What it does

Pbgui CSS Tokens is an agent skill from msei99/pbgui. PBGui CSS design tokens for FastAPI frontend pages. Use when writing or reviewing CSS in frontend/.html files, or when migrating hardcoded px/rem font sizes to var(--fs-) tokens. Covers font sizes (XS–XL), spacing (--sp-), input/button heights. Trigger: CSS, font-size, spacing, design tokens, --fs-, --sp-, px, rem, frontend HTML.

Its SKILL.md is about 1.1k 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, covering Design tokens and Backend development. It works with FastAPI.

When your agent uses it

  • Reviewing CSS in frontend/.html files
  • Migrating hardcoded px/rem font sizes to var(--fs-) tokens

Example prompts

  • “/pbgui-css-tokens”

Workflow steps

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

  1. Add the :root block (above) inside at the top of the file
  2. Set html, body { font-size: var(--fs-base); }
  3. Search for font-size: in the file and replace each value using the mapping table
  4. Search for padding:, gap:, margin: and replace spacing values using --sp-*
  5. For input, select, button: add height: var(--input-h) / height: var(--btn-h)
  6. Validate: no hardcoded px/rem font-size values should remain (except inside :root)

What it can do on your machine

Read from SKILL.md and the folder at commit 3151916. 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 (its code samples are css).

    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

Pbgui CSS Tokens loads about 1.1k tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 430 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.
