legal-law-research

legal-law-research is a skill for Claude Code from modu-ai/moai-cowork. It costs 366 tokens per session (3,734 once invoked), scanned A, original, Apache-2.0.

A legal research tool for finding and checking South Korean laws, court decisions, administrative rules, local ordinances, treaties, and official interpretations. It can also verify whether cited provisions or decisions exist and are still applicable.

In plain words
What is it for?
Use it to retrieve statute text, search decisions, verify citations, check which law applied at a past date, compare old and new provisions, and trace how rules affect one another.
Why use it?
It helps reduce mistakes caused by outdated or incorrect legal references by checking official source text and historical applicability. It is an AI-assisted research aid, not legal advice.

    Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

legal-law-research 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 8d 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.
