Use this skill when you need to discover boundary, rare, limit, ordering, or combination scenarios from product and test evidence; triggers include edge case discovery.
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
# Edge Case Discovery Discover boundary candidates across data domains, state models, time rules, resource limits, platform differences, and existing evidence. Produce `EC-##`. This is not a full requirement-quality review, full test-case authoring, threshold invention, or test execution. ## When to Use - Use it to systematically consider value, length, null/type, time, state, capacity, concurrency, platform, and combination boundaries. - Use it to find high-risk boundaries outside the happy path from defects, failures, or design constraints. - Use it to prioritize boundary candidates and turn them into verifiable follow-up test intent. Do not use it only to analyze requirement gaps, write a complete test case suite, review existing cases, or execute boundary tests. ## Output Format Options - Use Markdown by default; when a table, CSV, or JSON is requested, preserve the same evidence, status, impact, owner, and validation fields. - Do not present a structured format or static inventory as execution, pass, approval, or release evidence. ## How to Use 1. Read this Skill's primary prompt and provide the objective, scope, material, environment, and available evidence. …

How to install
mdr add naodeng/awesome-qa-skills/edge-case-discovery@sha256:b623936f76faa31cThe line at the top of this page pins the label v1.0.0, 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.
