Explains how to add or change the demo pages that Handsontable's visual regression suite photographs, including per-feature routes in the js demo and the shared grid.

  • Adding a demo route for a new feature to the visual regression suite
  • SKILL.md covers Decision rule, Example location, Directory structure and How to add a feature route, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Changing an existing demo whose screenshots the suite compares

What it does

The visual suite renders Vite demo apps for js, react-wrapper, vue3 and angular-wrapper, served on port 8082 by `visual-tests/scripts/run-tests.mjs`. The js demo is a single app with a Navigo router: the root route shows a shared multi-feature grid that must stay identical across frameworks, and every feature gets its own route ending in `-demo`, backed by a module under `src/demos`. The wrapper demos serve only the root, apart from a `/scenario-grid` route in the React and Angular wrappers. The docs examples tree belongs to a different skill.

Adding a feature takes four steps. Create a module that exports `init()` and builds the grid inside `#root`, reading per-route options from the URL with `getFromURL()` so one route can show several states. Register the route in `src/index.js` with the stylesheet and theme loading. Import from `handsontable/base` and register only the plugins and cell types the module needs, not the full bundle. Then write the visual spec under `visual-tests/tests/js-only`. A screenshot proves pixels only, so it supplements a Playwright assertion in `tests/e2e` and never replaces it.

When your agent uses it

  • Adding a demo route for a new feature to the visual regression suite
  • Changing an existing demo whose screenshots the suite compares
  • Checking that the shared root grid stays the same across framework demos

Example prompts

  • “Add a visual demo route for the new column summary feature and a spec that photographs it.”
  • “The filters demo needs a second visual state. Extend its route to read the option from the URL.”
  • “Why does the vue3 demo have no route for my new feature?”

Requirements

  • The Handsontable repository checkout with its visual-tests suite

What it can do on your machine

Read from SKILL.md and the folder at commit fff66b1. 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 (its code samples are javascript).

    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

Handsontable Visual Test Demos loads about 1.3k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 489 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 489 words (~1,294 tokens).

“Covers the demo apps the visual suite (visual-tests/) renders: examples/next/visual-tests/{js,react-wrapper,vue3,angular-wrapper}/demo/, served on port 8082 by visual-tests/scripts/run-tests.mjs. The documentation examples in examples/next/docs/ are another tree, owned by the creating-docs-examples skill, and the visual suite does not serve it.”
