Rewrite how the agent sees any built-in tool
Each built-in tool now has a description you can rewrite in Inventory. The agent reads your words from its next turn, and reset brings the original back.
Every built-in tool, such as read, edit or bash, comes with a short description the agent reads to decide when to use it. You can now rewrite it in Inventory, so the agent picks a tool the way you prefer. The change reaches every chat at its next turn, never in the middle of one, and reset restores the original.
Nothing changes unless you write something: with the originals in place, what the agent reads is byte for byte the same as before, so it costs no extra tokens. Your text is kept with your other Inventory choices, and a save that fails leaves both your inventory and the agent's tools as they were.
