YC Office Hours — product validation for a new product, feature, or side-project concept. Startup mode tests demand; Builder mode develops an unvalidated product idea. Use when the user asks whether something is worth building or has an idea whose problem/value is not yet validated. Proactively suggest when the user…
Skill Claude Code
Coordinates staged or parallel jobs across live-verified coding-agent runtimes (Claude Code, Codex, Cursor, and other installed CLIs) and in-session toolkit subagents. Routes each job by capability and risk tier, isolates parallel writers in git worktrees, captures redacted output, resumes interrupted runs, and blocks…
Skill Claude Code
Pack an EXTERNAL repository into a single AI-friendly file (markdown/xml/json). Use for third-party library analysis, security audits, or handoff to external LLMs. Do NOT use to pack the current project for inbound context — the host runtime already reads files lazily. Triggers: 'pack this repo', 'snapshot of X'…
Skill Claude Code
Multi-agent collaboration session. Brings 2-4 agent perspectives into one discussion for architecture decisions and trade-off analysis. Use when asked "should we X or Y?", "let's discuss", or "design review".
Skill Claude Code
CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Four modes: SCOPE EXPANSION (dream big), SELECTIVE EXPANSION (hold scope + cherry-pick expansions), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials). Use when…
Skill Claude Code
Creates structured multi-file implementation plans before build. Scope-aware: trivial tasks exit early, simple tasks get fast plans, complex tasks get full research + phase files + validation. Enforces Gate 1. Activated by /mk:plan or /mk:cook. NOT for ticket complexity analysis against an existing codebase (see…
Skill Claude Code
Analyzes ticket complexity and maps dependencies against an existing codebase before sprint planning. Triggers on 'how complex is this ticket', 'what should we work on first', 'can we fit this in the sprint', 'tech review before planning', 'plan the sprint'. NOT for writing implementation plans (see mk:plan-creator)…
Agent Claude Code needs its repo
Analyzes multiple Jira tickets for sprint planning: dependency mapping, grouping, sequencing, capacity analysis. Internal agent of mk:planning-engine.
Agent Claude Code
Analyzes a single Jira ticket against codebase context for implementation feasibility. Internal agent of mk:planning-engine.
Skill Claude Code
Session-persistent browser automation via Playwright CLI — form filling, screenshots, data extraction, multi-step flows. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information across multiple requests. NOT for AI-driven…
Skill Claude Code
Use when generating visual artifacts — explanations, diagrams, slides, or diff visualizations. Triggers on "explain X visually", "diagram this", "show as slides", "diff against main". NOT for rendering a plan as HTML (see mk:visual-plan), live media generation (see mk:multimodal), browser QA (see mk:qa), or plan…
Skill Claude Code
Use when stuck on approach (not debugging). Strategic unsticking via 7 non-default techniques: simplification cascades, collision-zone thinking, meta-pattern recognition, inversion, scale game, first principles, via negativa. Triggers on complexity spiraling, innovation block, recurring patterns across domains…
Skill Claude Code
Generate or update docs/project-context.md — the single source of truth for project conventions, tech stack, and anti-patterns. Loaded by all agents as a "constitution" to ensure consistent behavior.
Skill Claude Code
Use when creating files and need the correct path, organizing project layout, or enforcing naming conventions. Two modes: advisory (return path) and organize (restructure).
Skill Claude Code
Use when refining a draft user prompt before sending it to a coding agent. Decomposes goal/context/constraints/acceptance/output-format, detects ambiguity and model-coupled framing, then emits a model-agnostic rewrite. Supports --analyze, --score, and --deep. NOT for prompts from scratch (mk:brainstorming)…
Skill Claude Code
Spec-driven manual QA testing and Playwright E2E code generation. Orchestrates browser skills to navigate apps like a human tester, producing structured test reports or production-ready .spec.ts files. Always prompts user for credentials — never guesses or stores auth. Use for QA testing, E2E generation, login flow…
Skill Claude Code
Systematically QA test a web application and fix bugs found. Runs QA testing, then iteratively fixes bugs in source code, committing each fix atomically and re-verifying. Use when asked to "qa", "QA", "test this site", "find bugs", "test and fix", or "fix what's broken". Proactively suggest when the user says a…
Skill Claude Code
Use when writing, reviewing, or optimizing React/Next.js code. Triggers on .tsx/.jsx files, React component work, Next.js routes, bundle optimization, re-render issues, or performance improvements. Auto-activates alongside mk:typescript when React project detected.
Skill Claude Code
Use when a decision needs deep multi-source technical research with cited evidence — technology evaluation, ecosystem comparison, standards/spec fact-finding, "how do others solve X". Triggers on "research X", "deep dive on X", "evaluate X vs Y", "find best practices for X". NOT for library/API doc lookup (see…
Skill Claude Code
Resolve an in-progress git merge or rebase conflict end to end: read the conflict state, recover each side's original intent, resolve every hunk, run the project's checks, and prepare the merge/rebase for an explicitly approved finish. Use when asked to "resolve merge conflicts", "fix this rebase", "finish the merge"…
Skill Claude Code
Triage reviewer comments on a GitHub PR with receiving-code-review discipline — verify each against the codebase, then accept/push-back/clarify, and optionally reply in-thread. Use when responding to received PR feedback. NOT for giving a review (see mk:review-pr); NOT for implementing the fixes (hand off to mk:fix).
Skill Claude Code
Weekly-cadence engineering retrospective. Analyzes commit history, work patterns, and code quality metrics with persistent history and trend tracking. Team-aware: breaks down per-person contributions with praise and growth areas. Use when asked to "weekly retro", "what did we ship", or "engineering retrospective".…
Skill Claude Code
Reviews a GitHub PR with a single shallow correctness/security/breaking/AI-slop checklist and emits a verdict; optionally posts it via gh pr review. Use to review an external or teammate PR. NOT for deep pre-landing audit of your own diff (see mk:review); NOT for responding to received review comments (see…
Skill Claude Code
Multi-pass structural code review with adversarial analysis, scope-aware dispatch, adversarial persona passes, and forced-finding protocol.
