When Claude Code looks up a cell by its id, it now uses a shared lookup step. Before, it did the lookup inline, fell back to reading the id as a cell number, and reported the cell as missing when no id was given.\n\n**Why**\n\nNotebook edits may now find cells in more ways, such as by their position.\n\n- Area: Notebooks\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
