使用说明 (SKILL.md)
FormatGate
Convert data between JSON, YAML, and TOML.
Start the server
uvicorn formatgate.app:app --port 8008
Convert JSON to YAML
curl -s -X POST http://localhost:8008/v1/convert \
-H "Content-Type: application/json" \
-d '{"content": "{\"name\": \"Alice\", \"age\": 30}", "input_format": "json", "output_format": "yaml"}' | jq -r '.result'
Convert YAML to JSON
echo "name: Alice" | curl -s -X POST http://localhost:8008/v1/convert \
-H "Content-Type: application/json" \
-d "{\"content\": $(cat - | jq -Rs), \"input_format\": \"yaml\", \"output_format\": \"json\"}" | jq -r '.result'
Returns success (true/false), result (converted content), and error (if conversion failed — e.g., invalid input).
安全使用建议
This skill appears to do exactly what it says: a small local HTTP service for converting JSON/YAML/TOML. Before installing, note: (1) it will pip-install dependencies from PyPI — audit or pin versions if you require stricter supply-chain controls; (2) it uses tomllib (Python 3.11+) for TOML parsing, so ensure your python version is compatible; (3) the SKILL.md starts a web server on port 8008 — avoid binding to 0.0.0.0 on untrusted networks to prevent exposure; and (4) while behavior is coherent, always vet third-party packages (fastapi/uvicorn/pyyaml) for the environment where you'll run this service.
功能分析
Type: OpenClaw Skill
Name: formatgate
Version: 1.0.0
The 'formatgate' skill is a utility for converting data between JSON, YAML, and TOML formats via a FastAPI service. The implementation in `formatgate/app.py` uses standard libraries and safe practices, such as `yaml.safe_load`, to handle data parsing. There are no signs of malicious behavior, data exfiltration, or prompt injection vulnerabilities.
能力评估
Purpose & Capability
Name/description (format conversion) align with the included code and SKILL.md. Required binary (python) and pip packages (fastapi, uvicorn, pydantic, pyyaml) are appropriate for a small local web service that performs parsing/serialization.
Instruction Scope
SKILL.md only instructs running a local FastAPI server and calling POST /v1/convert with content/input/output fields. It does not ask the agent to read arbitrary files, environment variables, or send data to external endpoints.
Install Mechanism
Install spec uses PyPI packages via a pip-style 'uv' entry (fastapi, uvicorn, pydantic, pyyaml). This is a common and proportionate mechanism for a Python web service. No downloads from untrusted URLs or archive extraction were used.
Credentials
The skill declares no required environment variables, credentials, or config paths. The code does not access secrets or other environment data.
Persistence & Privilege
The skill does not request always:true or modify other skills' configs. It runs as a normal user-started local service; autonomous invocation is allowed by platform defaults but not granted extra privileges here.
