Canonical guidance

Follow the always-on Cost-Aware AI Instructions. For task-class routing (low / medium / high), see Model and Agent Routing.

Core Principle

Avoid: expensive model + large repository context + vague task.

Quick rules

Autocomplete for routine coding
Lightweight models for small edits
Stronger models only for architecture, hard debugging, or high-risk review
Give file or folder scope in every prompt
Split large work into smaller sessions
Use cost-conscious review prompts instead of broad repository review

Monthly Review

Download the IDE usage export (for example GitHub Copilot usage CSV) and run the monthly AI usage review prompt from the Guardrails plugin.

Raw content

Copy into your project — e.g. .instructions.md, .agent.md, or SKILL.md
