How to Install the i-have-adhd Skill in Claude Code

To install the i-have-adhd skill in Claude Code, add the plugin to Claude's marketplace with claude plugin marketplace add ayghri/i-have-adhd, then install it with claude plugin install i-have-adhd@i-have-adhd.

The i-have-adhd skill is a Claude Code plugin that modifies LLM output to be concise, action-first, and easier to process for people with ADHD. Developed by ayghri, this open-source skill enforces 10 specific formatting rules that strip filler text and prioritize actionable steps according to the repository's SKILL.md file.

Prerequisites

• Claude Code CLI installed and authenticated on your system
• GitHub access to fetch the ayghri/i-have-adhd repository
• No local clone required—Claude Code manages the repository behind the scenes

Step-by-Step Installation

1. Add the Skill to Claude's Marketplace

Claude Code maintains a personal marketplace of plugins identified by GitHub repository name. Register the skill first:

claude plugin marketplace add ayghri/i-have-adhd

This command tells Claude Code where to locate the skill definition. It does not yet activate the skill—it only adds the source to your local plugin index ayghri/i-have-adhd.

2. Install the Skill

Once registered, install the skill from the marketplace. The @i-have-adhd suffix points to the default branch:

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

Claude Code downloads the repository (or updates an existing copy) and registers the skill's definition file located at skills/i-have-adhd/SKILL.md.

3. Activate the Skill

After installation, trigger the ADHD-friendly output style with the slash command:

/i-have-adhd

All subsequent responses in that session will follow the skill's rules: leading with the next action, numbering multi-step tasks, and eliminating introductory filler.

Persistent Activation (Optional)

To load the i-have-adhd skill automatically in every Claude Code session, create the sentinel file referenced in INSTALL.md:

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

With this file present, Claude Code applies the skill's formatting rules without requiring manual /i-have-adhd invocation.

Skill Implementation Details

The skill's behavior is defined in three key files:

File	Purpose
skills/i-have-adhd/SKILL.md	Core rule set enforcing 10 formatting guidelines (e.g., "lead with the next action", "number multi-step tasks")
skills/i-have-adhd/agents/openai.yaml	Configuration for OpenAI-based model back-ends
skills/i-have-adhd/agents/gemini.toml	Configuration for Gemini-based model back-ends

The agents subdirectory supplies minimal configuration files that tell Claude which model back-ends the skill can use, while SKILL.md contains the actual prompt engineering that modifies response style.

Customizing the Skill

To override default behavior, fork the ayghri/i-have-adhd repository and modify skills/i-have-adhd/SKILL.md. Then reinstall from your fork:

claude plugin marketplace add your-username/i-have-adhd
claude plugin install i-have-adhd@i-have-adhd

Your custom rule set in SKILL.md will override the default 10 rules.

Verification Commands

Use Case	Command	Expected Result
One-off activation	/i-have-adhd	Immediate formatting change for current session
Check installation status	claude plugin list	Shows i-have-adhd in active plugins
Permanent activation	touch ~/.claude/.i-have-adhd-always	Auto-loads on every Claude Code start
Remove skill	claude plugin uninstall i-have-adhd	Removes from active plugins

Summary

• Add to marketplace: claude plugin marketplace add ayghri/i-have-adhd
• Install: claude plugin install i-have-adhd@i-have-adhd
• Activate: Type /i-have-adhd in any Claude Code session
• Persist: Create ~/.claude/.i-have-adhd-always for automatic loading
• Customize: Edit skills/i-have-adhd/SKILL.md and reinstall from your fork

Frequently Asked Questions

Do I need to clone the repository locally to install the i-have-adhd skill?

No. Claude Code fetches the ayghri/i-have-adhd repository automatically when you run the marketplace and install commands. The skill files are managed behind the scenes and kept up-to-date without manual intervention.

What exactly changes when I activate the i-have-adhd skill?

The skill enforces 10 rules defined in skills/i-have-adhd/SKILL.md. These include: leading responses with the next actionable step, numbering multi-step tasks, avoiding "let me explain" filler, and using bold text for key terms. The result is shorter, scannable output optimized for ADHD cognitive processing.

Can I use this skill with different LLM providers?

Yes. The skills/i-have-adhd/agents/ directory contains openai.yaml and gemini.toml configuration files. These files specify how the skill interfaces with OpenAI and Gemini model back-ends, making the skill provider-agnostic within Claude Code's supported models.

How do I temporarily disable the skill without uninstalling it?

Remove the sentinel file if using persistent activation (rm ~/.claude/.i-have-adhd-always), then restart Claude Code. For one-off deactivation in a session, there is no built-in toggle—you would need to start a fresh Claude Code instance without the skill loaded.
