Autonomous Documentation Generator

Developer Tooling

Autonomous Documentation Generator

Analyzes code structure, function signatures, and runtime behavior to generate README files, API docs, and inline comments.

The problem

Documentation falls out of sync with code because engineers update source faster than they update prose docs.

  • New hires ping the team in Slack because the README describes last quarter's API.
  • Nobody wants to be the one who blocks a PR over missing docs.
  • The docs site says one thing; the code does another, and no one notices until support does.

What NEO built

NEO built an agent that parses repos with AST-aware (tree-sitter) analysis, generates README and API docs from inferred signatures, and only regenerates pages affected by a diff, opening PRs directly in CI.

The result

4 languages, diff-aware

Keeps README, API reference, and architecture docs automatically synchronized with the current codebase, with zero manual upkeep.
