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.

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 →

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 | $0.00052 | $0.00973 |
| Opus 5 | $0.00026 | $0.00487 |
| Sonnet 5 | $0.00010 | $0.00195 |
| Haiku 4.5 | $0.00005 | $0.00097 |
Grade A, and why
blog-cover-generator 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 8d 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.

Blog Cover Generator Skill
This skill provides AI agents with the ability to generate stunning, minimalist, technical blog cover images using the blog-cover-image-cli. The CLI leverages Gemini 3.1 Flash Image Preview, automatically fetches brand logos from domains, uses local aesthetic reference images, and employs Google Search grounding to inject real-time context.
Setup & Configuration
Agent Pre-requisites:
Before using this tool, verify it is installed. If blog-cover-cli --help fails, install it globally:
npm install -g blog-cover-image-cli
If the user wants you to generate an image and you haven't set up the API key yet, you must first configure the CLI using a Gemini API Key. The CLI stores this securely via the conf package.
# 1. Set your Gemini API Key (Required for image generation)
npx -p blog-cover-image-cli blog-cover-cli config set-key <YOUR_GEMINI_API_KEY>
# 2. Set your Brandfetch Client ID (Required to fetch high-res logos)
npx -p blog-cover-image-cli blog-cover-cli config set-brandfetch-id <YOUR_BRANDFETCH_CLIENT_ID>
# Check your keys (masked)
npx -p blog-cover-image-cli blog-cover-cli config get-key
npx -p blog-cover-image-cli blog-cover-cli config get-brandfetch-id
Usage: Generating an Image
When a user asks for a cover image (e.g., "Create a cover image for my blog about Vercel v0"), you should use the generate command.
npx -p blog-cover-image-cli blog-cover-cli generate -t "The Title of the Blog Post" -l "example.com"
Arguments
-t, --title <text>: (Required) The title text to display on the cover image. Do not use excessively long titles (keep it under 3 lines of text visually).-l, --logo <domain>: (Optional but recommended) The domain to fetch the brand logo from (e.g.,vercel.com,google.com,cursor.com). The CLI automatically converts WebP/SVG/AVIF to PNG for compatibility.-o, --output <path>: (Optional) The file path where the generated image will be saved. If omitted, the CLI automatically saves it to anoutput/directory in the current working folder (e.g.,./output/vercel-cover.png).
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
