.agents/skills/golang-benchmark/SKILL.md

golang-benchmark is a skill for Claude Code from prasenjeet-symon/ogcode. It costs 104 tokens per session (3,153 once invoked), scanned A, original, AGPL-3.0.

A guide to measuring and investigating Go program performance with benchmarks and profiling. Profiling records where a program spends CPU time or memory.

In plain words
What is it for?
Use it to write and run benchmarks, inspect pprof CPU, memory, or trace profiles, compare results with benchstat, and set up benchmark checks in CI.
Why use it?
It helps compare changes, locate slow or memory-heavy code, and detect performance regressions over time.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is prasenjeet-symon/ogcode's own configuration. It tells Claude Code how to work on ogcode itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ogcode configures →

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 16d 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.

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.
