Install Skill Anything
Pick your agent. Every command is ready to paste.
npx skills add AgentSkillOS/SkillAnythingThe open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.
01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads skill-anything when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the skill-anything skill”. In Codex, type $skill-anything.
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:
- Test cases with assertions → graded by
agents/grader.md - Benchmark comparing with-skill vs baseline →
benchmark.json - Description optimization with train/test split → prevents overfitting
- Interactive viewer via
eval-viewer/generate_review.py
The eval loop is optional (skip_eval: true in config) for rapid prototyping.

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-typeoverride - 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

Tips for Skill Anything
- • Start a fresh session after installing so your agent picks up the new skill.
- • If two skills overlap, mention the one you want by name.
Questions about Skill Anything
What does the Skill Anything skill do?
Automatically generate production-ready Skills for any software, API, CLI tool, library, workflow, or service. Use this skill whenever the user wants to create a skill from scratch for a target application, convert an existing tool into an agent-native skill, generate skills for multiple platforms (Claude Code, OpenClaw, Codex), or automate the full skill creation pipeline including analysis, design, implementation,
How do I install Skill Anything?
Run "npx skills add AgentSkillOS/SkillAnything" in your project. The skills CLI installs it for Claude Code, Cursor, Codex and 70+ other agents. In Claude on the web, upload the skill folder as a ZIP under Customize > Skills.
Does Skill Anything work in Cursor and Codex?
Yes. Skill Anything uses the open SKILL.md format, so it works in Claude Code, Claude, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot and other agents that support agent skills.
Is Skill Anything free?
Skill Anything is open source on GitHub under the MIT license. It is free to install; check the license before commercial use.
Who made Skill Anything?
Skill Anything is published by AgentSkillOS in the AgentSkillOS/SkillAnything repository.
