OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/statistical-and-uncertainty-visualization/SKILL.md
Design statistically honest and uncertainty-aware visualizations. Use when the user needs help showing distributions, intervals, confidence, missingness, sampling effects, or analytical rigor in charts and dashboards.
OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/testing-data-visualizations/SKILL.md
Test data visualizations and dashboards. Use when the user needs chart or diagram test strategy, screenshot or image diff testing, visual regression, mocked or synthetic chart data, component or unit tests, E2E dashboard QA, interactive UML-like diagram verification, scroll-driven story verification, export verification, or guidance on avoiding brittle over-testing.
OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/threejs-data-visualization/SKILL.md
Render WebGL-accelerated data visualizations with Three.js, raw WebGL, deck.gl, luma.gl, PixiJS, Sigma.js, Plotly WebGL traces, ECharts GL, CesiumJS, Babylon.js, or related GPU libraries. Use when the visualization needs true spatial structure, dense 2D or 3D GPU rendering, particle or flow animation, volumetric views, or interactive exploration that adds real analytical value.
OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/typescript-data-visualization-engineering/SKILL.md
Build typed data visualizations in TypeScript. Use when the user wants TypeScript visualization code, typed data models, browser visualization components, UML-like diagram models, interactive graph or architecture diagram contracts, scroll-driven scene contracts, library selection guidance, or a maintainable visualization architecture beyond React- or Next-specific concerns.
OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/uml-and-software-architecture-visualization/SKILL.md
Design, critique, read, write, render, and implement UML and UML-like software diagrams. Use when the user mentions UML, sequence diagrams, class diagrams, activity diagrams, state machines, use case diagrams, component diagrams, deployment diagrams, object diagrams, package diagrams, profile diagrams, timing diagrams, communication diagrams, interaction overview diagrams, composite structure diagrams, ERDs, database schema diagrams, C4, BPMN, swimlanes, flowcharts, network diagrams, application architecture diagrams, software architecture diagrams, diagram-as-code, model-as-code, XMI, UMLDI, PlantUML, Mermaid, Graphviz DOT, D2, Structurizr, DBML, diagrams.net/draw.io, Kroki, or interactive diagram editors and explorers.
OpenAISkillopenai/plugins/plugins/build-web-data-visualization/skills/visualization-strategy-and-critique/SKILL.md
Choose, lay out, critique, and explain data visualizations. Use when the user asks what visualization fits a dataset or goal, how a chart, dashboard, operational workspace, UML-like diagram, or software architecture diagram should be composed or interacted with, asks for visual page design, a layout mockup, generated large-screen and mobile concept images, or to be shown what a visualization could look like, when domain-native contextual surfaces or graphical backgrounds may help, when scrollytelling or parallax might be appropriate, wants a critique of an existing visualization, or needs guidance grounded in trusted visualization theory and practice. For advanced visual design or page-layout prompts where composition affects understanding, Codex must generate and show both large-screen and mobile portrait image concepts before implementation or text-only design handoff, plus mobile landscape when needed.
OpenAISkillopenai/plugins/plugins/canva/skills/canva-brand-check/SKILL.md
Check a Canva design against a brand kit and report where it diverges — off-palette colors, non-brand fonts, logo misuse, and off-tone copy. Read-only; makes no changes. Use when the user asks "is this on brand", "check this against our brand kit", "do a brand review", "does this match our brand guidelines", or "brand-check my design".
OpenAISkillopenai/plugins/plugins/canva/skills/canva-branded-presentation/SKILL.md
Create on-brand Canva presentations from an outline or brief. Use when the user asks to create a branded presentation, make an on-brand deck, turn an outline into slides, or generate a presentation from a brief. Input can be text directly in the message, a Canva design ID, a reference to a Canva doc by name, or a Canva design link (e.g., https://www.canva.com/design/...).
OpenAISkillopenai/plugins/plugins/canva/skills/canva-bulk-create/SKILL.md
Bulk-create Canva designs from tabular data using a brand template with autofill fields, producing one design per row. Use when users say "bulk create designs from this CSV", "generate one design per row", "create a design for each product", "batch generate from a template", or "autofill a template from a spreadsheet". Accepts any tabular data source — uploaded files, pasted tables, JSON, or URLs.
OpenAISkillopenai/plugins/plugins/canva/skills/canva-design-feedback/SKILL.md
Read a Canva design and return structured, actionable design feedback — visual hierarchy, copy/messaging, layout & spacing, consistency, readability, and accessibility. Read-only; makes no changes to the design. Use when the user asks to "review my design", "give me feedback on this", "critique my deck/poster/flyer", "how can I improve this design", or "what's wrong with this slide".
OpenAISkillopenai/plugins/plugins/canva/skills/canva-edit-design/SKILL.md
Make edits to an existing Canva design — change or fix text, replace/insert/delete images and videos, reformat text (size, weight, style, color, alignment, lists, line height), reposition or resize elements, and update the title. Use when the user wants to change, edit, update, fix, translate, replace, or reformat content in a specific Canva design. This is the safe edit engine that other Canva skills (e.g. implement-feedback) build on.
OpenAISkillopenai/plugins/plugins/canva/skills/canva-implement-feedback/SKILL.md
Implement reviewer feedback on a Canva design. Reads all comment threads, synthesises what reviewers want, makes the clear-cut changes directly, and flags anything that needs a human decision. Use when the user asks to "implement feedback on my deck", "address comments on a design", "apply review feedback", "fix the comments on my presentation", or "implement the feedback".
OpenAISkillopenai/plugins/plugins/canva/skills/canva-resize-for-social-media/SKILL.md
Resize a Canva design into multiple social media formats (Facebook post, Facebook story, Instagram post, Instagram story, LinkedIn post). Use this skill when users want to resize Canva designs specifically for multiple social media platforms in one operation, rather than resizing to a single format manually.
OpenAISkillopenai/plugins/plugins/canva/skills/canva-translate-design/SKILL.md
Translate all text in a Canva design to another language, creating a translated copy. Faster than manually copying and editing each text box in Canva's editor. Use when users say "translate my design to [language]", "make a Spanish/French/etc version", or "localize my Canva design".
OpenAISkillopenai/plugins/plugins/chatcut/skills/connect-chatcut-desktop/SKILL.md
Install, open, connect, or repair ChatCut Desktop when the chatcut_desktop MCP tools are missing or unavailable. Do not use from a managed agent already running inside ChatCut Desktop, or when chatcut_desktop tools are already available.
OpenAISkillopenai/plugins/plugins/circleci/skills/builds/SKILL.md

OpenAISkillopenai/plugins/plugins/circleci/skills/config/SKILL.md
Optimize CircleCI configuration for speed, reliability, and maintainability. Use when users ask to improve `.circleci/config.yml`, reduce CI runtime, tune caching/workspaces/parallelism, remove pipeline waste, or fix flaky pipeline behavior caused by configuration choices.
OpenAISkillopenai/plugins/plugins/cloudflare/skills/agents-sdk/SKILL.md
Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, or chat applications.

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
