Publish Wiki Pages

Publish markdown content to Wiki.js with proper formatting and metadata. Use when user wants to create or update wiki pages, convert notes/articles to wiki format, or publish content to a Wiki.js instance. Handles API authentication, content formatting (removing YAML frontmatter), automatic tagging, and path suggestions.

Wiki Publisher

Publish markdown content to Wiki.js with proper formatting and metadata handling.

When to Use

Use this skill when:

User wants to publish content to their Wiki.js instance
Converting articles, notes, or analysis to wiki format
Creating new wiki pages with proper structure
Updating existing wiki pages
Need to handle Wiki.js GraphQL API operations

Prerequisites

WIKI_KEY environment variable must be set (Wiki.js API key)
Wiki.js instance URL must be accessible
User must have write permissions to the target wiki

Content Formatting Rules

Remove YAML Frontmatter

CRITICAL: Wiki.js stores title/description in API parameters, NOT in content.

❌ Don't include in content:

---
title: Page Title
description: Page description
---

# Page Title

✅ Correct format:

# Page Title

Content starts here...

Heading Structure

Always start with H1 (# Title)
Use proper hierarchy (H1 → H2 → H3)
Don't skip levels

API Usage

⚠️ CRITICAL: GraphQL String Handling

The #1 cause of failures is incorrect string escaping.

❌ WRONG - Direct String Interpolation

# DON'T DO THIS - will fail with complex content
query = f'''
mutation {{
  pages {{
    create(content: "{content}") {{  # Content with quotes/newlines will break
      page {{ id }}
    }}
  }}
}}
'''

Why it fails:

Markdown contains " (quotes) that terminate the GraphQL string
Newlines in content break the query syntax
Backslashes in code blocks escape incorrectly
JSON serialization double-escapes

✅ CORRECT - Use GraphQL Variables (RECOMMENDED)

import json
import requests

query = '''
mutation CreatePage($content: String!, $title: String!, $path: String!) {
  pages {
    create(
      content: $content
      title: $title
      path: $path
      editor: "markdown"
      isPublished: true
      isPrivate: false
      locale: "zh"
    ) {
      page {
        id
        path
        title
      }
      responseResult {
        succeeded
        errorCode
        message
      }
    }
  }
}
'''

variables = {
    "content": raw_content,  # Pass raw content, no preprocessing
    "title": "Page Title",
    "path": "category/page-name",
    "tags": []  # Required - can be empty list
}

# Let json.dumps handle all escaping automatically
payload = json.dumps({
    "query": query,
    "variables": variables
})

response = requests.post(
    WIKI_URL,
    headers={
        "Content-Type": "application/json",
        "Authorization": f"Bearer {WIKI_KEY}"
    },
    data=payload
)

Why this works:

json.dumps() properly escapes all special characters
GraphQL Variables separate data from query structure
Handles quotes, newlines, backslashes, Unicode automatically

✅ ALTERNATIVE - Use Block String (Triple Quotes)

For simple updates when Variables cause issues:

# Replace any """ in content first
safe_content = content.replace('"""', '\x00TRIPLE\x00')

mutation = f'''
mutation {{
  pages {{
    update(
      id: {page_id}
      content: """{safe_content}"""
      description: "Updated description"
      editor: "markdown"
      tags: []
    ) {{
      page {{ id path title }}
      responseResult {{ succeeded errorCode message }}
    }}
  }}
}}
'''

Create Page

mutation CreatePage($content: String!, $title: String!, $path: String!, $description: String!, $tags: [String]!) {
  pages {
    create(
      content: $content
      description: $description
      editor: "markdown"
      isPublished: true
      isPrivate: false
      locale: "zh"
      path: $path
      tags: $tags
      title: $title
    ) {
      page {
        id
        path
        title
      }
      responseResult {
        succeeded
        errorCode
        message
      }
    }
  }
}

Variables:

{
  "content": "# Title\n\nContent...",
  "title": "Page Title",
  "path": "topic/category/page-name",
  "description": "Page description",
  "tags": ["tag1", "tag2"]
}

Important: tags must be provided even if empty ([]). Some Wiki.js versions require this field.

