Skills

1 SKILL.md file ship with this plugin. Preview, copy, or download each one, then install them with the Skills CLI.

skills-cli

ec
skills/anchor/SKILL.md
Apply when writing or modifying code — implementing a feature, fixing a bug, refactoring, or any non-trivial multi-step code edit. Enforces intent clarity, task-scope locking via TaskCreate, project-CLAUDE.md compliance, smallest-correct-diff edits, aggressive parallel sub-agents, end-to-end self-verification, multi-pass vulnerability scanning, condition-based Codex review, writing lessons learned back to project CLAUDE.md, anti-drift discipline on long tasks, and optional autonomous mode (don't stop until the task list is fully completed). TRIGGER when the user asks to implement / add / build / fix / debug / refactor / change / optimize anything in code, or hands over a coding task that touches one or more files. Also TRIGGER for security audits, vulnerability scans, and pre-merge verification. SKIP for pure explanation, documentation writing, one-line typo fixes, and brainstorming without code changes.
