Second-pass regression trace after a bug fix, to catch what the fix itself broke. Use after completing a fix from your debug workflow (trace-based debugging, systematic debugging) and before marking the session done, especially when the fix touched shared code, changed control flow, modified model relationships, altered sync or persistence behavior, or moved work between threads or actors. Maps the blast radius, checks adjacent user flows, and runs impacted tests. Triggers: 'verify the fix…
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
# Post-Fix Regression Trace After you fix a bug, you've changed the system. That change might fix the original problem and quietly break something else: a calculation that stops recomputing, a field that is no longer persisted, a query that now includes soft-deleted records, a new main-thread bottleneck. The first trace found the disease; this trace checks whether the surgery nicked an artery. ## When This Runs This skill activates after a fix is applied: after the fix gate of your debug workflow, after the fix phase of systematic debugging, or after any bug-fix commit. It runs before the debug session is considered complete. A fix that hasn't been traced for side effects is not yet done. ### Precondition: is the debug session actually done? Check whether the user is still providing diagnostic input. If they are pasting logs, sharing crash reports, describing new symptoms, or asking questions about the bug, the session is still active and your fix is a hypothesis. Don't run this yet. Wait for them to finish, or ask: "Are there more symptoms to look at before I verify this fix?" …

How to install
mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/post-fix-trace@sha256:a1194ed4fe3ee19bThe line at the top of this page pins the label git:20261108.5e6d7c1, 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.
