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 | $0.00087 | $0.03605 |
| Opus 5 | $0.00044 | $0.01802 |
| Sonnet 5 | $0.00017 | $0.00721 |
| Haiku 4.5 | $0.00009 | $0.00361 |
Grade A, and why
content-writing 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.

The opening of the file, as written. The whole thing — 551 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Writing
Create ridiculously good content using Ann Handley's "Everybody Writes" methodology—practical, reader-focused writing that serves your audience and achieves your goals.
When to Use This Skill
Use this skill when you need to:
- Write blog posts that engage and convert readers
- Create email content that gets opened and clicked
- Craft social media posts that stop the scroll
- Develop website copy that speaks to your audience
- Write thought leadership that builds credibility
- Improve existing content that's underperforming

Methodology Foundation
Source: Ann Handley - Everybody Writes: Your Go-To Guide to Creating Ridiculously Good Content (2014, 2nd edition 2022)
Core Principle: Writing isn't a gift—it's a skill. Writing well is part habit, part knowledge of fundamental rules, and part giving a damn about your reader.
"No one will ever complain that you've made things too simple to understand."

- Adapt to specific formats - Headlines, emails, social, long-form
- Build sustainable habits - Consistent quality output
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.
