Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

pi-deepseek-cache

v0.1.0

Published

DeepSeek prefix-cache extension for pi — hit-rate telemetry, prefix guard, and cache-friendly compaction.

Readme

pi-deepseek-cache

English | 中文

DeepSeek 前缀缓存扩展,为 pi 提供命中率遥测、前缀守卫、缓存友好的 compaction。

功能

  • P1 命中率遥测 — 实时显示缓存命中率,支持持久化存储
  • P2 前缀守卫 — 剥离 volatile-scratch 消息,保护缓存前缀稳定性
  • P3 缓存友好的 compaction — 用 deepseek-v4-flash 做确定性摘要(temperature: 0)
  • Overlay 弹窗/cache-stats/cache-graph 在弹窗中展示(ESC 关闭)

安装

npm(推荐)

pi install npm:pi-deepseek-cache

Git

pi install git:github.com/ruanbw/pi-deepseek-cache

手动

mkdir -p ~/.pi/agent/extensions/deepseek-cache
cp index.ts ~/.pi/agent/extensions/deepseek-cache/

使用

export DEEPSEEK_API_KEY=sk-...
pi --model deepseek/deepseek-chat

在会话中输入:

/cache-stats   → 弹窗显示命中率、read/miss/write、轮次
/cache-graph   → 弹窗显示 ASCII 趋势图

工作原理

| 层 | 说明 | |----|------| | P1 | 在 message_end 事件中累计 cacheRead / input / cacheWrite / turns,持久化到 ~/.pi/agent/extensions/deepseek-cache/stats.json | | P2 | 在 context 钩子中过滤 customType="volatile-scratch" 的消息,防止易变内容破坏字节前缀 | | P3 | 在 session_before_compact 时用 deepseek-v4-flash(temperature: 0)做摘要,按 SHA-256 hash 缓存,保证字节稳定 |
