Patterns

Use this skill as the shared baseline. Repository instructions and versioned project-local patterns are the profile for that repository and override this skill when they are more specific.

Apply the guidance

1. Read the repository's AGENTS.md and any project-local pattern index it names before choosing a shared pattern.
2. Search the pattern index for task keywords. Read only the matching pattern files and any directly linked reference. When either the task or the change being implemented or reviewed proposes a new capability, guarantee, abstraction, compatibility path, or cross-owner coordination mechanism, read the indexed YAGNI and coordination-cost pattern before implementation or review.
3. Apply the demonstrated invariant to the current code. The code in each pattern shows the preferred shape; @bad tags identify rejected shapes.
4. Keep the change scoped. Do not mechanically rewrite unrelated code merely because another pattern exists.

When no indexed pattern matches, follow the repository and user instructions; do not infer a universal rule from one example.

Source boundary

This skill applies guidance from the live morgs32/llm-wiki checkout. To change shared patterns or any installable skill, edit that repository's skills/** tree (global via the ~/.agents/skills symlink) and use the repo-local $update-morgs32-llm-wiki workflow to publish.

~/.agents/skills is a symlink into this repository's skills/ directory. Edit skills in the checkout; do not maintain a second global copy.
