Measuring and optimizing three.js speed: render statistics, memory counters, fewer draw calls via merging, instancing, batching and LOD, fill rate, shadows, CPU work per frame, shader stalls and GPU compute for particles, WebGL or WebGPU with TSL. Use when a scene is slow, janks or exceeds memory.

This skill is required to create, read, edit, review, or comment on Figma specs. You must read it when working on a PRD, brief, RFC or any kind of document in either a standalone Figma spec or a Figma spec embedded in a Figma Design or Figjam file.

Spawn N parallel candidates at the same task, pick a base, graft the strongest parts of the losers into it. Use for /arena, 'arena this', 'throw it in the arena', or when one attempt at a non-trivial artifact would lock in the wrong shape.

CLI harness for Krita digital painting — manage projects, layers, filters, and export via command line. Use when automating Krita workflows, batch processing images, or operating Krita without a GUI.

Use this skill when the user wants to convert an Airflow task that uses TableauOperator or TableauRefreshWorkbookOperator (apache-airflow-providers-tableau) into an equivalent Orchestra pipeline task targeting Tableau Cloud. Triggers: any mention of migrating or rewriting Tableau Airflow tasks to Orchestra; Airflow DAG code containing TableauOperator, TableauRefreshWorkbookOperator, or TableauJobStatusSensor.

Use this skill when the user wants to convert a Prefect @task function containing arbitrary Python logic (computation, API calls, pandas, boto3, etc.) into an equivalent Orchestra Python pipeline task. Triggers: any mention of migrating or rewriting Prefect @task functions to Orchestra; Prefect flow code with @task decorators that are not a dedicated integration (not dbt/Airbyte/Fivetran); ShellOperation tasks running Python scripts.

Run agent-browser + Chrome inside Vercel Sandbox microVMs for browser automation from any Vercel-deployed app. Use when the user needs browser automation in a Vercel app (Next.js, SvelteKit, Nuxt, Remix, Astro, etc.), wants to run headless Chrome without binary size limits, needs persistent browser sessions across commands, or wants ephemeral isolated browser environments. Triggers include "Vercel Sandbox browser", "microVM Chrome", "agent-browser in sandbox", "browser automation on Vercel", or any task requiring Chrome in a Vercel Sandbox.

Simplify the changes of the current PR or working tree with an ablation study - remove each piece of the diff and keep only what is proven needed - so the result has just-right abstraction, minimal clean code, and stays robust and universal. Use when asked to simplify, slim down, clean up, or reduce the current changes or PR.

Diagnoses and repairs repository setup and guarded Git workflows for Claude Code or Codex — environment repair, startup sync, hook auditing, collaborator handoff. Use when a repo won't run, a teammate onboards, hook output duplicates, or commit/push/conflict needs guarding. Not for lost-commit recovery (use git-safety-net), GitHub ops (use github-ops), or history scrubbing (use github-sensitive-data-cleanup).

Use when a dotnet-inspect change needs expensive evidence outside normal PR CI, or when preparing release certification; coordinate Deep Inspect lanes (full slow tests, cross-platform certification, IL round-trip sweep, corpus sensors, package discovery, validity scans, and analysis census).

Use this skill for any question or action about the user's AI/GenAI applications or agents — their behavior, prompts/responses, quality, hallucinations, guardrails, security, cost/tokens, errors, evaluations/policies, model pricing, or configuration — including comparing or tracking agents over time. It covers both analyzing AI telemetry (GenAI spans) and managing AI Center config via the `cx ai-center` commands.

Use only when the user explicitly requests a review or audit of backend code under `api/`. Supports pending-change, file-focused, and pasted-diff reviews. Do not use for implementation-only requests, diagnosis without review intent, frontend code, or backend code outside `api/`.

Write and restructure Phoenix documentation in docs/ using the Diátaxis framework, with ASD-STE100 Simplified Technical English for technical content. Use when adding, editing, or reviewing any docs page.

Audit recent changes to Phoenix's user-facing surfaces (Python clients, TypeScript clients, CLI, REST/GraphQL APIs) and patch the three external-facing agent skills — `phoenix-tracing`, `phoenix-cli`, and `phoenix-evals` — so they stay in sync with what actually shipped. Use this skill whenever a user asks to update those skills, sync the skills with recent changes, audit skill drift, check what client/CLI/API changes need to land in the skills, or mentions "skill freshness", "skill drift", "stale skills", or "are the skills up to date". Also trigger when shipping a notable client/CLI/API change and the user asks "do the skills need updating?". Default window is the last 7 days on `origin/main`; user may override.

Diagnoses why your product team ships slowly and produces a velocity plan with a baseline, a bottleneck map, the top 3 interventions and a stop-doing list. Use it when you say 'we're too slow', 'how do we ship faster', 'projects keep slipping', 'too many meetings', 'approvals take forever', 'our releases are scary', 'velocity', 'cycle time', 'we hired more people and nothing got faster' or 'AI made coding fast but we still ship slowly'. Draws on 226 Lenny's Podcast guests including Farhan Thawar, Nicole Forsgren and Melissa Perri.

Trust Wallet CLI (`twak`) — install, create wallets, check balances, send tokens, swap, view history, set price alerts, DCA automations, limit orders, manage ERC-20 approvals, check token risk, browse trending/DApps, and run x402 micropayments. Use whenever the user wants to use the twak CLI, manage a crypto wallet from the terminal, send or swap tokens via command line, check portfolio, create price alerts, set up DCA, create limit orders, approve ERC-20 spenders, or interact with Trust Wallet from a shell. Also covers MCP server setup for AI agents.

Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).

Take a request all the way to done, hands-off, through the right Compound Engineering skills. A code change ends as an open pull request, pushed without stopping. Use only when the user explicitly asks for autonomous end-to-end work or invokes lfg directly. Use ce-plan, ce-work, ce-debug, or ce-commit-push-pr for work the user reviews step by step.

Generates infographic image card series with 12 visual styles, 8 layouts, and 3 color palettes. Breaks content into 1-10 cartoon-style image cards optimized for social media engagement. Use when user mentions "小红书图片", "小红书种草", "小绿书", "微信图文", "微信贴图", "image cards", "图片卡片", baoyu-xhs-images, or wants social media infographic series.

Downloads YouTube video transcripts/subtitles and cover images by URL or video ID. Supports multiple languages, translation, chapters, and speaker identification. Caches raw data for fast re-formatting. Use when user asks to "get YouTube transcript", "download subtitles", "get captions", "YouTube字幕", "YouTube封面", "视频封面", "video thumbnail", "video cover image", or provides a YouTube URL and wants the transcript/subtitle text or cover image extracted.
