Agents decide “whose role does the work”. The prompt library decides “which reusable text to insert into the input box”. Maintain both in Settings, and call them from the input box with `#` and `!`. ## Agents Open **Settings → Agents**. You can: * Create an agent: name + prompt (role, tone, process, tool preferences) * Edit or delete * Import / export JSON * Type `#` in the input box to select one The prompt is sent to the model as a system instruction when the conversation starts. Agents list ### Import conflicts When you import an agent that already exists, pick a strategy: | Strategy | Result | | --------- | -------------------------------- | | Skip | Keep the existing one | | Overwrite | Replace it with the file version | | Copy | Generate a new ID and keep both | ### Switch in chat Type `#` to open completion. After you select one, the current session uses that agent. You can clear the selection to return to default behavior. ## Prompt library Open **Settings → Prompt library**. Prompts are reusable templates, useful for: * A code-review checklist * A commit-message outline * A fixed opening such as “propose a plan first, then change the code” After you create one, type `!` in the input box to insert it. Insertion is text, so you can still edit it before send.
