Real-time library documentation - Framework best practices - Code examples ### Playwright MCP - Browser automation - E2E testing capabilities - UI interaction ### Fetch MCP - Web content retrieval - API testing ``` --- ## Missing Capabilities Summary Table | Capability | Commands | Agents | Skills | Output Styles | CLAUDE.md | |------------|----------|--------|--------|---------------|-----------| | **`model` frontmatter** | 🔴 Missing | 🔴 Missing | 🔴 Missing | 🟡 Partial | N/A | | **`allowed-tools` patterns** | 🟡 Basic | 🔴 Missing | 🟡 Basic | N/A | N/A | | **Extended thinking** | 🔴 Missing | 🔴 Missing | 🔴 Missing | N/A | 🔴 Missing | | **Tool inheritance** | 🔴 Missing | 🔴 Missing | 🔴 Missing | N/A | N/A | | **Storage locations** | ✅ Good | 🟡 Partial | 🟡 Partial | ✅ Good | N/A | | **Invocation mechanism** | ✅ Good | 🟡 Missing | 🟡 Partial | ✅ Good | N/A | | **Model selection strategy** | 🟡 Partial | 🔴 Missing | 🔴 Missing | 🟡 Partial | N/A | | **MCP integration** | ✅ Excellent | ✅ Excellent | ✅ Good | ✅ Good | 🔴 Missing | | **Hooks integration** | 🟡 Mentioned | 🟡 Mentioned | 🟡 Mentioned | 🟡 Mentioned | 🟡 Minimal | **Legend**: - ✅ Well-implemented - 🟡 Partial/needs improvement - 🔴 Missing or critically incomplete - N/A = Not applicable --- ## Priority Recommendations ### 🔥 Critical (Must Add) 1. **Add `model` frontmatter to all templates** - Commands Template: Lines 4-5 (add after allowed-tools) - Agent Template: Lines 3-4 (add to frontmatter example) - Skills Template: Lines 5-6 (add to frontmatter) - Add model selection strategy sections to each 2. **Expand `allowed-tools` documentation** - Add comprehensive pattern examples - Show Bash command-specific patterns - Document tool inheritance - Add MCP tool patterns 3. **Add extended thinking documentation** - Commands Template: New section after "Advanced Features" - Agent Template: New section in workflow - CLAUDE.md: New section in "Claude Code Specific Instructions" ### 🟡 High Priority (Should Add) 4. **Document agent/skill invocation mechanisms** - Agent Template: Add "How This Agent is Invoked" section - Skills Template: Strengthen "Skills are model-invoked" emphasis 5. **Add frontmatter configuration sections** - Agent Template: Complete frontmatter documentation - Output Styles Template: Clarify supported frontmatter fields 6. **Enhance storage location documentation** - All templates: Add clear user vs project distinction - Document plugin integration paths ### 🔵 Medium Priority (Nice to Have) 7. **Add model selection strategies** - Performance vs cost tradeoffs - Task-appropriate model selection - Token efficiency guidance 8. **Expand hooks integration** - CLAUDE.md: Add comprehensive hooks section - All templates: Reference available hooks 9. **Add MCP server documentation** - CLAUDE.md: Add "Available MCP Servers" section - List capabilities and use cases --- ## Strengths of Current Templates ### What's Already Excellent 1. **MCP Integration** 🏆 - Best-in-class documentation of Serena vs Memory MCP usage - Clear persistent vs temporary distinction - Excellent use case examples 2. **Argument Handling** 🏆 - Comprehensive $ARGUMENTS, $1, $2 documentation - Multiple examples and patterns - Clear integration with other features 3. **File References** 🏆 - Well-documented @ syntax - Good examples across multiple scenarios - Integration with arguments shown 4. **Code Style Guidelines** 🏆 - CLAUDE_TEMPLATE.md provides exceptional detail - Real-world examples throughout - Technology-agnostic patterns 5. **Discovery and Description Writing** 🏆 - Strong guidance on writing descriptions - Good vs poor examples - Trigger keyword emphasis --- ## Comparison to Official Documentation ### Areas Where Templates Exceed Official Docs 1. **MCP Server Integration** - Templates provide much more detail than official docs - Clear persistent vs temporary storage guidance - Practical use cases 2. **Code Style Standards** - CLAUDE_TEMPLATE.md is far more comprehensive - Production-ready patterns - Team workflow integration 3. **Examples and Use Cases** - Templates provide significantly more examples - Multiple scenarios covered - Real-world patterns ### Areas Where Official Docs Have More Detail 1. **Frontmatter Configuration** - Official docs clearly list all frontmatter options - Templates missing `model` field documentation - Tool inheritance explained in official docs 2. **Extended Thinking** - Official docs explain thinking budget levels - Templates have no mention of this capability 3. **Invocation Mechanisms** - Official docs clearly distinguish model-invoked vs user-invoked - Templates don't emphasize this critical difference --- ## Action Items for Template Updates ### Commands Template - [ ] Add `model` frontmatter field with examples - [ ] Expand `allowed-tools` with pattern matching guide - [ ] Add extended thinking section - [ ] Add tool inheritance explanation - [ ] Add model selection strategy table ### Agent Template - [ ] Add complete frontmatter section with all options - [ ] Add `allowed-tools` field with examples - [ ] Add `model` field with selection guidance - [ ] Add "How This Agent is Invoked" section - [ ] Clarify user vs project agent storage - [ ] Add model-invoked vs user-invoked explanation ### Skills Template - [ ] Add `model` frontmatter field - [ ] Strengthen "model-invoked" emphasis - [ ] Add required SKILL.md naming convention - [ ] Expand tool pattern examples - [ ] Add model selection strategy - [ ] Add discovery optimization section ### Output Styles Template - [ ] Add model configuration guidance (if supported) - [ ] Clarify all supported frontmatter options - [ ] Add technical details of prompt replacement - [ ] Expand model selection recommendations ### CLAUDE.md Template - [ ] Add extended thinking section - [ ] Add comprehensive hooks section - [ ] Add MCP servers section - [ ] Add model selection guidance - [ ] Add extended thinking use cases --- ## Conclusion The templates provide an **excellent foundation** with particularly strong coverage of: - MCP server integration - Argument handling and file references - Code style and team workflows - Discovery and description writing However, they are **missing critical capabilities** from the official documentation: - `model` frontmatter configuration (all templates) - Extended thinking integration (all templates) - Comprehensive `allowed-tools` patterns (commands, agents, skills) - Invocation mechanism clarity (agents, skills) **Recommendation**: Prioritize adding the "Critical" items listed above to bring templates to 95%+ completeness with official Claude Code capabilities. --- **Analysis performed by**: Code Reviewer Agent **Date**: 2025-10-20 **Templates Reviewed**: 5 **Official Docs Consulted**: docs.claude.com **Missing Capabilities Identified**: 15+ **Well-Implemented Features**: 20+
