maintain-project-rules

Activation gate

Use if:

• User asks to audit or maintain project rules, check prefix convention, or sync doc/rules.md.
• Context involves .cursor/rules/, rule files (.mdc), or conventions from cursor-rules-principles / retro.

Source of truth

• cursor-rules-principles.md (in repo or ~/.cursor) – prefix table 000–500, general principles. See reference.md for full prefix table.
• commands/retro.md (PROJECT RULES section) – prefixes 000/050/100/200/900, flat .mdc, no subfolders in rules.

Procedure

1. Resolve paths

   • PROJECT_ROOT: git rev-parse --show-toplevel
   • PROJECT_CURSOR_DIR: ${PROJECT_ROOT}/.cursor
   • PROJECT_RULES_DIR: ${PROJECT_CURSOR_DIR}/rules
   • If PROJECT_RULES_DIR does not exist, report “No .cursor/rules in this repo” and stop.

2. Audit

   • List all *.mdc in PROJECT_RULES_DIR (flat; no subfolders per convention).
   • For each file: name, prefix vs principles/retro, frontmatter (description, alwaysApply, globs), line count (~<50 preferred), overlap with other rules (duplicate or near-duplicate content).
   • Flag: missing prefix, wrong prefix slot, missing/invalid frontmatter, oversized file, duplicate content.

3. Proposals

   • RENAME: file without numeric prefix → suggest prefix from reference.md / retro.
   • MERGE: two or more rules with overlapping scope → suggest target file and sections.
   • DELETE: only with clear justification (obsolete, fully merged); do not execute without user confirmation.
   • Do not delete, move, or rename until user confirms.

4. Sync doc/rules.md

   • If repo has doc/rules.md or docs/rules.md: update the “Context-Specific Rules” (or equivalent) list to match current .mdc files and their globs/scope. Keep doc and rules directory in sync.

Output

• Report: table of files (path, prefix OK?, frontmatter OK?, lines, notes); list of proposals (RENAME/MERGE/DELETE with reason and target).
• Closing line: “Do zastosowania: potwierdź zmiany lub wywołaj agenta rules-keeper.”
• No destructive changes without explicit user confirmation.
