drift: Instructions file for GitHub Copilot

.github/instructions/drift-prompt-engineering.instructions.md

drift drift-prompt-engineering.instructions.md is an instructions file for GitHub Copilot from mick-gsk/drift. It costs 1,069 tokens per session, scanned A, original, MIT.

A set of German-language rules for creating, improving, and reviewing prompts, instructions, skills, agents, and Copilot customizations in the Drift workspace.

In plain words
What is it for?
It guides prompt structure, file scope, shared text reuse, output agreements, and checks against making up information.
Why use it?
It helps keep prompt files focused, reusable, discoverable, and less likely to produce unsupported answers.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is mick-gsk/drift's own configuration. It tells GitHub Copilot how to work on drift 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 drift 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

drift drift-prompt-engineering.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.

Drift Prompt Engineering

Diese Instruction gilt fuer Prompt-Arbeit im Drift-Workspace. Sie ergänzt den Prompt-Engineering-Modus aus .github/copilot-instructions.md und ist nicht die Single Source of Truth fuer Primitive-Wahl, Policy-Gate oder Grundregeln.

Wenn eine Regel bereits in .github/copilot-instructions.md, .github/instructions/drift-policy.instructions.md, .github/prompts/_partials/*.md oder im Skill .github/skills/drift-agent-prompt-authoring/SKILL.md steht, wird sie referenziert und nicht erneut ausformuliert.

Wenn die Aufgabe primär einen neuen oder geänderten Workflow-Prompt unter .github/prompts/ betrifft, ist der Skill .github/skills/drift-agent-prompt-authoring/SKILL.md die erste operative Referenz. Diese Instruction liefert nur die zusaetzlichen Dateiregeln.

Diese Instruction ergänzt das PFLICHT-GATE aus .github/instructions/drift-policy.instructions.md. Prompt-Arbeit ist nur zulaessig, wenn sie Erkenntnis, Vergleichbarkeit, Einfuehrbarkeit oder Signalqualitaet verbessert — nicht wenn sie nur mehr Text produziert.

Zusaetzliche Dateiregeln

  • description muss den Task-Typ, den Trigger und den Scope benennen. Beispiele: "Prompt schaerfen", "Instruction erstellen", "Skill reviewen", "Agent konfigurieren".
  • applyTo wird nur gesetzt, wenn Dateimatching wirklich gewuenscht ist; on-demand-only Regeln bleiben ohne applyTo.
  • Mehrere applyTo-Patterns werden als Array gepflegt, nicht als unleserliche Sammelzeile.
  • Datei- oder Ordnerregeln gehoeren in *.instructions.md, nicht in copilot-instructions.md.
  • Prompt-spezifische Arbeitsablaeufe gehoeren in *.prompt.md, nicht in Instructions.
  • Wiederverwendbare Operator-Abläufe mit Ein-/Ausstiegslogik gehoeren in SKILL.md.
  • *.agent.md ist nur zulaessig, wenn Kontext-Isolation oder andere Tool-Grenzen gebraucht werden.

Zusatzregeln fuer Prompt-Artefakte

  • Prompts unter .github/prompts/ benennen Ziel, Inputs, Phasen, Artefakte und Bewertungslogik explizit und verweisen fuer Standards auf Shared Partials.
  • Instructions unter .github/instructions/ bleiben kurz, datei- oder task-spezifisch und enthalten keine zweite Policy-Ebene.
  • Skills unter .github/skills/ benennen in der description klar, wann sie genutzt werden und wann nicht.
  • Field-Test-Prompts benennen immer mick-gsk/drift als Ziel fuer Findings und Issues.
  • Neue Regeln werden erst geschrieben, nachdem geprueft wurde, dass sie nicht schon in einer Single Source of Truth existieren.

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.
