A blog-article writing skill that creates long-form posts about a supplied topic. It checks drafts against criteria for search visibility, reader engagement, original evidence, and sales actions.

Use it to draft 2,000–4,000-word articles from a topic, with an opening hook, readable sections, supporting numbers or experiences, and a closing action.

It gives an agent a repeatable way to structure blog posts instead of producing a generic draft. The criteria also make missing evidence, weak openings, and unclear next steps easier to spot.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01254
Opus 5.5	$0.00000	$0.00502
Sonnet 5.5	$0.00000	$0.00251

Security

Grade A, and why

write-blog 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 this file has done since we first saw it
