_safe:false`; (b) expose suggestions as structured `suggestions[]` objects with `command`, `resume_safe`, `reason`, and optional `replacement_for` fields instead of burying them in the `error` string; (c) if `/model` remains interactive-only, suggest a machine-readable status/config/model inspection command that works under `--resume`, or return a typed `interactive_only` blocker; (d) add regression coverage proving `/models --output-format json` does not recommend an unusable `/model` command without structured resume-safety metadata. **Why this matters:** claws follow correction hints automatically. A suggestion that leads straight into another unsupported resumed slash command turns error recovery into a loop and makes command discovery less trustworthy than no suggestion at all.

-344. **Resume-safe `/config help --output-format json` is treated as an unsupported config section instead of a structured config-section discovery surface** — dogfooded 2026-04-29 for the 18:30 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a510f734`. Running `./rust/target/debug/claw --resume latest /config help --output-format json` wrote no stdout bytes and emitted stderr JSON: `{"command":"/config help","error":"Unsupported /config section 'help'. Use env, hooks, model, or plugins.\n  Usage            /config [env|hooks|model|plugins]\n\n/config\n  Summary          Inspect Claude config files or merged sections\n  Usage            /config [env|hooks|model|plugins]\n  Category         Config\n  Resume           Supported with --resume SESSION.jsonl","type":"error"}`. The same shape appears for natural discovery forms such as `/config list` and `/config show`, while bare `/config --output-format json` succeeds and returns config-file data. The config surface is therefore resume-supported, but its section discovery/help path is only available as a human-formatted error string on stderr, with no structured `sections[]`, no `help` alias, and no typed `unsupported_section` metadata. This is distinct from #342's missing slash-command index and #343's dead-end suggestion: the pinpoint is a command-specific subcommand/section discovery contract for an otherwise working resume-safe command. **Required fix shape:** (a) make `/config help` or `/config sections` resume-safe and return stdout JSON containing supported sections such as `env`, `hooks`, `model`, and `plugins`; (b) for unsupported config sections, emit a typed JSON envelope with `kind:"error"` or equivalent plus `code:"unsupported_config_section"`, `section`, and structured `supported_sections[]`; (c) keep human usage text optional, not the only machine-readable recovery path; (d) add regression coverage proving `/config help --output-format json` or its canonical replacement exposes structured section metadata and that `/config list`/`show` errors include structured supported-section guidance. **Why this matters:** config inspection is a control-plane surface. Claws should not have to intentionally trigger an error and scrape prose to learn which config sections can be inspected under `--resume`; section discovery needs the same machine-readable contract as the config payload itself.

-345. **Resume-safe `/config env|hooks|model|plugins --output-format json` accepts different section names but returns the same generic config-file summary for every section** — dogfooded 2026-04-29 for the 19:00 nudge on current `origin/main` / rebuilt `./rust/target/debug/claw` with embedded `git_sha` `a510f734`. Running `./rust/target/debug/claw --resume latest /config env --output-format json`, `/config hooks`, `/config model`, and `/config plugins` all wrote stdout JSON successfully and no stderr, but each response had the same top-level shape and values: `kind:"config"`, `cwd`, `files[]`, `loaded_files:1`, and `merged_keys:1`. None of the outputs included the requested `section`, section-specific keys, hook/model/plugin/env data, `section_missing`, `section_empty`, or truncation metadata; the `env`, `hooks`, `model`, and `plugins` arguments appear to be accepted while producing an indistinguishable generic config summary. This is distinct from #344's missing config-section discovery/help path: the pinpoint here is that the advertised section-specific entrypoints do not produce section-specific machine-readable payloads once invoked. **Required fix shape:** (a) include a `section` field in `/config <section> --output-format json` responses; (b) return section-specific structured payloads for `env`, `hooks`, `model`, and `plugins`, with explicit empty/missing states when applicable; (c) preserve the config-file provenance summary separately from the requested section content so callers can tell what was inspected; (d) add regression coverage proving the four supported sections produce distinguishable JSON contracts and do not silently collapse to the bare `/config` summary. **Why this matters:** config inspection is used to diagnose model, hook, plugin, and env lifecycle issues. If every supported section returns the same generic file list, claws cannot tell whether a section is empty, unsupported, redacted, or simply ignored, and config troubleshooting remains prose/error archaeology instead of structured state inspection.

-354. **`/cwd` slash command is not implemented but the fuzzy-match "Did you mean" suggestion returns `/cwd` itself, creating a self-referential error loop** — dogfooded 2026-04-30 by Jobdori on `c6c01bea`. Running `/cwd --output-format json` returns `{"command":"/cwd","error":"Unknown slash command: /cwd\n  Did you mean     /cwd, /chat, /copy\n  Help...","type":"error"}`. The command reports itself as unknown and then suggests itself as the correction. A user who follows the suggestion types `/cwd` again, gets the same error, and is stuck in an infinite loop with no way to reach the current working directory via a slash command. The correct working directory information is available via `status --output-format json` as `workspace.cwd`, but there is no dedicated `/cwd` command. **Required fix shape:** (a) either implement `/cwd` to return `{"kind":"cwd","cwd":"/current/path"}` (consistent with `/status`'s `workspace.cwd`), or (b) remove `/cwd` from the fuzzy-match candidate list entirely so it does not appear in "Did you mean" suggestions when it cannot be executed. As a secondary fix, the fuzzy-match algorithm should filter out commands whose `status` is `unsupported` or `not-yet-implemented` so they are never surfaced as suggestions.

+347. **`/session list --output-format json` returns `"title": null` for every session; sessions have no human-readable label and can only be distinguished by their timestamp-based ID** — dogfooded 2026-04-30 by Jobdori on `a1bfcd4`. Running `/session list --output-format json` returns `session_details` where every entry has `"title": null`. The `id` field is a machine-generated string such as `session-1776891003038-0` (millisecond epoch). There is no `/session rename <id> <title>` command, no auto-derived title (e.g. from the first user message or the git branch at session start), and no way to programmatically query "which session was working on feature X" without replaying the message history. In a multi-session workflow with 10+ sessions, an orchestration layer cannot build a human-readable session picker without fetching and reading message content from every session file. **Required fix shape:** (a) auto-derive `title` from the first user message (first N chars, truncated) or from the git branch name at session creation time; (b) expose a `/session rename <id> <title>` slash command so users can label sessions manually; (c) persist title in the session store so it survives restarts; (d) include the `title` field in `session_details` JSON response — even if the value is auto-derived and mutable; (e) add `created_at_ms` (tracked in #335) alongside title so sessions are fully sortable and labelable without reading message content.
