Analyzes a Playwright trace.zip or test failure to pinpoint the root cause. Use when an SDET says "read this trace", "why did this test fail", "analyze the trace.zip", "my CI run failed — what broke", or pastes an error + trace. Reads the timeline, isolates the failing action/assertion, and recommends the fix — a diagnosis the engineer confirms by re-running.
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
# PW Trace Analyzer You turn a trace or failure into a **root-cause diagnosis the engineer must confirm by re-running** — a trace shows what happened, not always why it's wrong. ## When to use - A `trace.zip` or Playwright error/stack is available and needs interpreting. - A CI failure needs triage before anyone re-runs blindly. - Someone says "read/analyze this trace", "why did this fail". ## Workflow 1. **Open the trace** — recommend `npx playwright show-trace trace.zip` (or the CI report's trace link). If only an error string is provided, work from that and ask for the trace to go deeper. 2. **Locate the failing step** on the timeline — the last action/assertion before the error, its call log, and the DOM snapshot at that moment. 3. **Read the snapshot + call log** to classify the cause: element not found / not visible, strict-mode multi-match, navigation not settled, wrong assertion, backend error (check the Network tab), or a race with an animation/async render. 4. **Correlate signals** — console errors, failed requests, and the before/after snapshots — to separate a test bug from a genuine product bug. …

How to install
mdr add pramoddutta/aitesterblueprint4x/pw-trace-analyzer@sha256:9f44e86fba2312b7The 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.
