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 🙏

Readme

pi-compass

Codebase navigation for Pi coding agent sessions. Generates structured codemaps and interactive code tours so agents (and developers) can orient themselves in unfamiliar repos without burning tokens on exploration.

Installation

pi install npm:pi-compass

Usage

Generate a codebase map

/onboard

Analyzes the current repo and generates a structured map covering:

  • Directory structure
  • Package managers and dependencies
  • Detected frameworks
  • Entry points
  • Build, test, and deploy scripts
  • Coding conventions (from AGENTS.md, CLAUDE.md, lint configs, etc.)
  • Key files (README, LICENSE, CI configs, etc.)

The map is cached and automatically injected into the agent's system prompt on the first turn of each session.

Force regeneration

/onboard --refresh

Take a code tour

/tour              # list available topics
/tour auth         # guided walkthrough of the auth module
/tour testing      # walkthrough of test infrastructure
/tour ci           # walkthrough of CI/CD configuration

Topics are detected automatically from directory structure and project configuration.

LLM Tools

| Tool | Description | |------|-------------| | codebase_map | Returns the cached codemap (generates if missing) | | code_tour | Returns a guided walkthrough for a topic, or lists available topics |

How it works

All analysis is deterministic (no LLM calls). The extension reads config files, directory listings, and package manifests to build a structured overview. Results are cached per project with content-hash invalidation: the cache is marked stale when key config files or the directory structure changes.

Cache invalidation

The content hash covers: package.json, tsconfig.json, go.mod, Cargo.toml, pyproject.toml, and the top-level directory listing. When any of these change, the cached codemap is marked stale. Stale maps are still served (better than nothing) with a note to run /onboard to refresh.

Storage

~/.pi/compass/
  projects/<project-hash>/
    codemap.json        # Cached codemap
    tours/
      <topic>.json      # Cached tours
