Use when implementing any feature or fix outside code-forge workflow — enforces Red-Green-Refactor cycle with mandatory test-first discipline. Supports three modes: (1) Standalone — ad-hoc TDD for quick changes, (2) Auto-Analysis — runs the full spec-forge:test-cases analysis pipeline (project profile, four-layer deep scan, multi-dimensional coverage) then implements all cases via TDD, (3) Driven — reads a test-cases.md document and implements each case via TDD.
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
# Code Forge — TDD ## ⚡ Execution Entry Point @../shared/execution-entrypoint.md **For this skill:** start at **Step 0 (Determine Mode)**. If you catch yourself about to say "falling back to manual TDD", STOP and go to the indicated step. --- Test-Driven Development enforcement for any code change, with built-in code analysis. ## When to Use - Writing code outside of code-forge:impl workflow (ad-hoc changes, quick fixes) - Adding tests to existing code that lacks coverage - Implementing test cases from a spec-forge:test-cases document - Any new feature, bug fix, or behavior change that needs test discipline **Note:** code-forge:impl already enforces TDD internally. This skill is for work outside that workflow. ## Iron Law **NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST.** No exceptions. Not for "simple" changes. Not for "obvious" fixes. Not when under time pressure. ## Design Discipline (Mandatory, Applies to All Modes) …

How to install
mdr add tercel/code-forge/tdd@sha256:439d938e6b32b49aThe line at the top of this page pins the label git:20260422.d0e053f, 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.
