MicrosoftCopilot instructionsmicrosoft/waza/.github/copilot-instructions.md
Read AGENTS.md before changing this repository. Its review-derived standards, required checks, and completion gates apply to ordinary Copilot work as well as Squad work. Keep detailed standards there; this file is the execution checklist, not a second specification. - Trace changed values through every affected consumer: native loaders, eval/task/checkpoint schemas, preflight, execution/resume, cache keys, run/regrade serialization, API, UI, exports, and documentation. Reuse shared effective-config/path/tool-name helpers; check overrides and disabled paths. - Preserve omitted/null/empty/zero/false distinctions and intentional legacy compatibility. Keep artifact…

MicrosoftCopilot instructionsmicrosoft/waza/.squad/copilot-instructions.md
You are working on a project that uses Squad, an AI team framework. When picking up issues autonomously, follow these guidelines. Before starting work on any issue: Before starting work, check your capability profile in .squad/team.md under the Coding Agent → Capabilities section. Use the squad branch convention: Example: squad/42-fix-login-validation When opening a PR: - Reference the issue: Closes #{issue-number} - If the issue had a squad:{member} label, mention the member: Working as {member} ({role}) - If this is a…

Core project guidelines, coding standards, and architecture principles are in AGENTS.md at the repo root — read it first. This file adds Copilot-specific skill activation routing and ADR guidance. Activate the relevant skill from .github/skills/ before any architecture task. When creating or updating an ADR in docs/arch/: - Use the create-adr skill. - Cover states, behaviors, outcomes, and edge cases thoroughly. - Reference prior ADRs and the FHIR specification. - If the decision obsoletes a prior ADR, update that ADR…

MicrosoftReads credentialsCopilot instructionsmicrosoft/prompty/.github/copilot-instructions.md
Prompty is being rebuilt from the ground up. The type system that originated in Prompty's TypeSpec specification is now owned in this repo and emitted through Typra. Prompty v2 uses the generated Prompty model packages as the canonical, lower-level type layer. Core principle: Prompty is a markdown file format (.prompty) for LLM prompts. The frontmatter uses Prompty's Typra-generated prompt model. The markdown body becomes instructions. The runtime loads, renders, parses, and executes prompts. Only the prompt runtime subset — not…

MicrosoftCopilot instructionsmicrosoft/CSS-Exchange/.github/copilot-instructions.md
NEVER commit, push, or create PRs without explicit user instruction. NEVER auto-fix issues found during code review. Report findings only. NEVER present code as complete without running Invoke-CodeFormatterOnFiles and SpellCheck.ps1 first. ALWAYS report findings and wait for user decision before modifying the repository. ALWAYS commit only the specific files the user requests. No extra files. ALWAYS use named parameters instead of positional parameters. ALWAYS ensure .ps1 files have UTF-8 BOM encoding. When counting code patterns (function calls, occurrences), ALWAYS exclude…
MicrosoftCopilot instructionsmicrosoft/griffel/.github/copilot-instructions.md
Griffel is a CSS-in-JS library with near-zero runtime, SSR support, and ahead-of-time compilation. It's organized as a monorepo using Nx with 16+ packages and applications including React bindings, build-time transforms, and DevTools. Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here. CRITICAL: NEVER CANCEL long-running commands. Set timeouts appropriately. When using Nx affected commands in a repository that may not have a main branch…
Microsoft AzureCopilot instructionsAzure/agent-landing-zone/.github/copilot-instructions.md
This repository follows a structured workflow based on two primary branches: All work must follow the branching, versioning, and changelog rules defined below. Unless explicitly instructed otherwise: Examples: - feature/conversation-metadata - feature/improve-chat-history Bicep and Terraform are co-maintained implementations of the same Agent Landing Zone capabilities. Every infrastructure change MUST check parity in both directions, including bug fixes, defaults, feature flags, dependencies and shared lifecycle behavior, not only new features or major/minor releases. - Update both affected providers in the same…
MicrosoftCopilot instructionsmicrosoft/clrmd/.github/copilot-instructions.md
Microsoft.Diagnostics.Runtime (ClrMD) is a .NET library for inspecting crash dumps and live processes. It provides programmatic access to CLR internals (heap, types, threads, GC roots, exceptions) similar to SOS debugging extensions. Important: ClrMD loads architecture-specific native components (DAC), so the test host must match the dump architecture. Use --arch x86 to test 32-bit dumps and --arch x64 for 64-bit. The Test.cmd/test.sh scripts handle this automatically. Dump generation: Tests generate crash dumps lazily on first run — no manual pre-build step…

MicrosoftCopilot instructionsmicrosoft/onnxruntime-genai/.github/copilot-instructions.md
This is ONNX Runtime GenAI, a high-performance inference library for generative AI models. The codebase implements the complete generative AI loop including preprocessing, ONNX Runtime inference, logits processing, search/sampling, and KV cache management. The State class hierarchy in src/models/model.h handles device-specific execution, while the Engine class in src/engine/ manages request batching and scheduling. WinML builds require explicit SDK version specification: WinML integration downloads Microsoft.Windows.AI.MachineLearning via NuGet and copies headers/libs to a local ort/ directory. Each hardware backend implements DeviceInterface (defined…

This project is the Microsoft JDBC Driver for SQL Server, enabling Java applications to interact with SQL Server and Azure SQL databases. It implements the JDBC 4.2/4.3 specification, communicating over the TDS (Tabular Data Stream) protocol. It supports features like connection pooling, Always Encrypted, Azure AD authentication, bulk copy, configurable retry logic, and idle connection resiliency. The project builds from a single Maven project (pom.xml) with multiple JRE profiles (jre8, jre11, jre17, jre21, jre25, jre26). Each profile compiles against a…

Synchronization owns maintenance of generated Teams samples in every language. The language profiles in automation/teams-sample-sync/config/targets.yml define the managed destination roots, currently samples/dotnet/teams/** and samples/nodejs/teams/**. This rule also applies to future language profiles. Outside that process, do not change any files in those roots, including implementations, project/package versions, lockfiles, shared helpers such as AspNetExtensions.cs, tests, manifests, configuration, assets, documentation, formatting, cleanup, or dependency updates. The authorized maintenance path includes the synchronization runtime and Copilot tasks assigned through workflow-generated handoff issues with…

This repository's canonical agent context lives in AGENTS.md at the repository root. Read it first. It describes the repository layout, the script conventions (docs/conventions.md), the one-command verify loop (scripts/verify.sh), and the pull-request conventions (.github/instructions/telemetry.instructions.md). These are sample scripts for educating Intune administrators; they are run in non-production / test environments only. Keep changes focused, idempotent, and consistent with the existing ## banner plus Microsoft copyright / MIT license header style. Run ./scripts/verify.sh before opening a pull request.
