Development
Research-before-coding workflow: search npm/PyPI, MCP servers, skills, and GitHub for existing tools before writing custom code, then adopt, extend, or build. Launches the researcher agent for non-trivial needs. Use when starting a feature, adding a dependency or integration, or about to write a utility that may already exist.
Creates and maintains project context artifacts (product.md, tech-stack.md, workflow.md, tracks.md) in a `conductor/` directory. Scaffolds new projects from scratch, extracts context from existing codebases, validates artifact consistency before implementation, and synchronizes documents as the project evolves. Use when setting up a project, creating or updating product docs, managing a tech stack file, defining development workflows, tracking work units, onboarding to an existing codebase, or running project scaffolding.
Audits and rewrites a repository README so a developer who has never seen the project can tell what it is, why it beats the alternative, and run the first command inside a minute - every claim and the documented install verified against the source, the page ordered into a bail-fast funnel, badges that earn nothing pruned. Use whenever someone says "review my README", "my readme is bad", "write a README for this repo", "nobody understands what my project does", "repo first impression", "readme structure", "too many badges", or is preparing an open-source launch - even if they only call it the repo landing page. Not a profile README - use samber/developer-relations-skills@github-profile-optimization.
The base44 CLI is used for EVERYTHING related to base44 projects: resource configuration (entities, backend functions, realtime actors, ai agents), initialization and actions (resource creation, deployment), and any other operation on an existing app or workspace through the Base44 public API (settings, domains, users, members, source export). This skill is the place for learning about how to configure resources, including actors — the realtime/WebSocket primitive behind multiplayer, collaborative boards, presence and live cursors, in-room chat, and live auctions. When you plan or implement a feature, you must learn this skill
Build and publish Chrome Extensions using Manifest V3 best practices. Use this skill whenever the user asks to create, modify, debug, or understand Chrome browser extensions, add-ons, or anything involving the Chrome Extensions API. Trigger on mentions of: 'Chrome extension', 'browser extension', 'manifest.json', 'content script', 'service worker' (in browser context), 'popup' (in browser extension context), 'side panel', 'chrome.* API', 'declarativeNetRequest', 'omnibox', 'context menu' (in extension context), 'userScripts', 'user script', 'script manager', or any request to build functionality that integrates with the Chrome browser UI. Also trigger for publishing to the Chrome Web Store: 'publish extension', preparing an extension for publishing, responding to a review rejection, writing permission justifications, or drafting a privacy policy.
Retrieve up-to-date documentation for software libraries, frameworks, and components via the Context7 API. Use this skill when looking up documentation for any programming library or framework, finding code examples for specific APIs or features, verifying correct usage of library functions, or obtaining current information about library APIs that may have changed since training.
Writes or audits a teaching tutorial for a developer product — one new concept per step, checkpoints the learner can verify and resume from, guidance that fades, troubleshooting hooks, and a demonstrable skill at the end. Use whenever the user mentions a tutorial, a build-along or hands-on guide, a "learn X by building Y" article, a workshop or lab handout, a developer course lesson, or says nobody finishes their tutorial — even if they just say "write a guide that teaches this". Do NOT use for a zero-to-first-success quickstart (samber/developer-relations-skills@developer-quickstart-guide) or a video script (samber/developer-relations-skills@technical-video-script).
Designs an issue and pull-request triage system a maintainer team can sustain: response targets sized against real capacity, label taxonomy, intake cuts through structured forms and off-tracker routing, a separate security-report path, triage duty assignment, and closing, staleness, and volume-gating policies. Use whenever someone says “our issue tracker is out of control,” “design an issue triage process,” “set up labels for our repo,” “we have 900 open issues,” “should we run a stale bot,” “PR backlog nobody reviews,” “triage rotation,” or “we are drowning in AI-generated reports”—even if they only say maintenance is overwhelming. Not for good-first-issue curation; use samber/developer-relations-skills@oss-contributor-onboarding.
Engineers a technical demo so it survives the stage - risk triage, the fidelity tier it should run at, independently enterable checkpoints, a one-command environment reset, offline mode, a recorded fallback and rehearsed recovery lines, shipped as a demo runbook with a pre-flight checklist. Use whenever the user mentions a live demo, live coding, demo reliability or a fallback plan, "my demo broke on stage", whether to demo live or pre-record, a demo environment reset, a clean demo laptop, a demo profile or a panic button, or is preparing a talk, workshop, webinar or launch stream containing a demo - even if they only say "I'm nervous about the demo" or "what if I share the wrong screen". Not the talk's structure - use samber/developer-relations-skills@tech-talk-outline.
