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):

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

Subsequent runs:

bash
skills-sync

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

Skill Locations (Precedence Order)

Priority Location Type
1 (highest) $PROJECT/.cortex/skills/ Project
2 $PROJECT/.claude/skills/ Project
3 ~/.snowflake/cortex/skills/ Global
4 (lowest) ~/.claude/skills/ Global

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:

text
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:
