Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
Scan the session for compound-worthy learnings, then commit the working tree with a repo-appropriate, value-communicating message.
Garbage-collect the knowledge stores — audit docs/solutions/ and AGENTS.md against the current code.
Capture this session's durable learnings and route each to the right knowledge store, every write user-gated. Use at loop end when /commit's opening scan finds candidates, when /diagnosing-bugs closes out a fix, or when the user wants to capture, remember, or write down a learning, convention, gotcha, or preference.
Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.
Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to be grilled about a plan, wants a decision stress-tested, or when requirements are fuzzy before a spec is written.
Compact the conversation into a handoff document a fresh session can resume from.
Implement a spec or a single ticket, driving TDD at the seams agreed in the spec.
