What it does
Review HTML Component Design is an agent skill from videojs/video.js. Review HTML component designs. Use for boundaries, APIs, opt-outs, and bundles.
Its SKILL.md is about 450 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: Video.js v10 - open source media player framework for HTML and React.
Example prompts
- “/review-html-component-design”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Ask whether the proposal is a reusable primitive or app/skin composition before adding an element or part.
- Trace ownership and data flow across core, DOM behavior, and the element. Check lifecycle and cleanup.
- Review light-DOM anatomy, element and CSS APIs, and whether each addition has a consumer. Leave visual structure to CSS. If the surface…
- Exercise omission, replacement, styling, behavior, and registration opt-outs.
- Weigh API complexity against bundle cost and verify side-effect boundaries. Check accessibility and interaction constraints.
What it can do on your machine
Read from SKILL.md and the folder at commit 74cf8cd. 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
Links to these hosts (documentation or services it may open):
open-ui.orglit.devw3.orgwebpack.js.org
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
Review HTML Component Design loads about 445 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 201 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 201 words (~445 tokens).
“Read the proposal, nearby records, and relevant HTML code, tests, exports, and package metadata.”
