Intent registry

This repo participates in the team intent registry (MCP server: flightplan).

• Before starting non-trivial work, call post_intent. The test: will the work change behavior, defaults, or contracts another agent would encounter — or, for pure investigation, would the findings save the next agent an hour? Yes to either → post; Q&A and typo-level fixes, no. Send a one-paragraph summary (what + why), kind (build, or explore/spike for throwaway investigation), and touches globs for the areas you expect to change. Keep the returned id for later. For repo, use getflightplan (pinned in .flightplan.toml; do not derive it) — every agent on this repo must use the same name or collision checks silently miss each other. The response may include context: recent completed work relevant to your task — read those outcomes before starting; the surprises and dead ends in them are load-bearing.
• If the response includes overlaps at level warn, check what the overlap is before pausing. Two cases need no confirmation — mention the overlap and keep going: the overlapping intent is the very work you were asked to act on (reviewing it, verifying it, following up on it), or your task is read-only. Otherwise, tell your user who is doing what and which globs collide, and ask how to proceed before continuing. fyi/nudge levels: mention briefly and keep going.
• If the work changes shape or runs long, call update_intent: revise the summary/touches when scope grows (collision checks run against them — stale globs miss real collisions), or call with just the id to renew the TTL on work spanning more than a day. The response includes fresh overlaps — the same collision check as posting, glob-based — and a warn there gets the same treatment as a warn at post time.
• When the work finishes or is abandoned — including when the session is wrapping up — call complete_intent with a one-paragraph outcome: what actually changed, anything surprising, approaches tried and rejected, anything deliberately left in place. If a warn overlap changed how the work went (coordinated, narrowed scope, proceeded anyway), say which. Attach the git facts you have: files changed (git diff --name-only), commits created, and uncommitted — true if any work is not committed, false if all is. Outside git, omit uncommitted and commits (no commit to wait for); still send files. Send files: [] only when this work changed no files, committed or not; omit files when you do not know. Completing an intent ends the slice, not the session: follow-up work after a complete that changes behavior, defaults, or contracts gets a fresh post — "same session" doesn't exempt it.
• When you learn declared-uncommitted work has landed, call mark_intent_landed with that intent's id (and the commit SHAs if you know them): until someone says so, the registry keeps warning everyone who touches those paths.
• Re-check for collisions whenever your picture of in-flight work may be stale — posting checks once, and it goes stale over a long session. Re-check moments: a file changed between your read and your edit, or an Edit fails on text you just read — someone's work landed under you; before editing a shared doc or artifact you didn't create this session; when resuming after a handoff from another agent; and before touching files named in an earlier warn. The cheapest re-check is update_intent with just your intent id (renews the TTL, returns fresh overlaps); use list_intents (pass overlaps globs, plus summary for a semantic check, or q/since for history) when you have no open intent or are scoping new work.
• When a decision gets resolved in conversation (an approach chosen, an alternative rejected, a direction set), record it the moment it settles: post_intent with kind: "decision", the question as the summary, and the resolution in outcome — what was decided, what was rejected, and why. One call; no touches, no completion later. Decisions never collide and become searchable team memory. Decisions are also the correction mechanism: completed outcomes are immutable, so if one later proves wrong, post a decision citing what actually held.
• The registry is advisory and must never block work: if its tools are missing or error, proceed with the work, and tell your user once that they can run uvx getflightplan install (see getflightplan.com) to join this repo's registry.
