What it does
Cover Design Psychology is an agent skill from revfactory/harness-100. A specialized skill for the cover-designer agent covering cover design psychology. Provides genre-specific cover conventions, typography strategy, color psychology, thumbnail testing, and AI image generation prompt design. Use for 'cover design,' 'book cover,' 'genre covers,' 'cover concept,' and similar topics.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Typography, Image generation and Prompt engineering. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Typography
- Tasks that involve Image generation
- Tasks that involve Prompt engineering
Example prompts
- “cover design,”
- “book cover,”
- “genre covers,”
- “/cover-design-psychology”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 3 words or fewer: Long titles prevent large font sizes
- Hierarchy: Title > Subtitle > Author name in descending size
- Color Contrast: Background-to-text contrast ratio 4.5:1 or higher
- Whitespace: Sufficient margins around text (breathing room)
- Thumbnail Test: Is the title readable when shrunk to 3cm x 4cm?
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cover Design Psychology loads about 1.3k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 461 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
