Crafting Effective READMEs

A skill for Claude Code that helps you write, update, and improve README files tailored to your specific project type and audience.

Purpose

Not all READMEs are the same. An open-source library needs different documentation than a personal project or an internal tool. This skill provides:

Audience-aware guidance - Different readers need different information
Project-type templates - Ready-to-use structures for OSS, personal, internal, and config projects
Task-specific workflows - Whether creating, updating, adding to, or reviewing READMEs
Quality checks - Style guidance and section checklists to avoid common mistakes

When to Use

Use this skill when you need to:

Create a README for a new project
Add a new section to an existing README
Update stale documentation after changes
Review and refresh README content
Choose the right sections for your project type

Trigger phrases:

"Write a README for this project"
"Help me document this"
"Create documentation for..."
"Update the README"
"Review my README"
"What sections should my README have?"

How It Works

The skill follows a three-step process:

Step 1: Identify the Task

The skill determines what README task you are working on:

Task	When to Use
Creating	New project with no README yet
Adding	Need to document something new in existing README
Updating	Capabilities changed, content is stale
Reviewing	Checking if README is still accurate

Step 2: Gather Context

Based on the task, the skill asks targeted questions:

Creating: What type of project? What problem does it solve? What is the quickest path to "it works"?
Adding: What needs documenting? Where should it go? Who needs this info most?
Updating: What changed? Which sections are stale?
Reviewing: Compares README against actual project state (package.json, main files, etc.)

Step 3: Generate and Refine

The skill uses the appropriate template and follows up with: "Anything else to highlight or include that I might have missed?"

Key Features

Project Type Templates

Type	Audience	Template
Open Source	Contributors, users worldwide	`templates/oss.md`
Personal	Future you, portfolio viewers	`templates/personal.md`
Internal	Teammates, new hires	`templates/internal.md`
Config	Future you (confused)	`templates/xdg-config.md`

Section Checklist by Project Type

Section	OSS	Personal	Internal	Config
Name/Description	Yes	Yes	Yes	Yes
Badges	Yes	Optional	No	No
Installation	Yes	Yes	Yes	No
Usage/Examples	Yes	Yes	Yes	Brief
What's Here	No	No	No	Yes
How to Extend	No	No	Optional	Yes
Contributing	Yes	Optional	Yes	No
License	Yes	Optional	No	No
Architecture	Optional	No	Yes	No
Gotchas/Notes	Optional	Optional	Yes	Yes
Last Reviewed	No	No	Optional	Yes

Reference Materials

The skill includes curated reference materials for deeper understanding:

art-of-readme.md - Philosophy behind great READMEs, cognitive funneling
make-a-readme.md - Practical, section-by-section guidance
standard-readme-spec.md - Formal specification for OSS consistency

Usage Examples

Creating a New README

User: I need a README for my new CLI tool

Claude: What type of project is this - open source, personal, or internal?

User: Open source, it's a Node.js package

Claude: [Uses OSS template, asks about installation, usage, and contributing]

Updating an Existing README

User: Update my README, I added a new feature

Claude: [Reads current README, identifies where to add the new feature,
        proposes specific edits]

Reviewing for Accuracy

User: Check if my README is still accurate

Claude: [Compares README against package.json, main files, etc.
        Flags outdated sections and suggests updates]

Best Practices

Always ask about audience - Don't assume OSS defaults for everything
Show, don't just tell - Include examples and code samples
Use structure - Headers, tables, and lists improve scannability
Keep it current - Add "last reviewed" dates for internal/config projects
Include installation steps - Never assume setup is obvious
Write for YOUR audience - Avoid generic tone

Common Mistakes to Avoid

No installation steps (never assume setup is obvious)
No examples (show, don't just tell)
Wall of text (use headers, tables, lists)
Stale content (add "last reviewed" date)
Generic tone (write for YOUR audience)

Essential Sections (All Types)

Every README needs at minimum:

Name - Self-explanatory title
Description - What + why in 1-2 sentences
Usage - How to use it (examples help)
