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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00780 | $0.00780 |
| Opus 5.5 | $0.00312 | $0.00312 |
| Sonnet 5.5 | $0.00156 | $0.00156 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
drift drift-context-routing.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.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kontext-Routing — Welche Regeln gelten wann?
Zweck: Nicht alle Instructions und Skills sind für jede Aufgabe gleich relevant. Diese Datei hilft dem Agenten, den Fokus auf die wichtigsten Regeln zu legen.
Diese Datei definiert kein eigenes Regelwerk. Sie ist ein Routing-Index und verweist auf die jeweils autoritativen Dateien.
Schneller Einstieg: Fuer kompakte Task-zu-Gate Zuordnung ohne vollstaendiges Routing nutze .github/instructions/drift-agent-quickref.instructions.md.

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.
- 1mo ago First seen · 44 lines · 780 tokens per session scan A 482d1234c1bc
drift drift-context-routing.instructions.md is an instructions file published in the GitHub repository mick-gsk/drift (16 stars, last pushed 2mo ago), licensed MIT. It adds 780 tokens to every session, about $0.0031 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
