The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 21, 2026
Environment: Claude Code 2.x (agent harness)

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (SKILL.md not found in repo tree). The test below is what we measured on Jul 21, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Located SKILL.md at skills/blog-cover-image-cli/SKILL.md; frontmatter parses with name+description. Confirmed the referenced npm package exists (blog-cover-image-cli@1.0.17) and ran `npx -p blog-cover-image-cli blog-cover-cli --help` in a temp HOME — it printed a banner and the documented `config`/`generate` subcommands, matching the SKILL.md. Could NOT run `generate`: it needs a Gemini API key and calls Gemini's image model, so no output artifact was producible (outputMeasured=false, hence setup). No security smells — keys are stored locally via `conf`, no curl|sh, base64, or exfiltration; only minor doc overselling ("stunning", "pixel-perfect") and unverifiable model names like "Gemini 3.1 Flash Image Preview".

What Blog Cover Generator does

A thin skill wrapper around the published npm CLI `blog-cover-image-cli`, which generates 16:9 blog cover/thumbnail/header images via Gemini's image model, auto-fetching brand logos through Brandfetch. Triggers when the user asks to generate a blog cover image, article thumbnail, or post header. Requires a Gemini API key and Brandfetch client ID before it can produce anything.

How to install Blog Cover Generator
