What it does
Element Runtime Assets is an agent skill from PrairieLearn/PrairieLearn. Use when creating a new PrairieLearn element or changing an element's runtime dependencies, scripts, styles, or bundled assets.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Online problem-driven learning system.
When your agent uses it
- Creating a new PrairieLearn element
- Changing an elements runtime dependencies
Example prompts
- “/element-runtime-assets”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Create or update the element's controller, template, CSS, JavaScript, and info.json together.
- Keep the runtime asset wiring in info.json aligned with the actual files that are shipped and loadable in the browser.
- Update the element docs and example-course questions when author-facing behavior changes.
- Verify the asset path in the browser or via the app's asset-serving checks before calling the change complete.
What it can do on your machine
Read from SKILL.md and the folder at commit 92584fe. 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
Element Runtime Assets loads about 723 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 377 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
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 377 words (~723 tokens).
“Use this when adding a new element under apps/prairielearn/elements/ or when changing how an element loads JavaScript, CSS, or other runtime assets.”
