Use when comparing prompt changes against a fixed evaluation set: record actual model settings, required checks, missing results, judge limitations and case-level regression evidence.
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
# AI Prompt Regression Testing ## When to Use - Compare a prompt change with an observed baseline on a fixed evaluation set. - Detect schema, factuality, refusal, tool-selection or task-completion regressions. - Record a reviewable decision when results are noisy, missing or contradictory. ## Workflow 1. Define the task, representative cases and forbidden outcomes. Use synthetic or approved/redacted data; freeze case IDs and the dataset revision before runs. 2. Record baseline/candidate prompt digests, exact available model/version, inference settings, tool versions and evaluation environment. Do not hardcode old model-family options or silently change models between comparisons. 3. Predeclare checks and acceptance rules. Use deterministic schema/field checks for structured output, behavioral checks for tools and a clear human/rubric standard for open text. Similarity does not prove factual or code correctness. 4. Run matched baseline/candidate cases under the same permissions and budget. Record latency/cost and repeated runs when variability matters. A timeout, missing output or judge error is incomplete, not a pass or a zero-cost result. …

How to install
mdr add francostino/opencode-skills-collection/ai-prompt-regression-testing@sha256:178bf2b9ac6ca913The line at the top of this page pins the label git:20261015.fac8b7e, 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.
