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 | $0.00271 | $0.00271 |
| Opus 5.5 | $0.00108 | $0.00108 |
| Sonnet 5.5 | $0.00054 | $0.00054 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
context-engineering 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 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
Github Copilot Instructions
Follow these instructions when writing code or documentation for the project.
Project goals
TODO: Describe the goals of the project
Project Structure
TODO: Describe your project structure
- Tip Are you using feature slicing or clean architecture?
- Tip Where are projects located in the directory structure?
- Tip What does each of the projects do in the solution?
Technology stack
TODO: Describe your technology stack
- Tip How do the technologies map on the project structure?
- Tip How are technologies used?
Testing the project
- Always create unit-tests for components you introduce into the application.
- After changing or introducing new logic make sure that the tests are updated to match the new situation.
- Include at least the following types of test cases:
- 1 test case for the expected use
- 1 edge case
- 1 failure case
Documenting the code
Make sure to document the code properly in the architecture documentation
located at docs/architecture. We follow the arc42 template for structuring
the architecture documentation.
When changing code, make sure to:
- Document important structures in the building blocks view
- Document important flows in the runtime view
- Update the glossary with new terms introduced in the feature
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.
