Review Video.js TypeScript APIs without editing code. An agent skill from videojs/video.js.

  • Architecture audits
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Review API is an agent skill from videojs/video.js. Review Video.js TypeScript APIs without editing code. Use for inference, state, extensibility, composition, packaging, or architecture audits.

Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/checklist.md`).

It works with TypeScript. The repository describes itself as: Video.js v10 - open source media player framework for HTML and React.

When your agent uses it

  • Architecture audits

Example prompts

  • “/review-api”

Workflow steps

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

  1. Define the changed or proposed public surface and compatibility constraints.
  2. Check runtime behavior, inference, naming, defaults, composition, escape hatches, lifecycle, packaging, and adjacent API consistency.
  3. Use references/checklist.md for a broad audit; load only the sections relevant to the surface.
  4. Tie every finding to a concrete caller, failure mode, or maintenance cost.

What it can do on your machine

Read from SKILL.md and the folder at commit 50f59a2. 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 API loads about 273 tokens when it runs, and up to ~658 if it reads all its reference files. Until then it costs about 38 tokens; SKILL.md has 124 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~273
With references · SKILL.md plus every file in references/, read only if the agent opens them
~658

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 124 words (~273 tokens).

“Read the implementation, public exports, callers, types, tests, and relevant design records.”
