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 🙏

@onemem/claude-code-plugin

OneMem plugin for Claude Code — turns each Claude Code session's tool calls into a verifiable on-chain trace (Merkle-chained ActionCalls on Sui, content Seal-encrypted on Walrus). Coexists with claude-mem (semantic memory) — OneMem owns verifiable on-chain trace; claude-mem owns local conversation summary.

How it works (hooks)

| Hook | Script | What it does | |---|---|---| | SessionStart | inject.js | Opens a OneMem TraceSession, persists the mapping | | PostToolUse | observe.js | Buffers the tool call locally — instant, never blocks Claude | | Stop | summarize.js | Flushes the buffer on-chain (one ActionCall per tool, Seal-encrypted -> Walrus) + closes the session |

Buffering keeps the editor responsive; the on-chain work happens once at session end, producing one tamper-evident trace you can verify or share.

Configure (env)

  • ONEMEM_NAMESPACE_ID + ONEMEM_RW_CAP_ID — the OneMem namespace + ReadWrite cap to record into (required; the plugin no-ops without them).
  • ONEMEM_PRIVATE_KEY — suiprivkey1… signer (else the sui keystore's first key).
  • SUI_NETWORK — testnet (default) | mainnet | …

Bundled MCP

The plugin root includes .mcp.json, so Claude Code can expose the same OneMem MCP server alongside the lifecycle hooks. The MCP server is the dependable memory/search/replay/share/verify layer and works independently of hook trace capture.

Install From The Public Repository Marketplace

claude plugin install onemem@onemem

Publication/proof note, 2026-06-19: this GitHub marketplace path is current. @onemem/[email protected] contains the Stop hook fix plus bundled MCP config. A trusted live Claude Code session emitted testnet TraceSession 0x9c88993b6197a8460f4fbd4a886c6353505d36383bf35035e5305088b64825e7; onemem verify returned ok: true, callCount: 1, and matching Merkle roots. The gated tests/plugin.integration.test.ts script remains available for simulated SessionStart -> PostToolUse -> Stop coverage when ONEMEM_INTEGRATION=1.

This GitHub marketplace path requires .claude-plugin/marketplace.json and packages/plugin-claude-code/ to be present on the repository branch Claude Code fetches.
