drift: Instructions file for GitHub Copilot

.github/copilot-instructions.md

drift copilot-instructions.md is an instructions file for GitHub Copilot from mick-gsk/drift. It costs 3,275 tokens per session, scanned A, original, MIT.

A required set of working rules for AI coding assistants in the Drift workspace. It tells agents how to handle prompts, instructions, skills, and agent files.

In plain words
What is it for?
Following Drift's policies while editing prompt and agent configuration files. It helps choose the right kind of instruction file and apply required prompt-writing rules.
Why use it?
It gives every agent the same rules and prevents inconsistent or weak instructions. It also directs agents to read the workspace policy before starting work.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

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 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 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 — Verbindliche Arbeitsgrundlage für alle Agenten

Diese Datei ist für alle Copilot-Agenten, Coding-Agenten und KI-Assistenten im Drift-Workspace bindend.

Die vollständige Policy befindet sich in: POLICY.md (Workspace-Root)

Lies diese Datei vor jeder Arbeit vollständig, sofern sie nicht bereits im Kontext ist. Die Policy ist ein Vertrag — keine Empfehlung, kein Vorschlag.

Primärmodus bei Prompt-Engineering

Wenn eine Aufgabe Prompts, Instructions, Skills, Agents oder diese Datei selbst betrifft, arbeitet der Agent im Prompt-Engineering-Modus. Ziel ist nicht schönere Prosa, sondern härtere, operativere und reviewbare Agentensteuerung.

Betroffene Pfade:

  • .github/prompts/**
  • .github/instructions/**
  • .github/skills/**
  • .github/agents/**
  • .github/AGENTS.md
  • .github/copilot-instructions.md

Detaillierte Zusatzregeln:

  • Routing: .github/instructions/drift-context-routing.instructions.md
  • Prompt-Engineering: .github/instructions/drift-prompt-engineering.instructions.md
  • Workflow-Skill: .github/skills/drift-agent-prompt-authoring/SKILL.md

Zuerst das richtige Primitive wählen

Bedarf Richtiges Primitive
Repo-weite, immer geltende Regeln copilot-instructions.md
Datei- oder Ordner-spezifische Regeln *.instructions.md
Wiederverwendbarer Operator-Workflow SKILL.md
Konkreter mehrphasiger Ablauf mit Ziel und Artefakten *.prompt.md
Isolierter Spezialmodus mit eigener Tool-/Kontextgrenze *.agent.md

Falsches Primitive = schwacher Prompt. Eine Datei darf nur das regeln, wofür ihr Primitive gedacht ist.

Nicht verhandelbare Schärferegeln

  1. Deutsch und modellunabhängig. Keine Modellnamen, keine vendor-spezifischen Prompt-Tricks.
  2. Description ist Discovery-Oberfläche. Das description-Feld muss Triggerwörter, Task-Typ und Scope explizit enthalten.
  3. applyTo so eng wie möglich. applyTo: "**" nur für wirklich universelle Regeln.
  4. Ein Problem pro Datei. Keine Mischdateien für Policy, Testing, Release und Prompt-Stil.
  5. Keine Parallel-Policy. Shared Partials, Policy und Push-Gates referenzieren statt duplizieren.
  6. Keine weichen Verben ohne Vertrag. Wörter wie "analysiere", "verbessere", "prüfe gründlich", "wenn möglich" oder "robust" sind nur zulässig, wenn Inputs, Schritte, Ergebnisform und Abbruchkriterium definiert sind.
  7. Keine Halluzinationsflächen. Keine erfundenen Flags, Dateien, Tools, Issue-Ziele, Pfade oder angeblich vorhandenen Artefakte.
  8. Prompts erzeugen Evidenz. Jeder Prompt muss in Beobachtung, Artefakt, Entscheidung, Maßnahme oder sauberem Abbruch enden - nie nur in Prosa.

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.
