Review codebase architecture for deepening opportunities — modules where the interface is nearly as complex as the implementation. Uses depth-as-leverage model and the deletion test. Use when the codebase feels tangled, after a burst of fast development, or when asked to review architecture.
Ultra-compressed communication. Drops filler, hedging, and pleasantries while keeping technical terms exact. ~75% token reduction. Use when user says "caveman", "caveman mode", "be terse", or "stop being chatty".
Structured debugging as a state machine: reproduce, minimize, hypothesize, instrument, fix, regression-test. Use when something is broken, a bug needs fixing, tests are failing unexpectedly, or behavior doesn't match expectations.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
Test-driven development with vertical slices. Enforces behavior-focused tests through public interfaces, one red-green-refactor cycle at a time. Use when writing tests, adding test coverage, or building features test-first.
Convert markdown to portable, shareable HTML documents with syntax highlighting and optional tabbed navigation. Use when users say "publish", "make HTML", "make this shareable", "create a document for the team", or want to share output with non-technical audiences.
Generates publication-quality illustrations using a 5-agent pipeline inspired by PaperBanana (academic illustration framework). Orchestrates specialized agents: Retriever, Planner, Stylist, Visualizer, and Critic. Use when users need high-quality, iterative image generation with style consistency and quality review.
Pedagogical code walkthrough that teaches developers about their own code. Explains choices, tradeoffs, alternatives, and refactoring opportunities. Use when users say "teach me", "explain my changes", "walk me through", "what did I build", or want to understand their code at a deeper level. Works on uncommitted changes, last commit, unpushed commits, or a PR.
