💍 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 6 active plugins and 90 skills (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 90 specialized skills (22 core + 31 dev-team + 15 product planning + 7 FinOps regulatory + 6 technical writing + 9 PMO)
- 38 specialized agents - 10 review/planning + 12 developer + 4 product research + 3 FinOps regulatory + 3 technical writing + 6 PMO
- 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 — Brazilian regulatory compliance (finops-team), 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)ring:review-slicer - Review slicer (groups large multi-themed PRs into thematic slices for focused parallel review)ring:write-plan - Implementation planning agentring:codebase-explorer - Deep architecture analysis (deep-analysis, complements built-in Explore)- Use
ring:codereview skill to orchestrate parallel review workflow
