microcheck copilot-instructions.md

A startup checklist for an AI coding agent working on a specific repository. It requires the agent to read shared instructions from a web address and the repository's own instruction file before making changes.

In plain words
What is it for?
Use it to control the beginning of coding sessions for the Microcheck project, including which instruction files must be read before editing.
Why use it?
It prevents code changes that ignore project rules or repository-specific guidance. Loading the instructions first gives the agent the required context and constraints.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

microcheck copilot-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 2d 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.

Origin

This is a copy

95% identical to webhook-tester copilot-instructions.md — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

GitHub Copilot Instructions

At the very start of every session, before doing anything else, fetch and read the following files in order:

  1. https://tarampampam.github.io/.github/ai/AGENTS.md (mirror: https://raw.githubusercontent.com/tarampampam/.github/refs/heads/master/ai/AGENTS.md) - global agent rules
  2. AGENTS.md (repo root) - project-specific rules

Do not make any code changes until the applicable rules above have been loaded and understood.

Changes

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.
