Skill Forge

Generate complete, production-ready skills for any domain with optimal architecture and all required resources.

Core Capability

Skill Forge transforms skill requests into complete, validated, distributable .skill packages by:

•Intelligent requirement analysis - Extract skill purpose, triggers, workflows, and resource needs
•Optimal architecture design - Determine appropriate freedom levels, resource structure, and patterns
•Complete resource generation - Create scripts, references, assets, and comprehensive SKILL.md
•Automatic validation - Ensure all requirements met before packaging
•Distributable packaging - Generate ready-to-use .skill files

When to Use Skill Forge

Trigger when users request:

•"Make me a skill for [domain/task]"
•"Create a skill that does [functionality]"
•"I need a skill to help with [workflow]"
•"Generate a [topic] skill"
•Any request to create, design, or improve a skill

Skill Generation Workflow

Phase 1: Understand Requirements

Goal: Extract clear examples of how the skill will be used.

Ask targeted questions to understand:

•Functionality: What should this skill do? What are the main tasks?
•Triggers: What would a user say to invoke this skill?
•Context: Who will use it? What's their expertise level?
•Examples: "Can you give 3-5 concrete examples of queries this skill should handle?"
•Constraints: Any specific requirements, formats, or limitations?

Avoid overwhelming users - Ask 2-3 questions max per message, prioritize most important.

Conclude when: You have 3-5 concrete usage examples and understand the scope.

Phase 2: Analyze Architecture

Goal: Design optimal skill structure and identify all required resources.

For each concrete example, determine:

•
Workflow complexity:
- •Simple (single operation) → Concise instructions
- •Medium (multi-step) → Sequential workflow with checkpoints
- •Complex (branching logic) → Conditional workflow with decision trees
•
Required resources:
- •Scripts (scripts/): Repeated code, deterministic operations, fragile processes
- •References (references/): Schemas, API docs, domain knowledge, examples
- •Assets (assets/): Templates, boilerplate, images, fonts, sample files
•
Freedom level:
- •High freedom: Multiple valid approaches, context-dependent decisions
- •Medium freedom: Preferred patterns with some flexibility
- •Low freedom: Fragile operations requiring specific sequences
•
Progressive disclosure needs:
- •Core workflow in SKILL.md (<500 lines)
- •Detailed references in separate files
- •Optional resources loaded as needed

Output: Complete architectural plan listing all resources to generate.

Phase 3: Generate Skill Resources

Order of generation:

•Create bundled resources first (scripts/references/assets)
•Write SKILL.md last (after understanding all resources)

Generate Scripts (`scripts/`)

Create Python/Bash scripts for:

•Repeated operations (same code written multiple times)
•Deterministic tasks requiring exact execution
•Complex algorithms or data processing
•Fragile operations prone to errors

Script requirements:

•Executable and tested
•Clear docstrings and comments
•Proper error handling
•Command-line friendly (argparse for Python)

Example: For PDF rotation skill, create scripts/rotate_pdf.py

Generate References (`references/`)

Create reference files for:

•Database schemas and relationships
•API documentation and endpoints
•Domain-specific knowledge
•Detailed examples and patterns
•Company policies or guidelines

Reference file principles:

•Structured and scannable (headers, lists, tables)
•Include search keywords for easy grep
•Avoid duplication with SKILL.md
•Load only when needed

Example: For BigQuery skill, create references/schema.md with table schemas

Generate Assets (`assets/`)

Create asset files for:

•Templates to copy or modify
•Boilerplate code structures
•Brand assets (logos, fonts, colors)
•Sample documents or files
•Static resources used in output

Asset principles:

•Not loaded into context
•Used in final output
•Ready to copy/modify
•Organized by type

Example: For webapp skill, create assets/react-template/ with boilerplate React project

Generate SKILL.md

Create comprehensive SKILL.md with:

