Deep knowledge for Outside-In TDD - double-loop architecture, ATDD integration, port-to-port testing, walking skeletons, and test doubles policy.
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
# Outside-In TDD Methodology ## LANGUAGE CONVENTION FRAME (read FIRST — overrides all examples below) **Code examples in this skill use Python syntax for illustration only.** They are NOT prescriptive about target language. nWave is language-agnostic per the "genericity and agnosticism" mandate (2026-05-24). **Before applying TDD cycle**, detect the target project's language from manifest files: `package.json` → TypeScript/JS (jest/vitest); `Cargo.toml` → Rust (cargo test/proptest); `go.mod` → Go (testing/ginkgo); `pyproject.toml`/`setup.py`/`Pipfile` → Python (pytest/hypothesis); `pom.xml`/`build.gradle` → Java/Kotlin (JUnit5/jqwik); `*.csproj`/`*.fsproj` → C#/F# (xUnit/FsCheck); `Gemfile` → Ruby (RSpec); `Package.swift` → Swift (XCTest/swift-testing). **When the target language is NOT Python**: adapt EVERY code example — replace Python imports, type hints, class/function syntax, test-framework specifics with target equivalents. Project conventions ALWAYS WIN over skill examples. …

How to install
mdr add nwave-ai/nwave/nw-tdd-methodology@sha256:3a1dc0eaf81c3ddbThe line at the top of this page pins the label git:20260623.2e5049d, 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.
