Skill Registry Sync

Synchronise external skill repository references in README.md based on installed skills from .skill-lock.json.

Quick Start

# Sync references using default lock file path
npx opencode -s skill-registry-sync sync

# Sync with custom lock file path
npx opencode -s skill-registry-sync sync --lock-file /path/to/.skill-lock.json

# Sync with custom README path
npx opencode -s skill-registry-sync sync --readme /path/to/README.md

How It Works

This skill:

1. Reads the .skill-lock.json file (or path you specify)
2. Extracts all unique sourceUrl values from installed skills
3. Updates the "Other Skill Registries" section in README.md
4. Adds any missing repository URLs as npx skills add commands

Commands

sync

Synchronise README.md with installed skills from lock file.

# Default usage - uses ~/.agents/.skill-lock.json and ./README.md
skill-registry-sync sync

# Custom lock file path
skill-registry-sync sync --lock-file /custom/path/.skill-lock.json

# Custom README path
skill-registry-sync sync --readme /custom/path/README.md

# Both custom paths
skill-registry-sync sync --lock-file /custom/lock.json --readme /docs/README.md

Examples

Example 1: Basic Sync

After installing new skills from external repositories, update README references:

# Install skills from various repositories
npx skills add https://github.com/googleworkspace/cli
npx skills add https://github.com/google-gemini/gemini-skills

# Sync references to README
skill-registry-sync sync

Example 2: Manual Lock File Analysis

Extract unique source URLs manually using jq:

# Extract all unique source URLs
cat ~/.agents/.skill-lock.json | jq -r '.skills[].sourceUrl' | sort -u

# Count skills per source
cat ~/.agents/.skill-lock.json | jq -r '.skills[].source' | sort | uniq -c

# Get skills from specific source
cat ~/.agents/.skill-lock.json | jq -r '.skills | to_entries[] | select(.value.source == "googleworkspace/cli") | .key'

Implementation

Using jq to Parse Lock File

The skill uses the jq-tooling skill to parse .skill-lock.json:

# Extract unique source URLs
cat ~/.agents/.skill-lock.json | jq -r '.skills[].sourceUrl' | sort -u

# Output format:
# https://github.com/googleworkspace/cli.git
# https://github.com/google-gemini/gemini-skills.git
# https://github.com/google-gemini/gemini-cli.git
# https://github.com/google-labs-code/stitch-skills.git
# https://github.com/vercel-labs/skills.git

README.md Section Format

The skill updates the "Other Skill Registries" section:

### Other Skill Registries

Expand your agent's toolkit with these supplementary skill collections:
- 📦 `npx skills add https://github.com/google-gemini/gemini-skills`
- ⚛️ `npx skills add https://github.com/google-labs-code/stitch-skills --skill react:components`
- 🛠️ `npx skills add https://github.com/google-gemini/gemini-cli`
- 🏢 `npx skills add https://github.com/googleworkspace/cli`
- 📦 `npx skills add https://github.com/vercel-labs/skills`

Common Workflows

Workflow 1: After Installing New Skills

# 1. Install new skills from external repo
npx skills add https://github.com/example/new-skills-repo

# 2. Sync references to README
skill-registry-sync sync

# 3. Review changes
git diff README.md

# 4. Commit updates
git add README.md && git commit -m "docs: add new skill registry reference"

Workflow 2: Audit External Dependencies

# List all external skill sources
cat ~/.agents/.skill-lock.json | jq -r '.skills[].sourceUrl' | sort -u

# Identify which skills come from external repos (not local)
cat ~/.agents/.skill-lock.json | jq -r '.skills | to_entries[] | select(.value.source != "benjaminwestern/google-engineer-skills") | [.key, .value.source] | @tsv'

Workflow 3: Generate Custom Reference Documentation

# Create a custom markdown file with all skill sources
cat ~/.agents/.skill-lock.json | jq -r '
  [.skills[].sourceUrl] | unique |
  "## External Skill Registries\n\n" +
  (map("- `npx skills add " + . | rtrimstr(".git") + "`") | join("\n"))
' > SKILL_SOURCES.md

Tips and Best Practices

Run After Skill Installation

Always sync after installing skills from new repositories to keep documentation accurate:

npx skills add https://github.com/org/new-skills
skill-registry-sync sync

Verify Before Committing

Review changes before committing:

skill-registry-sync sync
git diff README.md

Handle Multiple Lock Files

If you have multiple environments or configurations:

# Production environment
skill-registry-sync sync --lock-file ~/.agents/prod/.skill-lock.json --readme README.prod.md

# Development environment
skill-registry-sync sync --lock-file ~/.agents/dev/.skill-lock.json --readme README.dev.md

Ignore Local Skills

The skill automatically filters out local skills (from the current repository) and only includes external registries in the references section.

Troubleshooting

Lock file not found

# Specify correct path
skill-registry-sync sync --lock-file /correct/path/.skill-lock.json

No changes detected

If no external skills are installed, the section will remain unchanged. Install some external skills first:

npx skills add https://github.com/googleworkspace/cli
skill-registry-sync sync

Duplicate entries

The skill automatically deduplicates URLs. If you see duplicates, ensure you're using the latest version.
