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 | $0.00062 | $0.00338 |
| Opus 5.5 | $0.00025 | $0.00135 |
| Sonnet 5.5 | $0.00012 | $0.00068 |
| Haiku 4.5 | $0.00006 | $0.00034 |
Grade A, and why
format_markdown 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 1mo 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.
What it actually says
format_markdown
Linting Compliance
- Blank lines: One around headings, lists, tables, code blocks
- Single newline: File must end with exactly one newline
- No multiple blanks: Maximum one consecutive blank line
- Consistent bullets: Use
-for all unordered lists - Fenced code: Always use language identifier
- Table alignment: Use
:---:for center,:---for left,---:for right - Header levels: Don't skip levels (H1 → H2 → H3, not H1 → H3)
- List indentation: 2 spaces for nested items
- List marker spacing: Use 1 space after list markers
- No bare URLs: Wrap in angle brackets or use reference links
- No trailing punctuation: In headers
Best Practices
- Descriptive links: Meaningful text, not "click here"
- Alt text: Always for images
- Consistent emphasis:
**bold**and*italic*only - Table headers: Always include
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.

format_markdown is a skill published in the GitHub repository theafh/ai-modules (38 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 338 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
