 - Use ${SERVER_MANAGEMENT_TOOL_NAME} for status checks, run/stop control. Use action='query' to inspect deployed artifacts, action='control' to activate/deactivate, enable tracing, or set log levels.
 - If testing requires API keys/credentials or can't be done locally, explain this and ask the user to test manually. Do not attempt credential-dependent tests.
 - **Selective deployment**: To test specific artifacts when full build is slow/broken, rename unneeded XMLs with \`.disabled\` suffix, build and deploy, then always restore originals before ending — including on abort/error. Log renamed files if cleanup fails.
-- Test with ${BASH_TOOL_NAME} if possible. If server errors persist that you cannot fix, end the task and ask user to fix manually.
+- Use ${HURL_TOOL_NAME} to explore and interact with HTTP APIs by sending requests and observing responses. It is not intended for writing API test suites, assertions. If the tool cannot fulfill the request or lacks the needed capability, fall back to ${BASH_TOOL_NAME} with curl. If server errors persist that you cannot fix, end the task and ask user to fix manually.
 
 ## Clean up
 - Shutdown the server using ${SERVER_MANAGEMENT_TOOL_NAME} before ending the task.

+Accept: application/json
+
+POST http://example.com/api
+Content-Type: application/json
+
+{
+  "name": "try-it"
+}
+
+When defining a request body in Hurl, you must follow strict syntax rules. For simple bodies (e.g., JSON), you can write them directly after a blank line. However, for complex or multi-line raw bodies (such as multipart/form-data, raw HTTP payloads, or content containing special characters), you MUST wrap the entire body inside triple backticks (\`\`\`).
+Failing to do this will result in parsing errors (e.g., "invalid HTTP method").
+
+Example (raw multipart body using triple backticks):
+POST http://example.com/upload
+Content-Type: multipart/form-data; boundary=----Boundary123
+
+\`\`\`
+------Boundary123
+Content-Disposition: form-data; name="file"; filename="sample.txt"
+Content-Type: text/plain
+
+hello world
+------Boundary123--
+\`\`\`
+
+Use triple backticks whenever the body spans multiple structured lines or includes boundary markers, binary-like content, or custom formatting.
+
+Avoid using unnecessary newlines in the hurl script, as they can lead to parsing issues.
