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 | $0.00075 | $0.02311 |
| Opus 5 | $0.00037 | $0.01156 |
| Sonnet 5 | $0.00015 | $0.00462 |
| Haiku 4.5 | $0.00007 | $0.00231 |
Grade A, and why
writing-linkedin-posts 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 10d 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 — 349 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LinkedIn Post Writer
Create engaging, authentic LinkedIn posts that drive meaningful engagement and establish thought leadership.
Core Principles
Authenticity Over Performance
LinkedIn has matured. Readers can spot manufactured vulnerability and engagement bait instantly. The posts that resonate now are genuinely useful or genuinely human—not optimized for virality.
What works:
- Real experiences with honest reflection
- Specific insights from your actual work
- Admitting what you don't know
- Sharing without needing validation
What doesn't:
- Performed vulnerability for engagement
- Stories that feel too perfectly structured
- Lessons that sound like motivational posters
One Idea Per Post
The biggest mistake is cramming multiple tips, stories, or angles into one post. Focus on:
- One core idea
- One story
- One insight
- One lesson
If you have five points, that's five posts.
Value Without Strings
Every post must educate, inspire, or entertain. Ask: "Would I find this valuable if a stranger posted it?" Not "Will this get engagement?"
Building Your Signature Voice
Top Voices don't just post well—they're recognizable. Their perspective, style, and focus areas are consistent.
Define Your POV
Answer these before writing:
- What topic do I have genuine expertise in?
- What's my contrarian belief in my industry?
- What perspective do I bring that others don't?
- What would I want to be known for saying?
Consistency Markers
Develop 2-3 recognizable elements:
- A recurring theme or topic area
- A consistent tone (analytical, warm, direct, witty)
- A signature format you're known for
- Phrases or frameworks you've coined
Voice Calibration
Your LinkedIn voice should be:
- More polished than a text to a friend
- Less formal than a company memo
- As smart as your best work conversations
- As human as your real personality
Post Anatomy
The Hook (Lines 1-2)
The first 2-3 lines appear before "See more" and determine everything.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

writing-linkedin-posts is a skill published in the GitHub repository buildfastwithai/gen-ai-experiments (763 stars, last pushed yesterday), licensed MIT. It adds 75 tokens to every session and 2,311 once invoked, about $0.0004 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.
