ripwire-write-tests from redhat-et/ripwire is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Write tests for EXISTING code that has none — 'this is untested, add coverage', 'add a safety net first'; also verify a new test reaches its intended code. Finds what no test reaches: --seams ranks untested cross-module edges, --callers gives the outside contract. Diff test selection → change-check. For one target one --seams or --callers pass suffices.
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
# Writing tests with ripwire > Routing: > • Vetting a diff you already wrote (does it have test cover) → **ripwire-change-check**. > • Judging whether your OWN code got better/worse → **ripwire-quality-bar**. > • Don't know which symbol is even the bug → **ripwire-find-bug**. > • Not sure which skill? → **ripwire-router**. `<dir>` = repo root. This skill answers "what should I write a test for, and what does it need to cover" — not "is my diff safe" (that's change-check). ## Find the gap 1. **Untested integration seams** — `ripwire <dir> --seams --legend=compact` → `<seams>` lists cross-module call edges no test reaches. These are the highest-value targets: a bug here crosses a boundary silently, and one test per seam buys the most coverage per line written. Scope with `<dir>` = a subsystem to focus the seam list. 2. **The `tested=1` coverage lens** — `ripwire <dir> --metrics --legend=compact --top-k=50` (or `--for="<area>"`, which carries the same lens inline) → `tested="1"` means an indexed test-path symbol transitively reaches this production symbol. On these explicit metric surfaces the attribute is omitted when no indexed test …

How to install
mdr add redhat-et/ripwire/ripwire-write-tests@sha256:998b73023fb2508aThe line at the top of this page pins the label git:20260913.30a5a3c, 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.
