copilot-instructions: Instructions file for GitHub Copilot

.github/instructions/follow-up-question.instructions.md

copilot-instructions follow-up-question.instructions.md is an instructions file for GitHub Copilot from duthaho/copilot-instructions. It costs 382 tokens per session, scanned A, original, MIT.

Instructions that require an AI coding assistant to ask questions about context, requirements, dependencies, testing, and edge cases before writing code.

In plain words
What is it for?
Use them before code generation when you want requirements clarified and the assistant to state its confidence.
Why use it?
They reduce the risk of generating code without understanding the project's goals or constraints.

Token cost

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

copilot-instructions follow-up-question.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 6d 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.

What it actually says

Follow-up Question Instructions

Overview

Before generating code, AI must ask clarifying questions to ensure correct implementation.

Required Questions

When a user requests code generation, ALWAYS ask:

  1. Context: What is the purpose of this code in the broader system?
  2. Requirements: What are the specific requirements and constraints?
  3. Dependencies: What frameworks, libraries, or patterns should be used?
  4. Testing: What level of test coverage is expected?
  5. Edge Cases: Are there any special cases to handle?

Confidence Assessment

After gathering information, state your confidence level:

  • High Confidence (80-100%): "I understand the requirements and can proceed."
  • Medium Confidence (50-79%): "I have some questions about [X] before proceeding."
  • Low Confidence (<50%): "I need more information about [X, Y, Z] to proceed correctly."

Example Interaction

User: "Create an order processing function"

AI:

Before I create the order processing function, I need to clarify a few things:

1. What should this function do exactly? (e.g., validate order, calculate total, persist to database)
2. What is the expected input? (e.g., Order object, dict, API request)
3. Should it follow the DDD patterns in this repository?
4. What error handling is needed?
5. Should I include unit tests?

Confidence: 30% - Need more details to implement correctly.

Rules

  • Never generate code without understanding the context
  • Ask at least 2-3 questions for complex requests
  • State your confidence level explicitly
  • Confirm understanding before proceeding

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.
