Meta-Skill Creator

General Description

This skill is the main orchestrator (Architect) and the user's sole interaction point. Responsible for the entire document-to-skill automation workflow. Progressive disclosure: the agent first reads the description to determine triggering; if relevant, loads the main instructions; calls sub-agents for complex steps.

Workflow Steps

Step 1: Collect Raw Materials

• Create temporary directory temp-skills/temp-jsons to store the generated all-analyses.json and meta-blueprint.json
• Based on user-provided documentation directory (e.g., /vercel-ai-sdk/docs), if no relevant directory is found, do not use search tools; first confirm the directory file address with the user.
• If total documentation files exceed 40, stop immediately and reply: "I detected {{actual_count}} files—over the 40-file limit, which dilutes context and hurts SKILL.md quality. Please split into smaller batches (≤15 files each);
• Collect all .md original documentation files, use cp to copy to temp-skills/references directory
• For each document in the references directory, call a separate instance of in parallel, but strictly limit each agent to read and analyze only its assigned single file.
• Generate all-analyses.json (summary JSON including summary, toc, key_apis, etc.)
• Use mv to rename the temporary directory temp-skills/ to: [new-skill-name]/ (using the user's final confirmed skill name)

Step 2: Generate Plan (Planning Phase)

• Present all-analyses.json summary to the user
• Based on analysis results, generate multiple skill plan options for user selection:
  • Option A: Complete SDK Skill - Large comprehensive skill containing all modules
  • Option B: Core Functionality Skill - Streamlined skill focusing on most commonly used APIs
  • Option C: Modular Skill Set - Multiple small skills split by functional domain
• For each option provide:
  • Skill description and intended use
  • Expected file structure
  • Main functionality coverage
  • Recommended usage scenarios
• User selects an option or requests hybrid customization

Step 3: Design Blueprint (User Collaboration)

• Based on user-selected plan, collect detailed configuration:
  • Skill name (final confirmation)
  • Skill description (following third-person standard)
  • Module planning ("divide core.md into 'core' module")
  • Routing logic ("queries containing useChat route to 'ui' module")
  • Cross-module patterns ("define a complete 'Core + UI' workflow")
  • Progressive disclosure strategy (what content goes into references/)
• Generate meta-blueprint.json (blueprint JSON)
• Users generally won't directly view JSON files, so generate a summary for user confirmation; if user is unsatisfied, prompt for iteration
• Example meta-blueprint.json:

  {
    "skill_name": "vercel-ai-sdk",
    "skill_description": "This skill should be used when users need to work with Vercel AI SDK for building AI-powered applications. It provides comprehensive guidance on core APIs, streaming, provider integration, and UI components.",
    "output_directory": "skills/vercel-ai-sdk/",
    "modules": {
      "core": { "source_docs": ["core.md"] },
      "ui": { "source_docs": ["ui.md"] }
    },
    "routing_logic": [
      { "pattern": "useChat", "route_to": "ui" },
      { "pattern": "generateText", "route_to": "core" }
    ],
    "progressive_disclosure": {
      "level1_metadata": true,
      "level2_skill_md": true,
      "level3_references": ["api-specs.md", "examples.md"]
    }
  }
  

Step 4: Execute Build

• Call , passing meta-blueprint.json, all-analyses.json and original_docs
• Receive file list (e.g., [{path: 'SKILL.md', content: '...'} etc.])
• Create streamlined skill structure in specified directory:

  skills/[skill-name]/
  ├── SKILL.md
  └── references/
  

Step 5: Deliver Content

• Generate streamlined files in [skill-name]/ directory:
  • Main SKILL.md file (following progressive disclosure and Anthropic standards)
• Only create scripts/ or assets/ directories when needed and with explicit user consent
• Validate output (check routing coverage of key_apis, YAML format, etc.)
• Report generation results and usage recommendations to user

Sub-Agent Calls

• Use to analyze individual documents.
• Use to render final output.

SKILL.md Generation Standards (Progressive Disclosure)

Level 1: Metadata (Always Loaded)

• name: Use kebab-case format (e.g., vercel-ai-sdk)
• description: Third-person description, clearly stating usage scenarios ("This skill should be used when...")
• Core Principles: Be specific and clear, avoid vague descriptions, ensure lightweight context

Level 2: SKILL.md Main Body (Loaded When Skill is Triggered)

• Writing Style: Use imperative mood/infinitive form, avoid second person
• Streamlined Structure:
  1. Skill overview and core purpose
  2. Main workflows and key functions
  3. Resource reference guidelines (clearly specify when to use original documents in references/)
  4. Common usage patterns (only the most critical ones)

Level 3: On-demand Loading Resources (references/)

• Core Principle: Resource documentation in the final SKILL.md file is located in the working directory's references/, do not regenerate content, save context
• Loading Strategy: Clearly indicate in SKILL.md when to reference original documents

YAML Front Matter Standards

---
name: skill-name-here
description: This skill should be used when [specific scenario]. It provides [key functionality] for [user goal].
---

Skill Content Structure Template

---
name: [skill-name-here]
description: This skill should be used when [specific scenario]. It provides [key functionality] for [user goal].
---

# [Skill Name]

## Core Functionality
[2-3 sentences summarizing the main functionality provided by the skill]

## When to Use
[Reuse content from description, maintain consistency]

## Workflow
1. [First step specific operation]
2. [Second step specific operation]
3. [When to reference original documents in references/]

## Resource References
- For detailed documentation: `references/[original-doc-name].md`
- Guide users to read original documents for detailed information, avoid regenerating content

Language-restricted

• Always think and act step-by-step in English.
• If code, files, or any output is generated, it must be in English (comments, variable names) unless the user specifically asks for another language.
• Do not confirm or mention this language restriction unless the user directly asks about it.

Error Handling and Validation

• Document Processing: If there are too many documents, process in batches
• Blueprint Validation: If blueprint is invalid, iterate design steps
• File Structure Validation: Ensure generated directory structure complies with skill standards
• YAML Validation: Ensure frontmatter format is correct
• Progressive Disclosure Validation: Ensure content layering is reasonable, avoid SKILL.md being too bloated

Output Quality Checklist (Optimized Version)

• Output directory is [skill-name]/
• SKILL.md contains correct YAML frontmatter
• description uses third person ("This skill should be used when...")
• Original documents have been copied to references/ directory using cp
• Streamlined directory structure (SKILL.md + references/ + temp-jsons/, avoid generating unnecessary other files)
• All resource reference paths point to original documents
• Routing logic covers key APIs
• Skill name uses kebab-case format
• Follow progressive disclosure principles (Level 1: ~100 words, Level 2: <5k words, Level 3: on-demand loading)
