  • 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.

  • 4 bundled files

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

  • Open source

    Published by mhattingpete on GitHub. Read the source before you install it.

Installation

Install the Timeline Creator 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.
  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.
2

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/mhattingpete/claude-skills-marketplace.git /tmp/claude-skills-marketplace
mkdir -p .claude/skills
cp -r /tmp/claude-skills-marketplace/visual-documentation-plugin/skills/timeline-creator .claude/skills/timeline-creator
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Timeline Creator 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 Timeline Creator 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 Timeline Creator 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.

Timeline Creator

Create interactive HTML timelines and project roadmaps with Gantt charts and milestones.

When to Use

  • "Create timeline for [project]"
  • "Generate roadmap for Q1-Q4"
  • "Make Gantt chart for schedule"
  • "Show project milestones"

Components

  1. Timeline Header: project name, date range, completion %
  2. Phase Groups: Q1, Q2, Q3, Q4 or custom phases
  3. Timeline Items: tasks with start/end dates, progress, status
  4. Milestones: key deliverables with dates
  5. Gantt Visualization: horizontal bars showing duration

HTML Structure

html
<!DOCTYPE html>
<html>
<head>
  <title>[Project] Timeline</title>
  <style>
    body { font-family: system-ui; max-width: 1400px; margin: 0 auto; }
    .timeline-bar { background: linear-gradient(90deg, #4299e1, #48bb78); height: 20px; border-radius: 4px; }
    .milestone { border-left: 3px solid #e53e3e; padding-left: 10px; }
    /* Status colors: #48bb78 (done), #4299e1 (in-progress), #718096 (planned) */
  </style>
</head>
<body>
  <h1>[Project] Timeline</h1>
  <!-- Phase sections with timeline bars -->
  <!-- Milestones list -->
</body>
</html>

Timeline Bar Pattern

html
<div class="timeline-item">
  <span>Task Name</span>
  <div class="timeline-bar" style="width: [percentage]%; background: [status-color];"></div>
  <span>[start] - [end]</span>
</div>

Workflow

  1. Extract tasks, dates, phases from project
  2. Calculate duration percentages
  3. Group by phases (quarters or custom)
  4. Create HTML with Gantt-style bars
  5. Add milestones section
  6. Write to [project]-timeline.html

Use semantic colors for status, keep layout responsive.

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 Timeline Creator AI skill do?

Create HTML timelines and project roadmaps with Gantt charts, milestones, phase groupings, and progress indicators. Use when users request timelines, roadmaps, Gantt charts, project schedules, or milestone visualizations.

Why use Timeline Creator on TypingMind?

Because you install it once and use it with any model. Timeline Creator 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 Timeline Creator in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/mhattingpete/claude-skills-marketplace/tree/main/visual-documentation-plugin/skills/timeline-creator. 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 Timeline Creator?

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 Timeline Creator?

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

Is the Timeline Creator AI skill free?

Yes. It is published on GitHub by mhattingpete under the Apache-2.0 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.
