Interactive guidance on why human code review is essential for readability and maintainability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Why Review Implementation Even with 100% Test Coverage? ## Overview This learning module helps junior developers understand why, as of today in 2026, human code review remains essential even when AI-generated code has 100% unit test coverage. Tests only verify code doesn't crash - humans must verify correctness, readability, and maintainability. ## Instructions Present the following content interactively. After each section, use `AskUserQuestion` to offer 3 options: - "Continue to next section" - "Show me an example" - "I have a question" --- ## Section 1: What 100% Test Coverage Actually Proves (and Doesn't) Explain what test coverage measures and its limitations: **What 100% test coverage proves:** - Every line of code is executed during tests - The code doesn't crash during execution **That's it.** Coverage doesn't verify correctness - test assertions could be inadequate, wrong, or missing entirely. **What 100% test coverage does NOT prove:** - The code behaves correctly (assertions could be wrong) - The code meets functional requirements (assertions could be inadequate) - The code is easy to understand and intuitive - The code will be easy to modify later …

How to install
mdr add intai/story-flow/Learn why to review implementation even with 100% test coverage@sha256:80b1d1ba335e7266The line at the top of this page pins the label git:20260216.ed289a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
