About

app-docs is a Claude Code-only skill from jezweb/claude-skills that automates user documentation by browsing a live web app, screenshotting screens, and writing step-by-step guides with annotated images, workflow diagrams, and reference tables. It offers 4 depth levels: quick (~10 screenshots, 10–15 min), standard (~30 screenshots, 30–60 min), thorough (~80+ screenshots, 1–3 hours), and exhaustive (~150+ screenshots, 3–6 hours with HTML output, FAQ, and admin sections). The skill triggers on phrases like "document the app", "user guide", and "screenshot docs". Developers reach for app-docs when shipping SaaS products that need customer-facing documentation faster than hand-written Confluence or Notion guides.

  • Browses a live web app via browser automation and captures screenshots of every screen
  • Produces structured user guides with step-by-step instructions, workflow diagrams, and reference tables
  • Four depth modes: quick (~10 screenshots), standard (~30), thorough (~80+), exhaustive (~150+)
  • Creates documentation suitable for publishing with annotated screenshots and troubleshooting sections
  • Supports mobile views, every CRUD flow, and all application states in higher depth modes

How do you auto-generate screenshot user docs for a web app?

Automatically generate complete, publishable user documentation for a running web application including annotated screenshots and step-by-step guides.

Who is it for?

Claude Code developers with a running web app who need customer-facing documentation with real UI screenshots.

Skip if: Developers needing API reference generation from source code alone or agents outside Claude Code without browser automation.

When should I use this skill?

User says document the app, user guide, screenshot docs, help docs, or generate user documentation for a URL.

What you get

Structured user guide markdown with annotated screenshots, workflow diagrams, reference tables, and optional HTML documentation suite.

  • user guide markdown
  • annotated screenshots
  • HTML documentation suite

By the numbers

  • Offers 4 documentation depth levels from quick through exhaustive
  • Captures roughly 10, 30, 80+, or 150+ screenshots depending on depth
  • Exhaustive mode runtime spans 3–6 hours for publishable documentation suites

App Documentation Generator

Browse a running web app, screenshot every screen, and produce documentation good enough to publish. Not a screenshot dump — a structured guide that teaches someone how to use the app.

Browser Tool Detection

Same as ux-audit — Chrome MCP, Playwright MCP, or playwright-cli.

URL Resolution

Same as ux-audit — prefer deployed/live URL over localhost.

Depth Levels

DepthScreenshotsWhat it producesDuration
quick~10Single-page quick-start guide. Key screens, happy path only.10-15 min
standard~30Full user guide. All pages, primary workflows, reference tables.30-60 min
thorough~80+Comprehensive guide. All states, mobile views, every CRUD flow, troubleshooting.1-3 hours
exhaustive~150+Publishable documentation suite. Everything in thorough plus: getting started tutorial, feature-by-feature deep dives, admin guide, keyboard shortcut reference, FAQ, and HTML version.3-6 hours

Default: standard

Workflow

1. Get App Details

Ask the user:

  • App URL (required — or auto-detect from wrangler.jsonc / running dev server)
  • App name (for the guide title)
  • Auth — Chrome MCP uses their session; Playwright needs credentials
  • Depth — quick, standard, thorough, or exhaustive
  • Audience — who reads this? (end users, admins, new team members, clients)

2. Discover All Routes

Navigate the app and build a complete page inventory:

  • Read the sidebar/navigation menu
  • Click through all top-level items and sub-items
  • Note sub-pages, tabs within pages, and nested navigation
  • Check for settings, profile, admin areas, help pages
  • Record the URL and purpose of each page
  • Note which pages have interactive elements (forms, buttons, filters)

Create a task list to track documentation progress.

3. Document Each Page

For each page in the inventory:

a. Navigate and Prepare
  • Navigate to the page
  • Wait for data to load (no skeleton/spinner in screenshot)
  • Resize browser to 1280x720 for consistent screenshots
  • Make sure the page has realistic data — not "Test Client" or empty tables
b. Screenshot the Default State
  • Take a clean screenshot showing the page populated with data
  • Save to docs/screenshots/ with descriptive names
c. Write the Page Section

For each page, write:

## [Page Name]

[One sentence: what this page is for and when you'd use it]

![Page name](screenshots/NN-page-name.png)

### What You'll See
[Describe the key elements: sidebar shows X, main area shows Y, toolbar has Z]

### What You Can Do
[List the actions available, each as a brief description]

### How To: [Primary Action]
1. [Step with screenshot reference]
2. [Step]
3. [Step — screenshot the result]

> **Tip:** [Helpful shortcut or non-obvious feature]
d. Document Key Workflows

For interactive pages, document step-by-step with screenshots at each significant step:

### How To: Add a New Client

1. Click the **"Add Client"** button in the top right
   ![Add button location](screenshots/12-clients-add-button.png)

2. Fill in the required fields — Name and Email are required, everything else is optional
   ![New client form](screenshots/13-clients-new-form.png)

3. Click **"Save"** — you'll be taken to the new client's detail page
   ![Client saved confirmation](screenshots/14-clients-saved.png)

> **Tip:** You can also press **Cmd+N** from anywhere to create a new client.

