Q: What is AGENTS.md and why is it important for production-ready agents? A: AGENTS.md is a simple, plain-text file that provides agents with project-specific instructions, rules, and limits to help move systems from demos into stable, safe, and portable deployments. It reduces fragmentation and improves interoperability across tools and platforms by offering a single trusted source of context for agents. Q: Where should I place AGENTS.md inside my project repository? A: Place a single AGENTS.md at the repository root, or add one per service in a monorepo subfolder or service directory so agents can find the relevant context. Also state which agents should use the file and what data, tools, and environments are in scope. Q: What sections should a practical AGENTS.md include? A: Use a clear, predictable layout with concise sections such as an overview, goals and non-goals, ownership, conventions, build and run commands, testing, dependencies, tools and APIs, security and privacy, permissions, error handling, change process, and examples. Keep each section short and task-focused so agents can plan, execute, and verify work with minimal back-and-forth. Q: How should I write AGENTS.md so agents act safely and finish tasks on the first try? A: Start with a single plain-text file and keep sentences short, action-oriented, and focused on exact commands and outcomes—this is the practical core of how to use AGENTS.md in your codebase. Include concrete examples, explicit deprecated paths, and exact secrets-handling rules so agents can act reliably and avoid guesswork. Q: How can I enforce AGENTS.md in developer workflows and CI? A: Wire AGENTS.md into IDE assistants, CI checks, PR templates, linters, and observability so both agents and humans rely on the same source of truth. For example, ensure IDEs read the file at project open, fail CI if key sections are missing, require an AGENTS.md-based checklist in PRs, and tag runs with the file version for audits. Q: What guardrails should AGENTS.md define for network calls and permissions? A: Document allowed endpoints with rate limits, required auth scopes and tokens, and ban network calls outside the allowlist to prevent agents from discovering APIs by trial. Also specify allowed directories to edit, blocked files, max diff size, and clear permission boundaries for read-only versus writable resources. Q: How should teams measure the impact of AGENTS.md and keep it updated? A: Track metrics like task success rate on first attempt, average PR review comments per agent change, revert rate and production incidents, and time to ship for common tasks. Review AGENTS.md in regular engineering syncs, update it when build, test, or API steps change, and tag releases or CI logs with the file version. Q: What are common pitfalls when adopting AGENTS.md and how do I fix them? A: Common pitfalls include making the file too long (move details to linked docs), being too vague (replace “should” with exact commands), and letting it drift out of date (tie updates to PRs that change behavior). Fixes are operational: shorten the core file, add CI and linter enforcement, and place or reference service-specific files in monorepos so agents always find the right instructions.
