Development

Prerequisites

VS Code with the Dev Containers extension, or Node.js 22+ installed locally
npm install to install dependencies

Editing a theme

The three theme files live in themes/:

File	Theme
`themes/esacteksab-kai-default.json`	Default
`themes/esacteksab-kai-atlantis.json`	Atlantis
`themes/esacteksab-kai-vivid.json`	Vivid

To preview changes live, press F5 in VS Code. This opens an Extension Development Host window with the modified theme loaded. Changes to the JSON files are picked up immediately — no restart needed.

Releasing a new version

Edit the theme JSON files with your changes.

Bump the version in package.json following semver:

npm version patch   # 0.0.5 → 0.0.6 (bug fix / color tweak)
npm version minor   # 0.0.5 → 0.1.0 (new theme variant)
npm version major   # 0.0.5 → 1.0.0 (breaking change)

Update CHANGELOG.md with a summary of what changed.
Validate the theme files are well-formed:
```
npm run validate:themes
```
Package the extension:
```
npx vsce package
```
This produces a .vsix file (e.g. esacteksab-kai-0.0.6.vsix).

Test the package by installing it locally:

code --install-extension esacteksab-kai-<version>.vsix

Commit and push — the Validate Extension CI workflow will verify the package builds cleanly on every push and PR.