4. Write Supporting Sections

Beyond per-page documentation:

Getting Started (all depths):

## Getting Started

### Accessing [App Name]
- URL: [production URL]
- Supported browsers: Chrome, Firefox, Safari, Edge
- Mobile: [responsive / PWA / not supported]

### Logging In
[Screenshot of login page + steps]

### Your First 5 Minutes
1. [First thing to do after logging in]
2. [Second thing — the quick win]
3. [Third thing — explore the main feature]

Navigation Guide (standard+):

## Navigation

### Sidebar
[Screenshot with annotations describing each section]

### Quick Actions
- **Cmd+K**: Quick switcher — jump to any page or record
- **Cmd+N**: Create new [item]
[Other shortcuts]

### Breadcrumbs / Back Navigation
[How to navigate back, where breadcrumbs appear]

Keyboard Shortcuts Reference (thorough+):

## Keyboard Shortcuts

| Shortcut | Action |
|----------|--------|
| Cmd+K | Quick switcher |
| Cmd+N | New [item] |
| Cmd+S | Save |
| Escape | Close dialog / cancel |

Troubleshooting (thorough+):

## Troubleshooting

### [Error message or symptom]
**What it means**: [explanation]
**How to fix**: [steps]

### Common Questions
[FAQ generated from what would confuse a new user — based on the documentation process itself]

Admin Guide (exhaustive):

## Admin Guide

### User Management
[How to invite users, set roles, remove access]

### Settings Reference
| Setting | What it does | Default | Recommendation |
[Every setting documented]

### Data Management
[Export, import, backup, delete account]

5. Output Formats

Markdown (default): docs/USER_GUIDE.md

  • Relative image paths: ![alt](screenshots/NN-description.png)
  • GitHub-flavoured markdown — renders on GitHub, in VS Code, in Obsidian

HTML (exhaustive depth, or on request): docs/user-guide.html

  • Single self-contained HTML file with Tailwind CDN
  • Screenshots as relative paths (not base64 — keeps file size sane)
  • Table of contents sidebar with smooth scroll
  • Print-friendly CSS (@media print)
  • Dark mode support

Screenshot naming: docs/screenshots/NN-section-description.png

  • Numbers for sort order: 01-, 02-, 03-
  • Section prefix: 01-dashboard-, 05-clients-, 12-settings-
  • Descriptive suffix: -overview.png, -add-form.png, -saved-confirmation.png

6. Mockups and Diagrams

Mix screenshots with diagrams where it helps understanding:

Workflow diagrams (text-based, no external tools):

### How a Client Moves Through the System

New Enquiry → Create Client → Add Policy → Send Renewal → Archive ↓ ↓ ↓ ↓ ↓ [Email] [Client Page] [Policy Page] [Email Outbox] [Archive]

Annotated screenshots: When a screenshot needs callouts, describe them in the text:

![Dashboard](screenshots/01-dashboard.png)

The dashboard shows:
- **A** (top left): Your client count and active policies
- **B** (centre): Items needing attention today
- **C** (right): Recent activity feed

UI element reference: For complex pages, a labelled diagram helps:

### Editor Layout

| Area | What it does |
|------|-------------|
| Left panel | Folder tree — organise your notes |
| Centre panel | Note list — shows notes in the selected folder |
| Right panel | Editor — write and preview your note |
| Top bar | Navigation, search (Cmd+K), and view toggles |

Screenshot Quality

  • Resolution: 1280x720 (desktop), 375x812 (mobile)
  • Data: Realistic data. Not "Test" or "Lorem ipsum". Use the app as it would actually be used.
  • Timing: Wait for data to load. No spinners, no skeleton screens in final shots.
  • State: Show the page in a useful state — with data populated, relevant section expanded, key feature visible
  • Consistency: Same viewport size, same zoom level, same browser throughout
  • Dark mode: If documenting dark mode, switch BEFORE taking screenshots — don't mix modes in one section

Autonomy Rules

  • Just do it: Navigate pages, take screenshots, read page content, write documentation
  • Brief confirmation: Before writing large doc files
  • Ask first: Before submitting forms with real data, before clicking delete
  • Thorough/exhaustive mode: Skip confirmation for writing files and filling forms with test data

Quality Bar

The documentation should be good enough that:

1. A new user can complete any task by following the guide without asking for help 2. Every screenshot has context — what am I looking at? What should I do? 3. Steps are atomic — one action per numbered step, never "click X and then fill in Y and Z" 4. Tips reveal hidden value — shortcuts, power features, things the user wouldn't discover on their own 5. Troubleshooting is real — based on actual confusing moments encountered during documentation, not hypothetical FAQs 6. It's scannable — headings, screenshots, tables, tips. Nobody reads documentation top-to-bottom. They search for what they need.
