Our review
This meta-skill guides users through an adaptive process to create new AI agent skills, from requirements gathering to folder structure and content generation.
Strengths
- Adaptive questioning tailors the skill to specific user needs
- Provides clear file structure templates for both simple and complex skills
- Integrated research step for external APIs ensures accurate implementations
- Builds reusable components like workflows, references, templates, and scripts
Limitations
- Requires familiarity with the recommended skill structure and XML format
- Might be overkill for very simple skills that could be hand-written quickly
- Relies on external tools like Context7 MCP for API research
Use this skill when you need to systematically create a well-structured AI agent skill that may involve multiple workflows or external integrations.
Do not use this skill if you are just making a small one-off instruction or if you are already comfortable writing a SKILL.md by hand.
Security analysis
SafeThe skill describes a legitimate workflow for creating new AI skills, involving directory and file creation via mkdir and cat. There are no destructive commands, data exfiltration, or safety bypasses. The operations are standard and user-intended.
No concerns found
Examples
I want to build a new skill that helps manage Docker containers, images, and compose files. It should include common operations like status checks, logs, and basic troubleshooting.Create a skill for automated code review that checks for security issues, style violations, and provides feedback in pull requests.Help me create a skill that scaffolds new projects with a standard folder structure, configuration files, and initial documentation.Workflow: Create a New Skill
<required_reading> Read these reference files NOW:
- references/recommended-structure.md
- references/skill-structure.md
- references/core-principles.md
- references/use-xml-tags.md </required_reading>
If user provided context (e.g., "build a skill for X"): → Analyze what's stated, what can be inferred, what's unclear → Skip to asking about genuine gaps only
If user just invoked skill without context: → Ask what they want to build
Using question
Ask 2-4 domain-specific questions based on actual gaps. Each question should:
- Have specific options with descriptions
- Focus on scope, complexity, outputs, boundaries
- NOT ask things obvious from context
Example questions:
- "What specific operations should this skill handle?" (with options based on domain)
- "Should this also handle [related thing] or stay focused on [core thing]?"
- "What should the user see when successful?"
Decision Gate
After initial questions, ask: "Ready to proceed with building, or would you like me to ask more questions?"
Options:
- Proceed to building - I have enough context
- Ask more questions - There are more details to clarify
- Let me add details - I want to provide additional context
Step 2: Research Trigger (If External API)
When external service detected, ask using question: "This involves [service name] API. Would you like me to research current endpoints and patterns before building?"
Options:
- Yes, research first - Fetch current documentation for accurate implementation
- No, proceed with general patterns - Use common patterns without specific API research
If research requested:
- Use Context7 MCP to fetch current library documentation
- Or use WebSearch for recent API documentation
- Focus on 2024-2026 sources
- Store findings for use in content generation
Step 3: Decide Structure
Simple skill (single workflow, <200 lines): → Single SKILL.md file with all content
Complex skill (multiple workflows OR domain knowledge): → Router pattern:
skill-name/
├── SKILL.md (router + principles)
├── workflows/ (procedures - FOLLOW)
├── references/ (knowledge - READ)
├── templates/ (output structures - COPY + FILL)
└── scripts/ (reusable code - EXECUTE)
Factors favoring router pattern:
- Multiple distinct user intents (create vs debug vs ship)
- Shared domain knowledge across workflows
- Essential principles that must not be skipped
- Skill likely to grow over time
Consider templates/ when:
- Skill produces consistent output structures (plans, specs, reports)
- Structure matters more than creative generation
Consider scripts/ when:
- Same code runs across invocations (deploy, setup, API calls)
- Operations are error-prone when rewritten each time
See references/recommended-structure.md for templates.
Step 4: Create Directory
mkdir -p ~/.config/opencode/skills/{skill-name}
# If complex:
mkdir -p ~/.config/opencode/skills/{skill-name}/workflows
mkdir -p ~/.config/opencode/skills/{skill-name}/references
# If needed:
mkdir -p ~/.config/opencode/skills/{skill-name}/templates # for output structures
mkdir -p ~/.config/opencode/skills/{skill-name}/scripts # for reusable code
Step 5: Write SKILL.md
Simple skill: Write complete skill file with:
- YAML frontmatter (name, description)
<objective><quick_start>- Content sections with pure XML
<success_criteria>
Complex skill: Write router with:
- YAML frontmatter
<essential_principles>(inline, unavoidable)<intake>(question to ask user)<routing>(maps answers to workflows)<reference_index>and<workflows_index>
Step 6: Write Workflows (if complex)
For each workflow:
<required_reading>
Which references to load for this workflow
</required_reading>
<process>
Step-by-step procedure
</process>
<success_criteria>
How to know this workflow is done
</success_criteria>
Step 7: Write References (if needed)
Domain knowledge that:
- Multiple workflows might need
- Doesn't change based on workflow
- Contains patterns, examples, technical details
Step 8: Validate Structure
Check:
- [ ] YAML frontmatter valid
- [ ] Name matches directory (lowercase-with-hyphens)
- [ ] Description says what it does AND when to use it (third person)
- [ ] No markdown headings (#) in body - use XML tags
- [ ] Required tags present: objective, quick_start, success_criteria
- [ ] All referenced files exist
- [ ] SKILL.md under 500 lines
- [ ] XML tags properly closed
Step 9: Create Slash Command
cat > ~/.config/opencode/commands/{skill-name}.md << 'EOF'
---
description: {Brief description}
argument-hint: [{argument hint}]
allowed-tools: Skill({skill-name})
---
Invoke the {skill-name} skill for: $ARGUMENTS
EOF
Step 10: Test
Invoke the skill and observe:
- Does it ask the right intake question?
- Does it load the right workflow?
- Does the workflow load the right references?
- Does output match expectations?
Iterate based on real usage, not assumptions. </process>
<success_criteria> Skill is complete when:
- [ ] Requirements gathered with appropriate questions
- [ ] API research done if external service involved
- [ ] Directory structure correct
- [ ] SKILL.md has valid frontmatter
- [ ] Essential principles inline (if complex skill)
- [ ] Intake question routes to correct workflow
- [ ] All workflows have required_reading + process + success_criteria
- [ ] References contain reusable domain knowledge
- [ ] Slash command exists and works
- [ ] Tested with real invocation </success_criteria>
