Personal-AI-Router

NVIDIA/Personal-AI-Router/AGENTS.md

Guidance for agents and contributors working in the NVIDIA Personal AI Router (PAIR) repository. It holds an Electron desktop application and the Go services it runs on, built from one checkout. This file is the short orientation. CONTRIBUTING.md is the contribution policy and Developer Guide is the code tour; both are normative where this file is only a summary. .cursor/rules/ is not advisory. Those files record the boundaries the code is actually held to — process ownership, IPC shape, typing…

- Telemetry scope stacks must use std::thread_local! through ScopeStack; do not replace them with thread_local::ThreadLocal, whose metadata can cause false sharing on these hot paths. - UserSpan::deferred() creates a stable request root that can be captured by telemetry contexts before activate() makes the sampling decision. - TelemetryContext::with_user_span() attaches an explicit UserSpan without changing ambient scope; the returned context and handle share the same underlying span. - A deferred root is an inactive span in a shared RwLock. Activation replaces it…

This project is a mixed JetBrains MPS + plain Java/Kotlin codebase. Developers use two environments against the same checkout: - IntelliJ IDEA for editing, debugging, testing, and inspecting Java/Kotlin code, including code generated by MPS. - JetBrains MPS for editing languages, models, generators, and other MPS artifacts. Use IDEA tools for JVM work and the full MPS MCP toolset for model work. Use this file as the cross-environment entry point. For any MPS work, load the mps-mcp-workflow skill; it holds…

mongo-php-library

mongodb/mongo-php-library/AGENTS.md

The official high-level MongoDB PHP library (mongodb/mongodb). It provides a full-featured, typed API — clients, databases, collections, GridFS, change streams, bulk writes, codecs — on top of the low-level mongodb extension. The extension is a separate repository (mongodb/mongo-php-driver). It owns the wire protocol, connection management, and BSON encoding. This library builds the server commands and implements the operation-level behaviour on top. A change to how a command is executed or how BSON is encoded belongs in the extension; a change…

Google DeepMindAGENTS.md

mujoco_warp

google-deepmind/mujoco_warp/AGENTS.md

See README.md for development setup. @CONTRIBUTING.md - PR body should be plain, concise prose. Describe the problem, what the change does, and any non-obvious tradeoffs. Bullet points listing changes are fine, but avoid section headers, structured templates, and emojis. A good PR description reads like a short paragraph to a colleague, not a form. - PR and commit messages are rendered on GitHub, so don't hard-wrap them at 88 columns. Let each sentence flow on one line.

This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in node_modules/next/dist/docs/ (resolved from this file's directory; in monorepos the next package may not be visible from the repo root) before writing any code. Heed deprecation notices. This block is written and re-added by next dev — verify at node_modules/next/dist/server/lib/generate-agent-files.js.

The Java client is a port of the JavaScript client in ../playwright/packages/playwright-core/src/client/. When implementing or changing a method, read the corresponding JS file first and mirror its logic. Project checkouts (including the upstream playwright repo) live in the parent directory (../). Use the gh cli to interact with GitHub. The tests are in playwright/src/test/java/com/microsoft/playwright/. A test is a @PlaywrightTest method that takes the fixtures it needs as parameters, resolved by type: Page page, BrowserContext context, Browser browser, BrowserType browserType, Playwright…

These rules say how to write playwright/src/test/java/com/microsoft/playwright/tests/{page,library} from tests/page and tests/library in microsoft/playwright (the checkout in ../playwright; the commit the port is based on is in upstream_base.txt, together with the commands that list the upstream changes still to port). Use them for every new or changed upstream test. The port is line by line, with zero deviations. A reviewer reads the .spec.ts file and the .java file side by side. Each upstream statement maps to one Java statement, or to…

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.
