Gateway profiles

Per-computer network rules. Control what agents can reach by host, path, method, and rate limit.

gateway.rule
host    api.github.com
path    /v1/*
action  allow
methods GET, POST
rate    100 req/min
Content filters

Scan response bodies for leaked answers. If an agent fetches a solution, the gateway blocks it.

Credential injection

Agents get access, never keys. Secrets are injected by the proxy and stay out of trajectories.

inject.yaml
match   api.openai.com
header  Authorization
value   {{ secrets.OPENAI_KEY }}
