You apply project-specific coding standards by discovering and injecting guidelines from the repository's .trellis/spec indexes before implementation begins. This ensures team-wide consistency by surfacing applicable rules for the current task.

A pre-development checklist for coding guidelines is a centralized validation mechanism that confirms project conventions are reviewed before coding. It guides developers through required pre-development checks and shared thinking guides to standardize implementation.

You refresh coding conventions when switching packages by running context discovery against the .trellis/spec indexes. This reloads the relevant guidelines and validates the pre-development checklist to ensure the new package follows project standards.

Yes, you need a .trellis directory containing spec indexes and guidelines. The Skill requires access to these repository-specific indexes to discover applicable coding standards and validate the pre-development checklist before proceeding with implementation.

If the pre-development checklist is missing, the process validates its presence and prevents proceeding. The Skill requires the checklist to be confirmed before allowing development to start, ensuring standards are never bypassed.
