AI Tool-Call Contract Builder for fast browser-based work
Create a tool-calling contract for AI agents: tool list, parameters, returns, errors, permission tiers, dry-run rules, human approval, audit logs, and rollback checks.
中文：为 AI Agent 生成工具调用契约：工具列表、参数、返回值、错误、权限分级、dry-run、人工批准、审计日志和回滚检查。
Example: Use it before giving an agent file access, browser access, email sending, deployment, payments, refunds, account changes, or external API calls.

Review notes
- This tool does not call external APIs or inspect live tools.

AI Tool-Call Contract Builder questions
Does it call my tools?
No. It creates a local contract for review before any tool is connected.
Why define dry-run rules?
Agents should preview dangerous operations before writing files, deploying, charging money, or changing accounts.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
