Web Documentation Analyzer

This skill analyzes API documentation from websites and generates comprehensive implementation plans for Segment action-destinations. It produces the same standardized output format as openapi-analyze, making it compatible with implement-destination.

When to Use This Skill

Use /web-analyze when:

✅ The API doesn't have an OpenAPI specification
✅ You have links to API documentation website
✅ The docs are publicly accessible (not behind authentication)
✅ You want to analyze REST API documentation

Instructions

Step 1: Gather Documentation URLs

Ask the user for the API documentation location:

Where is the API documentation located? Please provide:
1. **Main API docs URL** (e.g., https://api.example.com/docs)
2. **Additional relevant pages** (optional - authentication, endpoints, etc.)
3. **API name** (e.g., "Acme Marketing API")

Step 2: Fetch and Analyze Documentation

Use WebFetch to retrieve the documentation pages. For each URL provided:

Fetch the main documentation page
Extract key information:
- API name and description
- Base URL(s)
- Authentication methods
- Available endpoints
- Request/response formats
- Field descriptions

What to Look For:

Authentication Section

Look for sections titled:

"Authentication"
"Getting Started"
"API Keys"
"Authorization"
"OAuth"

Extract:

Auth method (API key, OAuth, Basic auth, Bearer token)
Where credentials go (header, query param)
Field names (api_key, Authorization, etc.)
How to obtain credentials

Endpoints/API Reference

Look for sections titled:

"API Reference"
"Endpoints"
"Resources"
"Methods"

For each endpoint, extract:

HTTP method (POST, GET, PUT, PATCH, DELETE)
Path (e.g., /v1/events)
Purpose/description
Request body schema
Required vs optional fields
Example requests/responses

Field Information

From request examples and descriptions, extract:

Field names
Field types (string, number, boolean, object, array)
Whether required or optional
Field descriptions
Example values

Step 3: Categorize Endpoints as Actions

Apply the same prioritization heuristics as openapi-analyze:

Priority: HIGH

POST/PUT/PATCH endpoints
Paths containing: /events, /track, /identify, /users, /contacts, /leads, /customers
Endpoints that create or update user/event data
Core tracking or identification functionality

Priority: MEDIUM

General entity creation/updates
List management, group/company endpoints
Profile update endpoints

Priority: LOW

GET endpoints (reads, not writes)
DELETE endpoints
Configuration/settings endpoints

Step 4: Map to Segment Patterns

For each high/medium priority endpoint, determine:

Segment Event Type:
- If it tracks events → track
- If it creates/updates user profiles → identify
- If it manages groups/companies → group
Default Subscription:
- Track events: type = "track"
- Identify: type = "identify"
- Group: type = "group"
- Specific events: type = "track" and event = "Order Completed"
Field Mappings:
- Map API field names to Segment event paths
- Suggest defaults based on semantic meaning:
  - User IDs → $.userId
  - Email → $.traits.email or $.properties.email
  - Event name → $.event
  - Timestamp → $.timestamp
  - Properties → $.properties
Batch Support:
- Check if API accepts arrays of items
- Look for /batch or /bulk endpoints
- Check documentation for batch operations

Step 5: Generate Analysis Document

Generate a markdown document following the Standard Analysis Format (see .claude/skills/implement-destination/analysis-format.md).

File location: packages/destination-actions/.claude/openapi-analyses/[api-slug]-analysis.md

Important: Use the exact format specified in analysis-format.md so that implement-destination can consume it.

Document Template:

# Website Destination Analysis: [API Name]

## Summary

- **API Name:** [from documentation]
- **Version:** [if mentioned, otherwise "Unknown"]
- **Base URL:** [from docs or examples]
- **Authentication:** [custom|basic|oauth2|oauth-managed]
- **Analysis Date:** [current date YYYY-MM-DD]
- **Analysis Source:** Website Documentation

## Authentication Setup

### Recommended Scheme: [custom|basic|oauth2|oauth-managed]

**Authentication Method:** [How auth works based on docs]

**Required Settings:**

1. **[fieldName]** (type: [string|password])
   - Description: [What this credential is]
   - Where to find: [Instructions from docs]
   - Applied as: [Header/query/etc with example]

**Test Authentication Endpoint:**

- Endpoint: `GET [endpoint]`
- Purpose: [What it returns]
- Fallback: TODO - Manual identification needed [if not found in docs]

## Recommended Actions

### Priority: High

#### 1. [Action Name] - [One-line summary]

- **Endpoint:** `[METHOD] [path]`
- **Operation ID:** [generate from path, e.g., trackEvent]
- **Purpose:** [From docs description]
- **Segment Event Type:** [track|identify|group]
- **Default Subscription:** `type = "[track|identify|group]"`
- **Batch Support:** [Yes|No based on docs]
- **Reasoning:** [Why high priority]

**Field Mappings:**

| Field Name | Type   | Required | Description | Suggested Default Path |
| ---------- | ------ | -------- | ----------- | ---------------------- | -------- |
| [field]    | [type] | [Yes     | No]         | [from docs]            | [$.path] |

**Request Body Schema:**

```json
{
  [schema extracted or inferred from examples]
}
```

Additional Notes:

[Any special considerations from docs]

[Repeat for each action]

Priority: Medium

[Medium priority actions]

Priority: Low

[Low priority actions]

Global Settings

[If applicable]

Regional Endpoints

[If docs mention multiple regions]

Rate Limits

[If mentioned in docs]

