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.

SkillSpector: 3 findings, up to high
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 →
- high Agent Snooping · line 252 Skill reads from agent configuration directories (.claude/, .codex/, .gemini/). These directories may contain API keys, personal settings, and other credentials that the skill has no legitimate need to access.Fix: Remove all code or instructions that access agent configuration directories (.claude/, .codex/, .gemini/). If configuration values are needed, pass them explicitly as parameters or environment variabl
- medium Rogue Agent · line 204 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium System Prompt Leakage · line 298 Skill contains patterns that could indirectly extract system prompts through rephrasing, translation, summarization, or side-channel techniques.Fix: Guard against indirect extraction by refusing to summarize, translate, or rephrase system instructions. Add explicit anti-extraction clauses.
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 | $0.00176 | $0.03327 |
| Opus 5 | $0.00088 | $0.01664 |
| Sonnet 5 | $0.00035 | $0.00665 |
| Haiku 4.5 | $0.00018 | $0.00333 |
Grade B, and why
blog-image scanned grade B with 1 finding 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 12d 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.

How it starts
The opening of the file, as written. The whole thing — 309 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Image - AI Image Generation for Blog Content
You are a Creative Director that orchestrates Gemini's image generation specifically for blog content. Never pass raw user text directly to the API. Always interpret, enhance, and construct an optimized prompt using the 6-component Reasoning Brief system.
Quick Reference
| Command | What it does |
|---|---|
/blog image generate <idea> |
Generate a blog image with full prompt engineering |
/blog image edit <path> <instructions> |
Edit an existing blog image intelligently |
/blog image setup |
Configure MCP server and API key |
Blog Image Types
Match the image type to blog use case:
| Image Type | Aspect Ratio | Resolution | Domain Mode | Placement |
|---|---|---|---|---|
| Hero/Cover | 16:9 |
2K or 4K | Editorial / Landscape | Frontmatter coverImage |
| OG/Social Card | 16:9 |
1K | Editorial / Infographic | Frontmatter ogImage |
| Inline Illustration | 16:9 or 4:3 |
1K | Varies by topic | After H2, before body |
| Inline Product Shot | 4:3 or 1:1 |
1K | Product | Within product sections |
| Section Divider | 21:9 then crop |
1K | Abstract / Landscape | Between major sections |
Sizing requirements:
- Blog hero/cover: 1200x630 (OG-compatible) or 1920x1080
- Open Graph (OG): 1200x630 (required for social sharing)
- Inline images: 1200px+ wide
MCP Availability Check
Before generating, check if nanobanana-mcp tools are available:
- Try calling
get_image_historywithconversation_id: "default"(lightweight, no side effects) - If it succeeds: MCP is available, proceed with generation
- If it fails: MCP not configured - inform the user:
- "Image generation requires the nanobanana-mcp server. Run
/blog image setupto configure it." - When called internally (from blog-write/blog-rewrite): return silently, no error. The calling workflow continues with stock photos.
- "Image generation requires the nanobanana-mcp server. Run
Generation Workflow
For /blog image generate <idea> or when invoked internally:
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.
- 12d ago First seen · 309 lines · 176 tokens per session scan B b19d04b3cddc
blog-image is a skill published in the GitHub repository AgriciDaniel/claude-blog (2,125 stars, last pushed yesterday), licensed MIT. It adds 176 tokens to every session and 3,327 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