Frontmatter (YAML):

yaml

---
name: skill-name
description: Complete description including WHAT the skill does and WHEN to use it. Include all triggers, contexts, and use cases here since body loads only after triggering. Examples: "Use when user requests X", "Triggers include Y", "Handles Z tasks".
---

Body (Markdown):

•Overview - Brief capability summary
•Core workflow - Main process or steps
•Resource usage - How to use bundled scripts/references/assets
•Examples - Concrete input/output demonstrations
•Advanced patterns - Optional techniques or variations
•References to external files - When to load each reference

Writing principles:

•Concise (challenge every paragraph's token cost)
•Imperative/infinitive form ("Use X" not "You should use X")
•Examples over explanations
•Keep under 500 lines (split to references if longer)
•Assume Claude is smart (don't over-explain)

Progressive disclosure:

•Essential workflow in SKILL.md
•Detailed guidance in references
•Variants in separate files

Phase 4: Validate & Package

•
Run validation using scripts/quick_validate.py:
- •YAML frontmatter format
- •Required name and description fields
- •Skill naming conventions
- •Directory structure
- •Description completeness
- •Resource references
•
Package skill using scripts/package_skill.py:
- •Creates skill-name.skill file (zip with .skill extension)
- •Includes all files and directory structure
- •Ready for distribution
•
Provide to user:
- •Link to download .skill file
- •Brief usage instructions
- •Trigger phrase examples

Best Practices by Skill Type

Technical Integration Skills

Examples: API clients, file format processors, database tools

Key resources:

•scripts/ for API wrappers and processing logic
•references/ for API documentation, schemas, endpoints
•Minimal SKILL.md focused on workflow

Pattern:

markdown

# API Integration Workflow
1. Authenticate (use scripts/auth.py)
2. Fetch data (use scripts/fetch.py)
3. Process response (see references/schema.md)
4. Transform output

Domain Expertise Skills

Examples: Finance, legal, medical, industry-specific

Key resources:

•references/ for domain knowledge, terminology, frameworks
•assets/ for templates and examples
•Detailed SKILL.md with decision trees

Pattern:

markdown

# Domain Analysis Workflow
1. Identify document type (see references/types.md)
2. Apply framework (see references/framework.md)
3. Generate output using template (assets/template.docx)

Multi-Step Workflow Skills

Examples: Report generation, data pipelines, content creation

Key resources:

•scripts/ for each major step
•references/ for examples and quality standards
•Clear sequential workflow in SKILL.md

Pattern:

markdown

# Workflow Steps
1. Gather inputs (run scripts/gather.py)
2. Process data (run scripts/process.py)
3. Generate output (run scripts/generate.py)
4. Validate result (run scripts/validate.py)

Creative Content Skills

Examples: Writing, design, content generation

Key resources:

•references/ for style guides, examples, voice/tone
•assets/ for templates, brand assets
•Template pattern in SKILL.md

Pattern:

markdown

# Content Creation
Follow brand voice in references/voice.md
Use templates from assets/templates/
Examples in references/examples.md

Advanced Patterns

Multi-Framework Skills

When skill supports multiple frameworks/variations:

SKILL.md:

markdown

# Core Workflow
1. Choose framework (see references/frameworks.md)
2. Follow framework-specific guide

## Framework Selection
- React → See references/react.md
- Vue → See references/vue.md
- Angular → See references/angular.md

Each framework guide in separate reference file.

Conditional Workflows

For branching logic:

markdown

# Workflow
1. Determine task type:
   **Creating new?** → Creation workflow (below)
   **Modifying existing?** → Modification workflow (below)
   **Analyzing?** → Analysis workflow (below)

## Creation Workflow
[Steps for creation]

## Modification Workflow
[Steps for modification]

## Analysis Workflow
[Steps for analysis]

Template-Based Skills

For consistent output:

markdown

# Output Format

ALWAYS use this structure:

# [Title]
## Executive Summary
[One paragraph]

## Key Findings
- Finding 1 with data
- Finding 2 with data

## Recommendations
1. Actionable recommendation
2. Actionable recommendation

Use "ALWAYS" for strict requirements, "suggested format" for flexible guidance.

