module-regression SKILL.md skillA

module-regression from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add affaan-m/ecc/module-regression@git:20261011.4ce5ae0

Pins git:20261011.4ce5ae0 in mdr.lock. Pin the fingerprint instead.

Govern cross-module regression in large repositories with a REGRESSION.md ledger that records each module's downstream consumers and executable acceptance command. After a change, run the changed module and every affected downstream command, and use observed exit codes as regression evidence under the project's delivery policy. Use for module regression, regression ledgers, impact audits, downstream verification, and changes where modifying A may break B.

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

# Module Regression Ledger

## When to Activate

- The repository has at least three interdependent modules, or a previous change to A has broken B.
- A change modifies a module's externally observable behavior and must prove both that module and downstream consumers still work.
- The project already has executable tests or reconciliation commands that should be organized by dependency.

## Anti-Patterns

- Creating a regression ledger for a small repository with no cross-module dependencies.
- Guessing dependencies manually or treating one scan as permanent truth.
- Replacing executable acceptance-command exit codes with model review.

## Related Skills

- `test-collaboration`: TEST-IDs, test assets, and defect-regression evidence.
- `ai-regression-testing`: executable regression tests derived from important defects.
- `contract-first`: cross-service or cross-client contract verification.
- `change-impact`: pre- and post-implementation blast-radius analysis.

How to install

The exact contents, by fingerprint
mdr add affaan-m/ecc/module-regression@sha256:5c3db104f8e4aec8

The line at the top of this page pins the label git:20261011.4ce5ae0, 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.
