Code Style Matching
Before writing or modifying any code, match the project's exact code style.
Step 1: Load the Cached Style Index
Read(file_path: "$CLAUDE_PROJECT_DIR/.claude/code-style-index.json")
The index contains all formatting rules: indentation, quotes, semicolons, trailing commas, bracket spacing, import ordering, empty-line patterns, JSX formatting, and per-package overrides.
If the index exists (it should): apply all rules directly — skip to Step 2.
If the index does NOT exist: scan formatter configs (.prettierrc, .editorconfig, eslint.config.*) and 10-20 representative source files. Then create the index at $CLAUDE_PROJECT_DIR/.claude/code-style-index.json using the structure documented in the code-style skill's original template.
Step 2: Apply Exactly
- Match every observed convention — no exceptions, no personal defaults
- Never "improve" formatting — if the project uses tabs, use tabs
- Match empty line patterns, comment style, import ordering exactly
- When creating new files, match sibling files of the same type
Step 3: Update the Index
If you observe a style pattern not yet recorded in the index:
- Read the current index
- Add the new pattern
- Write it back
Never remove existing entries unless factually wrong.
