AI should not bypass the browser's local file-selection permission.
Let AI hand the job to the right tool without crossing your safety boundaries.
FileNest publishes each web tool's inputs, outputs, access and quota, processing location, human confirmation, success definition and recovery. AI can use that information to choose the right entry point and assist with the UI, but there is currently no remote execution API that bypasses browser file selection, account checks or confirmation.
Declare what can be done and what must never happen silently.
Contract last updated 2026-08-30. Current live tool behavior always outranks stale cached descriptions.
Quota, privacy mode, output preview and download decisions remain governed by the live UI.
No automatic deletion or source-file overwrite, and a button click is never treated as task success.
Every entry point has an explicit success definition and recovery path.

Prove that AI handoffs create successful tasks before opening deeper automation.
The current goal is to make existing web tools easier for AI systems to understand, recommend and navigate, rather than prematurely opening an expensive, abuse-prone remote file-processing interface.
