Skill Discovery Workflow for Flutter

Step 1: Search for Available Skills

# Search for Flutter-related skills
npx skills find flutter

# Search for state management
npx skills find "state management"

# Search for specific integrations
npx skills find supabase

Step 2: List Before Installing

# See what's available in a repository
npx skills add vercel-labs/agent-skills --list

# Filter to specific skills
npx skills add some-org/flutter-skills --list

Step 3: Preview Skill Content

When considering a skill:

1. View the source repository
2. Read the SKILL.md file directly on GitHub
3. Assess relevance and quality
4. Check last update date

Step 4: Install Selected Skills

# Install specific Flutter-related skills
npx skills add my-flutter-repo/skills --skill "flutter-testing" --skill "performance-optimization"

# Install to project scope (committed with code)
npx skills add my-flutter-repo/skills --skill "flutter-testing"

# Install globally (available everywhere)
npx skills add my-flutter-repo/skills -g

Step 5: Verify Installation

npx skills ls -a github-copilot

Important: Always Check Current Documentation

⚠️ This skill description is based on

skills

The npm package updates frequently with new features and agent support. When using this skill:

1. Always check the latest documentation:

   • https://www.npmjs.com/package/skills
   • GitHub repo: https://github.com/vercel-labs/skills

2. Verify agent compatibility:

   • New agents are added regularly
   • Agent paths may change
   • Check latest supported agents list

3. Check for new search features:

   • The CLI evolves with new commands
   • Search capabilities expand over time
   • New installation options may be available

4. Review breaking changes:

   • Before major version updates
   • Especially if using in CI/CD pipelines
   • Check release notes on npm

Best Practices

✅ DOs

• Use

  --list

  first to preview available skills before installing
• Search multiple sources - Not all skills are in one repository
• Keep skills updated - Run

  npx skills update

  regularly
• Organize by scope - Use project scope for team-specific skills, global for personal tools
• Version control - Commit symlink information or skill references
• Document reasoning - Note why a skill was installed and what it does

❌ DON'Ts

• Don't install all skills indiscriminately - Clutter reduces clarity
• Don't skip the --list preview - Avoid installing irrelevant skills
• Don't ignore skill sources - Verify repository credibility
• Don't forget to read SKILL.md - Understand what you're installing
• Don't use outdated repositories - Watch for abandoned projects

Troubleshooting

"No skills found"

# Ensure you're searching valid repositories
npx skills add owner/repo --list

# Check for typos in repository name
# Verify repository contains SKILL.md files

Skill not loading in agent

• Verify installation path:

  npx skills ls

• Check agent's skill directory exists
• Ensure SKILL.md has proper YAML frontmatter
• Try reinstalling:

  npx skills add source --skill name -y

Permission errors

# For global installation
npx skills add repo -g

# Or use --copy instead of symlink
npx skills add repo --copy

Conflicting skills

• Skills can have same name across agents
• Use

  -a

  flag to target specific agents
• Remove first if upgrading:

  npx skills remove old-skill

Integration with Flutter Development

Recommended Workflow

1. When starting new project or feature:

   npx skills find flutter

   npx skills find "testing"
   

3. When integrating external services:

   npx skills find supabase
   npx skills find firebase
   npx skills find stripe
   

4. Keep skills current:

   npx skills check
   npx skills update
