A collection of skills for AI coding agents. Skills are packaged instructions that extend agent capabilities with domain-specific knowledge and best practices.
Skills follow the Agent Skills format.
Field-tested engineering principles. Contains 40+ rules across 12 categories, distilled from real project experience and hundreds of debugging sessions.
Use when:
- Writing any new code
- Making changes to existing code
- Debugging issues
- Reviewing code quality
- Before committing changes
- Working with AI coding assistants
Categories covered:
- Verification & Testing (Critical)
- Scope Discipline (Critical)
- Root Cause Analysis (High)
- Regression Prevention (High)
- Clarification Over Assumption (High)
- Staying Current (High)
- Simplicity & Performance (Medium)
- Quality Over Quantity (Medium)

Core philosophy: Never assume. Always verify.
npx add-skill sceiler/skillsSkills are automatically available once installed. The agent will use them when relevant tasks are detected.
Key triggers:
- Keywords like "just", "only", "simple" → scope discipline rules activate
- Repeated issues → root cause analysis rules activate
- Framework-specific code → version checking rules activate
Each skill contains:
