i love prompting for a full walkthrough of a flow i.e here i had it show me all of the steps involved in oauth and found redundant steps, layout shift, and some weird ui state agents don't have to produce slop, they can also help you make great software↗

My YC batch wrapped up yesterday & I wanted to share a few of the companies I was close with and think you should check out! @hoplite_sh - cloud agents with a beautiful design - their onboarding flow is incredible and gets you up and running super quickly @try_glen - organizati…↗

We're not using enough inference We're going to look back on the amount of inference we used in 2026 as laughably small In order to properly read this article, you have to assume two things are true: 1. The cost of inference is going to 0 2. Agents will be good enough to auto…↗

i'm at a weird point with agentic development where if i go slowly, use agents mainly as context gathering, i love shipping and am proud of the product the moment i try to do more with agents though things become a mess. theoretically loops solve this but i am doubtful↗

i think i've come around to AGENTS.md being one of the most important files your project can have and yet none of the major harnesses treat it like that↗

figuring that out with Fable now, i first started by just brain dumping everything that i want to have agents running for i think this might turn into an Executor feature of 'Agents' where you store a: - name - goal - allowed toolset and then it just handles dispatching an API…↗

launching integrations.sh today! it's an open source catalog of every products MCP / API / CLI / GraphQL server and how to authenticate to them deep links to generate api keys, 1 click copy spec urls, it's still early but i've been loving having it↗

Executor is joining the YC S26 batch! We're building an open source MCP gateway to connect any agent to any service Your team is constantly spinning up new agents, trying out new tools, wrangling multiple accounts. You need one place to configure everything once, and use them a…↗

executor now has a desktop app! add whatever MCPs / OpenAPIs / GraphQL servers you want once and then every agent can use them converts them all into code mode under the hood, so you can have thousands of tools and no context bloat everything stays 100% local on your device↗

@trq212 tangentially related but does the web fetch tool in claude code just return the full html to the model? would be maybe interesting instead to let it write queries against the html page for better parsing of large docs↗

YC's RFS is actually thinking too small, it's not just dynamic software interfaces - it's dynamic software This demo is built on CF's Dynamic Worker loaders and you can have persistent storage, API routes, and use any frontend framework There's so much potential here↗

love seeing executor & the execution layer post in this video! i'll have a lot more to share on executor this week, it's a bash replacement for your agents and feels like the future of how we give our agents access to tools - try it out! executor.sh↗

there's an interesting new trend with how interact with OSS i'll clone the repos & run them locally, whenever its missing a feature i'll just prompt it to add it did this with t3 code this weekend to add ssh support, cmd + k, fast mode now i have a set of patches i like and wa…↗

The Execution Layer LLMs are in desperate need of an execution layer made for them to run tool calls in. A year ago LLMs were making direct calls to tools, we found that it flooded their context with irrelevant information to them and found incredibly poor performance. Then we…↗

New Cursor Rule: When provided with a git repo url, clone it into /tmp so it can be explored & understood↗
