drift: Instructions file for GitHub Copilot

.github/instructions/drift-quality-workflow.instructions.md

drift drift-quality-workflow.instructions.md is an instructions file for GitHub Copilot from mick-gsk/drift. It costs 1,887 tokens per session, scanned A, original, MIT.

A required review process for non-trivial changes in the Drift repository, including features, refactoring, tests, CI, releases, prompts, and agent logic.

In plain words
What is it for?
Use it for changes that may affect behavior, architecture, input/output, testing, automation, or release paths. Small text edits and low-risk renames can use a reduced process.
Why use it?
It adds an adversarial second review, repeated fix cycles, an explicit approval status, and human review before merging. It also helps decide which kinds of work should be handled first.

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-quality-workflow.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 Quality Workflow — Verbindlicher Arbeitsstandard

Dieser Standard gilt workspace-weit für alle nicht-trivialen Änderungen an Code, Architektur, Tests, Refactorings und Features. Er ist kein Vorschlag — er ist bindend.


Geltungsbereich

Dieser Workflow ist Pflicht, wenn mindestens einer dieser Punkte zutrifft:

  • neues Feature oder neue Benutzerwirkung
  • Refactoring mit möglichem Verhaltenseinfluss
  • Bugfix mit nicht-trivialem Impact
  • Architektur-, Integrations- oder I/O-Änderung
  • Änderung an Tests, CI oder Release-/Packaging-Pfaden
  • Änderung an Prompt-, Agenten-, Skill- oder Automationslogik

Dieser Workflow kann reduziert werden bei:

  • kleinen Textkorrekturen
  • harmlosen Renames ohne Seiteneffekte
  • rein mechanischen Änderungen mit nachweislich geringem Risiko

Zweifel → voller Workflow.


Aufgaben-Priorisierungsreihenfolge (Feature-First-Bias vermeiden)

Bevor eine Aufgabe begonnen wird, gilt folgende feste Reihenfolge:

  1. Kritische Bugfixes
  2. Audit-Artefakte und Dev-Infrastruktur (Tests, CI) — Voraussetzung für alles andere
  3. Signal-Features als Tracer Bullet (dünner End-to-End-Slice zuerst)
  4. Vollständige Feature-Implementierung
  5. Refactoring und Polish

Agenten wählen ohne explizite Reihenfolge typischerweise die „interessanteste“ Aufgabe und überspringen dabei notwendige Infrastruktur. Diese Reihenfolge verhindert das.


Verbindlicher Standardprozess (7 Stufen)

Stufe 1 — Dual-Agent-Implementierung

Jede relevante Aufgabe wird mit zwei Rollen bearbeitet:

  • Implementierer-Rolle: setzt die Änderung um
  • Reviewer-Rolle (adversarial): sucht aktiv nach Bugs, Logiklücken, Spezifikationsverletzungen, riskanten Annahmen, Regressionen und fehlenden Tests

Die Reviewer-Rolle nimmt gezielt eine Gegenposition ein. Ziel ist nicht Bestätigung, sondern Schwachstellenfindung.

Stufe 2 — Iterativer Review-Loop

Implementierung und adversarialer Review laufen in Schleifen, bis die Lösung:

  • fachlich konsistent ist
  • technisch plausibel ist
  • hinreichend robust ist

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.
