Rules for creating or changing a Handsontable plugin: file layout, lifecycle, hook registration, settings, conflict registration and IndexMapper use.
- Works in 6 steps: index.ts: export { PLUGIN_KEY,… → Wire into src/plugins/index.ts. → Add the default option (disabled) in… → …
- Creating a new Handsontable plugin
- SKILL.md covers Plugin file structure, Contract, Key patterns (gold standard:… and Decoupling rules, plus 5 more sections
- Calls npm and git; needs PLUGIN_KEY
What it does
A contributor guide for plugins inside the Handsontable repository. A plugin lives in its own folder under src/plugins, with an index file that re-exports the plugin key, priority and class, and a main class that extends BasePlugin. The full contract, including statics, lifecycle order, hard conflicts and the table of plugin priorities, is kept in src/plugins/base/AGENTS.md, and a new plugin picks a free priority number and adds its row to that table.
Key patterns follow the pagination plugin as the model. Internal state uses # private fields, hook callbacks are passed to addHook as arrow-function class fields so the registered reference can be removed later, and addHook on the plugin cleans up on disablePlugin while the one on the hot instance does not. Settings are read with getSetting, conflicts are registered at module level and checked in enablePlugin, and index maps are created in enablePlugin and unregistered in disablePlugin, using a hiding map to keep rows in the data or a trimming map to remove them. UI goes in its own class with injected dependencies.
When your agent uses it
- Creating a new Handsontable plugin
- Adding hooks or options to an existing plugin
- Working with the enablePlugin, disablePlugin and updatePlugin lifecycle
- Registering conflicts between plugins or integrating an IndexMapper
Example prompts
- “Create a new Handsontable plugin that hides rows by a custom rule.”
- “Add a beforeMyAction hook to the filters plugin and register the hook name.”
- “Make my plugin conflict with nestedRows and mergeCells.”
Requirements
- A checkout of the Handsontable repository
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- index.ts: export { PLUGIN_KEY, PLUGIN_PRIORITY, ClassName } from './pluginName';
- Wire into src/plugins/index.ts.
- Add the default option (disabled) in src/dataMap/metaManager/metaSchema.ts.
- For new hook signatures or settings, add them to src/core/settings.ts (GridSettings); npm run build:types regenerates the public .d.ts…
- Write AGENTS.md and symlink CLAUDE.md to it with the relative target, so the link resolves in a git worktree
- Add your PLUGIN_PRIORITY row to the table in src/plugins/base/AGENTS.md, in the same change: nothing enforces it, so it drifts silently.
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:
npmgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and git, 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 these keys or tokens, usually read from environment variables:
PLUGIN_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Handsontable Plugin Development loads about 2.3k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 1,038 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 1,038 words (~2,319 tokens).
“Statics (PLUGIN_KEY, PLUGIN_PRIORITY, SETTING_KEYS, PLUGIN_DEPS, DEFAULT_SETTINGS, SETTINGS_VALIDATORS), lifecycle order, onUpdateSettings, hard conflicts, and the PLUGIN_PRIORITY table: src/plugins/base/AGENTS.md. Pick a free priority number from that table and add your row to it.”
