Tdd
Test-driven development with red-green-refactor discipline and vertical-slice tracer bullets. Use this skill whenever the user is building or fixing code in testable layers — parsers, formatters, services, pure functions, data models, CLI commands — even if they don't explicitly say "TDD". Triggers include "add a feature to the parser", "fix a bug in the formatter", "implement this utility", "wri…
Verify Before Done
Prevent false "it works" claims. Before declaring anything done, fixed, or passing, run the verification that actually proves it. Three-level evidence rubric (Mechanical / Behavioral / Consensus) with red flag detection for phrases like "should work", "looks good", "probably passing". Use this skill whenever you or the user is about to claim something is complete, fixed, working, or passing — eve…
Cookoff
Auto-grill a plan, spec, or ticket by running Claude and Codex as interrogator/answerer pairs instead of interviewing the user. Two modes — relay (iterative back-and-forth between Claude and Codex) and parallel (two swapped streams merged into one spec). Produces a pre-chewed artifact where the user only reviews the result, not sits through the interview. Use this skill whenever the user says "co…
Grill With Docs
A grilling session that stress-tests a plan against the project's documented domain model — sharpens fuzzy terminology, challenges it against the existing glossary, cross-references it with the code, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallize. The domain-aware variant of grill-me — use this instead when the repo has (or should have) a CONTEXT.md glossary or docs/…
Release Plugin
Ship a Claude Code plugin update — detect the plugin, determine the version bump, update plugin.json and CHANGELOG, stage surgically, commit, push, and (for multi-branch repos) merge to the default branch via a worktree. Prints the /plugin update and /reload-plugins commands for the user to run in Claude Code. Use this skill whenever the user has finished editing a plugin's skills and wants to pu…
Grill Me
Interview the user relentlessly about a plan, spec, or ticket until every branch of the decision tree is resolved. Produces a per-dimension ambiguity report (Goals / Acceptance / Boundaries / Alternatives / Assumptions) and an aggregate gate. Use this skill whenever the user is drafting a spec, proposing a design, debating an approach, or describing work to hand off — even if they don't say "gril…
Tech Spec
Turn a PRD into a technical implementation spec. Bridges the "what and why" of a PRD and the "how" an agent needs to execute. Module decomposition with deep-module emphasis, sequencing by tracer-bullet principles, and a grill gate before exit. Use when the user says "tech-spec", "write a technical spec", "turn this PRD into a plan", or after /write-prd when the next question is "how do we actuall…
Handoff
Compact the current conversation into a handoff document so a fresh agent can pick up the work without re-deriving context. Writes a self-contained brief to the OS temp directory — what's been done, what's left, key decisions, gotchas, and which skills to invoke next. Use when the user says "handoff", "write a handoff", "hand this off", "compact this for a new session", "summarize this for anothe…
Design Interface
Explore multiple radically different interface designs for a feature in parallel before committing to one. Uses parallel sub-agents to generate distinct approaches so you can compare tradeoffs rather than anchoring on the first idea. For UI/UX interface work specifically — not API interface design. Use when the user says "design-interface", "let's explore some designs for X", "what are the option…
Improve Codebase
Architectural review and improvement proposals. Reads the codebase for structural opportunities — shallow modules that should be deepened, leaky abstractions, misplaced complexity — and proposes specific changes with tradeoffs. Uses a four-persona pass (Contrarian, Simplifier, Architect, Hacker) to stress-test proposals before presenting. Not a refactoring bot; it produces proposals, not commits.…
Write Prd
Turn a vague idea into a grounded PRD through user interview, codebase exploration, and Socratic drafting. Passes through the grill-me ambiguity gate before exit. Use when the user wants to write a PRD, spec out a feature, turn a meeting transcript into a plan, or says "write-prd", "write a PRD", "spec this out", "let's PRD this", "turn this into a spec". Also invoked by workflow orchestrators li…
