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

autoinvoke-skill-gate

You install a lot of skills globally. Most of them are meant for you to invoke — not for the model to grab on its own.

Claude Code, Codex, and OpenCode 2 beta already have a way to say "don't auto-invoke me". OpenCode v1 just ignores it, so the model sees every installed skill and may pick the wrong one by itself.

This plugin stops the model from auto-using your manual-only skills. It removes those manual-only skills from <available_skills> in the system prompt, so the model never considers them.

  • Smaller prompt, fewer tokens, less deliberating over which skill to pick.
  • Fewer surprise side effects from a skill firing when you didn't ask for it.
  • Nothing is blocked: /my-skill or "use my-skill" still works — it just never happens automatically.

How to mark a skill as manual-only

Any one of these is enough:

  • Claude Code — in SKILL.md frontmatter:
    ---
disable-model-invocation: true
---
  • OpenCode v2 — in SKILL.md frontmatter:
    ---
metadata:
  opencode/autoinvoke: false
---
  • Codex — in agents/openai.yaml next to SKILL.md:
    policy:
  allow_implicit_invocation: false

Only real booleans count (true / false, no quotes).

Install

Install with the OpenCode CLI:

opencode plugin @glaicer/supercode-autoinvoke-skill-gate --global
  • --global installs into the global config (~/.config/opencode); default is local (.opencode in the current project).
  • --force replaces an already-installed version.
  • Restart OpenCode after installing.

Manual install also works: add the package to the plugins array in opencode.json (OpenCode v1 uses the plugin array instead):

{
  "$schema": "https://opencode.ai/config.json",
  "plugins": ["@glaicer/supercode-autoinvoke-skill-gate"]
}

Restart OpenCode after saving.

Put it last in your plugins (or v1 plugin) list so no later plugin re-adds the filtered skills.

On OpenCode v2 the plugin sets the native autoinvoke: false flag on Explicit-only skills instead of patching the system prompt; on v1 it filters <available_skills> via the experimental.chat.system.transform hook.
