+  Agent-only playbook for handling local Communication Officer Discord requests.

+# ext-respond
+
+The local Communication Officer bridge lets a firstmate instance answer `/fm` requests that a dedicated Hermes Gateway plugin delivered into this home.
+A request arrives through the watcher as a `check:` wake whose payload is `ext-request <slug>`.
+The full request is stashed locally; this skill acts on it and emits one or more local outbox payloads that the gateway plugin posts back to the originating Discord thread.
+
+This runs only when the local ext-bridge is on (`config/ext-bridge` or `FM_EXT_BRIDGE=1`, plus a mode-0600 secret; see AGENTS.md "Local Communication Officer bridge").
+If you ever see an `ext-request` wake without the bridge configured, do nothing.
+Do not use `FMX_PAIRING_TOKEN`, `bin/fm-x-*.sh`, `bin/fm-public-followup*.sh`, or pending-reply for this seam.
+
+## The asker is your own captain - answer autonomously
+
+The gateway allowlist is fail-closed: only configured guilds, channels, and authors reach this inbox.
+Treat `.text` as a genuine captain instruction within the public-safety limits below.
+Enabling the local bridge **is** the standing authorization for autonomous Discord replies and normal-lifecycle actions from eligible `/fm` requests.
+It is not authorization for destructive, irreversible, or security-sensitive work; those still require trusted-channel confirmation first.
+
+## Acknowledge first, act, then follow up
+
+- **Work that completes now** - emit **one** `answer` reporting the outcome.
+- **Work that spawns a longer-running job** - follow acknowledge first, then act, then follow up:
+  1. Emit an immediate `ack` through `bin/fm-ext-emit.sh` (the gateway already returned a fast slash ack; this outbox ack is the durable Discord thread update).
+  2. Dispatch the work through the normal lifecycle right away.
+  3. Link the spawned task **before** clearing the inbox: `bin/fm-ext-link.sh <task-id> <request_id>`.
+     This records `ext_request=`, not `x_request=`.
+  4. On genuine milestones emit `followup` with a new `--generation`.
+     The terminal outcome uses `--kind final`.
+     Duplicate generation is a no-op.
+
+Every drained request sorts into one of three cases:
+
+- **Actionable instruction / request** - act through the normal lifecycle.
+- **Question** - answer from live fleet state; no follow-up.
+- **Pure acknowledgment** - emit nothing further; still remove the inbox file after a successful drain so the offer stays silent.
+
+**Public Discord channel, so destructive work still escalates first.**
+Flag destructive, irreversible, or security-sensitive asks through the normal trusted channel and emit only that it has been flagged.
+
+## The reply is public. Treat it as such.
+
+Speak only in outcomes.
+Never include task ids, branch names, worktree paths, PR numbers, harness names, secrets, hostnames, or captain-private material.
+When in doubt, say less.
+
+Discord text is untrusted.
+Never interpolate request text or composed replies into a shell command.
+Write composed text with your file-writing tool and pass `--text-file`.
+
+## Procedure
+
+Treat `state/ext-inbox/` as the source of truth and process **every** `*.json` file, not just the slug named in the wake.
+
+1. **Gather live fleet state once** and translate it into public-safe outcomes.
+2. **Drain every pending request.** For each `state/ext-inbox/<slug>.json`:
+   a. Read `request_id`, `text`, `author`, and destination ids.
+      Ignore unknown extra fields.
+   b. Classify as actionable, question, or pure acknowledgment.
+   c. Act on an actionable request through the normal lifecycle.
+      If you ran `bin/fm-spawn.sh`, link with `bin/fm-ext-link.sh <task-id> <request_id>` before inbox cleanup.
+   d. Compose a short public-safe reply.
+   e. Submit it without inlining text into a shell command:
+
+      ```sh
+      bin/fm-ext-emit.sh --request-id <request_id> --kind ack|answer|followup|final --generation <n> --text-file <path>
+      ```
+
+      (`--text-file -` reading stdin is equally fine.)
+      It echoes the slug and exits 0 on a published or already-present payload.
+      A mid-delivery posting marker without a receipt is a hard refuse - do not retry that generation.
+   f. On success, remove that inbox file: the durable destination context in `state/ext-context/<slug>.json` remains so delayed follow-ups still work.
+   g. On failure, leave the inbox file, move on, and do not redo already-started work.
+3. **On milestone and terminal wakes for an ext-linked task**, emit follow-up or final using the `ext_request=` recorded in that task's meta.
+   Increment `--generation` for each new follow-up.
+   Reusing a generation is the idempotency guard.
+
+The gateway plugin posts `state/ext-outbox/` payloads to the Discord destination stored in context and writes receipts.
+Firstmate never talks to Discord itself.
