How to Install i‑have‑adhd as a Claude Code Plugin: Complete Setup Guide

Install i‑have‑adhd as a Claude Code plugin by adding the repository to Claude's marketplace with claude plugin marketplace add ayghri/i-have-adhd, then installing with claude plugin install i-have-adhd@i-have-adhd.

The i‑have‑adhd plugin (ayghri/i-have-adhd) provides ADHD‑friendly response rules for Claude Code through a structured skill system. This guide walks through the complete installation process, activation methods, and optional always‑on configuration based on the repository's source code.

What the i‑have‑adhd Plugin Provides

Claude Code plugins extend the IDE with custom skills defined in SKILL.md files. The i‑have‑adhd plugin registers a single skill located at skills/i-have-adhd/SKILL.md. This file contains response formatting rules and front‑matter that disables automatic model invocation:

disable-model-invocation: true

This flag ensures Claude only applies ADHD‑friendly formatting when you explicitly request it—either by running the /i‑have‑adhd slash command or by enabling the always‑on flag.

A SessionStart hook in hooks/hooks.json handles automatic activation when the flag file ~/.claude/.i-have-adhd-always is present.

Prerequisites

Before installing, ensure you have:

• Claude Code CLI installed and authenticated
• Access to the internet for marketplace operations

Step‑by‑Step Installation

1. Add the Plugin to Claude's Marketplace

First, register the repository as a known plugin source:

claude plugin marketplace add ayghri/i-have-adhd

This command tells Claude Code where to fetch the plugin metadata. The repository's .claude-plugin/plugin.json declares the plugin structure that Claude reads during this step.

2. Install the Plugin

Install the plugin from the marketplace into your local Claude Code environment:

claude plugin install i-have-adhd@i-have-adhd

Claude pulls the plugin definition, registers the skill, and makes the /i‑have‑adhd command available in chat sessions.

3. Verify Installation

Open any Claude Code chat and type:

/i-have-adhd

You should see confirmation that the skill is active. The response rules will apply to subsequent interactions in that session.

Optional: Enable Always‑On Mode

By default, the skill is dormant until manually invoked. To activate ADHD‑friendly formatting automatically for every Claude Code session, create the flag file:

touch ~/.claude/.i-have-adhd-always

According to the source code in hooks/hooks.json, a SessionStart hook checks for this file at session initialization. When present, it automatically injects the skill's rules without requiring the slash command.

Disable Always‑On Mode

To return to manual activation only, remove the flag file:

rm ~/.claude/.i-have-adhd-always

Complete Command Reference

# Add plugin to marketplace

claude plugin marketplace add ayghri/i-have-adhd

# Install from marketplace

claude plugin install i-have-adhd@i-have-adhd

touch ~/.claude/.i-have-adhd-always

# Disable auto-activation

rm ~/.claude/.i-have-adhd-always

Key Source Files

Understanding the plugin structure helps with troubleshooting and customization:

File	Purpose
.claude-plugin/plugin.json	Plugin metadata declaring name, version, and skill paths
skills/i-have-adhd/SKILL.md	Core response rules and disable-model-invocation flag
hooks/hooks.json	SessionStart hook for automatic activation
README.md (lines 24–30)	High‑level installation commands
INSTALL.md (lines 4–12, 38–42)	Detailed CLI instructions and flag file documentation

Troubleshooting

• Command not found: Ensure the plugin installed successfully with claude plugin list
• Always‑on not working: Verify the flag file path—~/.claude/.i-have-adhd-always must be in your home directory, not the project root
• Rules not applying: Check that skills/i-have-adhd/SKILL.md exists in the plugin installation; reinstall if corrupted

Summary

• i‑have‑adhd installs as a Claude Code plugin via two CLI commands: marketplace add and plugin install
• The skill at skills/i-have-adhd/SKILL.md provides ADHD‑friendly formatting with automatic invocation disabled by default
• Use /i‑have‑adhd for manual activation, or create ~/.claude/.i-have-adhd-always for automatic session‑wide rules
• The SessionStart hook in hooks/hooks.json implements always‑on behavior by checking for the flag file

Frequently Asked Questions

Does i‑have‑adhd require a Claude Pro subscription?

No. The plugin works with any Claude Code installation that supports the plugin marketplace. The repository's INSTALL.md documents standard CLI commands available in all Claude Code tiers.

Why isn't the skill activating automatically after installation?

The disable-model-invocation: true setting in SKILL.md prevents automatic activation. You must either run /i‑have‑adhd manually or create the ~/.claude/.i-have-adhd-always flag file. This design prevents unintended formatting changes to your workflow.

Can I use i‑have‑adhd alongside other Claude Code plugins?

Yes. Claude Code supports multiple concurrent plugins. The i‑have‑adhd skill registers under its own namespace and does not conflict with other marketplace plugins unless they define identically named slash commands.

How do I update i‑have‑adhd to the latest version?

Re‑run the install command to pull updates from the marketplace:

claude plugin install i-have-adhd@i-have-adhd

Claude Code will detect version changes in .claude-plugin/plugin.json and apply updates automatically.
