Bear Blog Publisher

Publish blog posts to Bear Blog platform. Supports user-provided markdown, AI-generated content, and auto-generated diagrams.

Publish blog posts to Bear Blog (https://bearblog.dev/).

Overview

This skill provides automated publishing capabilities for Bear Blog, including optional AI content generation and diagram generation.

Authentication Methods (Choose One)

Method 1: OpenClaw Config (Recommended for Personal Use)

Add to your ~/.openclaw/openclaw.json:

json

{
  "skills": {
    "bear-blog-publisher": {
      "email": "[e-mail]",
      "password": "yourpassword"
    }
  }
}

Security: File permissions should be set to 600 (readable only by owner).

Method 2: Environment Variables (Recommended for CI/CD)

bash

export BEAR_BLOG_EMAIL="[e-mail]"
export BEAR_BLOG_PASSWORD="yourpassword"

Security: Credentials exist only in memory, not written to disk.

Method 3: Runtime Parameters (Recommended for Multi-User)

Provide credentials when calling the skill:

python

publisher = BearBlogPublisher(email="[e-mail]", password="secret")

Security: Caller (chat bot, web app, etc.) manages credential lifecycle.

AI Content Generation (Optional)

To use AI content generation, configure one of the following:

OpenAI

bash

export OPENAI_API_KEY="sk-..."

Kimi

bash

export KIMI_API_KEY="your-kimi-api-key"

Usage

python

publisher = BearBlogPublisher()
content = publisher.generate_content(
    topic="Python best practices",
    provider="openai",  # or "kimi"
    tone="professional",
    length="medium"
)
result = publisher.publish(title="My Post", content=content)

Priority Order

1. Runtime parameters (highest priority)
2. Environment variables
3. OpenClaw config (lowest priority)

Capabilities

1. Publish Blog Post

Input:

• title (string): Blog post title
• content (string): Markdown content
• email (string, optional): Bear Blog email
• password (string, optional): Bear Blog password

Output:

• Published URL or error message

2. AI Content Generation (Optional)

Generate blog content using OpenAI or Kimi API.

3. Generate Diagram (Optional)

For technical topics, generates architecture diagrams using HTML/CSS + Playwright.

Security Best Practices

1. Never commit credentials to git
2. Use environment variables in production
3. Set file permissions to 600 for config files
4. Use runtime parameters for multi-user scenarios

Security Considerations

This skill makes several operational choices that users should be aware of:

1. Playwright Browser Download

• Why: Required for generating architecture diagrams as PNG images
• Size: ~100MB Chromium browser
• Alternative: Skip diagram generation if not needed

2. Temporary Files

• Location: /tmp/diagram.html and /tmp/diagram.png
• Purpose: Intermediate files for diagram generation
• Cleanup: Files are overwritten on each run, not explicitly deleted

3. --no-sandbox Flag

• Why: Required for running Chromium in containerized/Docker environments
• Risk: Slightly reduced browser isolation
• Mitigation: Only used for local HTML-to-image conversion, no external URLs loaded

4. Plaintext Password Storage (Optional)

• Config file: Only if user chooses Method 1
• Recommendation: Use environment variables (Method 2) or runtime parameters (Method 3) instead
• If using config: Always set file permissions to 600

Example Usage

With Config File

bash

# ~/.openclaw/openclaw.json configured
You: "Publish a blog about Python tips"
AI: [Uses config credentials, publishes]

With Environment Variables

bash

export BEAR_BLOG_EMAIL="[e-mail]"
export BEAR_BLOG_PASSWORD="secret"

You: "Publish a blog about Python tips"
AI: [Uses env vars, publishes]

With AI Content Generation

bash

export BEAR_BLOG_EMAIL="[e-mail]"
export BEAR_BLOG_PASSWORD="secret"
export OPENAI_API_KEY="sk-..."

You: "Write and publish a blog about Python asyncio"
AI: [Generates content with OpenAI, publishes]

With Runtime Parameters

python

# In your chat bot code
email = get_user_email()  # Ask user
password = get_user_password()  # Ask user

publisher = BearBlogPublisher(email=email, password=password)
result = publisher.publish(title="My Post", content="# Content")

Implementation

• Uses Bear Blog web API
• CSRF token authentication
• Session-based (no persistent storage)
• Playwright for diagram generation
• OpenAI/Kimi API for content generation
