SkillAnything

Automatically generate production-ready Skills for any target — software, API, CLI tool, library,

workflow, or web service. SkillAnything runs a 7-phase pipeline that analyzes your target, designs

the skill architecture, implements it, generates test cases, benchmarks performance, optimizes the

description, and packages for multiple agent platforms.

Quick Start

Fully automated (one command):

Give SkillAnything a target and it handles everything:
- "Create a skill for the jq CLI tool"
- "Generate a skill for the Stripe API"
- "Turn this workflow into a multi-platform skill"

The pipeline runs all 7 phases automatically. Results land in sa-workspace/.

The 7-Phase Pipeline

Phase 1: Analyze    → Detect target type, extract capabilities     → analysis.json
Phase 2: Design     → Map capabilities to skill architecture       → architecture.json
Phase 3: Implement  → Generate SKILL.md + scripts + references     → complete skill directory
Phase 4: Test Plan  → Auto-generate eval cases + trigger queries   → evals.json
Phase 5: Evaluate   → Benchmark with/without skill, grade results  → benchmark.json
Phase 6: Optimize   → Improve description via train/test loop      → optimized SKILL.md
Phase 7: Package    → Multi-platform distribution packages         → dist/

See METHODOLOGY.md for the full pipeline specification.

Usage Modes

Auto Mode (default)

Runs all 7 phases end-to-end. Provide the target and SkillAnything does the rest:

Target: "the httpie CLI tool"
→ Analyzes httpie --help output, designs command structure, generates skill,
  creates tests, benchmarks, optimizes, packages for 4 platforms

Interactive Mode

Set auto_mode: false in config.yaml. SkillAnything pauses after each phase for review:

• Phase 1 → "Here's what I found about the target. Look right?"
• Phase 2 → "Here's the proposed skill architecture. Any changes?"
• Phase 3 → "Draft skill ready for review."
• ...continues with user feedback at each step

Single Phase Mode

Run any phase independently:

python -m scripts.analyze_target --target "jq" --output analysis.json
python -m scripts.design_skill --analysis analysis.json --output architecture.json
python -m scripts.init_skill my-skill --template cli --output ./out
python -m scripts.generate_tests --analysis analysis.json --skill-path ./out/my-skill
python -m scripts.run_eval --eval-set evals.json --skill-path ./out/my-skill
python -m scripts.run_loop --eval-set trigger-evals.json --skill-path ./out/my-skill --model <model>
python -m scripts.package_multiplatform ./out/my-skill --platforms claude-code,openclaw,codex

Configuration

Edit config.yaml to customize the pipeline. Key settings:

| Setting | Default | Description |

|---------|---------|-------------|

| pipeline.auto_mode | true | Run all phases or pause for review |

| target.type | auto | Force target type: api, cli, library, workflow, service |

| platforms.enabled | all 4 | Which platforms to package for |

| platforms.primary | claude-code | Primary output platform |

| eval.max_optimization_iterations | 5 | Max description optimization rounds |

| obfuscation.enabled | false | Obfuscate original scripts with PyArmor |

See references/schemas.md for the complete configuration schema.

Platform Output

| Platform | Install Path | Package Format |

|----------|-------------|----------------|

| Claude Code | ~/.claude/skills/<name>/ | Directory |

| OpenClaw | ~/.openclaw/skills/<name>/ | Directory |

| Codex | ~/.codex/skills/<name>/ | Directory + openai.yaml |

| Generic | anywhere | .skill zip |

See references/platform-formats.md for platform-specific format details.

Evaluation and Benchmarking

SkillAnything uses the same eval system as the Anthropic skill-creator:

1. Test cases with assertions → graded by agents/grader.md
2. Benchmark comparing with-skill vs baseline → benchmark.json
3. Description optimization with train/test split → prevents overfitting
4. Interactive viewer via eval-viewer/generate_review.py

The eval loop is optional (skip_eval: true in config) for rapid prototyping.

Scripts Reference

Agents

Read these when spawning specialized subagents:

| Agent | Purpose |

|-------|---------|

| agents/analyzer.md | Phase 1: Target analysis instructions |

| agents/designer.md | Phase 2: Skill architecture design |

| agents/implementer.md | Phase 3: Skill content writing |

| agents/grader.md | Phase 5: Eval assertion grading |

| agents/comparator.md | Phase 5: Blind A/B output comparison |

| agents/optimizer.md | Phase 6: Description optimization orchestration |

| agents/packager.md | Phase 7: Multi-platform packaging instructions |

Target Types

SkillAnything auto-detects the target type and adapts its analysis:

| Type | Detection | Analysis Method |

|------|-----------|-----------------|

| API | URL with /api, OpenAPI spec, swagger | Fetch spec, extract endpoints |

| CLI | Executable name, --help output | Run help, parse subcommands |

| Library | Package name, import path | Read docs, parse public API |

| Workflow | Step descriptions, sequence | Parse steps, map data flow |

| Service | URL, web interface | Scrape docs, identify actions |

Troubleshooting

• Phase 1 fails: Target not found or inaccessible → provide --target-type override
• Low eval scores: Description too vague → run Phase 6 optimization
• Platform packaging errors: Missing required fields → check references/platform-formats.md
• PyArmor not found: Install with pip install pyarmor