Common Anti-Patterns to Avoid

❌ Don't:

•Create README.md, CHANGELOG.md, or auxiliary docs
•Duplicate content between SKILL.md and references
•Over-explain basic concepts Claude already knows
•Use first-person language ("I will" or "You should")
•Create single-purpose skills that could be general-purpose
•Include setup instructions or testing procedures
•Make SKILL.md longer than 500 lines without splitting

✅ Do:

•Keep SKILL.md focused on essential workflow
•Use imperative form ("Use", "Run", "Follow")
•Trust Claude's intelligence
•Split detailed content to references
•Design for reusability across contexts
•Focus on procedural knowledge Claude doesn't have
•Test all scripts before finalizing

Iteration & Improvement

After generating a skill:

•Test with real queries - Try actual use cases
•Identify friction points - Where does Claude struggle?
•Analyze root cause - Missing resource? Unclear instructions? Wrong pattern?
•Update resources - Modify scripts, references, or SKILL.md
•Re-validate and package - Ensure improvements work
•Document learnings - Note patterns for future skills

Using Skill Forge Effectively

For users:

•Provide 3-5 concrete usage examples
•Specify expertise level of end users
•Share any existing templates, docs, or code
•Indicate must-haves vs nice-to-haves

For Skill Forge:

•Ask targeted questions (2-3 max per message)
•Generate complete resources, not just outlines
•Test scripts before including them
•Validate before packaging
•Provide clear usage instructions with .skill file

Skill Generation Speed Patterns

Quick skills (10 min):

•Simple domain knowledge
•No scripts needed
•Light references
•Template-based output

Medium skills (30 min):

•2-4 scripts
•Multiple references
•Asset templates
•Multi-step workflows

Complex skills (60+ min):

•5+ scripts
•Extensive references
•Asset libraries
•Conditional workflows
•Framework variations

Set expectations based on complexity.

Script Tools

Use the initialization and packaging scripts from skill-creator:

Initialize new skill:

bash

/mnt/skills/examples/skill-creator/scripts/init_skill.py <skill-name> --path <output-dir>

Validate skill:

bash

/mnt/skills/examples/skill-creator/scripts/quick_validate.py <skill-directory>

Package skill:

bash

/mnt/skills/examples/skill-creator/scripts/package_skill.py <skill-directory> [output-dir]

Example: Complete Skill Generation

User request: "Make me a skill for analyzing financial reports"

Phase 1: Requirements Q: "What types of financial reports? (10-K, earnings, balance sheets, all?)" Q: "What analysis do you need? (ratios, trends, comparisons, recommendations?)" Q: "Any specific output format requirements?"

Phase 2: Architecture

•Workflow: Sequential (load → analyze → generate report)
•Scripts: None needed (analysis is context-dependent)
•References: references/financial-ratios.md, references/analysis-framework.md, references/report-examples.md
•Assets: assets/report-template.md
•Freedom: High (analysis varies by report type)

Phase 3: Generate

•Create references/financial-ratios.md with ratio definitions and formulas
•Create references/analysis-framework.md with step-by-step analysis approach
•Create references/report-examples.md with sample analyses
•Create assets/report-template.md with output structure
•Write SKILL.md with workflow and resource references

Phase 4: Validate & Package

•Run quick_validate.py → Pass
•Run package_skill.py → Generate financial-analysis.skill
•Provide download link and usage examples

Summary

Skill Forge generates complete, production-ready skills by:

•Understanding requirements through targeted questions
•Designing optimal architecture based on patterns
•Generating all resources (scripts, references, assets)
•Creating comprehensive SKILL.md
•Validating and packaging for distribution

Every generated skill follows best practices, leverages progressive disclosure, and focuses on the essential procedural knowledge that makes Claude effective at specialized tasks.
