Usage
CLI Pipeline
# Run standalone
echo '\x3Cinput>' | expanso-edge run pipeline-cli.yaml
MCP Pipeline
# Start as MCP server
expanso-edge run pipeline-mcp.yaml
Deploy to Expanso Cloud
expanso-cli job deploy https://skills.expanso.io/json-to-yaml/pipeline-cli.yaml

Usage Guidance
This skill is coherent and minimal: it converts JSON to YAML and requires expanso-edge to run the provided pipelines. Before using it, decide whether you will run it locally or deploy to the cloud: running the MCP pipeline will open an HTTP server on 0.0.0.0 (default port 8080) — ensure appropriate firewalling or bind to a safer interface/port if you don't want it publicly reachable. If you deploy the job to Expanso Cloud, your input JSON will be sent to a remote service — do not send sensitive data unless you trust the deployment target. Finally, install expanso-edge from a trusted source (verify the binary origin) before running the pipelines.
Capability Analysis
Type: OpenClaw Skill
Name: expanso-json-to-yaml
Version: 1.0.0
The skill bundle is designed to convert JSON to YAML format, providing both a CLI and an HTTP server pipeline. All files, including the Expanso pipeline definitions (`pipeline-cli.yaml`, `pipeline-mcp.yaml`), `SKILL.md`, and `README.md`, are consistent with this stated purpose. The pipelines use Expanso's domain-specific language for data processing, which handles JSON parsing and YAML formatting without any indications of external calls, file system access beyond standard I/O, shell command execution, or other high-risk behaviors. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, prompt injection attempts against the agent, or obfuscation.
Capability Assessment
Purpose & Capability
Name, SKILL.md, and included pipeline YAML files all implement a JSON→YAML conversion for CLI and MCP modes. Required tooling (expanso-edge) is consistent with the pipelines; nothing unrelated is requested.
Instruction Scope
Runtime instructions are focused on conversion and reference only the provided pipeline files. The MCP pipeline will start an HTTP server bound to 0.0.0.0:${PORT:-8080} and expose /convert (POST) — this is expected for a server mode but may expose the service to the network if run without firewalling. The SKILL.md also suggests deploying the pipeline to Expanso Cloud, which would send user input to a remote service; users should consider data sensitivity before deploying.
Install Mechanism
No install spec or third-party downloads are included in the skill bundle (instruction-only). The only external dependency is the expanso-edge binary, which is noted in SKILL.md — this is proportional and transparent.
Credentials
The skill declares no environment variables, credentials, or config paths. The pipelines use only input content and create metadata (trace_id, timestamp) locally. No extraneous secrets are requested.
Persistence & Privilege
The skill does not request persistent presence (always:false), does not modify other skills or system-wide configs, and contains no installation steps that write back credentials or change agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install expanso-json-to-yaml - After installation, invoke the skill by name or use
/expanso-json-to-yaml - Provide required inputs per the skill's parameter spec and get structured output
