Skillforge

The company brain for AI agents. Built for Y Combinator Summer 2026 against Tom Blomfield's "Company Brain" RFS.

Live demo: https://skforge.dev/demo

What it does

Skillforge connects to a company's Slack, Notion, Drive, GitHub, Intercom, and Linear; extracts structured facts with provenance; and synthesizes them into executable skills in Claude's Agent Skills format.

The output is a folder of versioned SKILL.md files an AI agent can pick up and run — turning generic agents into ones that know your refund matrix, your discount ladder, your incident runbook.
