agents.md

This Skill addresses the lack of unified behavioral guidelines for AI coding agents. In practical development, developers often need to repeatedly specify coding styles, commit conventions, security requirements, and other rules in each interaction with an AI agent. This is not only inefficient but also prone to omitting critical rules, leading to inconsistent code quality. AGENTS.md provides a set of predefined global instructions, enabling AI agents to automatically adhere to uniform rules in every session, thereby reducing repetitive communication and enhancing collaboration consistency.

Usage is straightforward: simply place the AGENTS.md file in the root directory of your project. AI agents (such as Claude Code, OpenCode, etc.) will automatically read this file upon startup and apply it as system-level instructions. Subsequently, you can use natural language commands to request the agent to perform tasks like code review, submitting PRs, running tests, etc. The agent will automatically follow the rules defined in the file, such as "tests must be run before committing" or "PR descriptions must include a change list." You can also modify the file at any time to adjust rules without restarting the session.

It is particularly suitable for teams or individual developers who need to uniformly manage the behavior of multiple AI agents. This includes developers already using tools like Claude Code, OpenCode, or Codex for coding collaboration, as well as teams looking to automate coding standards, security policies, and workflow conventions. For organizations with multiple projects, each with its own specifications, you can create independent AGENTS.md files for each project to achieve granular management.

It is recommended to include AGENTS.md in version control during project initialization and update it regularly based on team standards. Note that it primarily relies on native support for the AGENTS.md file by AI agents. While mainstream agents like Claude Code already support it, some agents may require manual configuration of the loading path. Additionally, instructions should be expressed clearly and unambiguously to avoid misinterpretation by the agent. For sensitive operations (such as deleting files or modifying production environment configurations), it is advisable to explicitly prohibit them or require secondary confirmation in the file.
