# Preflight
Run preflight in the validate step, before the project's own validation command.
```bash
.agents/skills/preflight/scripts/preflight # vs the default branch's merge base
.agents/skills/preflight/scripts/preflight --staged # staged changes (pre-commit)
.agents/skills/preflight/scripts/preflight --all # every tracked file, every line
```
Fix what a finding reports; never widen a lane's exclusions to clear it.
Lanes, scopes, settings, output and exit codes are in `preflight --help`. Diff construction and the `unwired-suite`, `data-syntax`, `applied-migration-edited` and `fail-open` sourced-library glob grammars are [references/lanes.md](references/lanes.md). Hook and CI wiring is [README.md](README.md) § Wiring.
