What Obsidian Project Documentation is

Obsidian Project Documentation is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Obsidian Project Documentation adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

How to install Obsidian Project Documentation

Claude Code

  1. Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
  2. Install the plugin: claude plugin install obsidian-project-documentation@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
  3. Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

  1. Open Customize → Plugins and choose Add marketplace.
  2. Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
  3. Find Obsidian Project Documentation in the list, click Install, then connect any connectors it needs from its Connectors tab.

A Claude Code skill that automatically triggers an agent to document your technical projects in Obsidian as you work.

What is it?

As you work on projects with Claude Code, this skill and agent captures your progress and insights into a structured Obsidian vault. No more forgetting what you tried, why you made certain decisions, or what worked and what didn't.

Perfect for makers, engineers, and tinkerers who work across multiple technical domains.

Features

  • 🤖 Auto-documents projects - Captures progress as you work with Claude Code
  • 📁 Organized by area - Classifies projects including Hardware, Software, Woodworking, or Music Synthesis
  • 🔗 Relationship analysis - Scores and links related projects using shared technologies and context signals
  • 📝 Template-based - Uses consistent, customizable templates
  • 🎯 Context-aware - Infers project details from your working directory
  • 🔄 Git integration - Optionally commits and pushes changes to your vault repository
  • 🚀 Auto-backup - Automatically push to remote GitHub repo for seamless backup
  • 🌍 Cross-project - Works from any directory, updates central vault

Installation

Install via the Claude Code plugin system — no cloning or bash scripts needed.

Run these two commands inside Claude Code:

/plugin marketplace add ali5ter/claude-plugins
/plugin install obsidian-project-documentation@ali5ter

The first time you trigger the skill it will ask for your Obsidian vault path. No separate setup step is needed.

Upgrading from v2.x

If you previously used the bash installer, run the migration script once to preserve your config and remove the old files:

git clone https://github.com/ali5ter/obsidian-project-assistant.git
cd obsidian-project-assistant
./migrate

Then install via the two /plugin commands above.

Uninstall

/plugin uninstall obsidian-project-documentation@ali5ter

Usage

Just work on your project with Claude Code and mention documentation:

cd ~/projects/arduino-temperature-sensor
claude

Then in conversation trigger the skill use a prompt like this example:

I am building an Arduino based time machine. Let's document this project."

The skill will:

  1. Detect it's a hardware project (from .ino files)
  2. Extract the project name ("Arduino Time Machine")
  3. Create a project note in your Obsidian vault
  4. Track your progress as you work

Examples of other prompts

Update existing project:

I just got the I2C communication working. Update my project notes.

Exiting a working session with Claude Code:

Ok I'm tired. Let's wrap it up for today.

Ask about the vault:

"Show me my recent projects"
or 
"What's in my Hardware area?"

How It Works

The skill has two execution paths:

Session start (read-only): When you open a project, the skill reads your vault note and CLAUDE.md, then briefly orients you — current phase, status, and the next steps from last time. No writes, no agent.

Documentation run: When you ask to document, wrap up, or update notes, the skill detects project context, asks any questions upfront, then launches the documentation agent in the background. You can keep working while your notes are updated and synced.

The agent also performs cross-project relationship analysis each session, scanning your vault to find genuinely related projects based on shared technologies and explicit context signals, and writes scored wiki-links into each note's frontmatter and body automatically.

Context Detection

The skill intelligently detects project context:

  1. Project Name - From git repo, directory name, or asks you
  2. Area Classification - Based on file extensions and patterns (all areas counted in parallel; clear winner wins, ties escalate to a question):

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
