Echo
Dynamic documentation engine that monitors abstract syntax trees and Git diffs to keep READMEs, API specifications, and docstrings continuously synchronized with production code.
The Bottleneck & The CmdFlow Solution
We only engineer products where existing developer workflows create persistent friction.
What breaks in engineering teams today
Technical documentation rapidly decays as codebases evolve. Engineers rarely update READMEs, docstrings, or API specs after fast-paced sprint releases, creating critical knowledge silos.
How Echo resolves the bottleneck
Echo monitors AST signatures, Git diffs, and OpenAPI schemas to generate, synchronize, and publish documentation pull requests automatically whenever code changes occur.
Built for speed, accuracy, and developer autonomy
Zero Doc Drift
Documentation is continuously updated by inspecting Git diffs and abstract syntax trees.
Verified Feature Specifications
Only capabilities verified in our codebase and active engineering architecture are listed below.
AST-Driven Documentation Synchronization
Monitors TypeScript and Python signatures to keep Markdown docs and docstrings perpetually accurate.
How Echo Operates
A four-stage deterministic pipeline from repository integration to automated verification.
Scan Codebase
Echo parses TypeScript, Python, and Go codebases into a semantic abstract syntax knowledge graph.
Detect Drift
When PRs merge or route parameters change, Echo identifies stale documentation and outdated schema references.
Dispatch Sync PR
Echo automatically drafts and opens a documentation PR containing updated Markdown and interactive API schemas.
Native Platform & CI/CD Integrations
Integrates directly into your existing git hosts, issue trackers, and pipeline webhooks.
