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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 198 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00135 | $0.04448 |
| Opus 5 | $0.00068 | $0.02224 |
| Sonnet 5 | $0.00027 | $0.00890 |
| Haiku 4.5 | $0.00014 | $0.00445 |
Grade A, and why
blog-cluster 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 — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Cluster (Semantic Topic Cluster Engine)
Plans and executes entire interlinked content ecosystems from a single seed keyword. Three layers: Semantic Clustering (the brain), Cluster Architecture (the structure), and Execution Engine (the machine).
Adapted from the semantic-cluster-engine submission by Lutfiya Miller (winner, AI Marketing Hub Pro Challenge, March 2026, 95/100 Exemplary). Original repository: https://github.com/Drfiya/semantic-cluster-engine This port keeps the Plan + Execute architecture and the cluster context innovation, removes brand-specific (ScienceExperts.ai) styling and image prompts, and routes through claude-blog's existing sub-skills.
Commands
| Command | What it does |
|---|---|
/blog cluster |
Interactive. Asks whether to plan or execute. |
/blog cluster plan <seed-keyword> |
SERP-based semantic analysis. Outputs cluster plan + map. |
/blog cluster plan --from strategy [path] |
Imports existing blog-strategy cluster build plan and validates against SERP data. |
/blog cluster execute [path-to-plan] |
Sequential blog-write calls with cluster context and auto-interlinks. |

Cross-references to existing claude-blog skills
| Skill | When this skill calls it |
|---|---|
/blog strategy |
Upstream planning. plan --from strategy consumes its Cluster Build Plan tables. |
/blog write |
Per-post execution. Each spoke and the pillar are produced by blog-write with a prepended cluster-context block. |
/blog chart |
Invoked internally by blog-write for inline SVG charts. No direct call from this skill. |
/blog image |
Optional hero image generation per post. Model selection is delegated to blog-image; prefer current Gemini image models when available. |
/blog seo-check |
Recommended after execution for per-post on-page validation. |
/blog cannibalization |
Recommended after execution to confirm zero keyword overlap across the cluster. |
/blog schema |
Recommended after execution to add BreadcrumbList, ItemList, and Article schema. |
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-cluster is a skill published in the GitHub repository AgriciDaniel/claude-blog (2,116 stars, last pushed 7d ago), licensed MIT. It adds 135 tokens to every session and 4,448 once invoked, about $0.0007 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 2026-08-30.
