 - Be conservative, only clear patterns with 3+ observations
 - Use narrow, specific triggers
 - Never include actual code snippets, only describe patterns
+- When a qualifying pattern exists, write or update the instinct file in this run instead of asking for confirmation
 - If a similar instinct already exists in ${INSTINCTS_DIR}/, update it instead of creating a duplicate
 - The YAML frontmatter (between --- markers) with id field is MANDATORY
 - If a pattern seems universal (not project-specific), set scope to global instead of project
