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 | $0.00054 | $0.01252 |
| Opus 5 | $0.00027 | $0.00626 |
| Sonnet 5 | $0.00011 | $0.00250 |
| Haiku 4.5 | $0.00005 | $0.00125 |
Grade A, and why
social-post-ab-variants-writer 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 12d 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.

Social Post A/B Variants Writer
What This Skill Does
Generates two or three distinct social media post variants for the same article or piece of content, each testing a different angle, hook, or emotional register, so you can run a controlled comparison and learn what resonates with your audience.
When To Use This Skill
- You are publishing a new article, video, or episode and want to promote it across social media without committing to a single framing before you know what works
- Your publication has enough followers to generate meaningful engagement data and wants to make distribution decisions based on evidence rather than instinct
- You need copy for a scheduled social media test — two posts going out at similar times to different audience segments, or sequentially over several days
- A previous post underperformed and you want to relaunch the same content with different framings
What You Need To Provide
Required: The headline or title of the piece, a one-paragraph summary of what the article covers, and the platform you are posting to (LinkedIn, X/Twitter, Instagram, Facebook, or Bluesky).
Optional: The primary audience segment (general public, specialists, decision-makers); any constraints on length or tone set by your publication's style guide; the specific hypothesis you want to test (e.g., "curiosity-gap hook vs. direct statement of fact"); any call-to-action wording you want to keep consistent across variants.
How the Assistant Approaches This
- Identifies three proven copywriting angles for the piece — typically: a direct news statement, a curiosity or question hook, and an emotional or human-interest angle — and selects the two or three that are most plausible given the content.
- Drafts each variant independently, keeping the article link and any fixed call-to-action identical across variants but varying the opening sentence, emotional register, and framing strategy. Each variant is genuinely different — not the same post with one word swapped.
- Labels each variant with its hypothesis (what it is testing), so the social media team can interpret results without needing to decode the copy themselves. Notes any platform-specific formatting (character limits, hashtag conventions, emoji norms).

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.
