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 | $0.02101 | $0.02101 |
| Opus 5.5 | $0.00840 | $0.00840 |
| Sonnet 5.5 | $0.00420 | $0.00420 |
| Haiku 4.5 | $0.00210 | $0.00210 |
Grade A, and why
skunit 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
skUnit - Semantic Testing Framework for IChatClient and SemanticKernel
skUnit is a .NET testing framework for creating semantic tests for IChatClient implementations and SemanticKernel units using markdown scenario files.
ALWAYS reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
Working Effectively
Bootstrap, Build, and Test
- Initial setup:
dotnet restore src/skUnit.sln-- takes 16 seconds. NEVER CANCEL. Set timeout to 30+ seconds. - Build the solution:
dotnet build src/skUnit.sln --no-restore-- takes 12 seconds. NEVER CANCEL. Set timeout to 30+ seconds. - Run unit tests (works offline):
dotnet test src/skUnit.sln --no-build --filter "FullyQualifiedName~JsonCheckAssertionTests|FullyQualifiedName~FunctionCallAssertionTests|FullyQualifiedName~ParseChatScenarioTests"-- takes 1 second - Full test suite (requires API keys):
dotnet test src/skUnit.sln --no-build-- requires Azure OpenAI configuration
Code Quality
- Format code:
dotnet format src/skUnit.sln-- takes 8 seconds. NEVER CANCEL. Set timeout to 30+ seconds. - Verify formatting:
dotnet format src/skUnit.sln --verify-no-changes-- fails if formatting needed - ALWAYS run
dotnet format src/skUnit.slnbefore committing changes or CI will have formatting issues
Demo Projects
- TDD REPL Demo: Located in
demos/Demo.TddRepl/- Build:
cd demos/Demo.TddRepl && dotnet restore Demo.TddRepl.sln && dotnet build Demo.TddRepl.sln --no-restore - Shows how to use skUnit for test-driven development of chat applications
- Build:
- MCP Demo: Located in
demos/Demo.TddMcp/- Shows integration with Model Context Protocol tools
- Shop Demo: Located in
demos/Demo.TddShop/- Complex multi-scenario chat testing
Requirements and Configuration
System Requirements
- .NET 8.0 (verified working with 8.0.118)
- Azure OpenAI API access (for integration tests and semantic validation)
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.
- 2mo ago First seen · 188 lines · 2,101 tokens per session scan A 2e0621000752
skunit copilot-instructions.md is an instructions file published in the GitHub repository mehrandvd/skunit (181 stars, last pushed 3mo ago), licensed MIT. It adds 2,101 tokens to every session, about $0.0084 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.
