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 | $0.00680 | $0.00680 |
| Opus 5.5 | $0.00272 | $0.00272 |
| Sonnet 5.5 | $0.00136 | $0.00136 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
dark-factory 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 2mo 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot Instructions — Dark Factory
This repository contains Dark Factory, a GitHub Copilot CLI skill that orchestrates an agent pipeline with sealed-envelope testing and cross-family model independence (Shadow Score Spec v2.0, Level 4 — Adversarial Independence).

Why these decisions |
Non-negotiables
- Sealed envelope is sacred. The Lead Engineer must never see sealed tests; the QA Sealed agent must never see code. Isolation is filesystem topology (vault outside the repo, disposable verify worktree), not prompt wording.
- Model independence is sacred. Seal author and implementer must be in different families. Same-family pairing biases every Shadow Score toward 0% — it overclaims quality. Phase 0 aborts on violation.
- Config is the source of truth. Never hardcode model names or tunables inside prompts.
- Agent prompts <= 200 lines. If a prompt grows, split responsibilities instead.
- Just a skill. Do not add runtime code, package managers, telemetry, dashboards, or plugin systems. The one exception is
.github/scripts/validate_conformance.py, which runs in CI only and must stay dependency-light. - Worktree isolation. All build work happens under
.factory/until delivery approval. - Delivery is always human-approved, in every autonomy mode including
dark.
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.

dark-factory copilot-instructions.md is an instructions file published in the GitHub repository DUBSOpenHub/dark-factory (27 stars, last pushed 2d ago), licensed MIT. It adds 680 tokens to every session, about $0.0027 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.