Makes SDK, API or protocol documentation something a coding agent can integrate from unattended - crawler access, machine-readable entry points (llms.txt, markdown endpoints, OpenAPI and JSON Schema files), self-contained copy-paste-safe pages, and a measured first-attempt agent success rate. Use whenever the user mentions agent-readable or AI-ready docs, agent experience or AX, llms.txt or llms-full.txt, docs for coding agents, agents inventing API calls that do not exist, or asks whether an agent could wire up their SDK from the docs alone - even if they never say "agent". Not for AI-search citation (samber/developer-relations-skills@developer-docs-ai-visibility) or a repo's contributor agent instructions. For human docs architecture use samber/developer-relations-skills@developer-docs-structure-audit.
Writes or edits a technical blog post a skeptical developer audience will believe: the right post pattern, evidence behind every claim, published trade-offs and limitations, runnable snippets, and no marketing voice. Use whenever the user wants an engineering blog post, a technical article, a “how we built it” or “we rewrote it in X” story, a debugging write-up, a public postmortem, a benchmark post, or a product post that must not read as marketing, and when they ask to review, edit, de-jargon, or de-market an existing technical draft—even if they only call it “the article.” Not a teaching tutorial—use samber/developer-relations-skills@developer-tutorial. Not release notes, a migration guide, a case study, or a talk.
Render videos from React/Remotion component code via inference.sh. Pass TSX code, get MP4. Supports all Remotion APIs: useCurrentFrame, useVideoConfig, spring, interpolate, AbsoluteFill, Sequence. Configurable resolution, FPS, duration, codec. Use for: programmatic video generation, animated graphics, motion design, data-driven videos, React animations to video. Triggers: remotion, render video from code, tsx to video, react video, programmatic video, remotion render, code to video, animated video, motion graphics code, react animation video
Choose when the user needs **Shopify CLI** to run or fix something now: validate app or extension config on disk (`shopify.app.toml`, `shopify.app.<name>.toml`, `shopify.extension.toml`); review or audit an app's code for security vulnerabilities; run or troubleshoot store workflows (`shopify store auth`, `shopify store execute`); or perform explicit store-scoped reads/writes on a named store domain (for example, show/list/find the first 10 products on my store at `foo.myshopify.com`, or inventory and product changes by handle, SKU, or location name). Emphasize **commands and operational steps**, not only authoring GraphQL. Skip for API-only understanding or codegen with no CLI execution, and skip for brand-new merchant asks to start a Shopify store or try Shopify before they have an account. Examples: validate configuration before deploy; run an existing query via CLI; show the first 10 products on `foo.myshopify.com`; missing `shopify store execute`.
Writes or audits the migration guide for a breaking change — what breaks, ordered by blast radius, with a detection signal and before/after code per entry, a deprecation timeline, the codemod's coverage boundary, and verification by a cold upgrade of a real project. Use whenever someone mentions a migration guide, an upgrade guide, a breaking-changes page, a major version bump, “how do we tell users about v3”, an API version cutover, a deprecation or sunset notice, or a codemod or compat build — even if they only say they are shipping v2. Covers libraries, SDKs, CLIs, frameworks, hosted APIs and schema runbooks. Not release notes — use samber/developer-relations-skills@changelog-writing.
Turns raw commits, pull requests and tickets into release notes developers actually read - a scannable record of what shipped, what it means in practice, and what breaks. Use whenever the user mentions a changelog, CHANGELOG.md, release notes, a GitHub release body for a tag, a hosted "what's new" page, app-store release notes, Keep a Changelog, or Common Changelog, or asks what to write for a release they just cut - even when the commit history is messy and follows no commit convention. Not for version bumping, tagging or publishing pipelines. Do NOT use for a full breaking-change upgrade guide - use samber/developer-relations-skills@version-migration-guide; for a narrative release post use samber/developer-relations-skills@engineering-blog-post.
Creates smooth animations and micro-interactions using Framer Motion including page transitions, gestures, scroll-based animations, and orchestrated sequences. Use when users request "add animation", "framer motion", "page transition", "animate component", or "micro-interactions".
Turns support tickets, issue history and error telemetry into troubleshooting and error-reference pages a developer finds by pasting the error string - symptom, conditions, cause, fix and verification entries, an error-code catalog generated from one source of truth, and fixes wired back into the product's own error output. Use whenever the user mentions troubleshooting docs, documenting error codes, error message pages, a known-issues page, building an FAQ from support tickets, or "we answer the same question every week" - even if they only say "users keep hitting this error". Not for debugging a live incident. Do NOT use for docs search ranking - use samber/developer-relations-skills@docs-seo.
Guidance on writing fast, robust, modern Svelte code. Load this skill whenever in a Svelte project and asked to write/edit or analyze a Svelte component or module. Covers reactivity, event handling, styling, integration with libraries and more.
Defines the policy every code sample in developer documentation must meet and audits an existing sample corpus against it, returning a ranked fix queue. Use whenever the user mentions docs code samples, code snippets in documentation, runnable examples, examples that no longer compile, copy-paste failures, snippet drift after an API change, testing docs examples in CI, SDK snippet parity across languages, sample maintenance ownership, or asks why the examples in their docs do not work—even if they only say the docs are broken. Covers sample anatomy, copy-paste and security safety, execution tiers, single-sourcing from tested code, and language parity. Not for writing a quickstart page—use samber/developer-relations-skills@developer-quickstart-guide.
