Description
Swiss-army knife for JSON files. Pretty-print, validate, minify, sort keys, and query with dot-notation paths. Zero dependencies.
Usage Guidance
This is a small, self-contained JSON CLI tool that behaves as described. It's appropriate to use for formatting, validating, and querying JSON. Before running: (1) avoid pointing it at sensitive system files (it will read any file path you give it), since it has file-read access; (2) be aware that specifying -o will overwrite the named file; (3) the tool runs locally and makes no network calls, so it does not exfiltrate data; (4) if you plan to let an autonomous agent run this skill, ensure the agent should be allowed to read whatever JSON files you expect it to process. Otherwise, this skill appears coherent and low-risk.
Capability Analysis
Type: OpenClaw Skill
Name: skill-3
Version: 1.0.0
The skill bundle provides a standard JSON utility. The `SKILL.md` is purely descriptive, outlining the tool's features and usage without any prompt injection attempts against the AI agent. The `main.py` script uses only standard Python libraries (`sys`, `json`, `argparse`) to perform expected JSON processing (read, parse, query, format, write). There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or other harmful behaviors. All file and data operations are consistent with the stated purpose of a JSON toolkit.
Capability Assessment
Purpose & Capability
The name/description (JSON pretty-print, validate, minify, query, sort) match the provided code and SKILL.md. The tool only reads JSON input, performs in-memory operations, and writes user-specified output; nothing requested is extraneous.
Instruction Scope
SKILL.md instructs only on reading JSON from a file or stdin, querying with dot notation, formatting, and optionally writing an output file. The code implements those behaviors and does not attempt to read other system state, environment variables, network endpoints, or exfiltrate data.
Install Mechanism
There is no install spec (instruction-only), and the included main.py is a small, self-contained Python script relying only on the standard library. No downloads, package installs, or archive extraction are present.
Credentials
The skill declares no required environment variables, credentials, or config paths and the code does not access any. The requested privileges are minimal and appropriate for a local JSON tool.
Persistence & Privilege
always is false and the skill does not modify other skills or system-wide configuration. It writes only to an output file when explicitly requested by the user.
How to Use
- Make sure OpenClaw is installed (local or Docker)
