CI Parity Preflight

When to use

Use this skill for transport, plugin, feature-gating, or dependency-version changes that can affect CI matrix behavior.

Workflow

1. Run from repo root.
2. Prepare environment:
   • source build/envsetup.sh highest
3. Base matrix (no transport features):
   • cargo build
   • cargo clippy --all-targets -- -W warnings -D warnings
   • cargo fmt -- --check
4. Bundled transport matrix:
   • cargo build --features vsomeip-transport,bundled-vsomeip,zenoh-transport,mqtt-transport
   • cargo clippy --features vsomeip-transport,bundled-vsomeip,zenoh-transport,mqtt-transport --all-targets -- -W warnings -D warnings
5. Unbundled transport matrix (when transport/plugin code changed):
   • Set VSOMEIP_INSTALL_PATH to a valid vsomeip install tree.
   • cargo build --features vsomeip-transport,zenoh-transport,mqtt-transport
   • cargo clippy --features vsomeip-transport,zenoh-transport,mqtt-transport --all-targets -- -W warnings -D warnings
6. Workspace sanity:
   • cargo check --workspace --all-targets
   • cargo test --workspace

Guardrails

• Treat no-feature clippy and feature-enabled clippy as separate gates; passing one does not imply passing the other.
• If CI fails after local green, diff local command set against workflow YAML and rerun with exact flags.

Report template

Always capture:

1. Commands run
2. Pass/fail outcomes
3. Any environment variables used (VSOMEIP_INSTALL_PATH, stdlib paths)
4. If skipped, why skipped
