Unity 6 performance profiling and optimization guide. Use when profiling, optimizing frame rate, reducing memory usage, debugging performance bottlenecks, or using the Profiler, Memory Profiler, or Frame Debugger. Based on Unity 6.3 LTS documentation.
Prove whether a given directory, file, exported symbol, function, component, constant, hook, type, or helper has "no real consumers", then decide whether to delete it. Use for dead code cleanup, unused code detection, unused export audits, deletion safety checks, and consumer searches; it only answers questions of consumption relationships and deletion safety, not whether something that is still used is actually necessary - for that, use necessary-code-audit.
Build and deploy web apps to the cloud. Supports React, Vue, Astro, Next.js (static), vanilla HTML/CSS/JS, and serverless functions. Sites deploy to *.rebyte.pro with automatic SSL. Use when user asks to "deploy", "publish", "host", or make their app "live". Triggers include "deploy my app", "make it live", "publish site", "host my app", "deploy website", "put it online".
Generate API documentation by scanning Controller classes, extracting endpoint URLs, HTTP methods, parameters, and response structures, then producing standardized docs from templates. Use when the user explicitly mentions generating API documentation, creating API docs, scanning interfaces, or documenting REST APIs. Do not trigger for generic documentation requests without explicit API mention.
Comprehensive skill for building, migrating, and maintaining Astro v7 projects. Covers best practices from the official AGENTS.md, the v6→v7 migration path, validation of breaking/deprecated patterns, AI-enhanced dev server usage (background mode, JSON logging), advanced routing with src/fetch.ts, route caching, Sätteri Markdown, and the Rust compiler. Use when the user mentions 'Astro', '.astro files', 'astro dev', 'astro build', 'islands architecture', 'content collections', 'SSG', 'SSR adapter', 'upgrade to Astro 7', 'migrate Astro', 'Astro v7', 'Astro v6', 'Sätteri', 'route caching', 'Astro.cache', 'astro dev --background', 'src/fetch.ts', 'advanced routing', 'Hono + Astro', 'Rolldown', 'Vite 8', 'queued rendering', 'CDN cache provider', 'Astro AI', 'related content', 'related posts', 'vector embeddings Astro', 'astro-related-content', or asks about static site generation with Astro.
Use when adding GPU particles via `bevy_hanabi 0.20.0` (`HanabiPlugin`, `EffectAsset`, `ParticleEffect`, `ExprWriter`, `SpawnerSettings`, modifiers like `SetPositionSphereModifier` / `ColorOverLifetimeModifier`), rendering Gaussian splats via `bevy_spark`, picking between hanabi and `bevy_spritesheet_animation` flipbooks or `bevy_vector_shapes`, writing custom `Material` + `.wesl` shaders for fire/water/distortion, or budgeting GPU costs and WebGPU compatibility in Bevy 0.20.
Generate complete JSON-LD schema markup for blog posts including BlogPosting, Person, Organization, BreadcrumbList, FAQPage, and ImageObject. Validates against Google requirements and warns about deprecated types. Use when user says "schema", "blog schema", "json-ld", "structured data", "schema markup", "generate schema".
This skill should be used when the user asks about Bootstrap grid system, Bootstrap containers, Bootstrap breakpoints, Bootstrap columns, Bootstrap rows, Bootstrap gutters, Bootstrap responsive layout, Bootstrap CSS Grid, Bootstrap z-index, Bootstrap row-cols, Bootstrap offset classes, Bootstrap column ordering, how to create responsive layouts with Bootstrap, how to use Bootstrap grid, Bootstrap column sizing, Bootstrap auto-layout columns, or needs help with Bootstrap page layout and responsiveness.
Build browser or server token bridging across chains with Circle App Kit or standalone Bridge Kit. Bridges USDC across CCTP chains (EVM and Solana) and CCTPx tokens on supported EVM routes, including registry aliases such as wETH, cirBTC, and EURC plus registry-listed token IDs, through the same `kit.bridge()` call. Supports browser wallets, private-key and Circle Wallets adapters, bridge events, transfer speed (FAST/SLOW), Forwarding Service, and recovery. Bridge operations require no kit key. Use when: bridge a token across chains, bridge USDC, bridge a CCTPx token alias or token ID, move tokens between chains, build wallet-connected bridge UIs, configure Viem/Ethers/Solana adapters, or use @circle-fin/bridge-kit, @circle-fin/app-kit, CCTP, CCTPx, forwarding, or bridge routes
AI-powered generation of complete trading strategy code. Uses create_strategy and create_prediction_market_strategy to transform requirements into production-ready Python code. Most expensive AI tool ($1.00-$4.50 per generation). Generates complete Jesse framework strategies with entry/exit logic, position sizing, and risk management. Use after exploring data and optionally generating ideas. ALWAYS test with test-trading-strategies before deploying.
