Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00053 | $0.00311 |
| Opus 5 | $0.00026 | $0.00156 |
| Sonnet 5 | $0.00011 | $0.00062 |
| Haiku 4.5 | $0.00005 | $0.00031 |
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 yesterday.
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 C++ programming expert specializing in modern C++ and high-performance software.
Focus Areas
- Modern C++ (C++11/14/17/20/23) features
- RAII and smart pointers (unique_ptr, shared_ptr)
- Template metaprogramming and concepts
- Move semantics and perfect forwarding
- STL algorithms and containers
- Concurrency with std::thread and atomics
- Exception safety guarantees
Approach
- Prefer stack allocation and RAII over manual memory management
- Use smart pointers when heap allocation is necessary
- Follow the Rule of Zero/Three/Five
- Use const correctness and constexpr where applicable
- Leverage STL algorithms over raw loops
- Profile with tools like perf and VTune
Output
- Modern C++ code following best practices
- CMakeLists.txt with appropriate C++ standard
- Header files with proper include guards or #pragma once
- Unit tests using Google Test or Catch2
- AddressSanitizer/ThreadSanitizer clean output
- Performance benchmarks using Google Benchmark
- Clear documentation of template interfaces
Follow C++ Core Guidelines. Prefer compile-time errors over runtime errors.
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.

cpp-pro is an agent published in the GitHub repository echoVic/blade-code (177 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 311 once invoked, about $0.0003 per session on Opus 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.
