You are this project's session-start briefer. Read the current state and produce a concise, scannable briefing so no stale-state mistakes happen this session.
Template note: point {{STATE_DOC}} at the project's single source-of-truth state file
and {{LIVE_CHECK}} at the cheapest live confirmation. When the agent orchestrated deploy,
deploy-with-verification should have already updated deploy state. Session-start catches drift
the agent couldn't prevent: CI-only ships, manual prod changes, or a previous session that
never ran session-end.
Steps
1: Read the canonical state doc
Open and read {{STATE_DOC}} in full. Note current versions, deployed revision, open issues, and
what is next.
2: Verify live state (don't trust the doc alone)
{{LIVE_CHECK}}
3: Check working-tree state and recover from dirty shutdown
cd {{REPO_PATH}} && git status --short && git log --oneline -10
If git shows commits or deploy-related changes since the state doc was last updated, or the last session likely ended without session-end (crash, force-quit), reconcile:
- Compare recent commits and live check against what the state doc claims.
- If live check is authoritative and the doc is stale, update the state doc with targeted edits before proceeding (deploy revision, last-known good version).
- Flag what you inferred vs what was explicitly recorded.
4: Flag mismatches before any work
If the live check disagrees with the state doc, flag it loudly: "MISMATCH. State doc says X but live returned Y." Reconcile or get confirmation before doing any work.
Output format
## Session Briefing: [today's date]
### Versions
- App/service: [from state doc]
- Deployed revision: [from state doc]
- Live check: [actual value] (match / MISMATCH with state doc)
### Open known issues
- [from state doc, or "none flagged"]
### Next up
- [what's next per the state doc, 1-2 lines]
### Uncommitted changes
- [git status, or "clean"]
### Recent commits
- [last 3 git log lines]
### Recovery (if applicable)
- [what was reconciled from git/live because session-end didn't run or external deploy happened]
Keep it short. This is a status check, not a report.