Builds and manages open source Python library communities including CONTRIBUTING.md, CODE_OF_CONDUCT.md, issue/PR templates, contributor recognition, and GitHub automation. Use when setting up community infrastructure, improving contributor experience, or managing project governance.
Manage dotfiles and secrets with chezmoi. Use for initializing chezmoi, adding/editing configuration files, creating templates for multi-machine setups, encrypting sensitive files, integrating password managers (1Password, Bitwarden, pass, etc.), running scripts during apply, and syncing dotfiles across machines. Triggers on dotfile management, chezmoi commands, configuration templating, or secrets in config files.
Scan C/C++ codebases for code quality issues including extra large files/functions and circular dependencies. Use when the user asks to check file sizes, find oversized functions, detect circular dependencies, analyze code complexity, find code smells, or identify maintainability issues in C/C++ code. Supports scanning individual files or entire directories with configurable thresholds.
Handles Tambo component streaming, loading states, and persistent state. Use when implementing streaming UI feedback, tracking prop streaming status, managing partial props, or persisting component state across sessions with useTamboStreamStatus or useTamboComponentState.
Load this skill whenever building, editing, or deploying a Goldsky Compose app — it is the reference layer that gives the concrete rules for how to build one: the exact shape of compose.yaml (every top-level, task, and trigger field), every `goldsky compose` CLI flag, the TaskContext API (env, fetch, callTask, logEvent, evm, collection), wallet APIs (smart wallet, BYO EOA), gas sponsorship, contract codegen, the dashboard URL, and pricing. Consult it before writing or editing any compose.yaml or task file — do not synthesize the manifest/CLI/API shape from memory — and also to answer any user question about how Compose works or what a field, flag, or API does. Pairs with /compose (the entry-point build guide, loaded first); use /compose-doctor to debug a broken app. Do NOT load for Turbo, Mirror, Subgraphs, Edge, or Boost — those have their own reference skills.
Reverse-engineer a website's internal API by recording browser traffic into a HAR file, then generate a standalone client or CLI that calls the endpoints directly, with no browser needed after the first recording. Use when asked to "derive a client", "build a CLI for <site>", "reverse engineer this site's API", "record network requests", "turn this site into an API", or when the same site will be automated repeatedly and direct HTTP calls would beat driving the browser every time.
Build Solana trading applications combining DFlow trading APIs with Helius infrastructure. Covers spot swaps (imperative and declarative), prediction markets, real-time market streaming, Proof KYC, the DFlow Agent CLI for autonomous trading, transaction submission via Sender, fee optimization, shred-level streaming via LaserStream, and wallet intelligence.
Convert a specific existing Lightning web component (LWC) into a declarative HXL / Agentforce widget, end to end. Gates on experience-lwc-widget-assess and stops when a widget cannot serve the LWC's purpose; otherwise hands the derived field shape to platform-widget-generate and wires the widget as the Lightning Type renderer. TRIGGER when: the user wants to convert, migrate, port, rebuild, or turn a named LWC into a widget or declarative Agentforce widget, or asks for a widget built from an existing LWC component. DO NOT TRIGGER when: the user only wants to know whether an LWC can become a widget (use experience-lwc-widget-assess), or wants a widget for a data shape, entity, or Lightning Type with no existing LWC (use platform-widget-generate or platform-lightning-type-widget-coordinate).
Scan the codebase and classify every fact by lifecycle stage — tag @draft, @spec, or @implemented based on what the code actually shows. Add missing facts, fix inaccurate ones, remove obsolete ones. Use when asked to discover facts, bootstrap or update a fact sheet, scan the codebase for truths, sync facts to match the code, or audit the fact sheet for accuracy.
Deploy HTML/CSS websites to ERPNext/Frappe (v15/v16) as Web Pages via the REST API. Use this skill whenever a user wants to host a website on ERPNext, deploy HTML mockups to Frappe, create Web Pages programmatically, configure Website Settings, or integrate Frappe's Discussion system as a forum. Also use when the user mentions "website on ERPNext", "Web Page API", "Page Builder", "Web Template", or wants to serve custom HTML from Frappe. Covers: Web Pages with Page Builder, custom Web Templates, Website Settings (navbar, footer), CSS management, Frappe Discussion integration, and deployment scripting.
Portable Git workflow skill for AI coding agents that turns messy AI-generated changes into clean Git history. Use for smart Conventional Commits, logical commit splitting, branches, checks, pull and push, GitHub PRs and issues, secret scanning, commit planning, Git status and history, repository diagnosis, and merge or rebase conflict resolution with Claude Code, OpenAI Codex, Cursor, and other Agent Skills-compatible tools.
