Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

The Vendo agent loop: streaming, tool-calling, context engineering — BYO ai-SDK LanguageModel, guard-bound tools, thread persistence via the store seam.

Readme

@vendoai/agent

Runs Vendo's streaming, tool-calling conversation loop against any AI SDK LanguageModel, with persisted threads and guard-bound tools.

Threads persist through the composed store; without a configured store the agent defaults to core's in-memory reference StoreAdapter through the same single path. agent.evictSubject(subject) list-and-deletes the subject's thread rows — the umbrella calls it for every subject the store's idle sweep returns (usually a no-op, since the sweep's erase cascade already removed those rows).

stream({ signal }) cancels a turn: the in-flight provider call aborts, no further step starts, and the thread stays consistent and resumable (the umbrella passes the request's own signal, so client disconnect cancels the loop). The per-turn step cap is context.maxSteps (default 20); exhausting it streams a renderable data-vendo-step-limit part instead of ending silently.

Approvals a conversation walks away from resolve guard-side: a fresh user turn marks undecided asks abandoned in the thread and denies them through guard.abandonApprovals when the guard provides it. Client upserts are validated — a new message must be user-role, and an existing assistant message may change only by answering a pending approval.
