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 — ave

For this repo, TDD means: fixtures first, then rule, then record validation.

## Loop for a new rule

1. Write the positive fixture (the malicious file)
2. Write the negative fixture (the benign lookalike)
3. Write a test asserting the rule fires on positive, not on negative → FAIL
4. Write the rule → test PASSES
5. Write the AVE record JSON
6. python scripts/validate_records.py → record valid
7. pytest tests/ -x -q → full suite green

## What/Why/How on validation functions

```python
# What: returns True if every record in records/ validates against the schema
# Why:  one malformed record breaks every scanner that loads the record set
# How:  loads each JSON, runs jsonschema.validate, collects all errors
def all_records_valid() -> tuple[bool, list[str]]:
    ...
```

## The negative fixture rule

Every rule needs a negative fixture that looks SIMILAR to the positive
but is benign. A rule with only a positive fixture is a false-positive
waiting to happen. Test that the rule does NOT fire on the negative.

How to install

The exact contents, by fingerprint
mdr add aveproject/ave/tdd@sha256:55ae3ed36749b708

The line at the top of this page pins the label git:20260618.9c6c22c, 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.
