What is Echo Skill?
Echo Skill serves as a foundational diagnostic tool within the Openclaw Skills ecosystem. It provides a simple HTTP interface that accepts text input and returns it exactly as received, making it an essential component for developers building or debugging agentic integrations. By offering a predictable response loop, it allows engineers to isolate networking issues from logic errors.
Built for the modern AI development lifecycle, this skill ensures that your infrastructure correctly handles JSON payloads and schema validation before you deploy more complex, production-grade skills. It is the perfect starting point for anyone setting up a local or distributed Openclaw Skills environment.
Echo Skill Use Cases
- Connectivity Validation: Instantly verify that your environment can reach external HTTP services.
- Pipeline Debugging: Test the full agent-tool invocation lifecycle without side effects.
- Parameter Verification: Confirm that complex string parameters are being passed and escaped correctly.
- Schema Testing: Validate that your JSON request and response schemas are being enforced correctly.
How Echo Skill Works
- The user or agent initiates a POST request containing a JSON payload with a
contentstring. - The Echo Skill receive the request at the
/echoendpoint. - The skill parses the input and prepends the prefix "Echo: " to the original content.
- A JSON response is generated and returned to the caller, confirming a successful round-trip.
Echo Skill Setup
To integrate this utility into your Openclaw Skills workflow, ensure your environment can reach the designated endpoint and configure your agent with the following technical specifications:
# Example request using cURL
curl -X POST http://localhost:PORT/echo \
-H "Content-Type: application/json" \
-d '{"content": "Openclaw Skills testing"}'
Echo Skill Data Schema & Taxonomy
The skill utilizes a strict JSON structure to ensure compatibility across various Openclaw Skills implementations:
| Attribute | Type | Description |
|---|---|---|
content |
String | (Input) The raw text payload to be mirrored back. |
message |
String | (Output) The resulting string containing the echoed text. |
Content-Type |
Header | Must be set to application/json for all requests. |
Echo Skill Advanced Features
- Predictable Debugging: Zero-logic response makes it the ideal baseline for latency testing within Openclaw Skills.
- Seamless Integration: Compatible with any AI agent or automation platform that supports standard HTTP POST methods.
- Diagnostic Hooks: Can be used as a health check endpoint to verify that a custom skill host is online and responsive.
