Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up. Use when implementing a feature or fixing a bug where correctness matters and a test can pin the behavior. Says "TDD", "test first", "red green refactor", "write the test first".

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

# tdd

The agent codes better with a tight feedback loop than with a long
specification. A failing test is the tightest loop there is: it states the
target, and the target either goes green or it does not.

## The loop

1. **Red.** Write one failing test that states the next slice of behavior.
   Run it. Confirm it fails for the right reason - a test that passes before
   you write the code is testing nothing. If it errors instead of failing on
   the assertion, fix the test setup first.
2. **Green.** Write the least code that makes the test pass. Not the general
   solution, not the abstraction - the minimal move. Run the test. Green.
3. **Refactor.** Now clean up with the test as a net: remove duplication,
   name things, simplify. Re-run after every edit. Behavior is frozen; only
   the shape changes.
4. Repeat for the next slice. Small slices. The rate of feedback is the
   speed limit - never take on a step too big to hold a single test.

## What makes a test worth writing

- **Tests behavior, not implementation.** Assert on the observable result,
  not on which private method got called. A test that breaks on every
  refactor is a liability.

How to install

The exact contents, by fingerprint

mdr add rohitg00/pro-workflow/tdd@sha256:6f872ab005db3e9d

The line at the top of this page pins the label git:20260718.7f7209d, 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.
