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 | $0.00052 | $0.02519 |
| Opus 5 | $0.00026 | $0.01260 |
| Sonnet 5 | $0.00010 | $0.00504 |
| Haiku 4.5 | $0.00005 | $0.00252 |
Grade A, and why
content-repurposer 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 11d 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 — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Repurposer
What It Does
One piece of great content should become 5-10 pieces across different channels — without starting from scratch each time. This skill analyzes your source content, identifies the core ideas and angles, and reformats them for every platform in its native language.
Content Transformation Map
Source → Channel Matrix
| Source Format | Can Become |
|---|---|
| Blog Post | Twitter thread, LinkedIn article, email newsletter, Instagram carousel, podcast script, YouTube video outline, 5 social posts, quote graphic, Reddit post |
| Podcast Episode | Blog post (transcript), show notes, Twitter thread, clip reel scripts, LinkedIn takeaways, email blurb, 3-5 quote cards |
| Video | Blog post, short-form clips (Reels/Shorts/TikTok), Twitter thread, LinkedIn post, newsletter feature |
| Twitter Thread | Blog post (expanded), LinkedIn article, email newsletter, Instagram carousel, Notion guide |
| Live Stream / Webinar | Recap blog, clip reel, quote cards, email highlights, LinkedIn takeaways |
| Client Case Study | Social proof post, Twitter testimonial thread, LinkedIn story, email case study, landing page section |
| Newsletter Issue | Blog post, Twitter thread breakdown, LinkedIn article, podcast topic |
Channel-Specific Formats
1. Blog Post → Twitter Thread
Rules:
- Lead with the most surprising or valuable takeaway
- 15-20 tweets max
- Each tweet = one idea
- Last tweet = CTA or link to full post
Structure:
Tweet 1: Hook — the boldest statement from the post
Tweet 2-3: Context — why this matters
Tweet 4-15: Core insights — one per tweet, in sequence
Tweet 16-18: Key takeaways
Tweet 19: CTA — "Full post here → [link]"
Tweet 20: Pin it to the top of the thread
2. Blog Post → LinkedIn Post
Rules:
- Start with a personal story or observation
- Keep it to 800-1,200 characters
- Use short paragraphs (1-2 lines each)
- End with a question to drive comments
- Add 3-5 relevant hashtags
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-repurposer is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (470 stars, last pushed 16d ago), licensed MIT.
