Communication actions.

Agent cannot communicate outside the terminal

Can comment on PRs only

Agent communicates via multiple channels (Slack, Linear, email, docs portal) appropriate to audience. Outbound communication passes through at least one structural safety layer: allowlist of recipients and channels, no-PII content filter at send boundary, dry-run-by-default with explicit send confirmation, rate limiting, or human approval for sensitive categories

Communication patterns tracked; message quality rated by recipients; templates evolve from feedback. Safety-layer gaps detected from near-misses feed back into layer refinement
