Guides integration of the Horizon Platform SDK for Meta VR and Horizon OS Unity/C# apps: achievements, IAP, users, leaderboards, challenges, presence, notifications, abuse reporting, entitlements, asset files, application lifecycle, consent, device integrity, language packs, user age categories, and rate and review. Covers setup, initialization, API usage, data types, error handling, and best practices for all 18 public platform SDK packages
Guide for Infisical access control and governance — org and project roles, custom roles with subject/action permissions, granular secret permissions that separate describing a secret from reading its value, attribute-based access control (ABAC) driven by user metadata and machine identity attributes, additional privileges, assume-privilege, temporary (time-bound) access, access requests, change-approval and access-approval policies, and audit logs including streaming to Splunk, Datadog, Azure, Cribl, Sumo Logic, or a custom webhook. Use this skill when someone asks about: Infisical roles and permissions, custom roles, least privilege for secrets, letting someone see a secret exists without reading it, ABAC, temporary access, approval workflows for secret changes, access requests, audit logs, or streaming audit events to a SIEM. For what a principal can do once inside. Not for connecting an identity provider for login or SCIM (infisical-sso), nor for machine identity auth methods (infisical-setup).
Creates, validates, formats, and modifies Infrahub schema YAML files — nodes, generics, attributes, relationships, and extensions. Also checks the Infrahub Marketplace for an existing published schema to reuse before modelling a domain from scratch. TRIGGER when: designing data models, adding schema nodes, validating schema definitions, planning schema migrations, modifying or extending an existing schema, changing an attribute or relationship on a node kind, debugging why a schema fails to load or a migration is rejected, checking the marketplace for an off-the-shelf schema, modeling file objects / attachments / uploads (PDFs, images, certificates, documents), formatting schema files, canonicalising schema key order, or running `infrahubctl schema format` (including as a CI gate). DO NOT TRIGGER when: populating or editing object data files (use infrahub-managing-objects), writing checks/generators/transforms, querying live data, planning an Infrahub version upgrade (use infrahub-planning-upgrades)
Creates, modifies and debugs Infrahub transforms that convert data into JSON, text, CSV, or device configs using Python or Jinja2 templates, with YAML-driven tests. TRIGGER when: building config generation, data export, format conversion, Jinja2 templates, artifact pipelines, writing or running tests for a transform, modifying or extending an existing transform or template, debugging why a transform renders the wrong output or an artifact fails to generate. DO NOT TRIGGER when: designing schemas, writing validation checks, creating generators, querying live data
Bring a project's formal verification back in line with the code after the code changes: find the commits that touched verified code, update the model, harness, or properties to describe the code as it is now, rerun, and say whether each failure is drift in the verification or a bug in the code. Use for /maintain-formal-verification-skill, \"is the model still true to the code\", or after merges and refactors that touched verified code without rechecking it.
Memory retrieval internals: knowledge graph orchestration with entity extraction, natural language query parsing, deduplication (>85% similarity), and cross-reference boosting over unified recency, relevance, and authority ranking. Use when designing or debugging how memory search itself works. Everyday lookups belong to memory; entry storage to remember; consolidation to dream.
Expert guidance for writing fast, maintainable Minitest tests in Rails applications. Use when writing tests, converting from RSpec, debugging test failures, improving test performance, or following testing best practices. Covers model tests, policy tests, request tests, system tests, fixtures, and TDD workflows.
Vision, audio, video generation, and multimodal LLM integration patterns. Use when processing images, transcribing audio, generating speech, generating AI video (Kling v3, Sora 2, Veo 3.1 std/lite/fast, Runway Gen-4.5 via `gen4_turbo`), or building multimodal AI pipelines
Next.js 16 App Router performance, caching, server components, server actions, routing, and codebase-hygiene best practices — plus a category-major review/refactor algorithm with codebase-level (remove/dedup/reuse) findings. This skill should be used when writing Next.js 16 App Router code, configuring caching with 'use cache' or the previous fetch-cache model, building Server Components, setting up parallel/intercepting routes, configuring next.config OR proxy.ts, OR auditing/refactoring a Next.js codebase (single file or whole repo). This skill does NOT cover generic React 19 patterns (use vercel-react) or non-Next.js server rendering.
Guide for implementing Obsidian knowledge management - vault operations, plugin development, URI scheme automation, markdown extensions, and Local REST API integration. Use when working with Obsidian vaults, creating plugins, automating note workflows, querying notes via API, or implementing knowledge graph features.
