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 | $0.00634 | $0.00634 |
| Opus 5.5 | $0.00254 | $0.00254 |
| Sonnet 5.5 | $0.00127 | $0.00127 |
| Haiku 4.5 | $0.00063 | $0.00063 |
Grade A, and why
copilot-tooling AGENTS.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

{{PROJECT_NAME}} — Project Guidelines
{{One-sentence description of what the project does, who uses it, and how.}}
Overall Principles (Very Important)
- ALWAYS prefer asking the user for input and clarification over making assumptions.
- ALWAYS use the question-tool (vscode/askQuestions) when asking the user questions, and always provide your recommended answer.
- ALWAYS select the appropriate skill for a specific task.
- Be EXTREMELY brief in your responses. Sacrificse grammar for brevity.
Code Style
- Avoid writing duplicated code and instead create reusable functions and utility components. Try to reuse existing code whenever possible.
- Prefer separating the code into smaller, focused files.
- Use descriptive variable and function names. Use comments only when necessary, such as when explaining complex logic or decisions.
- The project is in early development, so breaking changes are completely fine.

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.
