contract-copilot is a skill for Claude Code, Codex from cat-xierluo/legal-skills. It costs 103 tokens per session (7,963 once invoked), scanned A, original, no licence file.

A contract drafting and review workflow that produces risk lists, drafting outlines, suggested wording, revision advice, and review reports. It can process documents with comments or tracked revisions, including files sent through Feishu or other messaging apps.

In plain words
What is it for?
Drafting contracts, reviewing clauses, listing risks, suggesting replacement language, adding comments or revisions, and returning a revised document with a review report.
Why use it?
It turns a contract into specific issues and proposed changes instead of leaving the reviewer to find and phrase every problem manually.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/review/apply_review_plan.py \.

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

contract-copilot 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 12d 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.
