REQUIRED when modifying any file in packages/playground-ui or packages/playground. Triggers on: React component creation/modification/refactoring, UI changes, new playground features, bug fixes affecting studio UI. Generates Playwright E2E tests that validate PRODUCT BEHAVIOR, not just UI states.
Re-review a pull request after a push — reconcile the previous review against the new commits, look for new defects the push introduced, then a fresh pass over the whole PR, and finish with a verdict on the PR.
Scaffold a new Harbor benchmark adapter by running harbor adapter init and then guide implementation using the Adapters Agent Guide as the authoritative spec.
Write Harbor task verifiers using Reward Kit. Use when creating or editing a task's tests/ directory, adding grading criteria, setting up LLM/agent judges, or designing verifiers that produce a reward score.
Create or reuse Hugging Face dataset PRs for harborframework/parity-experiments and upload Harbor parity/oracle result folders efficiently with sparse checkout, raw git pushes, and Git LFS.
Generate an Excalidraw whiteboard in Sean's hand-drawn video style (Excalifont, roughness 1, green signature, socials + watermark, source labels). Use whenever the user wants a whiteboard, diagram, teaching board, or "chart" for a video or the docs/whiteboards gallery — anything Sean will film with.
Walk Sean through an incoming waku-agent PR or issue and present it his way — four fixed sections: what this is, why it matters, how HE can test it with you as copilot, and are we ready to merge / reply / close and why. Use whenever Sean asks to look at, test, triage, or decide on a pull request or an issue, and…
Commit and push the current work properly — lint, run the release gate, write a detailed commit message, push to GitHub. Use whenever work reaches a milestone or the user says ship it, commit, or push.
Paint a complete visual universe with genjutsu - art direction brainstorm, design system, implementation, audit. Anti-AI-slop design pipeline. Adapts to Web, Android (Compose), Apple (SwiftUI).
Use when creating, improving, finding, or auditing agent skills - the user says 'create a skill', 'do I have a skill for X', 'improve the X skill', 'which skill should I use', asks whether a skill exists for a task, or wants to validate, test, evaluate, package, or health-check skills. Also use for skill ecosystem…
Use when validating the SkillForge validator itself - exercises every supported frontmatter feature: boolean user-invocable, an allowed-tools block list, and nested metadata with an inline list.
Review Benchflow or SkillsBench task-run trajectories and integration-test Benchflow code changes. Use this skill whenever the user asks to audit traj health, failed or timed-out runs, healthy pass/fail/timeout status, no-skill leakage, skill loading, reward hacking, verifier isolation, metadata completeness, token…
Find a local Claude Code or Codex session, open the BenchFlow trajectory viewer, and submit it after the user reviews it. Use this skill whenever someone pastes a BenchFlow eval prize line, wants to submit / share / contribute / upload a trajectory, set up traj upload, view a session, or pick a session to send. Also…

Create, audit, and repair short page-native diary comics around an existing authorized recurring character, with story-directed page rhythm, exact dialogue, directional-surface proof, and original-resolution visual QA. Use when extending an established recurring-character series from an anecdote, conversation, dream…
Control Herdr, a terminal multiplexer for coding agents. Use only when the user explicitly mentions Herdr or asks to use Herdr to inspect or control panes, tabs, workspaces, commands, or another agent. Do not use merely because a task could benefit from a background terminal, delegation, or parallel work. Requires…
Inspect, select, author, modify, or review NiceEval E2E and Unit test owners. Use when a change needs a test strategy, an existing test must be traced to its Feature or Use Case, or a bug requires public-entry E2E TDD.
Query .NET APIs across NuGet packages, platform libraries, and local files. Search for types, list API surfaces, compare and diff versions, find extension methods and implementors. Use whenever you need to answer questions about .NET library contents.
