Agent Engineering Toolkit
Proof-carrying workflows for coding agents
AET binds test runs, changed files, artifacts, and agent claims to exact code. Its local stale-proof demo shows a real PASS becoming inapplicable after relevant source changes—without an LLM, API key, cloud account, product telemetry, or holistic trust score.
I built AET after repeatedly seeing coding-agent handoffs where “tests passed” was true at execution time but no longer applied after later edits. The v1.18.0 stale-proof demo makes that boundary reproducible: it runs a real unittest, records EXACT_MATCH, changes relevant source, then reports RELEVANT_FILES_CHANGED while preserving the historical PASS.
AET is local and evidence-first. It does not replace CI, infer complete coverage, score developer trust, or authorize a merge or release. I’d especially value feedback from maintainers who review agent-generated changes: which freshness errors create the most friction in real repositories?
