At a glance

Covers OpenOlat's SASS theme architecture, CSS class conventions, DOM structure, and roughly 540 Java component renderers for styling work.

  • Works in 4 steps: Copy openolat/ → mytheme/, rename files → Override variables in config (key:… → Override CSS rules for logo… → …
  • Creating or customizing an OpenOlat theme
  • SKILL.md covers Technology Stack, Key Files, Theme Inheritance and Variable Naming, plus 9 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

This skill points to compressed and detailed reference docs, including an HTML version with SVG diagrams and a live component-library demo covering buttons, forms, tables, and navigation, rather than holding all of OpenOlat's frontend knowledge inline. It lists the underlying stack: Bootstrap SASS, Font Awesome, jQuery, D3.js charts, TinyMCE, FullCalendar, and Leaflet, compiled with Dart Sass through a build script.

It notes there is no client-side framework, since all UI state lives on the server, and that the main config file alone holds roughly two thousand lines of SASS variables, with accessibility helper functions for checking luminance and color contrast while building a theme.

When your agent uses it

  • Creating or customizing an OpenOlat theme
  • Debugging a DOM or layout issue in OpenOlat
  • Finding the right CSS class or SASS variable for a component

Example prompts

  • “Create a custom OpenOlat theme with a darker color palette.”
  • “Why is this OpenOlat table rendering with the wrong spacing?”
  • “Which SASS variable controls the OpenOlat button border radius?”

Requirements

  • Dart Sass 1.33 or newer
  • compiletheme.sh for compiling themes
  • Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash(sass *), Bash(./compiletheme.sh *)

Workflow steps

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

  1. Copy openolat/ → mytheme/, rename files
  2. Override variables in config (key: $brand-primary, $text-color, $link-color, $font-family-base, $o-navbar-*, $o-footer-*)
  3. Override CSS rules for logo (.o_navbar-brand), login page (#o_body.o_dmz), footer
  4. Compile: ./compiletheme.sh mytheme

What it can do on your machine

Read from SKILL.md and the folder at commit d62921e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Glob
    • Bash(sass *)
    • Bash(./compiletheme.sh *)

    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 html).

    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

OpenOlat Frontend and Theming Guide loads about 3.2k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 1,078 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~3.2k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,078 words (~3,161 tokens).

“You are an expert in OpenOlat's frontend architecture: SASS theming, CSS class conventions, DOM structure, component rendering, and responsive design. Use the knowledge below and the reference files to help developers style components, create themes, debug layout issues, and understand…”
