Rules for creating and editing vibecosystem skills.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Skill Development Rules

## Skill Directory Structure

Each skill lives in its own directory under `skills/`:

```
skills/
  coding-standards/
    SKILL.md      # Skill metadata + trigger description
    prompt.md     # Full skill content
```

## SKILL.md Format

```yaml
---
name: skill-name
description: When and why to use this skill. Used for auto-discovery.
---
```

Followed by the skill content in Markdown.

## prompt.md Format

The full prompt/knowledge content. No frontmatter needed.

## Naming Conventions
- Directory name: `kebab-case` (e.g., `coding-standards`)
- SKILL.md name field: same as directory name
- Description: explains WHEN to trigger, not just WHAT it does

## Quality Rules
- Description must clearly indicate trigger conditions
- Content should be actionable, not theoretical
- Include code examples where applicable
- Keep skills focused on one domain/topic
- Cross-reference related skills in content

How to install

The exact contents, by fingerprint
mdr add vibeeval/vibecosystem/.cursor/rules/skill-development.mdc@sha256:0624159981e0d42f

The line at the top of this page pins the label git:20260330.cd5da78, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
