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.
