Where is the user right now?

When the user says "fix this page", "tweak this heading", or "the slide I'm looking at", they almost never name the slide id, page number, or element, they mean wherever they are in the dev viewer. Before asking "which slide?" or "which element?", check the file the dev server writes on every navigation and inspector pick.

Re-read on every deictic turn, never reuse a prior read

current.json is a live cursor, not a fact about the conversation. The user moves between slides, pages, and elements freely between your turns, including while you were doing other work. Read the file fresh at the start of every new turn that uses a deictic reference, even if:

• you already read it earlier in this same conversation,
• you just finished editing the slide it pointed to,
• the user's new message sounds like a continuation ("now make it bigger", "also fix this one", "keep going").

A "continue editing" follow-up is exactly the case where the user has likely just navigated to a different slide or picked a different element. Trusting your last read here will silently edit the wrong file. Re-read, compare slideId / pageIndex / selection against what you used last time, and act on the new values.

How to read it

node_modules/.open-slide/current.json

Path is relative to the project root (the user's cwd, the directory that contains slides/ and package.json). Use the Read tool. The file is JSON.
