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-session-router

v0.1.2

Published

Pi extension that uses an LLM to route new prompts into the most relevant existing session before continuing

Readme

pi-session-router

Pi extension that automatically decides whether a new prompt belongs in another existing session.

Behavior

  • intercepts a newly submitted user prompt
  • gathers recent project sessions
  • asks an LLM to choose the most relevant existing session, if any
  • switches to that session before continuing
  • if no better session exists, keeps the current one

Commands

/session-router on
/session-router off
/session-router toggle
/session-router status
/session-router threshold 0.80
/session-router notices off

Notes

  • this is an opinionated workflow extension
  • it uses an unsupported internal AgentSession hook to switch sessions invisibly during prompt interception
  • it can stay in the current session, switch to another local session, or start a new session when no good match exists
  • it keeps a lightweight cache at ~/.pi/agent/session-router-cache.json
  • routing heuristics now use exact informative-token overlap instead of loose substring matching, which avoids false CURRENT decisions on unrelated prompts

Local test

pi -e ./pi-packages/pi-session-router

Logic tests

cd pi-packages/pi-session-router
node --test tests/router-logic.test.mjs

Install from local path

pi install ./pi-packages/pi-session-router
