The following instructions are only to be applied when performing a code review. Use .github/skills/code-review/SKILL.md for repository-fit, differentiation, provenance, validation, and editorial-quality review criteria. Apply the deterministic file-format checks below as well. Frontmatter must be valid YAML and satisfy the required fields, types, lengths, and naming rules. Accept any valid YAML scalar style (plain, single-quoted, double-quoted, literal, or folded); do not flag a value solely because it is not single-quoted. Only apply to files that end in .prompt.md Only apply…

gh-aw / templates

github/gh-aw/.squad/templates/copilot-instructions.md

You are working on a project that uses Squad, an AI team framework. When picking up issues autonomously, follow these guidelines. IMPORTANT — run this check on EVERY session start, before doing any work: Inspect your agent_instructions for the coordinator canaries. This is a two-state payload-integrity check within a known Squad coordinator session; it verifies whether the coordinator payload loaded fully or was visibly truncated. It is not proof that an agent with no canaries is safely non-Squad — wholly…

squad

github/squad/.github/copilot-instructions.md

If you are a named squad agent (a cast name in .squad/casting/registry.json): This directive exists because .github/copilot-instructions.md is injected into ALL Copilot sessions globally. Agent-specific personas live in .squad/agents/*/charter.md — that is the authoritative source of identity. Skip this section if you are a named Squad agent — your charter governs you. If you are a generic Copilot CLI session, check routing before handling any non-trivial task: Full routing rules and examples: .github/instructions/squad-routing-guard.instructions.md Full routing table: .squad/routing.md Check your profile…

copilot-cli-for-beginners

github/copilot-cli-for-beginners/.github/copilot-instructions.md

These instructions guide GitHub Copilot when working in this repository. This is a beginner-friendly educational course teaching GitHub Copilot CLI. The repo contains Markdown chapters (00–07), Python/C#/JavaScript sample apps, and supporting assets (images, demo GIFs, glossary). It is not a software product — it is technical courseware. These patterns were mined from actual PR review feedback and represent recurring maintainer expectations: Every chapter (00–07) follows the same pattern in its README.md: Do not deviate from this structure when editing or…

gh-stack

github/gh-stack/.github/copilot-instructions.md

A Go CLI extension (gh stack) for managing stacked branches and pull requests. Uses Cobra for commands, bubbletea/lipgloss for TUI, and stretchr/testify for tests. Repository operations require Git 2.36+. Run vet before tests. See CONTRIBUTING.md for canonical/targeted commands and runner details. Do not add t.Parallel to tests that change Git mocks, cwd, or environment variables. No Makefile, no code generation, no external linter config. Standard Go toolchain only.

codeql-action

github/codeql-action/.github/copilot-instructions.md

The CodeQL Action is used in GitHub Actions workflows to run CodeQL scans using the CodeQL CLI. The main codebase of the CodeQL Action is written in TypeScript and compiled to JavaScript. Both the TypeScript sources and the generated JavaScript code are contained in this repository. The TypeScript sources are contained in the src directory and the JavaScript code is contained in the lib directory. A GitHub Actions workflow checks that the JavaScript code in lib is up-to-date. Therefore, you…

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.
