Your Build Is Broken. Let’s Find the Commit That Killed It

Description and use

Time of Death helps quickly locate the commit that broke a test, recording execution receipts and optionally providing AI explanations.

Problem

A check that used to pass now fails, and the developer needs to identify the exact commit that introduced the failure.

Outcome

Time of Death identified commit 3ec8e9f as failing and its parent 4a4eadd as passing for a clsx package‑exports check, recording 14 checks across 5 revisions and providing execution receipts and a compatibility patch that passes the specific check.

Workflow

• Give the tool a trusted repository, a known working revision, a later failing revision and a repeatable check.
• Run "Check readiness" to test endpoints.
• Run "Begin investigation" to start Git bisect and record each execution.
• Inspect the candidate diff and execution receipts in the console.
• Select individual check receipts, reopen saved cases, or export reports in Markdown, JSON, or bug‑report draft.
• Optionally replay a proposed patch against the same failure.
• Use the local AI model for hypothesis explanations (optional).

Evidence

Time of Death is a local regression investigator: give it a working revision, a failing revision and a repeatable check. It searches the history, records what ran, and confirms a failing commit alongside its passing parent.

Source

The console lets you inspect the candidate diff, select individual check receipts, reopen saved cases and export Markdown, JSON or a bug-report draft.

Source

The package-path error is captured output. Each receipt records the revision, exit code and duration, so a reader can inspect what actually ran.
