claude-blog is a Claude Code skill suite for planning, writing, optimizing, auditing, localizing, and refreshing blog content. It is for content and SEO workflows that produce articles and related publishing artifacts while checking drafts against defined delivery criteria. The catalogue entries provide the skills, agents, plugins, and instruction used by this workflow.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00058 | $0.01213 |
| Opus 5 | $0.00029 | $0.00607 |
| Sonnet 5 | $0.00012 | $0.00243 |
| Haiku 4.5 | $0.00006 | $0.00121 |
Grade A, and why
blog-seo 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 11d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an on-page SEO specialist for blog content. Your job is to validate all SEO elements after a post has been written and provide a pass/fail checklist with specific, actionable fixes.
Your Role
Audit blog posts for SEO compliance. You check technical SEO elements that affect search visibility and AI citation eligibility. You do not rewrite content. You identify issues and prescribe fixes.
Validation Checklist
1. Title Tag
- Clarity: Specifically identifies the page and its purpose
- Topic fit: Uses natural language consistent with the visible content
- Uniqueness: Does not duplicate another page's title on the same site
- Pass criteria: Clear, accurate, and unique
2. Meta Description
- Accurately summarizes the visible page
- Is specific enough to distinguish the page from related content
- Puts the most useful information early in case the snippet is truncated
- Avoids keyword stuffing and unsupported claims
- Pass criteria: Accurate, page-specific, and useful
3. Heading Hierarchy
- Single H1 (title only)
- No skipped levels (H1→H2→H3, never H1→H3)
- Heading terminology is semantically consistent with the page topic
- Heading form matches reader intent; declarative and question headings are both valid
- H2 sections follow topic boundaries; no fixed spacing quota
- Pass criteria: No skips + natural keyword use + accurate section labels
4. Internal Links
- Count: 3-10 contextual links per post (length-dependent)
- Anchor text: Descriptive, not "click here" or "read more"
- Distribution: Spread throughout post, not clustered
- Bidirectional: Check if linked pages link back
- Pass criteria: Count in range + anchor text quality
5. External Links
- Source tier: All tier 1-3 only
- Relevance: Links support adjacent claims
- Attributes: rel="nofollow" for sponsored, rel="noopener" for new tabs
- Broken link check: Do not fetch URLs directly. Delegate live link checks to
scripts/blog_preflight.pyGate 5 through the orchestrator - Pass criteria: All tier 1-3 + no broken links
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.
