defect-hunting skillA
defect-hunting is agent-read markdown (skill) from vmobifystudio/app-dev-team: Use when reviewing code, auditing an app, writing a guard rule or test, or certifying any threshold/constant/formula. Finds the defects a diff review structurally cannot see — the second write path, the mis-calibrated constant, the rule that cannot fail. Triggers from code-reviewer, /app-audit, qa-engineer, verification-engineer, and any task that adds a lint rule, architecture test, or CI grep..
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
# Defect hunting Mined from a real remediation programme where twelve screen-by-screen review rounds found nothing new, and one round organised differently found dozens of live defects. Every one of these rules is paid for. **The sentence that generates all four:** > Verify the thing that has to be true, not the thing you changed. Filtering the list is not filtering the parser. Capping the severity is not capping its renderer. Matching the token is not matching the value. Mutating the file is not confirming the mutation landed. --- ## 1. Audit the data's entry points, not the screens A review organised by screen structurally cannot find these, because in every case **the audited surface was correct and the bug was in the second path to the same data** — usually another file, often another module: | What was reviewed | Where the defect actually was | |---|---| | Add-form validation | the **edit** path, which validated nothing | | the dashboard alert banner | the **detail screen** the banner opens — they disagreed | | the growth-target reader | the **writer**, which destroyed data | | the photo picker's success branch | its **cancel** branch, which wiped the existing photo | …

How to install
mdr add vmobifystudio/app-dev-team/defect-hunting@git:20260810.958b327mdr add vmobifystudio/app-dev-team/defect-hunting@sha256:4cf94d0107e1a8fePin 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.
