Triage

1. Fetch the issue(s). Search for duplicates by title/topic (search_issues), and check ROADMAP §5.
2. Pick the milestone using ROADMAP §4 — the earliest milestone whose release needs it. Anything not required by M0–M6 goes to M7/M8/M9.
3. Pick labels from .github/labels.json: exactly one type:*, one or more area:*, provider:* if vendor-specific, priority:critical-path if it blocks a release.
4. Check acceptance criteria are verifiable; if not, draft sharper criteria.
5. Write changes to the repo files first (.github/milestones.json, ROADMAP tables), then apply to GitHub with scripts/sync-milestones.sh (or MCP issue_write) — only when the user has asked you to modify GitHub. Otherwise present the proposal.
6. Closing duplicates: comment Duplicate of #N, close with state_reason: duplicate, and only with user approval.
