What it does

Enhance Theme is an agent skill from avalon60/ctk_theme_builder. Locate, modify, and optionally promote CTk Theme Builder theme JSON files

Its SKILL.md is about 350 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 Frontend & Design. It works with Python. The repository describes itself as: CTk Theme Builder for CustomTkinter, a comprehensive and easy solution, for creating CustomTkinter themes. The licence is MIT.

When your agent uses it

  • Frontend & Design work in your project

Example prompts

  • “/enhance-theme”

Workflow steps

10 steps, taken from the first numbered list in SKILL.md.

  1. Look for the theme JSON file in ~/CTkThemeBuilder/themes/, using .json.
  2. If the file does not exist, report that it was not found and do not continue with edits or promotion.
  3. Treat the file in ~/CTkThemeBuilder/themes/ as the authoritative editable source for this task.
  4. Save all requested theme changes back to ~/CTkThemeBuilder/themes/. Do not write changes to any seed theme location in the repository.
  5. If the user asks to promote the theme, copy the theme JSON file to /user_themes/.
  6. If the user asks to promote the theme to the control panel themes, copy the theme JSON file to /assets/themes/.
  7. Where a .json file exists in the ~/CTkThemeBuilder/palettes directory, and a promotion is requested, then the palette file should be…
  8. Preserve valid JSON structure and formatting when editing or copying theme files.
  9. If the promotion target already contains a file with the same name, warn before overwriting unless the user has explicitly asked to…
  10. If cannot be determined from the current working context, report that and ask for clarification before attempting promotion.

What it can do on your machine

Read from SKILL.md and the folder at commit 41a86c7. 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

Enhance Theme loads about 354 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 198 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~354

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.
