builtin internal crush

builtin-skills

Use when creating a new builtin skill for Crush, editing an existing builtin skill (internal/skills/builtin/), or when the user needs to understand how the embedded skill system works. --- # Builtin Skills Crush embeds skills directly into the binary via `internal/skills/builtin/`. These are always available without user configuration. ## How It Works - Each skill lives in `internal/skills/builtin/<skill-name>/SKILL.md`. - The tree is embedded at compile time via `//go:embed builtin/*` in `internal/skills/embed.go`. - `DiscoverBuiltin()` walks the embedded FS, parses each `SKILL.md`, and sets paths with the `crush://skills/` prefix (e.g., `crush://skills/jq/SKILL.md`). - The View tool resolves `crush://` paths from the embedded FS, not disk. - User skills with the same name override builtins (last occurrence wins in `Deduplicate()`). ## Adding a New Builtin Skill 1. Create `internal/skills/builtin/<skill-name>/SKILL.md` with YAML frontmatter (`name`, `description`) and markdown instructions. The directory name must match the `name` field. 2. No extra wiring needed — `//go:embed builtin/*` picks up new directories automatically. 3. Add a test assertion in `TestDiscoverBuiltin` in `internal/skills/skills_test.go` to verify discovery. 4. Build and test: `go build . && go test ./internal/skills/...` ## Existing Builtin Skills | Skill | Directory | Description | | -------------- | ----------------------- | ------------------------------------------ | | `crush-config` | `builtin/crush-config/` | Crush configuration help | | `crush-hooks` | `builtin/crush-hooks/` | Authoring, configuring and debugging hooks | | `jq` | `builtin/jq/` | jq JSON processor usage guide |

Why SkillWink?

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.

Keyword Search Version Updates Multi-Metric Ranking Open Standard Discussion

Quick Start:

Import/download skills (.zip/.skill), then place locally:

~/.claude/skills/ (Claude Code)

~/.codex/skills/ (Codex CLI)

One SKILL.md can be reused across tools.

FAQ

Everything you need to know: what skills are, how they work, how to find/import them, and how to contribute.

1. What are Agent Skills?

A skill is a reusable capability package, usually including SKILL.md (purpose/IO/how-to) and optional scripts/templates/examples.

Think of it as a plugin playbook + resource bundle for AI assistants/toolchains.

2. How do Skills work?

Skills use progressive disclosure: load brief metadata first, load full docs only when needed, then execute by guidance.

This keeps agents lightweight while preserving enough context for complex tasks.

3. How can I quickly find the right skill?

Use these three together:

  • Semantic search: describe your goal in natural language.
  • Multi-filtering: category/tag/author/language/license.
  • 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:

  • Duplicate skills: compare differences (speed/stability/focus)
  • Low quality skills: regularly cleaned up
