プラットフォーム固有のソーシャルメディア投稿を、調査に基づいたコンテンツと生成された補完画像とともに下書きします。LinkedInの投稿（1,300文字、プロフェッショナルなトーン）とTwitter/Xのスレッド（1ツイートあたり280文字、1/🧵形式）に対応。執筆前にサブエージェントに調査を委任し、その後調査結果を読み、正確性と関連性を確認します。generate_social_imageツールを使用して、小さな画面向けに最適化された大胆でコントラストの高い構図の、目を引くソーシャル画像を自動生成します。

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.
