A C++ build-and-test workflow using CMake, the tool that configures C++ builds, and CTest, the tool that runs tests. It also builds with sanitizers, which detect memory errors and undefined behavior.

Use it to perform debug builds, run the test suite, and repeat both with AddressSanitizer, UndefinedBehaviorSanitizer, and LeakSanitizer enabled.

It gives agents a consistent way to compile the project, run tests, and check for common C++ memory and runtime bugs. It reports the result of each step.

Token cost

What it costs to keep this loaded

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	$0.00004	$0.00133
Opus 5.5	$0.00002	$0.00053
Sonnet 5.5	$0.00001	$0.00027
Haiku 4.5	$0.00000	$0.00013

Security

Grade A, and why

cpp 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.

What it actually says

Run the C++ development workflow:

Debug build:

cmake -B build -DCMAKE_BUILD_TYPE=Debug
cmake --build build -j$(nproc)
ctest --test-dir build --output-on-failure

Then run sanitizers:

cmake -B build-san -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_FLAGS="-fsanitize=address,undefined,leak"
cmake --build build-san -j$(nproc)
ctest --test-dir build-san --output-on-failure

Report results for each step.

Changes

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 is a command published in the GitHub repository 2SSK/dot-files (250 stars, last pushed yesterday), licensed MIT. It adds 4 tokens to every session and 133 once invoked, about $0.0000 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.
