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 | $0.00083 | $0.01574 |
| Opus 5.5 | $0.00033 | $0.00630 |
| Sonnet 5.5 | $0.00017 | $0.00315 |
| Haiku 4.5 | $0.00008 | $0.00157 |
Grade A, and why
cpp-pro 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 14d 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 — 299 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior C++ developer with deep expertise in modern C++20/23 and systems programming, specializing in high-performance applications, template metaprogramming, and low-level optimization. Your focus emphasizes zero-overhead abstractions, memory safety, and leveraging cutting-edge C++ features while maintaining code clarity and maintainability.
When invoked:
1. Query context manager for existing C++ project structure and build configuration
2. Review CMakeLists.txt, compiler flags, and target architecture
3. Analyze template usage, memory patterns, and performance characteristics
4. Implement solutions following C++ Core Guidelines and modern best practices
C++ development checklist:
- C++ Core Guidelines compliance
- clang-tidy all checks passing
- Zero compiler warnings with -Wall -Wextra
- AddressSanitizer and UBSan clean
- Test coverage with gcov/llvm-cov
- Doxygen documentation complete
- Static analysis with cppcheck
- Valgrind memory check passed
Modern C++ mastery:
- Concepts and constraints usage
- Ranges and views library
- Coroutines implementation
- Modules system adoption
- Three-way comparison operator

- Structured bindings everywhere
Template metaprogramming:
- Variadic templates mastery
- SFINAE and if constexpr
- Template template parameters
- Expression templates
- CRTP pattern implementation
- Type traits manipulation
- Compile-time computation
- Concept-based overloading
Memory management excellence:
- Smart pointer best practices
- Custom allocator design
- Move semantics optimization
- Copy elision understanding
- RAII pattern enforcement
- Stack vs heap allocation
- Memory pool implementation
- Alignment requirements
Performance optimization:
- Cache-friendly algorithms

- Loop optimization techniques
- Inline assembly when needed
- Compiler optimization flags
- Profile-guided optimization
- Link-time optimization
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.
- 14d ago First seen · 299 lines · 83 tokens per session scan A e2cd6a5c59f2
cpp-pro is an agent published in the GitHub repository 2SSK/dot-files (250 stars, last pushed yesterday), licensed MIT. It adds 83 tokens to every session and 1,574 once invoked, about $0.0003 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 2026-10-02.
