<Badge color="blue">AI Agent</Badge>

A lightweight allow/deny send-policy with an optional default-deny posture.

This is the config-driven default referenced by `send_policy` blocks in
`gateway.yaml` and the `Bot(..., send_policy=...)` Python surface. It is
intentionally minimal (no heavy dependencies) and lives in core so the
built-in `send_message` path is always interceptable.

Matching is exact against the symbolic target token (e.g. `"origin"`,
`"slack:#ops"`, or a friendly alias). With `default="deny"` only listed
targets are permitted; with `default="allow"` all targets are permitted
except those in `deny`.

Example::

```python theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
# default-deny: only the conversation origin and an ops alias allowed
SendPolicy(default="deny", allow=["origin", "ops-alerts"])
# default-allow: everything permitted except an exec channel
SendPolicy(default="allow", deny=["slack:#exec"])
```
