By hoblin
Implements a structured RPI (Research, Planning, Implementation) workflow with context engineering for AI-assisted development. Enables session handoffs, persistent thought notes, implementation plan creation/validation, and multi-agent PR reviews with Rails/Ruby-specific code analysis.
Iterate on existing implementation plans with thorough research and updates
Implement technical plans from ./thoughts/shared/plans with verification
Create git commits with user approval and no Claude attribution
Create handoff document for transferring work to another session
Capture findings or context as a persistent note in the thoughts system
Analyzes codebase implementation details. Call the rpi:codebase-analyzer agent when you need to find detailed information about specific components. As always, the more detailed your request prompt, the better! :)
rpi:codebase-pattern-finder is a useful subagent_type for finding similar implementations, usage examples, or existing patterns that can be modeled after. It will give you concrete code examples based on what you're looking for!
Need to learn how to use a library, gem, or framework? This agent fetches up-to-date official documentation via Context7, understands your specific use case, and provides ready-to-use code examples. Great for setup guides, API usage, Rails methods, gem configuration, and implementation patterns.
Documentation reviewer for PR audits. Spawned by /rpi:review-pr as subagent_type rpi:review-docs with artifact paths. Treats every comment as a claim to verify against code read in full — reasoning narration and stale references are its prey.
Generic code reviewer for PR audits in domains without a dedicated expert. Spawned by /rpi:review-pr as subagent_type rpi:review-generic with artifact paths plus the domain and focus list. Better a generic reviewer than an unreviewed domain.
