TokenEconomizer

microsoft/TokenEconomizer/CLAUDE.md

A plugin for Claude Code, Codex, the Copilot CLI and Pi (experimentally opencode, Cursor, Grok Build, Hermes Agent, the Antigravity CLI and Factory Droid) that reads finished sessions and changes what later sessions in the same repository pay for: micro-skills, tool pruning, and a loop guard. See README.md for the overview and the method, docs/PLUGIN.md for the design and the verified agent behavior, and docs/ARCHITECTURE.md for how the package fits together.

poml

microsoft/poml/CLAUDE.md

POML (Prompt Orchestration Markup Language) is a structured markup language for advanced prompt engineering with LLMs. It provides an HTML-like syntax with semantic components, comprehensive data handling, and a CSS-like styling system.

poml / poml-browser

microsoft/poml/packages/poml-browser/CLAUDE.md

This file provides guidance to Claude Code when working with the POML browser extension package. The POML Browser Extension (packages/poml-browser/) provides POML support in web browsers through a Chrome extension. It enables users to extract content from web pages, manage it as cards, and convert it to POML format. Important notes on building and testing for Claude: As developers usually run a long-running watch process, please do not emit build commands by yourself. Do not run tests on your own.…

Power-Fx

microsoft/Power-Fx/CLAUDE.md

Power Fx is a low-code general-purpose programming language based on spreadsheet-like formulas. This is the open-source C# implementation used across Microsoft Power Platform. The codebase contains a complete compiler and interpreter. Build configurations: Debug/Release (single-target), Debug462/Release462 (net462 only), Debug70/Release70 (net7.0 only), DebugAll/ReleaseAll (multi-target, used by local build scripts). Separation of Compilation and Execution: Core compiles to IR with zero evaluation code. Multiple backends (JavaScript, SQL, etc.) can consume the same IR independently. Symbol Table Composition: Layered symbol tables (Config ->…

Power-Fx / src

microsoft/Power-Fx/src/CLAUDE.md

Power Fx is a low-code general-purpose programming language based on spreadsheet-like formulas. This is the open-source implementation of the language used across Microsoft Power Platform. The codebase contains a complete compiler and interpreter infrastructure written in C#. Note: The runLocalTests.cmd script runs tests for both .NET Framework 4.6.2 and .NET 7.0 configurations using VSTest. The Power Fx implementation follows a classic multi-phase compiler architecture: Expression Text → [Lexer] → Tokens → [Parser] → AST → [Binder] → Typed AST →…

playwright-dotnet

microsoft/playwright-dotnet/CLAUDE.md

DriverVersion in src/Common/Version.props is the microsoft/playwright commit that the driver, the generated API and the port come from. .upstream/ (gitignored) is a clone of microsoft/playwright at that commit: ./build.sh --build-driver clones it, checks out the commit and builds the driver from it. Run it again when DriverVersion changes, for example after a pull. Read upstream code in .upstream/; do not commit, branch or edit in it. The .NET client talks to the Node.js driver that is built from that commit.…

clarity

microsoft/clarity/CLAUDE.md

Clarity is an open-source TypeScript behavioral analytics library for tracking user interactions and session replays. Monorepo with Lerna/Yarn workspaces: Stack: TypeScript, Rollup, TSLint, Playwright, Lerna, Yarn workspaces Critical: clarity-js has two top priorities that must guide all development decisions: Rollup + TypeScript → multiple formats (CJS, ESM, IIFE minified). Build artifacts auto-cleaned to build/ or extension/ (gitignored). Build outputs per package: - clarity-js: clarity.js (CJS), clarity.module.js (ESM), clarity.min.js (minified), plus variants: clarity.extended.js, clarity.insight.js, clarity.performance.js, clarity.livechat.js, and dynamic module builds (clarity.tidio.js,…

Microsoft365DSC

microsoft/Microsoft365DSC/CLAUDE.md

The repository coding and comment rules live in AGENTS.md. Read that file first. Rules scoped to a path, including the contract for the files under Examples/, live in .github/instructions/. IMPORTANT: This project has a knowledge graph. ALWAYS use the code-review-graph MCP tools BEFORE using Grep/Glob/Read to explore the codebase. The graph is faster, cheaper (fewer tokens), and gives you structural context (callers, dependents, test coverage) that file scanning cannot. Fall back to Grep/Glob/Read only when the graph doesn't cover what…
