drift: Instructions file for GitHub Copilot

.github/instructions/drift-rag-grounding.instructions.md

drift drift-rag-grounding.instructions.md is an instructions file for GitHub Copilot from mick-gsk/drift. It costs 999 tokens per session, scanned A, original, MIT.

A rule requiring agents to support claims about Drift's policies, signals, architecture decisions, audits, or benchmark evidence with retrieved project facts and citations. RAG means retrieving relevant stored information before answering.

In plain words
What is it for?
Use it whenever an agent explains or makes decisions based on Drift's internal policies, signals, ADRs, audits, or benchmark results.
Why use it?
It reduces unsupported statements about the Drift project and makes important claims traceable to checked evidence.

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-rag-grounding.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 6d 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 — RAG Grounding Contract (bindend fuer Agenten-Aussagen ueber drift selbst)

Diese Instruction erzwingt verifizierte Zitation fuer Agenten-Aussagen ueber drifts eigene Entscheidungsgrundlage. Sie ergaenzt die Drift Policy Instruction und ersetzt sie nicht.

Autoritative Quelle: ADR-091 — Drift-Retrieval-RAG.

PFLICHT-GATE: Grounding-Check

Dieses Gate zusaetzlich zum Drift Policy Gate sichtbar ausgeben, sobald eine Agenten-Antwort eine Behauptung ueber drift selbst enthaelt:

### Drift Grounding Gate
- Aussage ueber drift selbst (Policy/Signal/ADR/Audit/Evidence): [JA / NEIN]
- drift_retrieve aufgerufen: [JA / NEIN] → [Query-Text]
- zitierte Fact-IDs: [Liste mit mindestens einer ID oder "KEINE"]
- drift_cite verifiziert: [JA / NEIN / ENTFAELLT]
- Entscheidung: [ZULAESSIG / NACHZITIEREN]

Eine Antwort mit Aussage ueber drift selbst und ohne mindestens eine zitierte fact_id ist ungueltig und muss vor der Rueckgabe um den Retrieval-Aufruf ergaenzt werden.

Wann das Gate greift

Das Gate ist verpflichtend fuer Aussagen ueber:

  1. Policy-Regeln aus POLICY.md (Zulassung, Ausschluss, Priorisierung, Audit-Pflicht, Telemetrie)
  2. Signal-Rationale, Scoring-Gewichte, Scope (file_local vs. cross_file)
  3. ADR-Entscheidungen (z. B. „ADR-031 hat kNN-Semantic-Search verworfen")
  4. Audit-Artefakte (FMEA, STRIDE, Risk Register, Fault Trees)
  5. Benchmark-Evidence (Precision/Recall, Mutation-Detection, Latenz)
  6. Roadmap-Phasen und Einordnung von Features in Phasen

Das Gate greift nicht fuer:

  • Aussagen ueber den vom User analysierten Ziel-Code (dafuer drift_scan/drift_brief).
  • Allgemeine Softwareentwicklungsfragen ohne drift-Bezug.
  • Erklaerungen aus drift_explain, die bereits drifts eigene Doku-Quelle sind.

Operativer Ablauf

  1. Vor der Antwort drift_retrieve(query="<Frage in eigenen Worten>", top_k=5) aufrufen.
  2. Optional einschraenken: kind (policy|roadmap|adr|audit|signal|evidence), signal_id (z. B. pattern_fragmentation).
  3. Aus den Treffern mindestens eine passende fact_id auswaehlen.
  4. Bei Unsicherheit ueber den genauen Wortlaut drift_cite(fact_id=...) aufrufen und den text-Wert wortgetreu zitieren; der sha256-Anker macht die Zitation nachpruefbar.
  5. Fact-ID im Antworttext in Backticks fuehren, z. B. gemaess `POLICY#S8.p2` ….

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.
