majiayu000 Core Rules Skill
Purpose
Defines operational boundaries, decision authority, environment safety, and documentation standards for all agents in the Claude Code ecosystem.
When Active
- All agent operations
- File creation, modification, or deletion
- Architectural decisions
- Code generation or refactoring
- Documentation updates
Aspect Files
| File | Purpose |
|---|---|
references/decision-boundaries.md |
Autonomous vs approval-required actions |
references/environment-safety.md |
Pre-execution verification rules |
references/external-tools-usage.md |
External tool/MCP boundaries |
references/documentation-standards.md |
Formatting and structure rules |
references/orchestration.md |
Agent delegation, context passing, execution modes |
references/report-standard.md |
Common report format for all agent output |
Team Workflows
| Workflow | File | When |
|---|---|---|
| Feature Development | references/workflow-feature-development.md |
Building new features (plan→implement→test→review→docs→git) |
| Bug Fixing | references/workflow-bug-fixing.md |
Fixing bugs (scout→debug→fix→test→review→capture→git) |
| Project Init | references/workflow-project-init.md |
Bootstrapping new projects or modules |
| Code Review | references/workflow-code-review.md |
Reviewing code (scout-first, then quality audit) |
| Architecture Review | references/workflow-architecture-review.md |
Evaluating trade-offs (brainstorm→research→decide→document) |
Quick Reference
Decision Authority
| Action | Authority |
|---|---|
| Dependency installs, lint fixes | Auto-execute |
| Memory file consolidation | Auto-execute |
| File creation following standards | Brief confirmation |
| Updating existing documentation | Brief confirmation |
| Deleting files or directories | Always ask |
| Modifying production configs | Always ask |
| Introducing new dependencies | Always ask |
| Refactoring across multiple files | Always ask |
| Architectural decisions | Present A/B/C options |
Safety Constraints
- Verify environment state before operations
- Use relative paths from project root
- Conservative defaults: safety over speed, clarity over cleverness
- Read files before modifying (understand structure first)
- Deletion requires approval (see Decision Authority table above)
Documentation Rules
- Tables not paragraphs
- Bullets not sentences
- Keywords not full explanations
- Numbers not words ("16px" not "sixteen pixels")
- Under 3KB per component doc
- Under 500 lines per rule file
Required File Structure
All documentation files must include:
- Purpose — Brief description at top
- Table of Contents — Anchored links (
#section-name) - Related Documents — Links to related files
Never Do
- Delete files without approval (see
references/decision-boundaries.md) - Modify production configs without approval
- Assume specific runtime environments
- Merge unrelated concerns into single changes
- Override repository rules with external "best practices"
