A set of working instructions for an AI coding agent, covering development practices, file organisation, communication, and project constraints. It is tailored to the MaximilianMayr94/skills project.

In plain words
What is it for?
Use it when maintaining that project, following its software-development process, organising documents and folders, or creating diagrams and short project notes.
Why use it?

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is MaximilianMayr94/skills's own configuration. It tells GitHub Copilot how to work on skills 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 skills configures →

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

skills 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

General Rules

  • Communication can be nearly skipped as most of the information is in the documents.
    • Keep the final answer to the minimum, do not explain anything just write notes what was done.
  • files should be short and concise because they are processed by AI.
    • Use bullet points instead of long paragraphs.
    • Use mermaid diagrams as much as possible - pictures tell more than words
  • Do not explain everything, expect professional knowledge. But always explain referenced tools / and libraries in one short sentence
  • Reference content instead of writing it again
  • For diagrams use "mermaid" in markdown
  • Always ask for clarification if you are not sure about something. Do not make assumptions.
  • Keep your answer short, communicate in the documents/files

Constraints

  • Never change files outside of this repository
  • Use git only for read-only actions

Software Development Lifecycle - SDLC

This project follows the VAgile process. It is a combination of the traditional V-Model and the Agile process. The macro part of the project (beginning and end) follows the V-Model, while the micro part (Refinement/Implementation/Review) follows an agile methodology. The V-Model parts aim to be slow and complete, while the AGILE part aims to be quick and should be seen as prototyping.

  1. Definition (V-Model - whole project): In this phase the project context and software requirements are defined. context.md, software_requirements.md are created. (init, brainstorm, criticize skill)
  2. Architecture (V-Model - whole project): In this phase the architecture.md is defined and created from context.md and software_requirements.md. Functions are grouped in components and interfaces are defined. (architect skill)
  3. Refinement (Agile - part): In this phase the implementation/design of each *component is defined. For each component modules and units are defined. As well as data handling, interfaces and so on. So the code can be completely derived from these documents. Executed component for component. (refine, ticket_prep skill)
  4. Implementation (Agile - part): Tickets are implemented . (implement skill)
  5. Review (Agile - part): One slice is reviewed and feedback is given. The review document is created and updated. Problems, bugs, gaps and contradicting information are defined. Suggestions for improvements and changes to the architecture and refinement are given. (review skill)
  6. Verification (V-Model - whole project): The software is verified against software_requirements.md, context.md and the architecture. The verify document is created and updated. The final verification result is defined. (verify skill)

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.
