Use when the user explicitly requests strict or test-first TDD, or when the current conversation already contains an explicit `TDD Route: strict` decision from another Aegis workflow.
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
# Execute → False-positive entry on a native-direct-skill host? → **Exit immediately unless the user explicitly asked for TDD or the conversation already contains `TDD Route: strict`.** In `off` mode, do not start RED / GREEN / REFACTOR from generic bugfix, contract, shared-module, or risky-code wording alone. Hand control back to `using-aegis`, `systematic-debugging`, `writing-plans`, or the fast path with verification. → Implementing a feature or bugfix under TDD Route `strict`? → **No production code without a failing test first.** Gate: medium/high complexity? → route to brainstorming or writing-plans first. Mode: default `off` disables automatic TDD, not completion verification; `auto` chooses strict/light/skipped by risk. Change Necessity: before strict RED/GREEN enters production edits, confirm the slice really needs a code change. Cycle: RED (write test → watch it fail) → GREEN (minimal code → watch it pass) → REFACTOR (clean up → keep green) Regression: shared module → related tests. contract change → producer + consumer. core logic → old + new tests. Ripple signal hit → cover producer+consumer or real user path before claiming green. …

How to install
mdr add ganyuanran/aegis/test-driven-development@sha256:de850e1b4e3911eaThe line at the top of this page pins the label git:20261010.8d5b88e, 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.
