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.

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 | $0.00122 | $0.01331 |
| Opus 5 | $0.00061 | $0.00665 |
| Sonnet 5 | $0.00024 | $0.00266 |
| Haiku 4.5 | $0.00012 | $0.00133 |
Grade A, and why
blog-post-writer 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Post Writer
Overview
This skill produces publishable technical blog posts that readers actually finish: a hook that earns the first scroll, a spine of clear sections, runnable examples, and a takeaway the reader can act on. Keywords: blog post, technical article, dev blog, tutorial, write-up, engineering blog, Medium, dev.to, Hashnode, announcement, essay, headline, hook, SEO.
Use it for tutorials, deep dives, "how we built X" stories, opinion/architecture pieces, release announcements, and concept explainers.
When To Use
- "Write a blog post about ."
- "Turn these notes / this PR / this RFC into an article."
- "I need a catchy intro and outline for a post on ."
- "Edit / tighten this draft."
Process
Follow these steps in order. Do not skip step 1 — most weak posts fail on audience and angle, not prose.
- Clarify the brief. Establish (ask only if unknown): topic, target reader and their skill level, the single takeaway, desired length, tone, and platform. If the user gave a draft or notes, infer these and confirm the angle in one line.
- Find the angle. Pick ONE controlling idea (the "so what"). Reject topics that are really 3 posts; split them. Write a one-sentence thesis you can defend.
- Outline. Produce a section skeleton (H2s) before prose. Use
templates/outline.md. Aim for 4-7 sections plus intro and conclusion. - Write the hook. Draft the opening using a pattern from
references/hooks.md. The first two sentences must create tension or promise a payoff. No "In today's fast-paced world." - Draft body. One idea per section. Lead each section with its point, then support with example/code/data. Keep paragraphs 2-4 sentences.
- Add examples. Every abstract claim gets a concrete instance: code, a command, a number, a before/after, or a short scenario. Code must be minimal, correct, and runnable.
- Write the takeaway. End with what the reader should now do or believe — a checklist, next step, or crisp summary. Never end on "In conclusion."
- Title + meta. Generate 3-5 headline options (see
references/headlines.md) and a 150-160 char meta description. - Edit. Run the pass in
references/editing-checklist.md. Then runscripts/readability.pyon the draft for objective metrics. Cut 10%.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

blog-post-writer is a skill published in the GitHub repository JayRHa/AgentSkills (4 stars, last pushed 1mo ago), licensed MIT. It adds 122 tokens to every session and 1,331 once invoked, about $0.0006 per session on Opus 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 2026-08-31.