Migrate a codebase from the Runpod GraphQL API or REST v1 to REST v2 — inventory which parts use which API version, rewrite the call sites, flag breaking changes, and verify. Use when someone asks to move to v2, asks what v2 would change, or asks which Runpod API their code is on. For managing infrastructure rather than migrating code, use runpod-mcp or runpodctl.
All code changes must follow the guidance documented in the repository. Before filing an issue, creating a branch or commits, or creating a pull request (PR), search for the correct steps. Use this skill when asked to create an issue, write commit messages, push code, or create a PR.
Execute Python code in a safe sandboxed environment via [inference.sh](https://inference.sh). Pre-installed: NumPy, Pandas, Matplotlib, requests, BeautifulSoup, Selenium, Playwright, MoviePy, Pillow, OpenCV, trimesh, and 100+ more libraries.

Triggers: python, execute code, run script, web scraping, data analysis, image processing, video editing, 3D models, automation, pandas, matplotlib
Build your app's primary user interface embedded in the Shopify admin using the **iframe** model — a web app you host yourself, rendered with `@shopify/polaris-types` and App Bridge. Covers the Intents API (`shopify.intents.invoke`) for launching native workflows from App Home. For the Shopify-hosted `admin.app.home.render` extension target, use **`polaris-admin-extensions`** instead. If the prompt just mentions `Polaris` and you can't tell based on the context which API is meant, assume it refers to this API.
HeroUI Native component library for React Native (Tailwind v4 via Uniwind). Use when building mobile UIs with HeroUI Native — creating Buttons, Cards, TextFields, Dialogs; installing heroui-native; configuring dark/light themes; or fetching component docs. Keywords: HeroUI Native, heroui-native, React Native UI, Uniwind, mobile components
How agentmemory is built, the iii engine primitives it runs on, its storage model, ports, and the viewer. Use when reasoning about how memory is stored or retrieved end to end, when extending the system, or when answering how agentmemory works under the hood.
Pure API reference for reddapi.dev—authentication, all endpoints (vector search, semantic search, trends, subreddit lookup), request parameters, response schemas, and error codes, with no research-workflow framing. Use when the user wants raw endpoint documentation, is debugging a reddapi.dev integration, needs exact request/response field names, or asks for “reddapi API reference,” “reddapi.dev endpoints,” or “reddapi error codes.” For guided research workflows and query playbooks, see reddit-research. For B2B lead scoring, see reddit-leads.
Implement saga patterns for distributed transactions and cross-aggregate workflows. Use this skill when implementing distributed transactions across microservices where 2PC is unavailable, designing compensating actions for failed order workflows that span inventory, payment, and shipping services, building event-driven saga coordinators for travel booking systems that must roll back hotel, flight, and car rental reservations atomically, or debugging stuck saga states in production where compensation steps never complete.

Available APIs: Discount, Cart and Checkout Validation, Cart Transform, Pickup Point Delivery Option Generator, Delivery Customization, Fulfillment Constraints, Local Pickup Delivery Option Generator, Order Routing Location Rule, Payment Customization
Create, modify, debug, and deploy Apify Actors, and write their input and output schemas. Use when building an Actor from scratch, changing or troubleshooting Actor code, generating or updating .actor schema files, or pushing an Actor to the Apify platform. To wrap an existing non-Actor project, use apify-actorization instead
Run the full Django verification loop — environment check, mypy/ruff/black linting, migration safety, pytest with coverage targets, pip-audit and bandit security scans, settings and logging review, and diff review — producing a phased pass/fail report before release or PR. Use when preparing a Django pull request, validating migrations or coverage, or running pre-deploy readiness checks.
Idiomatic Kotlin patterns, best practices, and conventions for building robust, efficient, maintainable Kotlin applications with coroutines, null safety, and DSL builders. Use when writing or reviewing Kotlin code and idiomatic structure or null safety is in question.
SDFormat/SDF model and world authoring, validation, and simulator handoff. Use for `.sdf` files, SDFormat XML, models, worlds, links, joints, poses, frames, inertials, visual/collision geometry, mesh URIs, sensors, lights, physics, plugins, includes, Gazebo, static SDF review, or simulator-specific metadata. Do not use for signed-distance-field geometry. Open and visually review existing SDF files in CAD Viewer.
Next.js 16+ and Turbopack guidance — incremental Rust bundling, file-system caching, faster dev startup and HMR, Turbopack vs webpack tradeoffs, and the middleware.ts to proxy.ts filename change. Use when developing or debugging Next.js 16+ apps, diagnosing slow dev startup or hot reload, choosing between bundlers, or reviewing middleware/proxy file naming.
