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 AGENTS.md 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 3d 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.

Article Structure

Articles are plain Markdown (.md). Each follows this structure:

# Article Title<br><span style="...">Optional Subtitle</span>

Category  ·  Subcategory

    Article Title Repeated
(Optional Subtitle)

    Axel Freeman  ·  DATE  ·  X min read

        **Bold summary paragraph.** The key takeaway, 2-4 sentences.

    ## Section Heading

    Content paragraphs...

        ### Callout Box Title
        Callout content with key insight or actionable advice.

Key Conventions

  1. Title line — uses <br> for line breaks, for styled subtitles
  2. Category line — Category · Subcategory (e.g., AI Marketing · Opinion, AI Marketing · Content)
  3. Author line — Axel Freeman · DATE · X min read (indented with 4 spaces)
  4. Summary paragraph — bold, 2-4 sentences, indented with 8 spaces, captures the article's core argument
  5. Section headings — ## Heading (H2), no H1 after the title
  6. Callout boxes — ### Emoji Callout Title followed by content, indented
  7. Paragraphs — indented with 4 spaces
  8. Emphasis — bold for key phrases, sparing inline code for terms

Bilingual Convention

  • English articles: <slug>-en.md (e.g., claude-vs-hermes-marketing-en.md)
  • Russian articles: <slug>.md (e.g., claude-vs-hermes-marketing.md)

When creating a new article, always produce both versions. English is the primary public-facing version; Russian serves the RU-speaking audience on axelfreeman.ru.

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.
