CI/CD bots and automated code review

One binary in a container, fast startup, no pip install step that breaks on a Tuesday.

The problem

Review bots summarise diffs, flag risky patterns, and suggest tests. Container images that start with pip install -r requirements.txt are fragile CI citizens: a yanked package or upstream metadata change turns green builds red.

Why Ecko

Copy binary, run
Multi-stage Docker: copy ecko and your .ecko sources. Startup is milliseconds, not minutes of dependency resolution.
Pattern matching
Real match on AST-shaped data for deterministic checks; use ai only where semantics matter.
py() escape hatch
Call an existing Python library when you must - without making Python the runtime for everything else.

In practice

Dockerfile
FROM debian:bookworm-slim
COPY ecko /usr/local/bin/ecko
COPY review.ecko /app/review.ecko
ENTRYPOINT ["ecko", "/app/review.ecko"]
