Skills Sync

Skills Sync

Overview

Synchronizes AI agent skills from local directories and Git repositories, generating .cursor/rules/skills.mdc for Cursor IDE integration.

Usage

First time setup (installs uv if needed, then installs skills-sync as a tool):

python3 .claude/skills/skills-sync/scripts/skills_sync.py

Subsequent runs:

skills-sync

The script auto-detects the project root by walking up the directory tree.

Skill Locations (Precedence Order)

Higher precedence locations override skills with the same name from lower locations.

Repository Configuration

Place repos.txt in any skill directory to sync skills from Git repositories:

https://github.com/anthropics/skills
https://github.com/your-org/your-skills-repo
# Comments start with #

The script checks all four skill locations for repos.txt files and deduplicates URLs.

Repository Skill Extraction

Skills are extracted ONLY from .cortex/skills/*/SKILL.md and .claude/skills/*/SKILL.md paths within repositories. Extracted skills are placed in ~/.snowflake/cortex/skills/ with a repo prefix (e.g., skills-dbt-core/).

Managing Repositories

Add Repository: Add URL to repos.txt, run skills-sync

Remove Repository: Delete URL from repos.txt, run skills-sync, optionally delete extracted skills from ~/.snowflake/cortex/skills/<repo>-<skill>/

Output

The script generates .cursor/rules/skills.mdc containing <available_skills> XML that Cursor loads automatically for all AI interactions.

Sync Process

1. Read repos.txt from all locations, deduplicate URLs
2. Clone/update repositories to ~/.snowflake/.cache/repos/
3. Extract skills to ~/.snowflake/cortex/skills/ with repo prefix
4. Scan all four skill locations with precedence rules
5. Validate skills using Agent Skills CLI
6. Generate .cursor/rules/skills.mdc with embedded XML
7. Clean up old marker-delimited sections from AGENTS.md

Requirements

• Python 3.8+
• uv (auto-installed when running as script)
• Git (auto-installed if missing)

When run as a Python script, it auto-installs uv, then installs itself as a uv tool. Git is auto-installed if missing using the appropriate method for your platform.

Troubleshooting

Skills not appearing: Verify SKILL.md exists in immediate child directory with valid frontmatter:

---
name: my-skill
description: What this skill does and when to use it
