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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00058 | $0.00961 |
| Opus 5 | $0.00029 | $0.00481 |
| Sonnet 5 | $0.00012 | $0.00192 |
| Haiku 4.5 | $0.00006 | $0.00096 |
Grade A, and why
blog-post 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 6d 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.
This is a copy
88% identical to blog-post — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Post Writing Skill
Research First (Required)
Before writing any blog post, you MUST delegate research:
- Use the
tasktool withsubagent_type: "researcher" - In the description, specify BOTH the topic AND where to save:
task(
subagent_type="researcher",
description="Research [TOPIC]. Save findings to research/[slug].md"
)
- After research completes, read the findings file before writing
Output Structure (Required)
Every blog post MUST have both a post AND a cover image:
blogs/
└── <slug>/
├── post.md # The blog post content
└── hero.png # REQUIRED: Generated cover image
You MUST complete both steps:
- Write the post to
blogs/<slug>/post.md - Generate a cover image using
generate_coverand save toblogs/<slug>/hero.png
A blog post is NOT complete without its cover image.
Blog Post Structure
Every blog post should follow this structure:
1. Hook (Opening)
- Start with a compelling question, statistic, or statement
- Make the reader want to continue
- Keep it to 2-3 sentences
2. Context (The Problem)
- Explain why this topic matters
- Describe the problem or opportunity
- Connect to the reader's experience
3. Main Content (The Solution)
- Break into 3-5 main sections with H2 headers
- Each section covers one key point
- Include code examples, diagrams, or screenshots where helpful
- Use bullet points for lists
4. Practical Application
- Show how to apply the concepts
- Include step-by-step instructions if applicable
- Provide code snippets or templates
5. Conclusion & CTA
- Summarize key takeaways (3 bullets max)
- End with a clear call-to-action
- Link to related resources
Cover Image Generation
After writing the post, generate a cover image using the generate_cover tool:
generate_cover(prompt="A detailed description of the image...", slug="your-blog-slug")
The tool saves the image to blogs/<slug>/hero.png.
Writing Effective Image Prompts
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.
