package.json:28

• package.json declares engines.node: ">=20", but the updated dependency tree requires a higher minimum Node version (e.g. inquirer@13.4.2 in pnpm-lock.yaml requires Node ^20.12.0 and esbuild-plugin-browserslist@2.0.0 requires ^20.19.0). Consider bumping engines.node to at least >=20.19.0 to avoid installs failing or emitting engine warnings on older Node 20 minors.

The new Playwright tests path is added as ./wiki/tiddlers/tests/playwright/*.ts, which only matches files directly under that folder. If tests are organized into subfolders (and the workflow uses **/*.ts), ESLint's projectService may not pick them up; consider switching this glob to ./wiki/tiddlers/tests/playwright/**/*.ts.

Suggested change

Lint Code is marked continue-on-error: true, so the workflow can report success even when linting fails. If this workflow is meant to validate PRs, consider removing continue-on-error (or gating it behind an input) so lint failures correctly fail the check.

Suggested change

continue-on-error: true

This workflow posts a new PR comment on every run for both success and failure, which can quickly spam PR threads on frequent pushes. Consider removing these steps or switching to a "sticky" comment/update pattern (or relying on GitHub Checks / job summaries) to avoid repeated comments.

After removing the pnpm.overrides pin and bumping tiddlywiki-plugin-dev, the lockfile now resolves esbuild-plugin-browserslist@2.0.0 which declares a peer dependency on esbuild ~0.27.0, but the lockfile also resolves esbuild@0.28.0. Even with strict-peer-dependencies=false, this peer mismatch can cause subtle build issues; consider aligning versions (pin esbuild to 0.27.x, add an override, or bump to a plugin version that supports 0.28.x).
