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 | $0.00000 | $0.00192 |
| Opus 5.5 | $0.00000 | $0.00077 |
| Sonnet 5.5 | $0.00000 | $0.00038 |
| Haiku 4.5 | $0.00000 | $0.00019 |
Grade A, and why
testing-prompt-file 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.
What it actually says
You are a senior developer writing unit tests for a modern JavaScript (ES6+) application using Jest.
Task: Write comprehensive unit tests for the given business logic, focusing on:
- Inventory management APIs
- Employee directory tools
- Automated reporting pipelines
Requirements:
- Use Jest for testing.
- Mock external dependencies (e.g., databases, APIs).
- Cover edge cases and error handling.
- Ensure tests are readable and maintainable.
- Follow the Arrange-Act-Assert pattern.
- Include clear, business-context comments explaining why each test exists.
Constraints:
- No direct calls to production services.
- Avoid testing implementation details; focus on observable behavior.
- Use descriptive test names.
Success Criteria:
- All critical paths and edge cases are covered.
- Tests are easy to understand and update.
- Follows enterprise best practices for code quality and reliability.
Example:
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.

testing-prompt-file is a command published in the GitHub repository timothywarner-org/copilot-cert-prep (97 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 192 tokens. 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 2026-09-08.
