Structural Pre-Flight Skill
If you are about to author or relocate a .mjs file (new module, daemon, service, script, helper, etc.), you MUST immediately use the view_file tool to read and strictly adhere to .agents/skills/structural-pre-flight/references/structural-pre-flight-workflow.md before touching the filesystem.
The skill has two stages: a 30-second sibling-pattern fast-path AND a full Pre-Flight for novel directory choices. Always emit the explicit Pre-Flight reasoning-statement so future graph-traversal can audit the architectural choice.
