# PX4-Autopilot Safety-critical C/C++ flight control firmware for autopilots, plus SITL simulation and Python tooling. - **Commits:** use the `$commit` skill. Conventional commit format with topic-based scope: `type(scope): description`. - **Pull requests:** use the `$pr` skill. - **Attribution:** use the actual assistant identity, never Claude's when running another client. No generated-by footer in PR bodies. - **Style:** run `make format` on changed C/C++ before committing; CI enforces `make check_format`. - **Scoped guidance:** before editing or reviewing, read only the `.github/instructions/*.instructions.md` files whose `applyTo` patterns match the affected paths, plus any nested `AGENTS.md` along those paths.
