just released a small update to jj-hunk - programmatic hunk selector for your jj-using agent New: -r flag. Split any revision, not just your working copy. support for YAML specs stable hunk IDs you can install it with: cargo install jj-hunk npx skills add laulauland/jj-hunk

added revision search to Tatami that supports search by change id, keywords in messages, and also niche but fun stuff like revset queries (you can query "pol-" to go to the parent of "pol" revision)

getting to the point where I'm really liking the experience of Tatami - a GUI I'm building for jj - uses jjui/vim-style keybindings for navigation - has overview and detail screens - fast! Uses @tanstack.com DB to interface via @tauri.app IPC - uses diffs.com of course

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
