* The agent's tools (agent phase P4): a whitelist instead of file access.
|
||
*
|
||
* Every tool has a JSON schema (validated by the gateway before a handler runs), a right,
|
||
* and a handler. Read tools look at the site, stage tools add operations to the run's
|
||
* change set. No tool writes outside content/ai-agent/staging/, none takes a file path,
|
||
* none runs code. Results are JSON text; errors are {error, hint} so the model can correct
|
||
* itself.
|
||
*
|
||
* Web research, stock images and image generation are tools too; uploads go through the
|
||
* upload endpoint.
