This directory holds locally-developed policies for testing and iteration during development. Policies here are not included in production builds unless explicitly listed in gateway/build.yaml.

1. Create a directory under dev-policies/ for your policy (e.g. dev-policies/my-policy/). It must contain at minimum:

   • go.mod – module definition (depend on the SDK: github.com/wso2/api-platform/sdk)
   • A .go file implementing policy.Policy
   • policy-definition.yaml – the policy's parameter schema

2. If you are working on a new policy, copy the policy-definition.yaml to the default policies directory:

   cp dev-policies/my-policy/policy-definition.yaml \
      gateway-controller/default-policies/my-policy.yaml

   Important: The file must be renamed to match your policy name (e.g., my-policy.yaml) so the gateway controller can load the policy definition.

3. Register it in gateway/build.yaml using a filePath entry:

   policies:
     - name: my-policy
       filePath: ./dev-policies/my-policy

4. Build locally:

   cd gateway/gateway-runtime
   make build

Remove your filePath entry from gateway/build.yaml and the copied policy definition from gateway-controller/default-policies/ so that CI and production builds are not affected. The policy source under dev-policies/ can stay — it is ignored by the builder unless referenced in the manifest.

count-letters/ is a sample dev policy that counts character occurrences in response bodies. Use it as a reference for structure and conventions.
