This skill should be used when the user asks to "analyze this framework's API", "outside-in outline for X", "API-first learning plan", "create a learning outline for X", "trace the public API", "analyze the API surface", "api-blueprint", or any request to map a Java framework's API surface for outside-in reimplementation. Analyzes a Java framework's source code and produces an API-first learning outline (api-outline.md) that maps the public API surface, traces each capability inward through implementation layers, generates ASCII call-chain diagrams, and creates a buildable project skeleton. --- # API Blueprint — API-First Learning Outline ## Philosophy: Outside-In, API-First The fastest way to learn a framework and confidently contribute to it is to start where the **user** starts — the public API. Instead of hunting for the framework's internal "heart" and building outward (v1 approach), this skill: 1. **Identifies the API surface** — the classes, interfaces, and methods that framework users actually import and call in their application code 2. **Organizes features as vertical slices** — each feature represents one API capability, traced from the public method all the way down through internal layers 3. **Orders by usage tier** — most commonly used APIs first, power-user/advanced APIs last
Skill files are scattered across GitHub and communities, difficult to search, and hard to evaluate. SkillWink organizes open-source skills into a searchable, filterable library you can directly download and use.
We provide keyword search, version updates, multi-metric ranking (downloads / likes / comments / updates), and open SKILL.md standards. You can also discuss usage and improvements on skill detail pages.
Sort by downloads/likes/comments/updated to find higher-quality skills.
4. Which import methods are supported?
Upload archive: .zip / .skill (recommended)
Upload skills folder
Import from GitHub repository
Note: file size for all methods should be within 10MB.
5. How to use in Claude / Codex?
Typical paths (may vary by local setup):
Claude Code:~/.claude/skills/
Codex CLI:~/.codex/skills/
One SKILL.md can usually be reused across tools.
6. Can one skill be shared across tools?
Yes. Most skills are standardized docs + assets, so they can be reused where format is supported.
Example: retrieval + writing + automation scripts as one workflow.
7. Are these skills safe to use?
Some skills come from public GitHub repositories and some are uploaded by SkillWink creators. Always review code before installing and own your security decisions.
8. Why does it not work after import?
Most common reasons:
Wrong folder path or nested one level too deep
Invalid/incomplete SKILL.md fields or format
Dependencies missing (Python/Node/CLI)
Tool has not reloaded skills yet
9. Does SkillWink include duplicates/low-quality skills?
We try to avoid that. Use ranking + comments to surface better skills:
