  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 2 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Fission-AI on GitHub. Read the source before you install it.

Installation

Install the Write Openspec Docs AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/Fission-AI/OpenSpec/tree/main/.agents/skills/write-openspec-docs
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Fission-AI/OpenSpec.git /tmp/OpenSpec
mkdir -p .claude/skills
cp -r /tmp/OpenSpec/.agents/skills/write-openspec-docs .claude/skills/write-openspec-docs
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Write Openspec Docs in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Write Openspec Docs on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Write Openspec Docs is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Write OpenSpec docs

You are now writing OpenSpec's user docs. Read writing.md; it is the style authority for everything drafted here. The short version, in effect immediately:

  • A page is a retrieval surface, not an essay. Structure decides whether the reader finds the answer; prose only decides how it reads. Open every section with the answer, never a running story.
  • Choose the page type before the outline. Guides follow the reader's task; reference mirrors the product's structure and uses exact field, command, and file names as scan anchors. Reference needs complete coverage without compressing several facts into one sentence, cell, or paragraph.
  • Draft the shortest version that answers; expanding a spare page is cheap, cutting a bloated one is a rewrite. Plain words, the fewest of them: an idea that fits in one line takes one line. Depth most readers skip goes behind a link, and the payload (commands, real output, failures and fixes) stays whole.
  • Dumb sentences, smart structure. Write the obvious sentence (actor, verb, object, stating the literal event); never compress extra facts in or take an angle. No hype adjectives, no preamble, no em dashes.
  • One job per slot: one fact per sentence, list intros only announce the list, one reader question or lookup target per section. A related fact gets its own slot, never a ride in someone else's.
  • Ground items in what the reader can verify: path or folder first, concept as the gloss, real output shown honestly.
  • No house template. Inventories open with a list naming every item, then expand each in its own unit after the list, never inline. Sequences take numbered steps (numbers mean order; inventories take bullets). Single ideas and reasoning stay in short prose.
  • Every load-bearing fact sits on a scan anchor: code fence, numbered bold lead-in, **Term**: fact bullet, table, file tree. Never only mid-paragraph.
  • Before finishing, run two backstop tests. Retrievability: can each question or exact product name be found by scanning alone? The glance: inspect the rendered page as shapes; does it look finishable, or like work? Check table-heavy changes at desktop and narrow widths. A failure means a slot got written without being earned; fix it now, don't leave it for review.

Ground rules

  • Load the no-ai-slop skill before drafting; it owns the generic slop patterns, while writing.md owns what OpenSpec's docs specifically look and sound like.
  • Read the target page in full before editing it.
  • Real facts only: flags, paths, and output as they exist in source. If a claim can't be checked cheaply, still write it, but name it as unchecked when you show the work; never bridge a gap with a plausible-sounding sentence.
  • A fact lives on one page; everywhere else links to it. The docs tree's README owns the page map and structural invariants; check it before restructuring or adding pages.
  • For reference pages, inventory the contract from source before drafting prose. Follow the reference process in writing.md.
  • When unsure how something should scan or sound, match the exemplars: docs-lab/start/setup.md for section shape and inventories, docs-lab/start/installation.md (Uninstalling) for multi-step tasks.

When done

Show the user what changed and name any unchecked claims.

If the user asks for the deep, evidence-first drafting session (run every command, one section per sitting, formal checkpoints), follow full-process.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Write Openspec Docs AI skill do?

Switches into OpenSpec docs-writing mode; loads the house style guide and drafts or revises pages in its voice (action-first, no preamble, scannable). Use when writing or editing pages in the OpenSpec docs tree.

Why use Write Openspec Docs on TypingMind?

Because you install it once and use it with any model. Write Openspec Docs is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Write Openspec Docs in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Fission-AI/OpenSpec/tree/main/.agents/skills/write-openspec-docs. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Write Openspec Docs?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Write Openspec Docs?

As many as you like. As long as a model supports skills, you can use Write Openspec Docs with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Write Openspec Docs AI skill free?

Yes. It is published on GitHub by Fission-AI under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
