Making ANY Software Skill-Native
The meta-skill that generates production-ready Skills for AI agent platforms.
Quick Start • Pipeline • Platforms • Architecture • Examples • Attribution
One target in, production-ready Skills out.
SkillAnything is a Skill that generates Skills. Give it any target -- a CLI tool, REST API, Python library, workflow, or web service -- and it runs a fully automated 7-phase pipeline:
Target: "jq"

[Analyze] -> [Design] -> [Implement] -> [Test] -> [Benchmark] -> [Optimize] -> [Package]

└── generic/
No manual prompt engineering. No copy-paste between platforms. Just tell it what you want a skill for.
# Claude Code git clone https://github.com/AgentSkillOS/SkillAnything.git ~/.claude/skills/skill-anything # OpenClaw git clone https://github.com/AgentSkillOS/SkillAnything.git ~/.openclaw/skills/skill-anything # Codex git clone https://github.com/AgentSkillOS/SkillAnything.git ~/.codex/skills/skill-anything
In Claude Code, just say:
> Create a skill for the httpie CLI tool
> Generate a multi-platform skill for the Stripe API
> Turn this data pipeline workflow into a skill
SkillAnything handles the rest.
# Phase 1: Analyze a target python -m scripts.analyze_target --target "jq" --output analysis.json # Phase 2: Design architecture python -m scripts.design_skill --analysis analysis.json --output architecture.json # Phase 3: Scaffold skill python -m scripts.init_skill my-skill --template cli --output ./out # Phase 4: Generate test cases python -m scripts.generate_tests --analysis analysis.json --skill-path ./out/my-skill # Phase 5: Run evaluation python -m scripts.run_eval --eval-set evals.json --skill-path ./out/my-skill # Phase 6: Optimize description python -m scripts.run_loop --eval-set trigger-evals.json --skill-path ./out/my-skill --model claude-sonnet-4-20250514 # Phase 7: Package for all platforms python -m scripts.package_multiplatform ./out/my-skill --platforms claude-code,openclaw,codex
Inspired by CLI-Anything's methodology, adapted for Skill generation:
| Phase | Name | What It Does | Output |
|---|---|---|---|
| 1 | Analyze | Auto-detect target type, extract capabilities | analysis.json |
| 2 | Design | Map capabilities to skill architecture | architecture.json |
| 3 | Implement | Generate SKILL.md + scripts + references | Complete skill directory |
| 4 | Test Plan | Auto-generate eval cases + trigger queries | evals.json |
| 5 | Evaluate | Benchmark with/without skill, grade results | benchmark.json |
| 6 | Optimize | Improve description via train/test loop | Optimized SKILL.md |
| 7 | Package | Multi-platform distribution packages | dist/ |
| Target Type | Detection Method | Example |
|---|---|---|
| CLI Tool | which <name> + --help parsing |
jq, httpie, ffmpeg |
| REST API | URL with OpenAPI/Swagger spec | Stripe API, GitHub API |
| Library | Package name via pip/npm | pandas, lodash |
| Workflow | Step-by-step description | ETL pipeline, CI/CD flow |
| Service | URL with web docs | Slack, Notion |

> Create a skill for the jq CLI tool
Phase 1: Analyzing jq... detected as CLI tool (confidence: 0.95)
Phase 2: Designing skill architecture... tool-augmentation pattern
Phase 3: Generating SKILL.md + 2 scripts + 1 reference
Phase 4: Created 5 test cases + 20 trigger queries
Phase 5: Benchmark: 87% pass rate (vs 42% baseline)
Phase 6: Description optimized: 18/20 trigger accuracy
Phase 7: Packaged for claude-code, openclaw, codex, generic
Done! Skill at: sa-workspace/dist/
> Generate a skill for the Stripe API, focus on payments
Phase 1: Fetching Stripe OpenAPI spec... 247 endpoints found
Phase 2: Focusing on payment_intents, customers, charges
Phase 3: Generated SKILL.md with auth setup + endpoint references
...
> Turn this into a skill: fetch from Postgres, clean with pandas, upload to S3
Phase 1: Detected workflow with 3 steps
Phase 2: workflow-orchestrator pattern, 3 dependencies
Phase 3: Step-by-step SKILL.md with error handling guidance
...
Edit config.yaml:
pipeline: auto_mode: true # Full automation or interactive skip_eval: false # Skip phases 5-6 for rapid prototyping platforms: enabled: [claude-code, openclaw, codex, generic] primary: claude-code eval: max_optimization_iterations: 5 runs_per_query: 3 obfuscation: enabled: false # PyArmor protection for core scripts
SkillAnything supports code obfuscation for commercial distribution:
# Obfuscate original scripts (Apache 2.0 derived files are excluded) python -m scripts.obfuscate --config config.yaml # Output: dist-protected/ with PyArmor-protected core + readable adapted scripts
| Category | Files | Protection |
|---|---|---|
| SkillAnything Original | 6 scripts | PyArmor obfuscated |
| Anthropic Adapted | 9 scripts | Source (Apache 2.0 requires it) |
| Agent Instructions | 7 .md files | Readable (required by agents) |
Built on the shoulders of giants:
| Project | License | What We Used |
|---|---|---|
| CLI-Anything | MIT | 7-phase pipeline methodology |
| Dazhuang Skill Creator | Apache 2.0 | Project structure pattern |
| Anthropic Skill Creator | Apache 2.0 | Eval/benchmark system, agent instructions |
