Multi-repo orgs need a shared brain for AI agents

The claim

Every engineering organization running AI coding agents at desk-rate will need a shared, file-based playbook the agent reads first — the way every developer team needed shared lint rules a decade ago — and the layer that wins is the one that survives a session restart, not the one with the slickest UI.

The evidence

GitHub Copilot reached 1.3M paid seats by late 2023 (GitHub disclosure, Nov 2023). Cursor passed $100M ARR in 2024 on a per-developer plan (Cursor public memo). Anthropic’s Claude API was issuing 4B+ tokens per day by mid-2025 (Anthropic earnings note). None of those tools persist project context across a session boundary — every fresh session re-learns the project from scratch. The unmet job is durable, agent-readable project memory: what the project is, what is done, who to delegate the next move to.

In a 31-repo workspace, three plain text files (CLAUDE.md, MILESTONES.md, AGENTS.xml) are already standing in for what a code-search index does for humans. That is the wedge.

The comparable

ESLint shipped in 2013 to a market that already had JSHint and JSLint; it won on shareable config and per-project overrides — a single workflow file the whole team agreed on. By 2020 it was a dependency in 30M+ npm projects (npm registry stats). PETROVA is ESLint for AI-agent context: one paste-in bootstrap, three files the whole repo agrees on, zero runtime.

What we ask for

A pre-seed conversation framed around “agent context as a configuration category,” not “yet another AI copilot.” We are not pitching a model, an IDE, or a marketplace. We are pitching the thin, durable layer that every AI-agent workflow will end up needing once the second engineer joins the project.

  title Configuration categories that started as paste-in files
  2013 : ESLint : single .eslintrc file shared per repo
  2015 : Prettier : single .prettierrc file shared per repo
  2018 : Renovate : single renovate.json file shared per repo
  2023 : AI coding agents : 1.3M Copilot seats, 4B tokens per day
  2026 : Agent context as config : the next paste-in file category
