Endpoint

Draft from signal

POST/api/public/v1/campaigns/{campaign_id}/signals/{signal_id}/draftwrite

Write an opener from one signal (a discovered_posts id from list_signals). For a person with a draft it rewrites message 1 through the same path as request_rewrite (hard-fail QA gate, cost cap, audit), anchored on their own post; for a person with no draft yet it selects them and nudges the run. Spends model calls. Writes a draft only: nothing is approved or sent.

Scope required: write. How scopes work.
Accepts Idempotency-Key. A retry with the same key replays the first result instead of repeating the work.
Same capability over MCP as the tool draft_from_signal. MCP setup.
