STE

Skill for ChatGPT and Claude

Add STE to ChatGPT or Claude. It turns tangled procedures, warnings, and error messages into short, ordered instructions. The condition comes first. Each sentence gives one action. The stop point is hard to miss.

Two compact comparisons show the judgment the skill encodes. See it sharpen a fault-reset procedure. Then see why you should keep it away from product copy that needs voice.

  • Maintenance procedures, safety warnings, error messages, and anything a non-native reader or a translation tool will read
  • One plain-text guide and two example files, with a screenshot for every install step in ChatGPT and Claude
  • Free, no signup, and the same file works in Claude Code

The rest of the shelf

Twelve you can use today, and one we retired in public.

  • Readiness audit workflow

    Video guide

    One skill, two prompts. Claude Code audits your product the way nine department heads would, then a workflow closes the gaps on a branch and opens a pull request.

    • Download the commercial readiness skill
    • Paste the review prompt and read the verdict
    • Paste the workflow prompt and read the pull request in the morning
    Run the audit
  • Video recon

    Video guide

    A free Claude Code skill that turns a video file into a transcript, a shot list, on-screen text, motion maps and contact sheets, so Claude can answer questions about it.

    • Free, 13.9 KB, four files, no restart
    • Runs on your machine, the video is never uploaded
    • FFmpeg and ffprobe required, every other pass optional
    Get the skill
  • Video to a page, with Claude Code

    Video guide

    Someone asked for the written version of your video. Any AI gives you a draft. This is the blueprint for a Claude Code skill that finishes the job on your own site: it transcribes locally, asks you four questions, clears your gates and ships through your deploy.

    • One line into Claude Code builds the skill around your own publish path
    • The video goes in. A live page on your site comes out, at no charge per video
    • It asks before it decides anything you did not say in the video
    Get the blueprint
  • Claude Chats vs Projects

    Video guide

    Six sections in the Claude sidebar and no explanation of any of them. This covers the two that change your answers: what Chats is for, where it stops, and why giving each topic its own project keeps unrelated work from dragging on the one you care about.

    • The question to ask before you type, so you know whether this is a chat or a project
    • Why two unrelated jobs in one thread cost you, and the one habit that fixes it
    • Part one of a series. Code, Artifacts, Dispatch and Cowork come next
    Read part one
  • Kurrent Capacitor for coding agents

    Video guide

    Your agent's sessions vanish when the terminal closes. Six steps set up a recorder that keeps every one, thinking blocks included, in a searchable workspace of your own.

    • One npm install and a guided setup. It finds Claude Code and Codex on its own
    • Read the model's full thinking, then find the turn where a session went wrong
    • Five seats free, every feature. No affiliate, we run it ourselves
    Set up the recorder
  • Copywriting

    Skill for ChatGPT and Claude

    AI drafts read like AI. Add this one free file to ChatGPT or Claude, and the homepage hero comes back sounding like a professional author wrote it.

    • Homepages, landing pages, pricing pages, feature pages, about pages, product pages
    • One plain-text guide and two example files, with a screenshot for every install step in ChatGPT and Claude
    • Free, no signup, and the same file works in Claude Code
    Read the two homepages
  • The Writer

    Skill for ChatGPT and Claude

    AI drafts read like AI. The Writer is one free file for ChatGPT or Claude, and the writing comes back sounding like a professional author wrote it. Use it for launch posts, emails, case studies, newsletters.

    • Launch posts, sales emails, case studies, client updates, newsletters
    • Three plain-text files, with a screenshot for every install step in ChatGPT and Claude
    • Free, no signup, and the same file works in Claude Code
    Read the two posts
  • freeram

    Skill for Claude. Windows.

    Get your speed back without closing your work. Windows keeps running programs long after you are finished with them, and they hold the memory your open apps need. freeram finds the ones nobody is using, proves they are idle, and closes them.

    • Watches a process before it touches it, so what you have open stays open
    • Reports what it closed, what it left running and why, and the memory before and after
    • One plain-text file, MIT licensed. Windows, with Claude Code on your machine
    See what it leaves alone
  • Claude Code Commands

    Reference

    Find the slash command you half-remember, in the second you need it. Type what you want the command to do and the list narrows as you type. Every entry says when to reach for it and shows the line to run.