Use when the user explicitly wants autonomous progress without routine clarification stops: "plow ahead", "do not stop", "use your best judgment", "keep going until done", "finish while I am away", "do not ask questions unless truly blocked", or similar. Convert ordinary ambiguity into stated assumptions, proceed through implementation and validation, stop only for true blockers, and end with a clear recap of decisions, changes, verification, and residual risk.
Every Seats.aero Partner API endpoint, plus a local award-availability store that tells you what is new, what is still live, and where your miles reach nonstop. Trigger phrases: `find award seats to Tokyo in business`, `what award availability is new since yesterday`, `where can my miles take me nonstop from JFK`, `is this award seat still available before I book`, `show me the award calendar for united to Europe`, `use seats-aero`, `run seats-aero`.
Define user-facing product behavior from validated evidence and approved scope. Use for information architecture, task flows, state and recovery models, interface contracts, usability-study plans, interaction-pattern tradeoffs, AI recommendations and generated outputs, uncertainty, human control, feedback, or engineering UX handoffs. Use after product discovery and product decisions; route WCAG/ARIA conformance work to web-accessibility and formal software specifications to spec-driven-development. Do not use this skill for unrelated requests; route to the nearest named specialist.
Use the standalone qiaomu-bento-ppt skill to create or edit self-contained qiaomu-style bento presentations as .bento.html files from briefs, notes, reports, URLs, data, or existing bento decks. Use this skill when the user explicitly asks for bento/slides, a .bento.html deck, an offline-editable single-file HTML presentation, or invokes qiaomu-bento-ppt. It uses a proposal-first presentation workflow, includes a pinned official bento shell and authoring references, builds through the plaintext #bento-doc contract without requiring the original bento repository, and validates structure, identity, shell integrity, visual heuristics, and rollback boundaries. Do not use for conventional .pptx delivery, generic bento source development, or bento/spaces and bento/dash work.
Replicate and validate a GitHub issue by spinning up Archon, analyzing the issue, and systematically testing all described symptoms using browser automation. Use when: User wants to reproduce a bug, validate a GitHub issue, confirm a reported problem, or investigate whether an issue is real before working on a fix. Triggers: "replicate issue", "reproduce issue", "validate issue", "confirm bug", "test issue", "can you reproduce", "try to replicate", "verify the bug". Capability: Checks out main, pulls latest, starts Archon, reads the GitHub issue, then uses agent-browser to systematically test every symptom and produce a findings report. NOT for: Fixing issues (use /archon or /exp-piv-loop:fix-issue), general UI testing (use /validate-ui).
Design Roblox worlds, levels, hubs, zones, biomes, obbies, arenas, and exploration spaces. Use for spatial layout, landmarks, player flow, spawn design, objective placement, onboarding paths, traversal, sightlines, social spaces, performance-aware world layout, and guiding players without text.
Audit one page for search intent, content quality, E-E-A-T, metadata, schema, links, and technical SEO. Use public page inspection and optional connected Search Console data or supplied reports. State missing evidence. Use for single-page SEO audits, URL reviews, landing-page content quality, or on-page fixes.
Convert an existing codebase in the current working directory into a ShinkaEvolve task directory by snapshotting the relevant code, adding evolve blocks, and generating `evaluate.py` plus Shinka runner/config files. Use when the user wants to optimize existing code with Shinka instead of creating a brand-new task from a natural-language description.
How to work in a Software Lifecycle project (the `software-lifecycle` starter pack): proposals → decisions → specs → postmortems, plus guides. Read when the project has these folders, or when asked how this project is organized. Carries the doc lifecycle, status flows, and per-folder agent behaviors so that guidance does not live inside template bodies or folder descriptions. The five workflows — frame a proposal, write a spec, record a decision, write a postmortem, review a design — each ship as their own sibling skill in this pack. Complements the platform `open-knowledge` skill; does not replace it
TanStack AI (alpha) provides provider-agnostic, type-safe chat with streaming for OpenAI, Anthropic, Gemini, and Ollama. Use for chat APIs, React/Solid frontends with useChat/ChatClient, isomorphic tools, tool approval flows, agent loops, multimodal inputs, or troubleshooting streaming and tool definitions.
Wrap any HTML artifact with a side panel of live, parameterized controls — accent color, type scale, density, motion, theme — that rewrite CSS custom properties in real time and persist to localStorage. Lets the user explore variants of a design without re-prompting the agent. Use when the brief asks for "variants", "side-by-side options", "tweak this", "let me adjust", "live knobs", or "实时调参".
