Claude's thinking hat but it says "comprehensive"

you need to link resources with your UI components and you need to wire up your resources with tools - it's odd that they chose to link the latter using a special _meta field rather than MCP embedded/linked resources but maybe I'm missing something
The image shows a code snippet written in JavaScript (or TypeScript). It defines a tool registration using server.registerTool with the name "pizza-albums". The tool has a title "Show Pizza Album" and metadata (_meta) that includes an openai/outputTemplate field pointing to "ui://widget/pizza-albums.html", along with two other fields for invocation messages: "Hand–tossing an album" and "Served a fresh album". The tool expects an input schema with one field pizzaTopping of type string. The async function returns an object with content (an array containing a text message: "Rendered a pizza album!") and an empty structuredContent object. A highlighted line draws attention to the "openai/outputTemplate": "ui://widget/pizza-albums.html", entry.

one kind of hilarious thing of trying to combine neverthrow with Cloudflare's Workflow primitives is having to write wrappers that throw..neverthrow-returned errors as Cloudflare Workflows uses caught errors to trigger retries

there's probably a better way to do this...
this is the code in the image: /** * Wraps a neverthrow Result-returning function in a WorkflowStep.do call. * Throws an Error to trigger a retry by default, or a NonRetryableError if classified as fatal. */ async function runStep<T extends Rpc.Serializable<T>>( step: WorkflowStep, name: string, config: WorkflowStepConfig, fn: () => Promise<Result<T, TugboatError>>, isFatal: (error: TugboatError) => boolean = () => false, ): Promise<T> { return await step.do<T>(name, config, async (): Promise<T> => { const result = await fn(); if (result.isOk()) { return result.value; } const error = result.error; if (isFatal(error)) { throw new NonRetryableError(error.message); } throw new Error(error.message); }); }

I raved about @cloudflare.social Workflows earlier and they're great. I just wish I could pass in a custom `onError` callback for some custom retry logic
A screenshot of a code editor displaying TypeScript code for a Cloudflare Workflow. The class TextGenerator extends WorkflowEntrypoint<Env> and defines an async run method. Inside, the code extracts a prompt from the event payload and executes step.do with retry logic. It handles errors using an onError callback, attempting to fall back to a faster model (gpt-3.5-turbo) if an AITimeoutError occurs. If this fallback also fails, it retries the original callback. The editor has a dark theme with syntax highlighting and an orange gradient border. here's the code snippet: export class TextGenerator extends WorkflowEntrypoint<Env> { async run( event: Readonly<WorkflowEvent<{ prompt: string }>>, step: WorkflowStep, ) { const { prompt } = event.payload; return await step.do( "generate-text", { retries: { limit: 3, delay: 1000, backoff: "exponential" }, onError: async (error, retry) => { if (error instanceof AITimeoutError) { // Complex model timed out, try with a faster one first try { return await generateText({ model: "gpt-3.5-turbo", prompt, timeout: 5000, }); } catch { // If faster model fails, retry with original complex model (retry is the original callback in step.do) return retry(); } } throw error; } },

Been playing with an idea: what if text editors had canvas Alt+drag interaction?

Write some text, hit CTRL+. and the paragraph 'rotates' into its alternate version. Edit either version, flip between them, but always keep reading your text naturally. Like having parallel universes for each paragraph

also, quite useful for discovering profiles (although my query in this case should be a bit more specific)

getting my hands dirty with @anthropic.com 's MCP by setting up a @bsky.app server.

Will be very helpful for queries like "what was that post I liked that was like "
