Use service inline upstreams and service-backed routes unless you are intentionally documenting APISIX-compatible behavior. -- Gateway/httpbin traffic checks are optional for `a7`; the default CI focuses on CLI-driven control-plane resource CRUD and structured `get/list/dump` assertions. +Changes to skill content (new plugins, recipes, wording fixes) go to +[api7/agent-skills](https://github.com/api7/agent-skills).

Only accept `X-Forwarded-For` from known proxy IPs. - -### Custom 404 response (hide endpoint existence) - -```json -{ - "plugins": { - "ip-restriction": { - "whitelist": ["10.0.0.0/8"], - "response_code": 404, - "message": "Not found" - } - } -} -``` - -> Note: You cannot actually use both whitelist and blacklist.
