What this skill tells your AI

The instructions your AI receives, as published by htmlstreamofficial/preline in skills/theme-generator/SKILL.md and read by ahel’s review.

Use the bundled local scripts. Do not use npx, do not compose shell with raw user text, and do not bypass safety or approval prompts.

Read Order

  1. Read docs/workflow.md.
  2. Read docs/palette-guidance.md.
  3. Read docs/final-output-style.md before writing a final theme file.
  4. Read docs/validation-checklist.md before closing the task.
  5. Read examples.md only if the user wants stylistic guidance or sample outputs.
  6. Read docs/token-reference.md only if you need to inspect token coverage in detail.

Workflow

Follow docs/workflow.md for the full operating path.

Key requirements:

  1. Identify whether the task is preview, write, or validate.
  2. Normalize the request into explicit generator inputs.
  3. Resolve the target directory with scripts/find-themes-dir.js.
  4. Generate CSS only through scripts/run-theme-generator.js.
  5. Create or edit only the new theme file.
  6. Validate with docs/validation-checklist.md.
  7. Return the result in the mode-appropriate format.

Security Constraints

  • Never use wording that attempts to bypass tool or approval safeguards.
  • Never use npx or any network-fetched package for this skill.
  • Never interpolate raw user text directly into shell commands.
  • Never use broad find . traversal for path discovery; use scripts/find-themes-dir.js or a user-confirmed path.
  • Never write outside a confirmed theme directory.
  • Use scripts/run-theme-generator.js as the only execution entry point for generation.
  • Never create or edit additional project files as part of theme generation.

Common Prompts

  • "Create a sunset theme."
  • "Match this brand color: #2F6BFF."
  • "Generate a cyberpunk dark theme with matching dark mode."
  • "Preview the CSS before writing a file."
  • "Review this generated theme and fix token coverage."
