meojson

meojson is a skill for Claude Code, Codex from MaaXYZ/MaaFramework. It costs 58 tokens per session (2,726 once invoked), scanned A, original, LGPL-3.0.

A usage guide for meojson, a C++ library used in MaaFramework to read, create, convert, and log JSON data. JSON is a text format for structured data such as objects, lists, and settings.

In plain words
What is it for?
Use it when writing MaaFramework code that parses or serializes JSON, maps structs to JSON, handles custom types, or logs JSON values.
Why use it?
It helps prevent confusion when connecting C++ types and application data to JSON. The input does not provide more specific behavior.

About the project

MaaFramework is an open-source framework for automating black-box software tests through image recognition. Developers use it to build low-code testing programs while retaining room for custom extensions and integrations. The catalogue includes skills and instructions for working with the framework through coding agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

meojson scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
