Testing & Quality
View on GitHub

Open and triage recorded Canary sessions in the local viewer. Use when the user wants to look at, replay, compare, or triage a recorded session — or asks what happened in a run, to open the report, or to see the trace/video/screenshots. Trigger phrases — "open the canary viewer", "show me the last session", "what failed in that run", "review the recording", "open the report".

Canary review (triage)

Open recorded sessions in the local viewer and summarize what happened. Sessions live in ~/.canary/sessions/<id>/ — each has results.json, report.html, and trace / video / HAR / console / screenshots.

When to use

  • Browsing or replaying recorded sessions.
  • Triaging a run: which steps passed/failed, console errors, network failures.
  • Opening the report or the trace for a specific session.

Examples

Example 1: open the viewer

User says: "open the canary viewer" or "let me see my sessions" Run npx @usecanary/ui (a local server, like npx playwright show-trace) in the background and give the URL. Pass --dir <path> for a non-default folder.

Example 2: triage the last run

User says: "what failed in the last session?" or "summarize the latest run" Read the newest ~/.canary/sessions/*/results.json, summarize steps (pass/fail, durations, console/network issues) with the report.html path, then open the viewer.

Workflow

  1. Browse: npx @usecanary/ui (--dir <path> for a non-default sessions folder). List sessions without the UI via npx @usecanary/cli session list; check what's running with npx @usecanary/cli status [--session <id>].
  2. Summarize: read the session's results.json (steps, summary, artifacts) and report pass/fail with counts; cite the report.html path.
  3. Review is read-only — don't modify session files.
