Development
Use the JetBrains IDE MCP Server (IntelliJ IDEA 2025.2+) for IDE-backed indexing, inspections, symbol info, project file operations, and structural refactoring. Use it when you need exact project-aware analysis or safe IDE refactors, rather than broad semantic repository discovery.
Use for Lanhu (蓝湖) UI design handoffs and lanhuapp.com design project links: list design screens, inspect screenshots and HTML/CSS specs, extract design tokens, download slices/assets, or implement UI. Trigger when the request explicitly mentions 蓝湖, Lanhu, lanhuapp.com, or the bundled Lanhu scripts. Do not use for standalone Figma/Sketch files, generic UI implementation, PRD/Axure docId links, or image editing unrelated to Lanhu.
Use when creating, applying, or validating overlay files including x-speakeasy extensions. Covers overlay syntax, JSONPath targeting, retries, pagination, naming, grouping, open enums, global headers, custom security. Triggers on "create overlay", "apply overlay", "overlay file", "x-speakeasy", "add extension", "configure retries", "add pagination", "overlay for retries".
DEPRECATED — superseded by tree-sitting. This skill generated persistent _MAP.md files; tree-sitting does the same AST extraction at runtime (~700ms for 250 files) with no artifact to write, commit, or keep in sync. Use tree-sitting for "map this codebase", "explore repo", "understand structure", or any code navigation task. The final working version is archived at release mapping-codebases-v0.8.0.
Operate Milvus vector database with pymilvus Python SDK. Use when the user wants to connect to Milvus, create collections, insert vectors, perform similarity search, hybrid search, full-text search, manage indexes, partitions, databases, or RBAC via Python code.
Anti-slop design skill for BUILDING React Native / Expo apps (iOS, Android, web). Commits to an App Read and Nav Read before writing code; ships screens, navigation, and motion that do not look AI-generated. Use when creating new screens, features, or apps in React Native. For auditing an existing app use mobile-design-review; for upgrading existing screens use mobile-redesign-screen or mobile-redesign-app; for navigation planning alone use mobile-nav-plan; for tokens/theming use mobile-design-system.
Best-practice guide for authoring a Muxy extension — how it should look and behave so it reads as a native part of the app. Covers theming (follow the theme, never hardcode colors), the sizing scale, and which surface to use. Mechanics (manifest fields, permissions, the window.muxy API) live in the linked docs.
Always use this skill when the user wants to explore Openfort documentation, browse SDK source code, or use Openfort MCP tools. This is the general-purpose Openfort platform skill — use it for documentation lookup, source code navigation, and CLI operations. For building with embedded wallets, use the openfort-embedded-wallet skill. For backend wallets, use the openfort-backend-wallets skill. Trigger on: "Openfort docs", "search Openfort", "Openfort source code", "openfort CLI", "MCP tools", "Openfort SDK source", or general Openfort platform questions.
Use the public `orca` CLI to operate Orca-managed worktrees, folder contexts, terminals, repos, automations, artifacts, worktree comments, and the browser embedded inside the Orca app. Use when the user says "$orca-cli", "use orca cli", "Orca worktree", "child worktree", "cardStatus", "spawn codex/claude in a worktree", "read/wait/send Orca terminal", "terminal send", "full handoff", "handover", "give this to another agent", "another worktree", "Orca browser", "orca artifacts", "share HTML/Markdown", "public artifact link", or "control the browser inside Orca". Prefer this over raw `git worktree`, ad hoc PTYs, Playwright, or Computer Use when the task touches Orca-managed state. Use Computer Use for browser windows, webviews, or desktop UI outside Orca's embedded browser.
Pino (fast JSON structured logger for Node.js, the standard logger for Fastify) reference. logger, child logger, log levels (info / warn / error / debug / trace), transport, pretty print (pino-pretty), redaction (masking sensitive data), serializers, async / sync logging, file output, structured logging.
Use when the DSH host itself has been upgraded (or is about to be) and the whole installed fleet of Web/client plugins must be checked against the new host - one or more surfaces broke, vanished, or need their compatibility re-verified and re-released. Also use after a host upgrade to sweep for silent breaks before the user reports them, and to run the per-plugin fix/release loop (branch, bump, changelog, tag, mirrors).
Write or critique a user story—a small unit of user value framed around a real persona’s need, not a restated task. Frame stories around who, what, and why; keep them INVEST-compliant and testable; map them across the journey; and avoid stories that add no clarity. Apply the always-true core and gate context-dependent decisions (strict formula vs. free form, whether to write a story at all, acceptance-criteria depth, splitting into a map, communication framing). Trigger when asked to write user stories, turn a persona or need into stories, frame requirements as stories, build a story map, apply INVEST, or review or strengthen existing stories
Turn a PRD into a multi-phase implementation plan using tracer-bullet vertical slices, saved as a local Markdown file in ./docs/. Use when user wants to break down a PRD, create an implementation plan, plan phases from a PRD, or mentions "tracer bullets".
Manages software projects end-to-end — decomposing work into tasks, tracking progress across sprints, generating status reports, and integrating with tools like Jira, Linear, GitHub Issues, and Trello. Use when the user requests project management or provides relevant inputs for this workflow.
Build React Native 0.76+ apps with Expo SDK 52. Covers mandatory New Architecture (0.82+), React 19 changes (propTypes/forwardRef removal), new CSS (display: contents, mixBlendMode, outline), Swift iOS template, and DevTools migration. Use when: building Expo apps, migrating to New Architecture, or troubleshooting "Fabric component not found", "propTypes not a function", "TurboModule not registered", or Swift AppDelegate errors.
Design, automate, and operate end-to-end software releases: release process models and pipelines (trunk-based development, CD stages, release trains), progressive delivery and feature flags, versioning and artifact management (SemVer, conventional commits, changelogs, SBOM/provenance), readiness and quality gates, rollback and recovery planning, change-management and audit compliance (SOC 2, SOX, PCI), DORA metrics, and multi-team release coordination. Do not use for application feature implementation (backend-engineering/frontend-engineering), production incident root-cause debugging or on-call/SLO operations (systematic-debugging / site-reliability-engineering), security implementation or threat modeling (secure-software-engineering), or internal developer platform construction (platform-engineering).
Reverse-engineers a UI animation from a screen recording. Extracts frames with ffmpeg, tracks motion per frame with OpenCV, fits easing and spring curves, annotates choreography (leads, lags, over-stretch), and emits CSS, Motion/Framer Motion, SwiftUI, React Native, or UIKit code plus a handoff motion spec. Use when the user shares or uploads a screen recording or video of a UI animation, or asks to "reverse engineer this animation", "recreate this animation", "match this easing", "extract the animation curve", "figure out the spring from this video", "copy this transition from a video", "how does this animation work", or "reproduce this motion". For designing new motion from scratch or reviewing motion code, use ui-animation instead.
Build, generate, test, package, and troubleshoot shared Rust components and cross-platform bindings with Mozilla UniFFI. Use automatically when users want to write business logic once in Rust and call or reuse it from Swift, iOS, macOS, Kotlin, Android, JVM, Python, Ruby, JavaScript, browsers, desktop apps, or multiple platforms—even when they do not mention UniFFI; when they ask to bridge, expose, connect, or share Rust with Swift/Kotlin/Android/iOS; or when they need procedural-macro versus UDL selection, records, enums, errors, objects, traits, callbacks, custom types, uniffi.toml, uniffi-bindgen, async exports, generated-binding diagnostics, native-library loading, packaging, ABI, or upgrades. Verify that the locked UniFFI release supports each requested target; route hand-written C ABI work to rust-unsafe-ffi.
