They reduce outdated or misplaced documentation when commands, flags, environment variables, behavior, or extensions change.

Instructions file for GitHub Copilot ✓ vendor

Written for GitHub Copilot: a Copilot instructions file.

This is Azure/azure-dev's own configuration. It tells GitHub Copilot how to work on azure-dev itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything azure-dev configures →

About the project

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

azure-dev documentation.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Documentation Maintenance

This repository uses a structured documentation system under docs/ at the repo root. When making changes to the codebase, keep the documentation current.

Documentation Structure

docs/
├── README.md          — Documentation index and navigation
├── concepts/          — Core mental models, terminology, feature lifecycle
├── guides/            — Task-oriented how-tos for contributors
├── reference/         — Schemas, flags, environment variables, feature status
└── architecture/      — System overviews, design context, ADRs

When to Update Documentation

  • New command or flag: Update docs/guides/adding-a-new-command.md if the pattern changes; update docs/reference/feature-status.md with the new feature's stage.
  • User-visible behavior change: Update relevant command docs/help when behavior affects workflows, especially --no-prompt or CI/script semantics.
  • New environment variable: Add it to cli/azd/docs/environment-variables.md (canonical), and keep docs/reference/environment-variables.md in sync when appropriate.
  • New extension capability: Update docs/architecture/extension-framework.md and docs/guides/creating-an-extension.md.
  • Feature stage change: Update docs/reference/feature-status.md when a feature graduates (alpha → beta → stable).
  • New concept or term: Add it to docs/concepts/glossary.md.
  • Architecture decision: Create a new ADR using the template at docs/architecture/adr-template.md.
  • New hosting target or language: Update docs/reference/feature-status.md and docs/concepts/glossary.md.
  • Product rebrand or compatibility name: Use the current product name in user-facing prose, while preserving legacy/internal identifiers only where required by code, telemetry, APIs, or compatibility.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
