Triggers on Tauri, src-tauri, invoke, emit, capabilities.json.
Writing developer-facing prose that can be skimmed first and trusted enough to finish — READMEs, guides, tutorials, reference docs, proposals, PR descriptions, release notes. Load before drafting, rewriting, restructuring, or editing technical documents, when a doc reads as a wall of text, claims need receipts, or docs must serve AI agents. Covers reader-first structure, falsifiable claims, docs-as-behavior verification, and agent-readable reference shape. For sentence-level voice or generic AI-shaped prose use clarity; for plain English, lay readers, translation, or ASD-STE100 use simple-english; for recording a learning use expectations; for diagrams use diagrams; for API semantics use api-design; for CLI help use cli-design.
Coordinate documentation updates alongside code changes. Use when preparing the `.docs/` checkout, creating a matching docs branch, opening a `tenzir/content` documentation pull request, or cross-linking docs and code PRs. Also use when the user mentions "update the docs", "docs PR", ".docs/", or when a code change affects user-facing behavior that should be reflected in the documentation on tenzir.com.

Expose an AG2 `Agent` over the AG-UI protocol so a frontend (CopilotKit, custom React/Next.js, or any AG-UI client) can stream responses (text and reasoning), render tool calls, sync shared state, and track sub-task steps. Wraps the agent with `AGUIStream(agent)` and mounts it in FastAPI via `stream.dispatch(...)` or `stream.build_asgi()`. Use when the user wants a web frontend in front of an AG2 agent rather than a CLI / script.
Map of AG2 capabilities and which sibling skill to reach for. Load first when the user mentions building with AG2 (ag2) but the specific feature isn't yet clear — agents, tools, model config, delegation, memory, observers, structured output, HITL, AG-UI, MCP server hosting, A2A protocol, realtime voice, telemetry, testing, or evaluation.

Add GSAP-driven WebGL to a site without restyling it, on one shared OGL renderer and canvas per document. Image planes track each img for a hover lens, scroll-velocity wave, wipe, glitch, dissolve, pixelation, and ripple. Framed views draw in an element's box: a camera flight through a 3D spiral of images, GPU particles morphing between shapes, a liquid image, and liquid-metal drops that melt into a word or pour down a page. GSAP tweens shader uniforms. The real img, or a poster img for a view, stays the accessible content and the fallback when WebGL is missing, the context is lost, an image lacks CORS, or motion is reduced. Use for WebGL image effects, shader hover, 3D scroll flights, particle morphs, liquid hover, uniform tweens, or keeping a canvas alive across routes. Pair with the matching GSAP framework skill for lifecycle timing. Not for glTF models, physics, DOM-only effects (use animaxxing), branding, or GSAP API questions.
Reverse engineer, debloat, de-ad, patch, or re-sign Android APKs, and analyze their runtime and server-side behaviour. Use for an .apk/.aab/.dex/.so sample, smali or dex patching, Frida hooking, repacking, ad or SDK removal, API probing, or deciding whether a client-side patch can work. Covers recon, anti-tamper, membership limits, surgical dex patching, repack pitfalls, device setup, and a failure catalogue.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