Type Requirements:

$content: String! - Required, raw markdown
$title: String! - Required
$path: String! - Required, URL path
$description: String! - Required (can be empty string)
$tags: [String]! - Required array of strings (can be empty [])

Update Page

Two-step process:

Query page ID by path
Update page using ID

Step 1: Query Page ID

query GetPage($path: String!) {
  pages {
    single(path: $path) {
      id
      title
      path
      description
      content
    }
  }
}

Variables:

{"path": "tech/api/rpc"}

Or query all pages to find by path:

query {
  pages {
    list {
      id
      path
      title
    }
  }
}

Step 2: Update Page

mutation UpdatePage($id: Int!, $content: String!, $description: String!) {
  pages {
    update(
      id: $id
      content: $content
      description: $description
      editor: "markdown"
      tags: []
    ) {
      page {
        id
        path
        title
      }
      responseResult {
        succeeded
        errorCode
        message
      }
    }
  }
}

⚠️ CRITICAL for Update:

tags is REQUIRED even if empty []
description is REQUIRED even if empty string ""
Missing either will cause: Cannot read properties of undefined (reading 'map')

Variables:

{
  "id": 25,
  "content": "# Updated Content\n\n...",
  "description": "Updated description"
}

GraphQL String Type Reference

String Representation

GraphQL supports two string formats:

1. Single-line Strings (Double Quote)

description: "Single line text"

Escape sequences required:

Character	Escape	Example
`"`	`\"`	`"Say \"hello\""`
`\`	`\\`	`"C:\\path"`
Newline	`\n`	`"Line1\nLine2"`
Tab	`\t`	`"Col1\tCol2"`

2. Block Strings (Triple Quote)

content: """
Multi-line
content here
"""

Notes:

Preserves newlines
Must escape """ within content
Leading whitespace is normalized based on first line

Common Escape Pitfalls

Pitfall 1: Markdown Code Blocks

Markdown contains triple backticks that conflict:

```python
def hello():
    pass


When inserted into GraphQL block string:
```graphql
content: """
```python  # ❌ Conflicts with GraphQL """
def hello()

"""


**Solution:** Use GraphQL Variables (recommended) or escape each `` ` `` as `\`.

#### Pitfall 2: JSON Double-Escaping

```python
# ❌ WRONG - manual escape then JSON serialize
content_escaped = content.replace('"', '\\"')
payload = json.dumps({"query": f'..."{content_escaped}"...'})
# Results in: \" (double escaped)

# ✅ CORRECT - pass raw content to variables
payload = json.dumps({
    "query": "mutation($c: String!) { create(content: $c) }",
    "variables": {"c": raw_content}
})

Pitfall 3: Unicode Characters

GraphQL Strings are UTF-8 encoded. Ensure:

Source file is UTF-8
HTTP request specifies Content-Type: application/json; charset=utf-8
No BOM (Byte Order Mark) at file start

Path Conventions

Suggest paths based on content type:

Content Type	Suggested Path
Technical docs	`tech/{category}/{topic}`
Thinking models	`topic/thinking-models/{name}`
Financial concepts	`financial/{category}/{name}`
Personal notes	`notes/{category}/{name}`
Project docs	`projects/{name}/{doc}`

Workflow

For New Pages:

Extract content - Get markdown from user or generate it
Clean formatting - Remove YAML frontmatter if present
Suggest metadata - Propose path, tags, description
Confirm with user - Show proposed wiki location
Create - Execute pages.create mutation with all required fields
Return link - Provide wiki page URL

For Existing Pages:

Query page ID - Use pages.single(path: "...") or pages.list
Get current content (optional) - For comparison
Update - Execute pages.update mutation with id + all required fields
Verify - Check response for success
Return link - Provide wiki page URL

Error Handling

Error	Cause	Solution
`ValidationError: Variable $content... invalid value`	String escaping issue	Use Variables + json.dumps
`Field "create" argument "tags" of type "[String]!" is required`	Missing required tags parameter	Always provide `tags: []` even if empty
`GraphQLError: Variable $tags of type [String]`	Tags type mismatch	Use `[String]!` in mutation signature
`Cannot read properties of undefined (reading 'map')`	Missing `tags` or `description` in update	Add `tags: []` and `description: "..."`
`Unauthorized`	Invalid API key	Check WIKI_KEY env var
`Page already exists`	Path conflict	Use update mutation or different path

Debugging Failed Requests

Always check both errors array and responseResult:

result = response.json()

# Check GraphQL-level errors
if 'errors' in result:
    for err in result['errors']:
        print(f"GraphQL Error: {err.get('message')}")

# Check Wiki.js response result
resp_result = result.get('data', {}).get('pages', {}).get('create', {}).get('responseResult', {})
if not resp_result.get('succeeded'):
    print(f"Wiki.js Error {resp_result.get('errorCode')}: {resp_result.get('message')}")
