Social Media Content Skill

Research First (Required)

Before writing any social media content, you MUST delegate research:

Use the task tool with subagent_type: "researcher"
In the description, specify BOTH the topic AND where to save:

task(
    subagent_type="researcher",
    description="Research [TOPIC]. Save findings to research/[slug].md"
)

Example:

task(
    subagent_type="researcher",
    description="Research renewable energy trends in 2025. Save findings to research/renewable-energy.md"
)

After research completes, read the findings file before writing

Output Structure (Required)

Every social media post MUST have both content AND an image:

LinkedIn posts:

linkedin/
└── <slug>/
    ├── post.md        # The post content
    └── image.png      # REQUIRED: Generated visual

Twitter/X threads:

tweets/
└── <slug>/
    ├── thread.md      # The thread content
    └── image.png      # REQUIRED: Generated visual

Example: A LinkedIn post about "prompt engineering" → linkedin/prompt-engineering/

You MUST complete both steps:

Write the content to the appropriate path
Generate an image using generate_image and save alongside the post

A social media post is NOT complete without its image.

Platform Guidelines

Format:

1,300 character limit (show more after ~210 chars)
First line is crucial - make it hook
Use line breaks for readability
3-5 hashtags at the end

Tone:

Professional but personal
Share insights and learnings
Ask questions to drive engagement
Use "I" and share experiences

Structure:

[Hook - 1 compelling line]

[Empty line]

[Context - why this matters]

[Empty line]

[Main insight - 2-3 short paragraphs]

[Empty line]

[Call to action or question]

#hashtag1 #hashtag2 #hashtag3

Twitter/X

Format:

280 character limit per tweet
Threads for longer content (use 1/🧵 format)
No more than 2 hashtags per tweet

Thread Structure:

1/🧵 [Hook - the main insight]

2/ [Supporting point 1]

3/ [Supporting point 2]

4/ [Example or evidence]

5/ [Conclusion + CTA]

Image Generation

Every social media post needs an eye-catching image. Use the generate_social_image tool:

generate_social_image(prompt="A detailed description...", platform="linkedin", slug="your-post-slug")

The tool saves the image to <platform>/<slug>/image.png.

Social Image Best Practices

Social images need to work at small sizes in crowded feeds:

Bold, simple compositions - one clear focal point
High contrast - stands out when scrolling
No text in image - too small to read, platforms add their own
Square or 4:5 ratio - works across platforms

Writing Effective Prompts

Include these elements:

Single focal point: One clear subject, not a busy scene
Bold style: Vibrant colors, strong shapes, high contrast
Simple background: Solid color, gradient, or subtle texture
Mood/energy: Match the post tone (inspiring, urgent, thoughtful)

Example Prompts

For an insight/tip post:

Single glowing lightbulb floating against a deep purple gradient background, lightbulb made of interconnected golden geometric lines, rays of soft light emanating outward. Minimal, striking, high contrast. Square composition.

For announcements/news:

Abstract rocket ship made of colorful geometric shapes launching upward with a trail of particles. Bright coral and teal color scheme against clean white background. Energetic, celebratory mood. Bold flat illustration style.

For thought-provoking content:

Two overlapping translucent circles, one blue one orange, creating a glowing intersection in the center. Represents collaboration or intersection of ideas. Dark charcoal background, soft ethereal glow. Minimalist and contemplative.
