What it does

Review React Component is an agent skill from videojs/video.js. Review React UI without editing code. Use for data flow, APIs, customization, styling, transitions, or bundles.

Its SKILL.md is about 700 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 React components. It works with React. The repository describes itself as: Video.js v10 - open source media player framework for HTML and React.

When your agent uses it

  • Tasks that involve React components

Example prompts

  • “/review-react-component”

Workflow steps

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

  1. Trace the source of truth, selectors, context, callbacks, and effects. Flag mirrored state, synchronization effects, broad subscriptions…
  2. Flag direct mutation of React-owned DOM or effects that synchronize rendered state; refs should be limited to browser imperatives so React…
  3. Check that each component or compound part has a scoped primitive responsibility; flag app or skin composition embedded in it. Prefer CSS…
  4. Review the whole public surface: props, callbacks, context, refs, render functions, data attributes, CSS custom properties, namespaces…
  5. Test opt-outs: optional parts can be omitted, default markup remains useful, render replacements preserve semantics, props, events, and…
  6. Inspect imports, dependencies, re-exports, client boundaries, and production tree shaking. Compound APIs should use export * as Name from…
  7. Check transition presence and races, cleanup, SSR behavior, accessibility, and tests for state flow, nested roots, prop/ref composition…

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

    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

Review React Component loads about 703 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 333 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~703

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 333 words (~703 tokens).

“Read the implementation, core and DOM contracts, rendered semantics, tests, exports, package metadata, relevant design record, and nearest comparable component.”
