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. …
