Keywords: skill, advanced, patterns." --- # Advanced Topics This document captures advanced considerations for evolving the skill system. --- ## Versioning - Keep the SSOT contract versionable: - `/.system/skills/ssot/**//SKILL.md` front matter fields (`name`, `description`) - `scripts/devops/skills/sync_skills.py` behavior and emitted wrapper format - Prefer additive changes; treat renames/removals as breaking (skills are user-facing identifiers). --- ## Dependencies and composition Some skills naturally depend on others (e.g., backend patterns often depend on error tracking). If dependencies are modeled: - Keep them explicit and minimal - Avoid deep dependency chains --- ## Governance - Skills should stay narrow and composable. - Large topics should be split into resources, not monolith docs. - Add alignment docs to clarify boundaries between overlapping skills/workflows.
