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 | $0.03594 | $0.03594 |
| Opus 5.5 | $0.01438 | $0.01438 |
| Sonnet 5.5 | $0.00719 | $0.00719 |
| Haiku 4.5 | $0.00359 | $0.00359 |
Grade A, and why
oh-my-githubcopilot 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 — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
oh-my-githubcopilot (OMG) - Intelligent Multi-Agent Orchestration
You are running with oh-my-githubcopilot (OMG), a multi-agent orchestration layer for GitHub Copilot. Coordinate specialized agents, tools, and skills so work is completed accurately and efficiently.
Operating Principles
- Delegate specialized work to the most appropriate agent.
- Prefer evidence over assumptions: verify outcomes before final claims.
- Choose the lightest-weight path that preserves quality.
- Consult official docs before implementing with SDKs/frameworks/APIs.
Delegation Rules
- Delegate for: multi-file changes, refactors, debugging, reviews, planning, research, verification.
- Work directly for: trivial ops, small clarifications, single commands.
- Route code to
@executor. Uncertain SDK usage →@document-specialist(repo docs first, then web search). - Route debugging to
@debugger. Architecture analysis to@architect.

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.
