The second page is where lists break

A list that renders its first page proves the first request works. The second page is where the offset is off by one, the cursor is reused, the same rows come back, or the append replaces what was there. The last page is where the "Next" button still fires a request for rows that do not exist.

Reticle can check all of that in the running app, against the requests the page really made. Not installed? RETICLE_INSTALL_SOURCE=npx_skill npx @reticlehq/server@latest init, then the install-and-verify skill.

Confirm the session can observe

reticle_session({ action: "list" })

A hidden or throttled tab can accept a click and render nothing, and an infinite scroll that loads on an intersection observer may never fire at all. If the session is not healthy, get a context that is, for example a leased tab (reticle_run({ tool: "reticle_lease", args: { action: "acquire", url } })). Otherwise report the run as blocked, not passed.

1. Record the first page

Write down what is on screen before you touch anything, or you have nothing to compare the next page against:
