Token cost

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.

Security

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.

Origin

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:

  1. Use the task tool with subagent_type: "researcher"
  2. In the description, specify BOTH the topic AND where to save:
task(
    subagent_type="researcher",
    description="Research [TOPIC]. Save findings to research/[slug].md"
)
  1. 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:

  1. Write the post to blogs/<slug>/post.md
  2. Generate a cover image using generate_cover and save to blogs/<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.
