BRIEFING_PROMPT="Daily briefing request (automated, $(date -u '+%Y-%m-%d')):

Produce a concise morning briefing covering:
1. Pipeline status — blocked issues, failing CI, stale PRs?
2. Recent activity — what merged/closed in the last 24h?
3. Backlog health — depth, underspecified issues?
4. Predictions — any unreviewed from the predictor?
5. Concerns — anything needing human attention today?

Check the forge API, git log, agent journals, and issue tracker.
Under 500 words. Lead with what needs action."
