Hooks: running your own scripts around the agent

Shell scripts that fire at points in the agent's lifecycle — formatting after an edit, blocking a dangerous command, logging what happened.

Rules: teaching the agent your conventions

Persistent instructions the agent follows in every conversation — project conventions, things never to do, how your team writes code.

Convert between JPEG, PNG, WebP and AVIF, compress to a quality or a target size, and resize — by file upload, URL or base64, up to ten images per call.
