💍 The Ring - Skills Library for AI Agents

Proven engineering practices, enforced through skills.

Ring is a comprehensive skills library and workflow system for AI agents that transforms how AI assistants approach software development. Currently implemented as a Claude Code plugin marketplace with 4 active plugins, 69 skills, and 35 agents (see .claude-plugin/marketplace.json for current versions), the skills themselves are agent-agnostic and can be used with any AI agent system. Ring provides battle-tested patterns, mandatory workflows, and systematic approaches across the entire software delivery value chain.

✨ Why Ring?

Without Ring, AI assistants often:

• Skip tests and jump straight to implementation
• Make changes without understanding root causes
• Claim tasks are complete without verification
• Forget to check for existing solutions
• Repeat known mistakes

Ring solves this by:

• Enforcing proven workflows - Test-driven development, systematic debugging, proper planning
• Providing 69 specialized skills (14 core + 31 dev-team + 18 product planning + 6 technical writing)
• 35 specialized agents - 10 review/planning + 18 developer + 4 product research + 3 technical writing
• Automating skill discovery - Skills load automatically at session start
• Preventing common failures - Built-in anti-patterns and mandatory checklists

🧭 Project Identity

Ring is Lerian-first, open-source-friendly. Design decisions prioritize the Lerian engineering team’s daily needs while keeping the architecture clean and reusable for external adoption. This means:

• Lerian-specific skills stay active — Internal integrations and domain-specific workflows remain in the marketplace because the team uses them
• The architecture is universal — Skills, agents, and the plugin system work with any codebase or team
• Archival is usage-driven — Skills are archived when they stop being used, not because they’re “too specific”

🤖 Specialized Agents

Review & Planning Agents (default plugin):

• ring:code-reviewer - Foundation review (architecture, code quality, design patterns)
• ring:business-logic-reviewer - Correctness review (domain logic, requirements, edge cases)
• ring:security-reviewer - Safety review (vulnerabilities, OWASP, authentication)
• ring:test-reviewer - Test quality review (coverage, edge cases, assertions, test anti-patterns)
• ring:nil-safety-reviewer - Nil/null safety review (traces pointer risks, missing guards, panic paths)
• ring:consequences-reviewer - Ripple effect review (traces how changes propagate beyond modified files - caller chains, consumer contracts, downstream breakage)
• ring:dead-code-reviewer - Dead code review (orphaned code detection, reachability analysis, dead dependency chains)
