benchmark

benchmark is a command for Claude Code from RaNDoM6913/claude-code-superkit. It costs 9 tokens per session (1,477 once invoked), scanned A, original, MIT.

A Go benchmark runner that measures benchmark functions repeatedly, records memory statistics, and can compare results between two Git references.

In plain words
What is it for?
It runs Go benchmarks and, in comparison mode, uses benchstat to show differences between commits or branches.
Why use it?
It provides repeatable measurements for checking whether a Go code change affects speed or memory use.

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

benchmark 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 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.

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.

Go Benchmark Runner

Role

Run Go benchmarks with memory stats and 6 repetitions; in --compare mode, benchmark two git refs and diff them with benchstat. Go-only command: on non-Go projects it exits at Step 1 with zero side effects.

Hard Rules

  1. No go.mod found → report "No Go project detected" and STOP.
  2. No func Benchmark functions found → report "No benchmark functions found" and STOP.
  3. Compare mode: record ORIGINAL_REF and STASHED (Step 4) BEFORE any git checkout or git stash. Never switch first.
  4. Once Step 4 switched refs, the Restore epilogue (Step 6) ALWAYS runs — after success, after a failed benchmark run, after a missing tool, after any error. Never finish with the repo on another ref or with changes still stashed.
  5. Never run destructive git commands (reset --hard, clean -f, checkout that overwrites uncommitted changes). Uncommitted changes are preserved only via git stash push.
  6. Use the exact go test command from Step 3; do not lower -count below 6 (statistical significance needs repetitions).

Step 1 — Detect Project

  1. Find go.mod (repo root, else Glob **/go.mod). Missing → Hard Rule 1.
  2. Find benchmarks: grep -rn "func Benchmark" --include="*.go" . Zero hits → Hard Rule 2.

Done when: go.mod confirmed AND ≥1 benchmark function found (or the command stopped with the exact message).

Step 2 — Parse Arguments

Arguments: $ARGUMENTS

Input Result
(empty) PKG=./... (all packages), MODE=single
<package> PKG=<package> (e.g. ./pkg/cache/...), MODE=single
--compare <ref> MODE=compare against <ref>; PKG from remaining arg or ./...

Done when: PKG and MODE are fixed.

Step 3 — Run Current Benchmarks

go test -bench=. -benchmem -count=6 -timeout=10m <PKG>
  • MODE=single: parse output into the results table → go to Step 7.
  • MODE=compare: save raw output to /tmp/bench-new.txt. If this run FAILS, report the error and STOP here (nothing was switched yet, no restore needed).

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.

benchmark is a command published in the GitHub repository RaNDoM6913/claude-code-superkit (3 stars, last pushed 3d ago), licensed MIT. It adds 9 tokens to every session and 1,477 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-09-03.
