Step-by-step guide for creating your own Claude Skills, from deciding whether a skill is the right tool to writing the SKILL.md file, structuring reference material, and making it trigger reliably. Use when you want to package a workflow, framework, or repeated task into a reusable Skill, when an existing skill is not triggering or not loading the right context, when you are auditing a skill that is underperforming, or when you want to publish a skill for others. Also triggers when someone asks "how do I make a skill" or "what makes a good skill". Useful for individuals, teams, and anyone publishing skills publicly.
A three-card social-media carousel laid out as 1080×1080 squares — three cinematic, on-brand panels with display headlines that connect across the series ("onwards." → "to the next one." → "looking ahead."). Each card has a brand mark, a number / total, a caption, and a "loop" affordance. Use when the brief asks for a "carousel post", "social carousel", "Instagram carousel", "LinkedIn series", "X thread cards", or "三连发".
Software design philosophy guide based on John Ousterhout's "A Philosophy of Software Design." Use this skill during code reviews, architecture discussions, API design, module decomposition decisions, refactoring guidance, complexity analysis, naming and commenting improvements, and error handling strategy design. Trigger when the user mentions "code is too complex", "how to split modules", "interface design", "reduce coupling", "deep/shallow modules", "information leakage", "error handling", "code readability", "design philosophy", "pull complexity down", "define errors out of existence", or similar topics.

Organic story anatomy from John Truby's The Anatomy of Story (有机结构/设计原则/22步骤/道德议题/四角对立/幽灵/场景编排) — the designing principle (story process plus original execution), the seven key steps as the organic spine, all twenty-two steps with the middle-act machinery the beat sheets lack (ghost, fake-ally opponent, plan, opponent's drive, ally's attack, fake defeat, three revelation-and-decision pairs, audience revelation, visit to death, moral decision), four-corner opposition, the moral-argument chain with the hero-opponent power-balance rule, scene weave with structure-step tags and storyline numbers, and the accordion rule (never fewer than seven steps). Kept side by side with the Field/Snyder page maps. Use when the middle act sags into unconnected episodes, when the premise works but the story feels mechanical, when one antagonist cannot carry the theme, when the theme stays stated instead of acted, or when a BS2 board needs an organic second pass.
Implements the Syncfusion Blazor Chart Wizard for guided chart creation. Use this when building interactive chart builders that require step-by-step configuration, data binding, and export features. Covers chart customization, theming, and accessibility.
Write and debug Tampermonkey userscripts—scripts that change or automate a website from inside the browser. Use when the user wants a userscript (Tampermonkey, Greasemonkey or Violentmonkey), wants JavaScript or CSS injected into a site they visit, wants page elements hidden or rearranged, wants a form auto-filled or page data scraped, needs to react to URL changes in a single-page app, needs cross-origin requests from a page script, has a userscript that does not run, or is setting one up in TypeScript. Do NOT use for Selenium, Puppeteer or Playwright automation—use a browser-automation tool; for building a browser extension (WebExtensions/Manifest V3), write it as an extension; or for server-side scripts.
ElevenLabs voice agent creation for client discovery and feedback calls. Use this skill when creating AI voice agents, setting up discovery call agents, or configuring automated phone conversations. Triggers on voice agent creation, ElevenLabs agent setup, or automated call agent requests.

Set up an LLM-judge evaluation that extracts canonical use cases for a PostHog feature at scale and streams the results to a Slack channel as a live feed. Use when someone wants to understand how users are actually using a specific AI/LLM-powered feature in production — what they're investigating, what questions they're trying to answer, and what patterns surface — without manually reading hundreds of traces. Assumes the feature emits `$ai_generation` and `$ai_evaluation` events with `$session_id` linkage to the trigger user's recording (the standard setup post the session-summary linkage PRs).
Pick up bugs a human flagged by pointing at them in the running app, each arriving with the element, the note they typed, and the source file and line. Use when the user says they marked or flagged something, when starting a session on an app someone has been clicking through, when a designer or PM has left feedback in the UI, or when the user describes a problem as “that button there” without saying which file.
Draws fun, sharp isometric stickers (flat fill, thick black outline, extruded slab side) and animates them on a library of After Effects grade keyframe presets, replayed exactly the way lottie-web plays them, so the motion is fluid character animation and never a made up wobble. Any palette (six named sets with Riso by default, two brand colours, one colour, hue shift, custom slots) and four facing directions. Produces icon modules that play live on canvas in any web app (a React component ships with the kit) and export to looping alpha video (webm, HEVC mp4) with a poster. Use for "/fun-isometric", "animated sticker icons", "fun isometric icons", "Lottie style icons", "onboarding illustrations that move", or any request for playful animated icons, empty state art or feature stickers.
Covers Stimulus controller fundamentals: lifecycle hooks, values and valueChanged callbacks, targets and target callbacks, outlets, action parameters, keyboard events, and controller architecture patterns.
