At a glance
Routes any change to the handsontable core package to the right specialist skill, by task type such as plugin, editor, renderer or validator, after a mandatory architecture review.
- Works in 6 steps: Generalize the signature, add zero as… → .d.ts files → import type for types → …
- Fixing a bug or adding a feature anywhere under handsontable/src/
- SKILL.md covers Dispatch table, Design rules from…, File layout and TypeScript gotchas, plus 6 more sections
- Calls npm and node
What it does
This is the entry point for development on the handsontable/ core package, excluding the separate Walkontable rendering engine subfolder, which has its own skill. Before any task-specific work, it requires loading handsontable-code-review first for the architecture lens, which enforces plugin decoupling through hooks and hot.getPlugin rather than direct references, conflict ownership through registerConflict for hard incompatibilities, the Law of Demeter through TableView or Core rather than reaching into wt.wtTable chains, and the full BasePlugin lifecycle contract.
A dispatch table then routes the actual implementation work: handsontable-plugin-dev, handsontable-editor-dev, handsontable-renderer-dev, handsontable-validator-dev and handsontable-celltype-dev for creating or modifying those respective pieces, handsontable-playwright-e2e for new end-to-end tests versus handsontable-e2e-testing for frozen legacy spec files, handsontable-unit-testing for unit tests, handsontable-demo-page for demo pages, handsontable-css-dev for styling, coordinate-systems for physical, visual and renderable coordinate translation, and i18n-translations for translation work.
When your agent uses it
- Fixing a bug or adding a feature anywhere under handsontable/src/
- Writing or modifying a plugin, editor, renderer, validator or cell type
- Understanding plugin lifecycle, coordinate systems or hook registration in the core grid
- Deciding which specialist skill a core Handsontable task should be routed to
Example prompts
- “Add a new validator plugin to handsontable that checks for valid IBANs.”
- “I'm getting a coordinate mismatch between physical and visual rows; help me debug it.”
- “Fix a bug in the cell renderer for the dropdown cell type.”
- “Which skill should handle adding a new hook to the plugin lifecycle?”
Requirements
- The handsontable/handsontable repository checked out locally
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Generalize the signature, add zero as casts
- .d.ts files
- import type for types
- Import shared types from core/
- Private fields use #, callbacks are arrow-function class fields
- Cognitive complexity ≤ 15 per function
What it can do on your machine
Read from SKILL.md and the folder at commit 68b5e97. 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:
npmnode
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
Handsontable Core Development loads about 3.3k tokens when it runs. Until then it costs about 178 tokens; SKILL.md has 1,296 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 1,296 words (~3,254 tokens).
“Load handsontable-code-review (architecture dimension) first for every change, then the task-specific specialist. It is the design lens (SOLID, Law of Demeter, plugin decoupling, breaking changes); the task skill is the implementation guide.”
