Development
Use when an AI agent needs to operate the local Calicat CLI to extract design data, interaction data, PRD data, canvas/page structure, or screenshots from Calicat links or file ids. Trigger especially when the user provides a Calicat design URL, asks the agent to parse file_id, canvas id, or layer id correctly, or asks for whole-canvas frontend implementation that must fetch page data progressively instead of loading all design JSON at once. Also use when the agent needs to verify whether the local Calicat CLI is installed, check its version, or decide whether CLI update/install guidance is needed before continuing.
Create SEO-optimized pages at scale using programmatic/template-based approaches. Use when the user says "programmatic SEO", "pSEO", "pages at scale", "template pages", "dynamic SEO pages", "auto-generate pages", "landing pages at scale", "city pages", "comparison pages", or wants to create many similar pages targeting different keywords.
Use when writing or debugging code that imports vue-i18n (Vue 3 internationalization). Covers createI18n, useI18n, message syntax, i18n-t/i18n-n/i18n-d components, pluralization, datetime and number formatting, TypeScript schemas, lazy loading, bundle optimization, and v10/v11/v12 migration.
Retrieves up-to-date documentation, API references, and code examples for any developer technology. Use this skill whenever the user asks about a specific library, framework, SDK, CLI tool, or cloud service — even for well-known ones like React, Next.js, Prisma, Express, Tailwind, Django, or Spring Boot. Your training data may not reflect recent API changes or version updates. Always use for: API syntax questions, configuration options, version migration issues, "how do I" questions mentioning a library name, debugging that involves library-specific behavior, setup instructions, and CLI tool usage. Use even when you think you know the answer — do not rely on training data for API details, signatures, or configuration options as they are frequently outdated. Always verify against current docs. Prefer this over web search for library documentation and API details.
Use the Dosu CLI to authenticate and configure coding agents; manage Libraries, Agents, sources, Monitor, documents, reviews, threads, topics, members, integrations, and deployments; query knowledge; or audit a repository for Dosu-generated docs. Use for Dosu platform work that should be done from a terminal instead of the web app.
Elite website image-to-code skill for Codex. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards, generate fresh standalone images for sections or detail views instead of cropping old ones, avoid lazy under-generation, avoid cards-inside-cards-inside-cards UI, and keep the hero clean, spacious, readable, and visible on a small laptop.
Core rendering pipeline for three.js using WebGLRenderer and WebGPURenderer, canvas sizing, device pixel ratio, color space and tone mapping, output encoding, WebGL/WebGPU render targets, Info statistics, and addon overlay renderers (CSS2D/CSS3D/SVG). Use when tuning the draw loop, performance, or switching WebGPU vs WebGL; for EffectComposer passes use threejs-postprocessing; for XR session lifecycle use threejs-webxr; for shader graphs use threejs-node-tsl.
Use when a GitHub issue needs triage — typically one carrying status/needs-triage label, a freshly opened issue without type/priority labels, or when the user says "triage #N" / "triage this issue". One issue per invocation; for backlog walkthroughs, the caller loops.
Expert guidance for designing Azure solutions using Azure Architecture. Covers reference architectures, solution ideas, design patterns, technology choices, architecture styles, best practices, anti-patterns, example workloads, and migration guides. Use when designing AKS or App Service apps, SAP/ERP or IoT workloads, hybrid/Arc setups, or AI/ML solutions on Azure, and other Azure Architecture related development tasks
Checks requirements.txt, pyproject.toml, and package.json dependency manifests for surface-level direct-dependency footguns: standard-library shadowing pins, abandoned backports, unpinned dependencies, and obvious intra-manifest conflicts, plus opt-in PyPI yanked releases. Use when the user asks to check a manifest for dependency problems, asks why dependencies won't install or whether anything is wrong with their dependencies, wants a dependency autopsy, or suspects dependency manifest rot. Runs offline by default as a local tool for the user's own project, not repository CI
Operate Orca-managed worktrees, folder contexts, terminals, repos, automations, artifacts, skill sharing, worktree comments, and Orca's embedded browser through the `orca` CLI. Use when the user says "$orca-cli", "Orca worktree", "child worktree", "spawn codex/claude in a worktree", "read/wait/send Orca terminal", "handoff" / "handover" / "give this to another agent", "Orca browser", "orca artifacts", or "share skills". Prefer it over raw git worktree, ad hoc PTYs, or Computer Use when Orca state is involved. Use Computer Use only when a visible window needs GUI control that a CLI, filesystem, or API cannot do.
Core ML, Create ML, Vision framework, Natural Language framework, on-device ML integration. Use when user wants image classification, text analysis, object detection, sound classification, model optimization, or custom model integration. Covers Core ML vs Foundation Models decision.
Audit and clean the Remotion GitHub masterplan hierarchy. Use when finding open issues that lack a masterplan ancestor, identifying orphaned issues that need a parent, or recursively removing closed issues from the masterplan rooted at issue #9081.
One-time project initializer for Inertia Rails skills. Detects the stack and frontend framework (React/Vue/Svelte) from Gemfile and package.json, offers to install recommended dependencies (alba-inertia, js-routes, pagy, shadcn), and generates a CLAUDE.md section configuring which skill patterns apply. Use when first installing these skills, bootstrapping a new Inertia Rails project, or when the stack changes.
A working type director’s reference for selecting, pairing, and shipping typefaces with real taste. Covers a broad, opinionated catalog of typefaces and foundries (libre through commercial), a mood/era/register-driven selection framework that never collapses to one answer, font pairing as logic, fluid type scales, variable-font axes (incl. opsz/GRAD), OpenType features, web-font performance (subsetting, font-display, size-adjust fallback metrics), and licensing literacy (SIL OFL vs commercial EULA, desktop/web/app, trials). Explicitly retires the overused AI-design defaults (Inter, Roboto, Montserrat, Poppins, Fraunces, Geist, Söhne, the Fontshare/ITF starter pack) and names fresher alternatives in every role. Use for font selection, pairing, type scales, web-font optimization, variable fonts, OpenType, and typographic systems. NOT for logo/wordmark design, icon fonts, general CSS, or image-based/raster typography.
Appwrite Rust SDK skill. Use when building server-side Rust applications with Appwrite. Covers async client setup with API keys, user management, TablesDB database/table/row operations, file storage, function executions, permissions, queries, and error handling. Uses the crates.io `appwrite` package and Tokio.
