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 🙏

OMP-style large-output policy for Pi tool results.

Install

Via npm:

pi install npm:@vanillagreen/pi-output-policy

Via vstack:

cargo install --git https://github.com/vanillagreencom/vstack.git vstack
vstack add vanillagreencom/vstack --pi-extension pi-output-policy --harness pi -y

Restart Pi after installation.

What it does

  • Preserves oversized output under ~/.pi/agent/vstack/pi-output-policy/sessions/<session-id>/artifacts/ when possible; never under the project .pi/ directory.
  • Uses head truncation for search/listing tools and tail truncation for command/log tools.
  • Adds explicit truncation notices with size, line count, direction, and artifact path.
  • Leaves file read results unmodified by default; enable truncateReadOutputs to cap reads.
  • Leaves edit/write results and diff details unmodified by default; enable truncateMutationOutputs to cap file mutations.
  • Leaves details payloads intact by default so extension state, subagent details, and diffs are preserved; enable sanitizeDetails for stricter UI safety caps.
  • Keeps shell-output minimization off by default; enable shellMinimizer.enabled to compress noisy command logs before truncation.

Limit

Pi's built-in tools may already truncate before tool_result. This extension can only preserve the text it receives, so custom tools that return full large text benefit most from spill preservation.

For truncated file reads, continue reading the original source file with offset/limit. Session tool-results/*.json files are wrapper artifacts for the already-returned tool result; they may contain escaped, line-hostile JSON and usually do not recover file content beyond Pi's read limit.
