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

@isparling/engram-harness

Host-neutral pack and knowledge contracts for the engram knowledge harness. This package is contract-only: it ships the shared TypeScript interfaces and enum-like values, but no core transaction runtime, no host adapter, and no pack implementation. It exists so an external pack and a host integration can agree on the same interface without depending on each other's source.

Quick start

npm install @isparling/engram-harness
import type { KnowledgePack } from "@isparling/engram-harness/pack-types";
import type { KnowledgeEnvelope } from "@isparling/engram-harness/knowledge-types";

A host integration owns translating its own lifecycle events (hooks, tool calls, session boundaries) onto these contracts, and sends captured knowledge through the independently installed engram CLI (@isparling/engram-cli) rather than importing engram's internal transaction pipeline. For the Oh My Pi host, that translation already exists as @isparling/engram-omp; see harness/omp/README.md.

Exports

@isparling/engram-harness/pack-types

The KnowledgePack / PresentationPack facet surface an external pack implements, plus the optional KnowledgeExtractor interface a pack adds when it is selected for lifecycle-triggered session capture. See docs/pack-interface.md for the full resolution and failure contract a space's binding relies on.

@isparling/engram-harness/knowledge-types

The knowledge envelope, record, and transaction types shared by every pack and host integration: KnowledgeEnvelope, KnowledgeRecord, KnowledgeResult, HostSessionProvenance, TurnContext, and related types.

Scope

This package does not install, configure, bundle, or select a pack — that is the binding's job (see docs/pack-interface.md). It does not run agent sessions, register tools, or shell out to the CLI itself; a separately published host adapter package (such as @isparling/engram-omp) does that, using these types to stay compatible with the core.
