blog-image

AI image generation and editing for blog content powered by Gemini via MCP. Claude acts as Creative Director - interpreting intent, selecting domain expertise, constructing optimized 6-component prompts (Subject + Action + Context + Composition + Lighting + Style), and orchestrating Gemini for blog-quality results. Generates hero images, inline illustrations, social preview cards, and OG images. Edits existing blog images. Supports 6 blog-optimized domain modes (Editorial, Product, Landscape, UI/Web, Infographic, Abstract). Works standalone via /blog image or internally from blog-write and blog-rewrite workflows. Falls back gracefully when MCP is not configured. Use when user says "blog image", "generate hero image", "blog illustration", "social card", "generate blog image", "edit blog image", "image generate", "blog cover image", "inline image", "OG image".

Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, actionable skill body that pairs concrete executable guidance with clearly sequenced workflows and validation checkpoints, while keeping detailed material in verified one-level-deep references. It is lean and assumes Claude's intelligence throughout.

DimensionReasoningScore

Conciseness

The body is lean and table-driven with executable commands and templates, assuming Claude's competence; it does not explain concepts Claude already knows (what a blog/MCP/PNG is), and nearly every token earns its place.

3 / 3

Actionability

Guidance is fully executable: concrete `magick` post-processing commands, named MCP tools with parameters like `conversation_id: "default"`, fill-in prompt templates, and exact setup script invocations with flags — all copy-paste ready.

3 / 3

Workflow Clarity

The generation workflow is a clearly sequenced Steps 1-7 with an MCP availability check, Setup includes an explicit validate step, and the safety auto-rephrase loop (max 3 attempts) plus the error-handling table provide explicit validation checkpoints and feedback loops.

3 / 3

Progressive Disclosure

SKILL.md is an overview pointing to one-level-deep references (prompt-engineering-blog.md, gemini-models.md, mcp-tools.md), all of which exist, clearly signaled with inline "Load `references/...`" cues and a "Load on-demand - do NOT load all at startup" directive; scripts are separated out.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that names concrete capabilities, lists natural trigger phrases, and explicitly states both what it does and when to use it in third-person voice. The blog-specific framing makes it clearly distinguishable from other image skills.

DimensionReasoningScore

Specificity

"Generates hero images, inline illustrations, social preview cards, and OG images, and edits existing ones" and "Supports 6 domain modes (Editorial, Product, Landscape, UI/Web, Infographic, Abstract)" list multiple specific concrete actions rather than vague language.

3 / 3

Completeness

It clearly answers what the skill does (blog image generation/editing with 6 domain modes) and when to use it via an explicit "Use when..." trigger clause, satisfying both halves.

3 / 3

Trigger Term Quality

The explicit "Use when user says 'blog image', 'generate hero image', 'blog illustration', 'edit blog image', 'OG image'" provides natural quoted phrases a user would actually say, with good coverage of variations.

3 / 3

Distinctiveness Conflict Risk

The blog-content + Gemini-MCP niche and triggers like "blog image" and "OG image" are distinct from generic image skills and unlikely to fire for the wrong skill; voice is third person throughout.
