Creating Plugins For LLMs
Those are conversational experiences that extend AI assistants through tools and custom UI views. They're built as MCP servers invoked during conversations.
⚠️ The app is consumed by two users at once: the human and the AI Assistant LLM. They collaborate through the view—the human interacts with it, the LLM sees its state. Internalize this before writing code: the view is your shared surface.
SPEC.md keeps track of the app's requirements and design decisions. Keep it up to date as you work on the app.
No SPEC.md? → Read discover.md [blocked] first. Nothing else until SPEC.md exists.
SPEC.md exists? → Read SPEC.md, then follow architecture.md [blocked] to design the change. Update SPEC.md, then read the relevant Implementation references below before writing code.
Migrating from Skybridge < 0.36.x? → Read migrate-to-v1.md [blocked] first. Users may reference skybridge >= 0.36.x as v1.
Migrating from Skybridge 1.x to 2.x? → Fetch the v2.0.0 release notes first and follow them.
Building an ecommerce app? → Read ecommerce.md [blocked] first.
Setup
- Copy template → copy-template.md [blocked]: when starting a new project with ready SPEC.md
- Run locally → run-locally.md [blocked]: when ready to test, need dev server, use devtools to render views or connect to ChatGPT/Claude
- Evals → evals.md [blocked]: when checking that a real model reaches the right tools from natural prompts, in a test
Architecture
Design or evolve UX flows and API shape → architecture.md [blocked]
Implementation
- Fetch and render data → fetch-and-render-data.md [blocked]: when implementing server handlers and view data fetching
- State and context → state-and-context.md [blocked]: when persisting view UI state and updating LLM context
- Prompt LLM → prompt-llm.md [blocked]: when view needs to trigger LLM response
- UI guidelines → ui-guidelines.md [blocked]: display modes, layout constraints, theme, device, and locale
- External links → open-external-links.md [blocked]: when redirecting to external URLs or setting "open in app" target
- Download file → download-file.md [blocked]: when saving content to the user's filesystem
- OAuth → oauth.md [blocked]: when tools need user authentication to access user-specific data
- CSP → csp.md [blocked]: when declaring allowed domains for fetch, assets, redirects, or iframes
Deploy
