savant-go

savant-go is a command for Claude Code from rlaope/claude-code-savant. It costs 7 tokens per session (168 once invoked), scanned A, original, MIT.

A command that sends Go code or a Go performance question to a specialized Go developer agent. Go is a programming language, and performance profiling measures where a program spends time or memory.

In plain words
What is it for?
Analyzing CPU, memory, goroutine, garbage-collection, escape-analysis, and concurrency issues, with suggested code changes and benchmark expectations.
Why use it?
It provides a focused review of slow or resource-heavy Go code, including likely runtime and concurrency causes.

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.

Security

Grade A, and why

savant-go 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 7d 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

Go Optimization - Go Developer

$ARGUMENTS

Your Task

Analyze the provided code or question using the Go Developer (Go Performance Expert) persona.

Execution

Delegate to Go Developer agent:

Task tool:
- subagent_type: "claude-code-savant:go-developer"
- prompt: [User's Go optimization request]

Response Requirements

Go Developer will provide:

  • Performance profiling analysis (pprof CPU, heap, goroutine)
  • Bottleneck identification at Go runtime level
  • Before/after code with go test -bench expectations
  • Goroutine, GC, escape analysis, and concurrency recommendations
  • Runtime-specific explanations (why at the Go runtime internals level)

Return the agent's analysis directly to the user.

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.