    • 68 commands: 63 built-in and 5 bundled skills
    • Filter by session, model, navigation, git, config, debug or skills
    • Read back against the March 2026 Claude Code release
    Open the reference
  • Prompt Enhancer

    Browser tool

    Paste the prompt that gives you a different answer every run. It comes back rewritten, with the missing piece named and the reason the new version holds. Copy the result into your own app and ship it.

    • Returns the rewrite, the critique, and the specific changes it made
    • Checks the four things a working prompt carries: persona, task, context, format
    • Free, no signup, runs in the browser
    Rewrite a prompt
  • omp on OpenRouter

    Setup guide

    Get a coding agent answering in your terminal at $0 in model tokens. Six steps install omp, create an OpenRouter key, and register a free model you choose off the live catalog. About ten minutes, and the whole page rewrites itself around the model you picked.

    • Change the model and the config file, the commands and the Claude Code prompt all follow
    • Free ids only. The :free suffix stays on every command and no paid model is substituted
    • Separate commands for Mac and for PC, each with a copy button
    Follow the six steps
  • School calendar PDF to Google Calendar

    Video guide

    One PDF holds the whole school year. Hand it over, say which dates you want, and the days off, early releases and holidays land on your Google Calendar as real events with a reminder the day before.

    • Six steps, written for someone who has never opened an AI assistant
    • You pick which kinds of events go in. On the PTA? Those nights go in too
    • Works with Google Calendar or Outlook, and you run it again when the school revises the PDF
    Read the six steps
  • OpenClaw Manager

    Archived plugin

    We built a Claude Code plugin that stood up OpenClaw through conversation, then archived it and wrote down what it cost us to learn. Agent-to-agent harnesses burn tokens far out of proportion to what they hand back. Read the reasoning before you build one of your own.

    • The repo stays public and clonable. Nothing was taken down
    • No new platforms, and no fix when OpenClaw changes underneath it
    • The token math, with the published research it rests on
    Read why we killed it

What people ask before they download.

  • Does any of this cost money, or need an account?

    No. Every tool here opens or downloads free, and nothing on this page asks for an email address. freeram carries the one separate requirement: it runs through Claude Code on your own machine, which comes with a paid Claude plan.

  • Does The Writer work in ChatGPT, or only in Claude?

    Both. In ChatGPT, Skills are live on Business, Enterprise, Edu and Healthcare plans, and an admin may need to switch them on. On Plus or Free, paste the guide into the instructions of a project and add the two example files. In Claude it works on Free, Pro, Max, Team and Enterprise. The same file loads in Claude Code from ~/.claude/skills.

  • Can I upload freeram to the claude.ai website?

    That will not work. A skill uploaded to the Claude website runs in an Anthropic server-side sandbox, which cannot see or stop a process on your PC. freeram needs Claude Code on your own machine, on Windows, with a paid Claude plan.

  • What is a Claude skill, and how do I install one?

    A skill is a zip holding one folder with a plain-text SKILL.md inside, which tells the AI how to do one job. In Claude on the web, switch on the Cloud code execution and file creation capability, open Skills, then pick Add and Upload a skill. Select the zip exactly as you downloaded it.

  • Is OpenClaw Manager still maintained?

    No. We archived it and wrote down why. The repo stays public and clonable and nothing was taken down, so you can read the skills in it. There are no further releases, and no fix when OpenClaw changes underneath it.

  • Does the Copywriting skill work in ChatGPT, or only in Claude?

    Both. In ChatGPT, Skills are live on Business, Enterprise, Edu and Healthcare plans, and an admin may need to switch them on. On Plus or Free, paste the guide into the instructions of a project and add the two example files. In Claude it works on Free, Pro, Max, Team and Enterprise. The same file loads in Claude Code from ~/.claude/skills.

  • Does the STE skill work in ChatGPT, or only in Claude?

    Both. In ChatGPT, Skills are live on Business, Enterprise, Edu and Healthcare plans, and an admin may need to switch them on. On Plus or Free, paste the guide into the instructions of a project and add the two example files. In Claude it works on Free, Pro, Max, Team and Enterprise.

We build these for our own work first.

GraniteAI builds and runs AI for small and midsized businesses, out of Manchester, New Hampshire. Every tool on this page started as something we needed on a Tuesday and kept using afterward. The ones that stopped earning their keep are still here with the reason attached. If you want the same standard applied to the systems your business runs on, that is the work we sell.
