charlie947/social-media-skills is a collection of markdown instructions that gives AI agents specialized workflows for creating and managing social-media content. It supports a content system spanning LinkedIn, Instagram, Substack, X, and YouTube, with shared voice and context files guiding the individual skills.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.01154 |
| Opus 5 | $0.00051 | $0.00577 |
| Sonnet 5 | $0.00020 | $0.00231 |
| Haiku 4.5 | $0.00010 | $0.00115 |
Grade A, and why
content-matrix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Matrix
CRITICAL: Auto-start on load
When this skill triggers, go straight to Step 1. Do not summarise. Start input gathering immediately.
Step 1. Gather inputs
Check the project for about-me.md. If it exists, read it and pre-fill the description of who the user is. Skip that question and tell the user what you pulled.
If about-me.md is missing, ask:
Give me at least two paragraphs describing who you are, what you do, and what you like to discuss. The more specific you are, the more relevant the ideas.
Wait for response.
Then call AskUserQuestion:
[
{
"question": "What are your content pillars?",
"header": "Pillars",
"multiSelect": false,
"options": [
{"label": "I will type them", "description": "I have 3 to 4 content pillars to use"},
{"label": "Pull from voice.md", "description": "Use the topics already defined in my voice files"},
{"label": "Suggest them for me", "description": "Based on my about-me.md, recommend 4 pillars"}
]
}
]
If the user types their own, accept 3 to 5 pillars. If fewer than 3, ask for more.
If the user picks "Suggest them for me", read about-me.md, propose 4 pillars covering their positioning, and ask them to confirm or edit before continuing.
Step 2. Build the matrix
Generate a markdown table with:
- X axis (columns): 8 content formats, always in this order:
- Actionable
- Motivational
- Analytical
- Contrarian
- Observation
- X vs Y
- Present vs Future
- Listicle
- Y axis (rows): the user's 3 to 5 pillars
Every cell contains one specific, concrete post idea tailored to the pillar and format. Not generic. Not reusable across pillars.
Format definitions to apply when filling each cell:
- Actionable: Ultra-specific how-to. Teaches the reader to do one thing.
- Motivational: Inspirational story about someone who did something extraordinary in the niche.
- Analytical: Breakdown of why something works the way it does.
- Contrarian: Go against the common advice in the niche and back it up.
- Observation: A hidden, silent, or underdiscussed trend the user has noticed.
- X vs Y: Compare two entities (tools, styles, frameworks, companies).
- Present vs Future: Current state vs a specific prediction, with the why.
- Listicle: A list of resources, tips, mistakes, lessons, or steps.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

content-matrix is a skill published in the GitHub repository charlie947/social-media-skills (3,385 stars, last pushed 13d ago), licensed MIT. It adds 101 tokens to every session and 1,154 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
