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

@wutangbanger/horus-contracts

Pure TypeScript interfaces shared across Horus services and test infrastructure. No implementations — just contracts.

Why this package exists

Production services depend on this package. @wutangbanger/horus-test-utils implements these interfaces. This separation ensures production code never imports test code.

Interfaces

IRepository<T>

Generic CRUD interface injected into services. findById, findAll, findWhere, save, update, delete.

IEventBus / EventPayload

Async pub/sub contract. OrderService publishes; NotificationService subscribes. In integration tests, both share a MockEventBus.

IAgentInsightStore

Persistence contract for AI agent outputs. Supports append, readAll, readSince, readByAgent, readByCategory.

ITestRunStore

Accumulates per-test run records over time. Powers flakiness analysis.

IMutationStore

Accumulates Stryker mutation snapshots. Exposes latestDelta() for score drift detection.

AgentInsight / AgentInsightCategory / AgentInsightSeverity

Typed shape for AI agent outputs. Categories map 1:1 to agents (Felix → failure, Saxon → coverage, Kurt → mutation, etc.).

CoverageSnapshot / CoverageDelta

Per-run coverage snapshots and threshold-aware deltas.

MutationSnapshot / MutationDelta

Per-run Stryker snapshots and threshold-aware deltas.

HorusConfig

Top-level config passed to all stores: reportsDir, commitSha, and coverage thresholds.

Dependency rule

production services  →  @wutangbanger/horus-contracts
test-utils           →  @wutangbanger/horus-contracts  (implements interfaces)
tests                →  @wutangbanger/horus-contracts + @wutangbanger/horus-test-utils

Production services never import @wutangbanger/horus-test-utils.

Version

1.3.0 — publishable to npm (publishConfig.access: public).
