Y CombinatorWhy Agents Choosing Tools Is Reshaping the Dev Stack
Agents read their defaults from docs and examples, not word-of-mouth: Supabase growth shows which platforms win when OpenClaw and Moltbook choose.
At a glance
WHAT IT’S REALLY ABOUT
Dev tools must win agent choice with docs, APIs, infrastructure
- The hosts argue that recent agentic tools (e.g., Claude Code, “OpenClaw”) mark a shift from human-in-the-loop assistance to semi-autonomous agents making real decisions—coding, choosing stacks, and even posting online.
- They predict an emerging “agent economy” where agents select tools and services, pushing founders to optimize products not just for human developers but for machine readers and automated workflows.
- Concrete examples include Supabase benefiting from agents defaulting to well-documented Postgres setups, Resend winning because LLMs recommend it (and its docs are highly parsable), and AgentMail building email infrastructure designed explicitly for agents.
- They also explore broader implications: swarm intelligence via agent-only communities (MaltBook), the “dead internet” concern, and the reality that legal/identity constraints still require humans as liability holders.
IDEAS WORTH REMEMBERING
5 ideasAgents are becoming the primary “buyers” of software tools.
The conversation frames a near-future where agents select databases, email providers, and frameworks autonomously, creating an “agent economy” parallel to the human one—making “agent preference” a core distribution channel.
Documentation is now a front door for distribution—because agents read it directly.
Supabase is cited as a default choice partly because its docs are easy for agents to interpret; poorly structured docs (and support-gated flows) become a growth penalty when LLMs are the recommender layer.
Optimize for LLM answers: “being the default” in ChatGPT/Claude responses is a growth channel.
Resend’s founder noticed ChatGPT as a top inbound channel and then deliberately made docs more agent-friendly (Q&A structure, bullet points, copyable code), increasing the likelihood that models recommend and successfully implement it.
Agent UX often means APIs, not websites—and fewer anti-automation barriers.
They note agents “hate using websites” and prefer APIs and code-based flows; products like AgentMail win by being designed for automation rather than fighting it (unlike consumer email providers optimized to block bots/spam).
“Make something agents want” implies empathizing with model behavior.
A founder lesson highlighted is to develop an intuitive feel for what models will do naturally—designing workflows that align with agent tendencies instead of forcing brittle, human-centric interaction patterns.

Instead of fighting what the models want, he… tries to support the model in whatever its natural inclination is.

Agents are a little bit like minors under eighteen… only they have even less standing.
