What it does

Manage HTML Tests is an agent skill from telerik/kendo-themes. Create or update visual test scenarios for a Kendo UI component in the HTML package. Creates TSX test files that exercise component states, variants, and edge cases for screenshot-based visual regression testing. Use this skill when the user wants to add test coverage, create visual tests, or ensure a component has proper test scenarios.

Its SKILL.md is about 1.8k 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 Testing & QA, covering React components, Test coverage and Visual regression testing. The repository describes itself as: Monorepo for SASS-based Kendo UI themes.

When your agent uses it

  • The user wants to add test coverage
  • Create visual tests
  • Ensure a component has proper test scenarios

Example prompts

  • “/manage-html-tests”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Understand the component
  2. Plan test scenarios
  3. Create test files
  4. Export from index
  5. Validate

What it can do on your machine

Read from SKILL.md and the folder at commit d9705b5. 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

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Manage HTML Tests loads about 1.8k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 547 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 547 words (~1,769 tokens).

“Create visual test scenarios for a component in packages/html/src/{component}/tests/.”
