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 | $0.00010 | $0.00266 |
| Opus 5 | $0.00005 | $0.00133 |
| Sonnet 5 | $0.00002 | $0.00053 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
C/C++ LSP Setup
This command will configure your C/C++ development environment with clangd LSP and essential tools.
Installation Steps
1. Install LLVM (includes clangd)
macOS (Homebrew):
brew install llvm
Add to PATH:
echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
2. Install Additional Tools
# Static analysis
brew install cppcheck
# CMake (for compile_commands.json generation)
brew install cmake
3. Verify Installation
clangd --version
clang-format --version
clang-tidy --version
cppcheck --version
4. Generate compile_commands.json
For CMake projects:
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -B build
ln -s build/compile_commands.json .
For Make projects:
brew install bear
bear -- make
5. Enable LSP in Claude Code
export ENABLE_LSP_TOOL=1
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.

setup is a command published in the GitHub repository zircote/cpp-lsp (6 stars, last pushed 22d ago), licensed MIT. It adds 10 tokens to every session and 266 once invoked, about $0.0001 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 2026-08-31.
