Signalpipe Tools (20)
signalpipe_get_missions
List pending leads awaiting review — score, role, channel, snippet, draft. Lean by default; opt into `include_context=true` only when drafting.

Get the drafting payload for a single mission so the host LLM can write the reply itself (BYOK path)
signalpipe_upload_draft
Upload a host-LLM-written draft to a mission
signalpipe_approve_mission

signalpipe_reject_mission
Reject a lead with a reason — teaches the per-station RL loop (penalty size adapts to the reason; demotes one noisy feed without dragging the rest of the product down). **Don't** use this when the post is just gone — use `signalpipe_delete_mission` instead.
signalpipe_delete_mission
Hard-delete a mission row — silent cleanup, no learning signal. Companion to reject. **Canonical case:** the post was deleted / 404'd / removed before you could reply.
