microsoft/fabric-task-flows/.github/copilot-instructions.md
This is a documentation-driven knowledge base with supporting Python scripts and tests. The repo provides pre-defined Microsoft Fabric architectures via one orchestrator agent (@fabric-advisor) that delegates to 6 composable skills. ⚠️ MUST parallelize independent work. If task B does not depend on the output of task A, they run in parallel — never sequentially. This applies to tool calls, file operations, and sub-tasks. item-type-registry.json is the single source of truth for all item metadata. Never hardcode or guess values —…

MicrosoftCopilot instructionsrego-cpp
microsoft/rego-cpp/.github/copilot-instructions.md
rego-cpp is a C++ interpreter for Rego, the policy language of Open Policy Agent (OPA). It targets Rego v1.17.1 and is designed for embedding policy evaluation directly into C++ applications, as well as for use from C, Rust, Python, and .NET via language wrappers. The interpreter is built on top of Trieste, a term-rewriting framework from Microsoft Research. Evaluation proceeds by parsing Rego source into an AST and then iteratively rewriting it through a series of compiler passes until a…

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.

microsoft/GHCP-Lab/dotNet/.github/copilot-instructions.md
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 "MethodScenarioExpectedBehavior" pattern for test naming. Use records for DTOs…

Prefer cargo-nextest if installed (faster, better output). Fall back to cargo test otherwise. Each test runtime creates a connection pool (default 10 max connections). At high parallelism (e.g., 14 cores), peak PostgreSQL connections can reach ~104. If PostgreSQL max_connections is set to the default 100, tests will fail with timeouts due to connection exhaustion. Fix: Increase PostgreSQL max_connections to at least 300:

microsoft/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.

About Copilot instructions
What is copilot-instructions.md?
Repository-wide instructions for GitHub Copilot, kept in .github/copilot-instructions.md.
What should it contain?
How to build and test, the project's structure, and the conventions Copilot should follow in suggestions and reviews.
Does it replace AGENTS.md?
No. Copilot's coding agent also reads AGENTS.md, so many projects keep the shared rules there.
Which ones worked?
