Examples
# Format JSON
python3 skills/json-formatter/scripts/json_formatter.py format --input '{"name":"test","value":123}'
# Compress JSON
python3 skills/json-formatter/scripts/json_formatter.py compress --input '{"name": "test", "value": 123}'
# Validate JSON
python3 skills/json-formatter/scripts/json_formatter.py validate --input '{"name":"test"}'
# Convert to YAML
python3 skills/json-formatter/scripts/json_formatter.py to-yaml --input '{"name":"test","items":[1,2,3]}'
# From YAML to JSON
python3 skills/json-formatter/scripts/json_formatter.py from-yaml --input 'name: test'
Use Cases
- Debug API responses - Format and inspect JSON data
- Reduce file size - Compress JSON for storage/transmission
- Validate config files - Check JSON syntax before deployment
- Convert formats - Switch between JSON and YAML for different tools
Current Status
In development.
Usage Guidance
This skill appears to do exactly what it says: format, compress, validate JSON and convert to/from YAML. Before installing or running it: 1) ensure python3 is available; install PyYAML (pip install pyyaml) if you need YAML conversion; otherwise JSON-only features work without it. 2) Be aware the script can read arbitrary local files when run with --file, so do not point it at sensitive files unless you intend to process them. 3) Fix the path mismatch in SKILL.md (it references a different path than the actual file) so the agent can invoke the script reliably. Overall the skill is coherent and contains no obvious malicious behavior.
Capability Assessment
Purpose & Capability
The name/description (JSON formatting, validation, conversion) align with the included script and requirements. Minor inconsistency: SKILL.md usage shows the script path as 'skills/json-formatter/scripts/json_formatter.py' while the repository contains 'scripts/json_formatter.py' (README also references 'scripts/json_formatter.py'). This is a packaging/path mismatch that can break execution but is not a security issue.
Instruction Scope
The SKILL.md instructions are narrowly scoped to formatting/validating/converting JSON and YAML. The runtime script will read an input string or an arbitrary local file when invoked with --file; it prints JSON-formatted results to stdout. There are no network calls, no references to unrelated env vars, and no attempts to access config or credentials. Note: reading arbitrary local files is expected for a converter but could expose sensitive files if used on secrets.
Install Mechanism
There is no install spec (instruction-only skill) and no downloads. A requirements.txt lists pyyaml; the script gracefully handles PyYAML not being installed. README suggests 'pip install pyyaml' for YAML support. This is proportionate and low-risk.
Credentials
The skill requests no environment variables, no credentials, and no config paths. This is appropriate for its stated functionality.
Persistence & Privilege
The skill does not request persistent/always presence (always:false) and does not modify other skills or system configuration. Default autonomous invocation is allowed but not in itself a red flag here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install json-wizard - After installation, invoke the skill by name or use
/json-wizard - Provide required inputs per the skill's parameter spec and get structured output
