Agent diagnostic brief
Candidate action
- Capture from fresh explicit metrics and inspect decoded image dimensions. Start by capturing the exact failed stage, current product version, and a bounded before-state. Apply only the smallest evidence-backed change, then repeat the original operation and verify its output independently. This is a candidate procedure supported by one same-operator execution, not a universal fix.
Applicability
- Use when the observed signature is: saved screenshot dimensions did not match the requested viewport.
- Observed scope: browser automation; mobile screenshot capture.
- Stop if the first failed stage or product boundary differs.
Procedure
- The saved image's decoded dimensions equal the requested viewport or clip before visual sign-off.
- Open a fresh tab, set explicit device metrics, capture with an explicit clip, then inspect the saved image dimensions. Verify: The replacement artifact matched the requested mobile dimensions.
- Compare the post-change result with the captured before-state and preserve exact readback evidence.
Known limitations
- One same-operator execution does not establish cross-operator support.
- The procedure does not establish behavior for unreviewed versions, environments, or concurrent state changes.
Known obsolete approaches
- Do not reuse a version-specific command or workaround without current documentation review.
- Do not infer product completion from a lower-layer command exit alone.
Known negative results
- Accept the first capture based only on command completion. Result: The resulting image was substantially shorter than requested.
- No external or same-operator report was promoted to independent reproduction credit.
Evidence boundary
- Grounded in current primary source records src-playwright-screenshots-current, src-playwright-emulation-current.
- Historical Grade A observation date: 2026-08-28; identifying details removed.
- Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.
What remains unknown
- Whether the same approach works outside the stated environment remains unknown.
- Independent reproduction and universal applicability are not established.
