What it does
This skill produces Preline UI theme CSS by reading a fixed set of docs in order - a workflow guide, palette guidance, final output style rules, and a validation checklist - and then generating the actual CSS only through a bundled generator script, after resolving the target theme directory with a separate lookup script.
It handles three modes: previewing generated CSS without writing a file, writing a new theme file, or validating and fixing an already-generated theme's token coverage against a reference document. Typical requests include matching a specific brand hex color, turning a mood like cyberpunk or sunset into a light and dark theme pair, or reviewing an existing theme file against the validation checklist.
It is deliberately locked down: no npx or network-fetched packages, no interpolating raw user text into shell commands, no broad directory traversal for locating the themes folder, and no writing outside a confirmed theme directory or creating extra project files beyond the theme itself.
When your agent uses it
- Generating a new Preline theme that matches a brand color
- Turning a mood or style into a light and dark Preline theme pair
- Reviewing a generated Preline theme for missing tokens
Example prompts
- “Create a sunset-themed Preline CSS file with matching dark mode.”
- “Match this brand color to a new Preline theme: #2F6BFF.”
- “Preview a cyberpunk dark theme before writing any files.”
Requirements
- The skill's bundled theme-generator scripts
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Read docs/workflow.md.
- Read docs/palette-guidance.md.
- Read docs/final-output-style.md before writing a final theme file.
- Read docs/validation-checklist.md before closing the task.
- Read examples.md only if the user wants stylistic guidance or sample outputs.
- Read docs/token-reference.md only if you need to inspect token coverage in detail.
What it can do on your machine
Read from SKILL.md and the folder at commit 05ca599. 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
Ships 3 files in scripts/ (JavaScript), which the agent can run.
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
Preline Theme Generator loads about 619 tokens when it runs. Until then it costs about 108 tokens; SKILL.md has 258 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

The automated check found patterns that need a careful read before installing.
