The index to a Book of Spells — a large, curated library of ready-made spells (skills in the SKILL.md format) gathered from many providers (Google, OpenAI, and more), covering cloud platforms, deployment, design tools, PDFs, browser automation, security, and much else. The spells are NOT preloaded — there may be thousands. Use this whenever the user asks to cast a spell, or for a spell to do something, or names a capability, provider, or tool you do not already have loaded (e.g. "cast a spell for Figma", "is there a spell for deploying?", "use the bigquery spell"), or whenever a task might be served by a specialised, ready-made spell. Casting a spell MEANS consulting this index to discover and load the right one on demand — do that first, rather than improvising. This is also the single entry point to the Book's own keystones: route here to AUTHOR a new spell (the-spellwright), to FIND or CONNECT an MCP server / external tool (the-emissary), or to INSTALL the Book into a conduit (the-tether).
How to install this Book of Spells into a conduit so its gathered skills become usable — by symlink, not by copy. Use whenever the user wants to install, set up, enable, add, or "load" the Book's spells into their agent; asks where skills go or how a conduit finds them; or asks how to keep the spells up to date. The companion to the-grimoire (which *finds* spells once they are installed): this one *shelves the Book* so the grimoire has something to find.
Find and connect an MCP server — an "Emissary of the Pact" — when the agent needs a tool, service, API, or data source it does not already have. Use when the user asks for an MCP server, to connect to or integrate an external service (Notion, GitHub, Figma, a database, Slack, a SaaS API…), asks "is there an MCP for X", "add an MCP", or sets a task that needs live tools the agent lacks. This rite DISCOVERS a server from the official MCP Registry and reputable directories and PROPOSES its connection config for the user to approve — it NEVER installs, launches, or writes credentials on its own. The companion to the-grimoire: that finds spells (inert skills); this finds Emissaries (live tool-servers).
Forge a new skill ("spell") from scratch — author a well-formed SKILL.md with discoverable frontmatter, lean progressive-disclosure structure, and optional references/scripts. Use whenever the user wants to create, write, author, draft, or scaffold a new skill or SKILL.md; package a repeatable workflow as a reusable skill; improve a skill's description so an agent reliably triggers it; or learn how skills are structured. The companion to the-grimoire: that one finds existing spells, this one makes new ones.
Generates Angular code and provides architectural guidance. Trigger when creating projects, components, or services, or for best practices on reactivity (signals, linkedSignal, resource), forms, dependency injection, routing, SSR, accessibility (ARIA), animations, styling (component styles, Tailwind CSS), testing, or CLI tooling.
Creates a new Angular app using the Angular CLI. This skill should be used whenever a user wants to create a new Angular application and contains important guidelines for how to effectively create a modern Angular application.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
