I Scraped All 234 YC Summer 2026 Startups and Found 31 That Are Just a SKILL.md

Description and use

31 YC Summer 2026 startups were converted into open‑source SKILL.md files, enabling agents to perform their tasks without proprietary infrastructure.

Problem

Many YC startups claim to be AI agents but are actually repeatable workflows that can be expressed as SKILL.md files.

Outcome

31 YC startups were converted into reusable, open‑source SKILL.md files, enabling agents to perform their core tasks without proprietary infrastructure.

Workflow

• Scrape YC API for 234 startups
• Classify each startup into SKILL, PARTIAL, or NO based on core value
• Identify 31 SKILL startups with repeatable procedures
• Create a SKILL.md for each, including Procedure, Pitfalls, Verification
• Publish each skill in a folder structure compatible with Claude, Cursor, OpenCode, Hermes
• Copy skill folder into harness and invoke via agent prompt

Evidence

I scraped all 234 companies in the Summer 2026 batch, read every one-liner, and asked one question.

Source

31, ~13%: the core is a documented procedure an agent executes.

Source

Each one is now a self‑contained, open‑source SKILL.md with a Procedure, the Pitfalls, and a Verification step.
