Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Release validation may run on Windows as well as Linux. Keep filesystem code and tests cross-platform: use .NET path APIs instead of hard-coded separators, specify UTF-8 when text APIs would otherwise use platform-default encodings, and avoid locale-dependent or Unix-only filesystem assumptions.
MicrosoftCopilot instructionsmicrosoft/DataFactory.MCP/.github/copilot-instructions.md
M (Power Query Formula Language) is a functional, case-sensitive, lazy-evaluated language for data transformation. Used in Power BI, Excel Power Query, and Dataflow Gen2. Fabric's cloud ETL tool. Runs M queries, writes to Lakehouse/Warehouse. You define data transformations; platform handles orchestration. When these topics come up, reference the corresponding file in docs/datafactory/: For connection management (creating/listing connections, supported types, UI form), reference docs/connection-management.md. For DevOps/CI integration with Fabric.Mcp.Server (feed caching, publishing, trim safety), reference the devops.fabric-mcp-integration skill.

This document outlines the preferred coding style and conventions to be followed when generating C# code for this project. Prefer using explicit type declarations rather than var for improved readability, except for complex generic types where type inference provides cleaner code. Prefer traditional method bodies for more complex operations, but use expression-bodied members for simple one-liners. Use nullable reference types with appropriate annotations (C# 8.0+) for improved null safety. Follow the "Method_Scenario_ExpectedBehavior" pattern for test naming. Use records for DTOs…

This repository contains eight packages for Notifications, Runtime, Tooling, and five Tooling framework adapters. Observability is retired here; do not reintroduce its packages, imports, tests, or dependency edges. Follow the migration guide for microsoft-opentelemetry. Preserve historical changelogs. Build into a fresh directory and run scripts/verify_release_artifacts.py DIRECTORY --version VERSION before any artifact promotion or upload; never reuse old dist/* release inputs.

Monorepo of 12 Python namespace packages under pctasks/, each independently installable via hatchling. Dependency order: core → cli → task → client → ingest → ingest_task → dataset → run → notify → router → server → dev. Additional code in pctasks_funcs/ (Azure Functions), datasets/ (~60 dataset definitions), and deployment/ (Terraform/Helm). Core data flow: blob storage assets → splits (by prefix) → chunks (file listing CSVs) → Collection.create_item() produces pystac Items → ingest into PgSTAC via pypgstac. Key abstractions: -…
MicrosoftCopilot instructionsmicrosoft/sqlsimtools/.github/copilot-instructions.md
This is the umbrella repository for a family of independent SQL Server testing / benchmarking tools. Each tool lives in its own top-level folder and ships with its own build, test, publish, and Copilot guidance. The root only owns cross-tool documentation, the release packager, and shared agent customization. When the user is working inside a specific tool's subfolder, prefer that tool's .github/copilot-instructions.md over this file. This file is the contract for cross-cutting / multi-tool work. Agents are the fourth way…

The DocumentDB extension for Visual Studio Code: a DocumentDB and MongoDB GUI for Azure DocumentDB, DocumentDB and MongoDB. TypeScript (strict mode), React webviews, Vitest testing. ⚠️ NEVER use npm run compile - always use npm run build to build the project. Start npm run watch:views, then open http://localhost:18080/scenarios/. Use /<view>/<scenario>/<theme> (dark, light, high-contrast); never add query strings. Fetch /scenarios/run-all.js and execute it outside the page with a Playwright page; it drives typed steps, waits for data-ready, and reports assertions/errors/host calls.…

These instructions apply to Copilot agents working in this repo — both agents writing code and agents reviewing pull requests. The PR-review rules below are review-only. The "Nits" and "Architecture & structural soundness" sections apply to both writers (follow them when generating new code) and reviewers (see Reviewer etiquette for when to surface them). Trident formats with rustfmt (workspace-wide — see rustfmt.toml). Everything below is in addition to cargo fmt and is aspirational: real files don't follow every rule 100%…
MicrosoftCopilot instructionsmicrosoft/eslint-plugin-fluentui-jsx-a11y/.github/copilot-instructions.md
This is @microsoft/eslint-plugin-fluentui-jsx-a11y, a static AST checker (ESLint plugin) that enforces accessibility rules on Fluent UI React v9 (@fluentui/react-components) JSX elements. Rules are written in TypeScript and target specific Fluent UI components to ensure accessible labeling, ARIA usage, and semantic structure. Most accessibility rules in this plugin check whether a component has an accessible label. Use makeLabeledControlRule from lib/util/ruleFactory.ts: When the factory pattern does not fit, use ESLintUtils.RuleCreator.withoutDocs:

The Microsoft Agent 365 SDK (C#/.NET) extends the Microsoft 365 Agents SDK with enterprise capabilities across three modules: Notifications, Runtime, and Tooling. Packages publish to NuGet under the Microsoft.Agents.A365.* prefix. Observability is maintained in the Microsoft OpenTelemetry .NET distro. Do not reintroduce retired Observability projects or packages here; see migration guidance. All commands run from the repository root unless noted. Requires the .NET 8.0.100 SDK (pinned in src/global.json). CI (.github/workflows/ci.yml) builds and tests in Release with --no-restore/--no-build, then packs into…