Analyzes urban development through planning lens using zoning, land use, comprehensive planning, and transit-oriented development frameworks. Provides insights on spatial organization, infrastructure, sustainability, and livability. Use when: Urban development projects, zoning decisions, transportation planning, sustainability initiatives. Evaluates: Land use patterns, density, accessibility, environmental impact, community needs.
Entry point for open-source intelligence, investigation and verification work. Routes any identifier — a name, phone number, email address, username, domain, company, photo, crypto address, tail number or IMO — to the right investigation workflow, after setting an authorised scope. Use when asked to investigate, research, verify, vet, check out, look up, background-check, trace, attribute or find someone or something; when a request involves due diligence, KYC or KYB, counterparty or vendor risk, sanctions and PEP screening, AML, fraud, business email compromise, verifying a supplier before payment, recruitment or marketplace scams, insider threat, executive protection, attack-surface review, journalism or fact-checking; or when someone asks “who is this”, “who owns this”, “is this real”, “where did this come from” or “where do I start”.

Determine which workflow recipe to run. Invoke before any of these: audits (docs vs. code, design vs. code, root cause, project direction); triaging or resolving review findings; PR review comments; turning a feature brief into a plan; getting a second-model verdict on a plan; implementing a spec; research or price comparisons that may take several rounds; “跑一輪審查,” “幫我找資料／比價,” “幫我 plan,” or “把 findings 處理掉.” After any audit finishes, invoke again to route its findings to triage. Invoke even if there is only a 1% chance it applies.
Generate viewable HTML or a complete spec for host consumption with VChart, modify and diagnose chart configurations, recreate styles from screenshots, and support React-VChart and chart interactions. Use for VChart chart generation, configuration, troubleshooting, and application integration.
Use this skill to generate a wireframe, mockup, or low-fidelity clickable prototype of any web UI. Invoke whenever the user mentions wireframing, mocking up, prototyping, or sketching out a UI — including phrases like "lo-fi prototype", "rough layout", "Balsamiq-style", "hand-drawn UI", "clickable prototype", "sketch the screens", "visualize the flow", or "show what the app would look like". Also use when the user wants to ideate before writing production code, prepare a concept for stakeholders, run a design sprint, or asks about react-doodle-icons. Produces a self-contained SPA with sketchy hand-drawn aesthetics: wired-elements interactive components, graph-paper background, and doodle icons.
Use when building widgets that extend Wix dashboard pages for first-party business apps. Triggers include dashboard plugin, dashboard slot, extend dashboard page, Wix Stores plugin, Wix Bookings plugin, Wix Blog plugin, observeState, dashboard widget. Do NOT use for standalone dashboard pages (use wix-cli-dashboard-page) or site-facing UI (use site widgets/site plugins).
Handle Wix Stores Catalog V1 and V3 SDK compatibility. Use when building any integration that interacts with Wix Stores products, inventory, orders, or collections. Triggers include Wix Stores, products API, inventory API, catalog version, productsV3, V1 vs V3, store products, queryProducts, getProduct.
Cloud laboratory platform for automated protein testing and validation. Use when designing proteins and needing experimental validation including binding assays, expression testing, thermostability measurements, enzyme activity assays, or protein sequence optimization. Also use for submitting experiments via API, tracking experiment status, downloading results, optimizing protein sequences for better expression using computational tools (NetSolP, SoluProt, SolubleMPNN, ESM), or managing protein design workflows with wet-lab validation.
Develop a creative idea and structure a video script optimized for AI generation, following PJ Ace's 8-second scene method. Use when: **Starting an AI video ad** — turn a raw idea into a structured script; **Creating social media video content** — TikTok, Reels, YouTube Shorts; **Developing a campaign concept** — before storyboarding; **Pitching a video idea** — present a concept to a client or team; **Adapting a message...
Prevent [defensive writing] throughout the entire process of paper writing, revision, compression and experiment organization. Treat the paper as an academic launch event, not a project summary, experiment log or self-audit report: identify the most publishable value of the work and build the most favorable, complete and persuasive narrative around it. No even-handed presentation, no volunteering weaknesses, no blow-by-blow experiment logs, no attacking yourself on the reviewer's behalf. Trigger words: paper polishing, paper revision, writing the abstract, writing the introduction, writing the conclusion, compressing a paper, rebuttal, responding to reviewer comments, organizing experiments, AI flavor in papers, defensive writing, feeling insecure.
