Guidance for AI coding agents working with this repository. Note: CLAUDE.md is a symlink to this file. This project uses pnpm for dependency management and task execution. Use the Node.js version declared in .node-version, then install dependencies with pnpm install. Run tasks with pnpm. Before completing any task, run pnpm test to ensure CI passes. This repository uses Release Please on main. If you change shipped skill contents under skills/, make sure the change is represented with an appropriate conventional…

Always run pre-commit run --all-files before creating or amending a commit. This ensures all markdown files conform to the pinned mdformat 0.7.21 formatter (--number --wrap 80 with gfm + frontmatter plugins). The hook installs its own isolated venv — do not run local mdformat directly. If the hook modifies files, stage the changes and amend your commit. Security invariants (INV-1 through INV-6) are enforced deterministically by the Google ADK Python runtime, Pydantic schemas, and tool wrappers rather than prompt fences:

The nine built-in NeMo Agent Toolkit agent types: when to pick which, key traits, and YAML examples. Companion: additional-agent-types.md lists the lesser-used types in detail. Classify the workflow shape before scaffolding: Alternates between reasoning and acting: think -> call tool -> observe result -> repeat until done (up to max_tool_calls, default 15). Use when: Tasks require interleaved reasoning over intermediate tool results; the LLM does not reliably support native tool calling (ReAct falls back to text-based Action:/Action Input: parsing); tools…

All changes require human review. Breaking changes to public API require a major version bump — always warn if binary compatibility is affected. Also consult .AGENTS.md / ~/.AGENTS.md if present for local agent settings. Architecture: Multi-module Gradle project: bson → driver-core → driver-sync/driver-reactive-streams → language wrappers (driver-kotlin-sync, driver-kotlin-coroutine, driver-scala). See .agents/references/project-guide for module structure and dependency graph. Each module has its own AGENTS.md. The default branch is main (not master). Always use main when comparing, diffing, or creating branches. -…

CLAUDE.md vs AGENTS.md

About AGENTS.md

What is AGENTS.md?

An open format for instructions to coding agents, read by Codex, Cursor and others. Think of it as a README written for agents.

Where does it go?

At the repository root, with more specific files in subdirectories. Agents read the one closest to the file they're editing.

What should it contain?

Setup and test commands, code style, and the rules a new contributor would need to know.

Does Claude Code read it?

Claude Code reads CLAUDE.md. A one-line CLAUDE.md that points at AGENTS.md covers both.
