Simulate a session and analyze diffs

This skill covers running a single simulation and interpreting the results. For the simulate command's full option reference see the meticulous-cli-simulate skill.

Before starting, run the meticulous-cli-update skill to ensure the Meticulous CLI is up to date — unless it has already run earlier in this conversation, in which case skip it.

Prerequisites

A sessionId to replay

An appUrl (local dev server, or leave blank to use the original recorded URL)

Optionally: a baseReplayId — the ID of a prior replay to diff screenshots against. Without this, screenshots are stored but not compared.

If you don't have a baseReplayId, you can find one from a downloaded test run:

meticulous download test-run
# Then inspect ~/.meticulous/test-runs/<testRunId>/coverage.json
# or check the testCases[].replayId fields
