golang-benchmark

golang-benchmark is a skill for Claude Code from emilioforrer/go-stack. It costs 94 tokens per session (2,511 once invoked), scanned A, original, no licence file.

A guide to measuring and investigating the performance of Go programs through benchmarks, profiling, and trace analysis.

In plain words
What is it for?
Use it to write or compare benchmarks, inspect CPU and memory use, analyze execution traces, or investigate slow production code.
Why use it?
It helps replace guesses about slow code with measurements and makes it easier to spot performance regressions over time.

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

golang-benchmark scanned grade A with 1 finding 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.

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.
