[WIP] Fix pre-flight validation gaps causing wasted sessions
fix: two-checkpoint pre-flight validation + PR closure reason labeling

@copilot a dedicated make agent_report_progress that runs in less than 30sec. |
Add a new Makefile target `agent_report_progress` that runs build + fmt + test-unit in under 30 seconds. This is the dedicated fast gate to run before every `report_progress` / create_pull_request call, replacing the ad-hoc `make fmt && make test-unit` guidance. - Makefile: add `agent_report_progress` target (build + fmt + test-unit) and update help text - AGENTS.md: update Checkpoint 2, Quick Reference, and MCP section to reference the new target; demote `make agent-finish` to "when more time is available" Agent-Logs-Url: https://github.com/github/gh-aw/sessions/0b025a4a-8c95-4c6e-add1-d90b485db64d Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Pull request overview
Updates agent validation guidance and tooling to reduce “opened-then-immediately-failing” PRs, and adds automation to label unmerged PR closures by likely root cause.
Changes:
- Document a two-checkpoint validation strategy in
AGENTS.md(early build/fmt, then a fast pre-report_progressgate). - Add a new lightweight Makefile validation target to standardize the pre-PR gate.
- Introduce a GitHub Actions workflow to label closed/unmerged PRs with a closure-reason label (CI failure / reviewer rejected / duplicate / unknown).

| File | Description |
|---|---|
| Makefile | Adds agent_report_progress and surfaces it in make help for a fast pre-PR validation gate. |
| AGENTS.md | Reframes agent validation rules into two checkpoints and updates the quick-reference checklist accordingly. |
| .github/workflows/label-closed-prs.yml | New workflow that inspects checks/reviews/labels on PR close (unmerged) and applies a closure-reason label. |

- In this section
test-unitis described as ~25s (viamake agent_report_progress), but later in the same document the Testing Strategy section saysmake test-unitis ~3 minutes (AGENTS.md:1208). Please reconcile these timings (or avoid hard-coded durations) so agents don’t make decisions based on conflicting guidance.
```bash
make agent_report_progress # build + fmt + test-unit (<30s) — fast pre-PR gate

fix:prefixes), largely because sessions skipped or deferred validation until afterreport_progress— by which point CI had already failed.AGENTS.md — Two-Checkpoint Validation Strategy
Replaces the single "before every commit" gate with an explicit two-stage model, under a renamed section heading "MANDATORY PRE-COMMIT AND PRE-PR VALIDATION":
Checkpoint 1 — immediately after the first substantial code edit:
Checkpoint 2 — hard gate before every
report_progresscall:make agent-report-progress # build + fmt + test-unit (<30s) — fast pre-PR gateWhen more time is available, prefer the full suite (
make agent-finish). The key addition to Checkpoint 2's rationale: "PRs that fail CI immediately after opening are closed without merging — a wasted session." Also updated the Quick Reference checklist and MCP inactivity timeout note to use the same two-checkpoint framing.Makefile—agent-report-progressTargetNew dedicated Makefile target (hyphen-separated, consistent with repo convention) that chains
build → fmt → test-unitand completes in under 30 seconds. This gives agents a fast, unambiguous gate to run before everyreport_progresscall without waiting for the fullagent-finishsuite.make agent-report-progress # build (~2s) + fmt (~1s) + test-unit (~25s).github/workflows/label-closed-prs.yml— Closure Reason LabelingNew workflow triggered on
