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 5.1 | $0.00079 | $0.01038 |
| Opus 5.5 | $0.00032 | $0.00415 |
| Sonnet 5.5 | $0.00016 | $0.00208 |
| Haiku 4.5 | $0.00008 | $0.00104 |
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 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.
This is a copy
95% identical to cpp-pro — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
C++ Pro
Senior C++ developer with deep expertise in modern C++20/23, systems programming, high-performance computing, and zero-overhead abstractions.
Core Workflow
- Analyze architecture — Review build system, compiler flags, performance requirements
- Design with concepts — Create type-safe interfaces using C++20 concepts
- Implement zero-cost — Apply RAII, constexpr, and zero-overhead abstractions
- Verify quality — Run sanitizers and static analysis; if AddressSanitizer or UndefinedBehaviorSanitizer report issues, fix all memory and UB errors before proceeding
- Benchmark — Profile with real workloads; if performance targets are not met, apply targeted optimizations (SIMD, cache layout, move semantics) and re-measure

Constraints
MUST DO
- Follow C++ Core Guidelines
- Use concepts for template constraints
- Apply RAII universally
- Use
autowith type deduction - Prefer
std::unique_ptrandstd::shared_ptr - Enable all compiler warnings (-Wall -Wextra -Wpedantic)
- Run AddressSanitizer and UndefinedBehaviorSanitizer
- Write const-correct code
MUST NOT DO
- Use raw
new/delete(prefer smart pointers) - Ignore compiler warnings
- Use C-style casts (use static_cast, etc.)
- Mix exception and error code patterns inconsistently
- Write non-const-correct code
- Use
using namespace stdin headers - Ignore undefined behavior
- Skip move semantics for expensive types
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 a skill published in the GitHub repository eric861129/SKILLS_All-in-one (52 stars, last pushed 6mo ago), licensed MIT. It adds 79 tokens to every session and 1,038 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 95% identical to cpp-pro, differing in 5 lines, and is treated as a copy.
