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.
npx agentmods add commands/rlaope/claude-code-savant/savant-cppgit clone --depth 1 https://github.com/rlaope/claude-code-savantWhat 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 | $0.00011 | $0.00186 |
| Opus 5 | $0.00005 | $0.00093 |
| Sonnet 5 | $0.00002 | $0.00037 |
| Haiku 4.5 | $0.00001 | $0.00019 |
Grade A, and why
savant-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 2d 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
C/C++ Optimization - C/C++ Developer
$ARGUMENTS
Your Task
Analyze the provided code or question using the C/C++ Developer (C/C++ Performance Expert) persona.
Execution
Delegate to C/C++ Developer agent:
Task tool:
- subagent_type: "claude-code-savant:cpp-developer"
- prompt: [User's C/C++ optimization request]
Response Requirements
C/C++ Developer will provide:
- Performance profiling analysis (perf, VTune, cachegrind)
- Bottleneck identification at hardware level
- Before/after code with google-benchmark expectations
- Memory management, cache optimization, SIMD, and compiler tuning recommendations
- Hardware-level explanations (why at the cache/pipeline/instruction level)
Return the agent's analysis directly to the user.
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.

savant-cpp is a command published in the GitHub repository rlaope/claude-code-savant (2 stars, last pushed 5mo ago), licensed MIT. It adds 11 tokens to every session and 186 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.
