Local ship gate for coding agents

One last check before you ship.

Preflight reads the change, finds grounded blockers, and returns a verdict your agent can act on. It runs locally and uses the coding CLI you already have.

The product

A verdict, not another wall of output.

Preflight collapses multiple model opinions, code context, and local verification into one calm decision surface.

No test covers the new error path.

src/greet.ts:2 · F1

The new throw path changes public behavior, but no test protects blank and whitespace-only names.

FixAdd one focused unit test before shipping.

The loop

From diff to decision in three passes.

Each stage removes noise and adds evidence, so the final result is short enough for a human and structured enough for an agent.

01 / Prove

Capture and run the change.

Staged, unstaged, and untracked files plus native typecheck, lint, test, and build evidence.

02 / Judge

Ground every finding.

Multiple CLIs agree behind one verdict, with confidence and exact hunks.

03 / Act

Return a clear gate.

Exit 0 means ship. Exit 2 includes fixable findings and delta re-review.
