experiments: Command for Claude Code

.cursor/commands/improvements-with-benchmarks.md

improvements-with-benchmarks is a command for Claude Code, Cursor from reliverse/experiments. It costs 0 tokens per session (2,348 once invoked), scanned A, original, MIT.

A command for improving a package library's speed through measured benchmark comparisons.

In plain words
What is it for?
Use it to identify packages to optimize, apply performance changes, and compare results before and after.
Why use it?
It helps distinguish real performance gains from changes that only seem faster, while checking for regressions.

Command for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code command (commands/*.md).

This is reliverse/experiments's own configuration. It tells Claude Code and Cursor how to work on experiments 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 experiments 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

improvements-with-benchmarks 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.

Purpose

This command guides the AI to improve a package library's performance using a systematic benchmarking approach. The goal is to ensure optimizations are measurable and don't introduce regressions.

Packages to Optimize

The following packages should be optimized in priority order (packages with older lastImproved timestamps should be prioritized):

# Package Last Improved Status Notes
0 @reliverse/dler - - -
1 @reliverse/build - - -
2 @reliverse/bump - - -
3 @reliverse/config - - -
4 @reliverse/datetime - - -
5 @reliverse/helpers - - -
6 @reliverse/mapkit - - -
7 @reliverse/matcha - - -
8 @reliverse/pathkit - - -
9 @reliverse/publish - - -

12 @reliverse/relinka - - -
13 rempts - - -
14 @reliverse/tsconfig - - -
15 @reliverse/typerso - - -

Metadata Fields:

  • Last Improved: Timestamp (CET timezone) when performance improvements were last completed (format: YYYY-MM-DD HH:mm:ss)
  • Status: Current optimization status (pending, in-progress, completed, skipped)
    • in-progress: ⚠️ CRITICAL: If a package has status in-progress, it means another AI agent is currently working on it. DO NOT select or work on packages with this status. Skip them and move to the next available package.
  • Notes: Any relevant information about the package or optimization results

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.

improvements-with-benchmarks is a command published in the GitHub repository reliverse/experiments (117 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,348 tokens. 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 2026-09-01.
