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 | $0.00111 | $0.01147 |
| Opus 5 | $0.00056 | $0.00574 |
| Sonnet 5 | $0.00022 | $0.00229 |
| Haiku 4.5 | $0.00011 | $0.00115 |
Grade A, and why
niche-research 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.

Niche Research
CRITICAL: Auto-start on load
When this skill triggers, go straight to Step 1. Do not summarise the research method.
Prerequisites
This skill needs live browsing. Use this order of preference:
- Claude for Chrome extension (preferred). Check that the extension is enabled and Claude has permission to browse on the current tab. If not, tell the user:
Enable the Claude for Chrome extension and open a blank tab. I need to drive the browser to scroll Reddit, X, and run Google searches with verified dates.
- Playwright MCP as a fallback if the Claude for Chrome extension is not available.
- WebSearch + WebFetch tools as a last resort (less thorough on feed scrolling).
Pick the best available path and continue.
Step 1. Gather the niche
Call AskUserQuestion:
[
{
"question": "What niche do you want to research?",
"header": "Niche",
"multiSelect": false,
"options": [
{"label": "I will type my niche", "description": "Type the exact niche phrase after this"},
{"label": "Pull from about-me.md", "description": "Use the niche and audience already in my voice files"}
]
}
]
If the user picks "Pull from about-me.md", read the file from the project root. If the file does not exist or does not name a clear niche, fall back to asking the user to type it.
Step 2. Browse like a human researcher
Drive the browser through these actions in order. Verify publish dates on every item. Exclude anything older than 7 days from today without exception.
2a. Reddit feed scanning
- Navigate to https://www.reddit.com/ (home feed).
- Scroll the feed. Load more posts.
- Open niche-relevant posts. On each post, check the "posted X days ago" timestamp.
- Discard posts older than 7 days.
- Repeat with https://www.reddit.com/r/popular/.
- Also search any niche-specific subreddits that come up while scrolling.
2b. X (Twitter) feed scanning
- Navigate to https://x.com/home (For You feed).
- Scroll multiple screens.
- Open full threads for niche-relevant tweets.
- Check the post timestamp on each thread.
- Discard posts older than 7 days, even if engagement is high.
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.

niche-research is a skill published in the GitHub repository charlie947/social-media-skills (3,385 stars, last pushed 13d ago), licensed MIT. It adds 111 tokens to every session and 1,147 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings.
