test-development skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
test-development is agent-read markdown (skill) from deathemperor/infinitus: Test development. Use when adding or changing runtime Vitest coverage or Tstyche contracts for behavior, inference, assignability, or displayed public types..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
Select every applicable branch before editing: - **Runtime behavior:** Read [runtime.md](runtime.md). - **Type contracts:** Read [types.md](types.md). Some changes may require both branches. The task is complete when every changed runtime behavior and type contract has focused coverage, targeted tests pass, and applicable root checks pass or are reported as not runnable.
Read the whole file at its exact version.
How to install
mdr add deathemperor/infinitus/test-development@git:20260918.e3c85eamdr add deathemperor/infinitus/test-development@sha256:ded4ade9f625fbccPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