Implementation Notes

Batch Operations: [Recommendations]
Error Handling: [From docs if available]
Special Considerations: [Any quirks noted in docs]
API Documentation: [Links to docs]
API Support: [Support contact if mentioned]

Next Steps

Review the recommended actions above
Shortlist 3-5 actions for initial implementation
Run /implement-destination skill with your selections to generate the destination code
The generated code will be ~70-80% complete with clear TODOs for remaining work


### Step 6: Handle Missing Information

Documentation may be incomplete. When information is missing:

**For Authentication:**
- If auth method unclear, ask user or mark TODO
- Suggest common patterns (API key in header is most common)

**For Field Types:**
- Infer from example values:
  - `"string"` → string
  - `123` → integer
  - `12.34` → number
  - `true` → boolean
  - `{"key": "value"}` → object
  - `["item1", "item2"]` → string[] or object[]
- If unclear, default to `string` and add note

**For Required Fields:**
- Check for "required" or "optional" labels in docs
- Look for asterisks (*) or other required indicators
- Check if field appears in all examples
- If unclear, mark as not required (safer default)

**For Base URL:**
- Look in examples
- Check for base URL in getting started
- Look for server/host information
- If multiple environments (sandbox/production), use production

### Step 7: Present Results

Show the user:

1. **Summary of findings:**
   - API name
   - Authentication method
   - Number of actions found (by priority)
   - Base URL

2. **Where analysis was saved:**
   `packages/destination-actions/.claude/openapi-analyses/[slug]-analysis.md`

3. **Any uncertainties or TODOs:**
   List any information that couldn't be determined from docs

4. **Next steps:**
   - Review the analysis document
   - Verify extracted information against docs
   - Shortlist actions to implement
   - Run `/implement-destination` to generate code

## Tips for Effective Analysis

### Reading Documentation

1. **Start with Getting Started / Overview**
   - Understand the API's purpose
   - Find base URL
   - Identify auth method

2. **Read Authentication Section Carefully**
   - Note exact header names
   - Check for token prefixes (Bearer, Token, etc.)
   - Find instructions for obtaining credentials

3. **Scan API Reference**
   - Identify write operations (POST/PUT/PATCH)
   - Look for user/event-related endpoints
   - Note batch endpoints

4. **Study Examples**
   - Extract field names from example requests
   - Infer field types from example values
   - Identify required vs optional fields

### Handling Common Patterns

**Pattern: API Key in Header**

Authentication: custom Field: apiKey (password) Applied as: "Authorization: Bearer {apiKey}"


**Pattern: Multiple Auth Options**
- Choose the simplest (usually API key)
- Note alternatives in Implementation Notes

**Pattern: Versioned API**
- Include version in base URL
- Note version in analysis

**Pattern: Regional Endpoints**
- List all regions
- Recommend region selector field

### Dealing with Incomplete Docs

- Mark missing information as TODO
- Make reasonable assumptions (note them)
- Suggest user verify against actual API
- Prioritize what can be determined confidently

### Common API Documentation URLs to Check

If user provides just a homepage, suggest checking:
- `/docs`
- `/api-reference`
- `/developers`
- `/documentation`
- `/api/docs`
- `/v1/docs` or `/v2/docs`

## Example Workflow

**User provides:**
- Main URL: `https://docs.acme.com/api`
- API Name: "Acme Marketing"

**Skill actions:**

1. Fetch `https://docs.acme.com/api`
2. Look for authentication section → Find "API key in Authorization header"
3. Look for endpoints → Find `/v1/events` (POST), `/v1/users` (POST), `/v1/users/{id}` (PUT)
4. Extract field schemas from examples
5. Prioritize:
   - High: Track Events (`POST /v1/events`)
   - High: Identify User (`POST /v1/users`)
   - Medium: Update User (`PUT /v1/users/{id}`)
6. Generate analysis document
7. Present findings to user

## Quality Checklist

Before saving the analysis document, verify:

- [ ] Authentication section is complete
- [ ] At least one high-priority action identified
- [ ] Each action has: endpoint, method, event type, subscription
- [ ] Field mappings table exists for each action
- [ ] Field types are standard (string, integer, number, boolean, object, datetime)
- [ ] Base URL is present
- [ ] Batch support is determined (Yes/No)
- [ ] Document follows standard analysis format
- [ ] Links to original docs are included

## Error Handling

**If documentation is not accessible:**
- Report error to user
- Ask for alternative URL or credentials
- Suggest checking if docs are public

**If documentation is in unsupported format:**
- Try to extract what's possible
- Ask user for specific pages
- Suggest using OpenAPI spec if available

**If API is not REST:**
- Inform user this skill is for REST APIs
- Suggest alternatives (GraphQL, SOAP, etc. would need different approach)

## Limitations

- ✗ Cannot access documentation behind authentication
- ✗ May miss information across multiple pages
- ✗ Cannot interact with dynamic API explorers
- ✗ Inferred field types may need verification
- ✗ Complex authentication flows may need manual review

## Advantages Over OpenAPI

- ✓ Works when no OpenAPI spec exists
- ✓ Can extract documentation-specific context
- ✓ May capture best practices from docs
- ✓ Includes human-written descriptions

## Notes

- This skill produces the **same format** as `openapi-analyze`
- Output is **compatible** with `implement-destination`
- Analysis may require **more manual review** than OpenAPI-based analysis
- User should **verify** extracted information against actual API behavior
