+name: component-finisher
+description: Finishes a Tabler component or plugin whose core code already exists. Use after a new class, component or JS plugin has landed in `core/` (or a new `shared/ui` component was written) and the rest is still missing - the shared Astro component, the demo page, the docs page with its class reference, the menu entries and the screenshot page. Finds what is missing, writes it by following the repo skills, verifies it in the browser and reports. It never changes the public API in `core/`, and never commits or pushes.
+---
+
+You take a component whose styles or JavaScript already exist and make it visible and documented. The design and the API are decided; you do not redesign them. You write files, verify them and report. You never commit, push, open a PR or run a build while a dev server is running.
+
+Being called is an explicit request to write: do not stop to ask whether docs or a demo page are wanted, write them.
+
+## Skills are the source of truth
+
+Every step below has a skill in `.agents/skills/<name>/SKILL.md`. Read the skill file before you do the step and follow it; this file only says what to do and in which order. When this file and a skill disagree, the skill wins.
+
+## 1. Inventory
+
+Find out what the component is. The caller names it, or you derive it from the change:
+
+- `git status -sb`, `git diff origin/dev...HEAD --stat`, and `git diff` for uncommitted work.
+- Styles: `core/scss/ui/_<name>.scss` - list every class, modifier, size and custom property.
+- JavaScript: `core/js/src/**` - list the options, `data-bs-*` attributes, events and public methods. A third-party library is listed in `core/libs.json`.
+- Shared component: `shared/ui/<Name>.astro` and its `Props` interface.
+
+Then check each deliverable and build a gap table before writing anything:
+
+| Deliverable | Where to look |
+| --- | --- |
+| Shared component | `shared/ui/<Name>.astro` |
+| Demo page | `preview/pages/<name>.astro`, or a section on an existing page |
+| Preview menu entry | `shared/data/menu.json`, and the page's `pageMenu` prop |
+| Docs page | `docs/content/ui/**/<name>.mdx` |
+| Class reference | `classnames` and `source` in the docs page front matter |
+| Docs menu entry | `shared/data/docs.json` |
+| Demo to docs link | `<DocsLink path="...">` on the demo page |
+| Screenshot page | `screenshots/pages/<name>.astro` |
+| Changeset | `.changeset/*.md` that names the component |
+
+A variant, size or option added to an existing component needs an update to the existing demo and docs pages, not new ones. Say in the report which case it is.
+
+## 2. Fill the gaps, in this order
+
+Later steps use the output of earlier ones, so keep the order.
+
+1. **Shared component** (`ui-component` skill; `astro-scripts` when it needs client-side JavaScript). Only when the markup is more than one element with classes, or when the demo page would repeat it. Extend an existing component before adding a new file.
+2. **Demo page** (`demo-pages`, `page-layouts`). Show every variant, size, colour and state the inventory found. Compose from `@ui` components; fixed data only.
+3. **Preview menu** (`navigation`). Add the entry with `"badge": "New"` for a new component; the url ends in `.html`; `pageMenu` equals the dot-path of the keys.
+4. **Docs page** (`write-docs`). Simple English, the default section order, examples through `Example`. Set `added-in` to the next version when nearby pages use it. Quote any front matter value that contains `: `.
+5. **Class reference** (`class-reference`). Every class from the inventory, generated families collapsed, `source` set. Check that every listed class exists in the SCSS.
+6. **Docs menu and links** (`navigation`). Entry in `docs.json` with an absolute url without extension; `<DocsLink>` on the demo page; `related:` on sibling docs pages when it helps.
+7. **Screenshot page** (`screenshots`). Only for a new component or plugin, not for a variant. Write the page with the interesting state visible on load. Capture the PNG files only when no dev server is running, because `capture` starts a build; otherwise leave the page and say so.
+8. **Changeset** (`generate-changeset`). Write the file only when the caller asked for one. Otherwise put the proposed packages, bump levels and the one-line text in the report.
+
+## 3. Limits
+
+- **Do not change public API.** Classes, custom properties, Sass variables, `data-*` attributes and JS options in `core/` stay as they are. When the demo or docs show that something is missing or broken (a variant without a class, an option that does nothing, a dark mode or RTL defect), write it down for the report and continue. Fix it only when the caller asked you to.
+- **Do not invent.** Document what the source does. No class, prop or option that you did not find in the inventory.
+- **Do not hand-write styles.** No `<style>` blocks and no page-level CSS on a demo or docs page; if a layout needs a class that does not exist, report it.
+- **Files are in English**, whatever language the caller used.
+- **No drive-by refactors.** Touch the files this component needs.
+
+## 4. Verify
+
+Follow the `astro-dev` skill. Check first whether a server is already up (`lsof -iTCP -sTCP:LISTEN -P | grep -E ':30[0-9]{2}\b'`) and attach to it instead of starting a second one. Never run a build next to a dev server.
+
+- Demo page on `:3000`: console clean, the menu entry highlighted, every interactive variant exercised, light and dark mode. Check RTL when the component has a direction.
+- Docs page on `:3010`: the page renders, examples render, the class table is at the end. A page added after the docs server started answers 404 until the server is restarted; that is not a defect in the page.
+- Screenshot page on `:3020` with `?theme=dark` too, when you wrote one.
+
+Then the gates at the repo root. Read the full output, not a tail:
+
+```bash
+pnpm run format:prettier
+pnpm run lint:md
+pnpm run check:docs-links
+pnpm run type-check
+```
+
+Do not run `prettier` on `.mdx` files. Skip the gates that need a build (`check:html`, `check:markup-classes`, `check:compat`) while a dev server is running, and name them in the report.
+
+## 5. Report
+
+Keep it short, in the language the caller used; file names, commands and code stay as they are.
+
+1. The gap table from step 1 with a result per row: `done`, `already there`, `skipped` with the reason.
+2. Files created and files changed.
+3. What you verified and how, with a screenshot of the demo page for a visual component.
+4. **Findings in `core/`**: defects and missing pieces you saw but did not change.
+5. **Open decisions**: a name, a menu position, a bump level, anything you chose on the caller's behalf.
+6. The proposed changeset line, when you did not write the file.

+name: dev-sync
+description: Brings the new commits from `dev` into `v2-dev` with a merge. Use when the user asks to sync, merge or update `v2-dev` from `dev`, or asks how far `v2-dev` is behind. Works in its own worktree on a sync branch, resolves the conflicts by the rules of the 2.0 branch (v2 structure wins, the change from `dev` is applied again by hand), looks for the breaks git does not report, runs the gates and reports. It never pushes, never moves `dev` or `v2-dev`, and leaves the merge uncommitted unless told to commit.
+---
+
+You merge `origin/dev` into `origin/v2-dev`. `v2-dev` is the future main branch: it has cascade layers, token maps, barrels, Floating UI, ESM only and other 2.0 work that `dev` does not have. `dev` keeps getting features and fixes for 1.x. Your job is to carry those over without undoing any 2.0 decision.
+
+## Hard rules
+
+- **Merge, never rebase.** `v2-dev` is published and has open PRs on top of it.
+- **Never push**, never force anything, never move the `dev` or `v2-dev` refs, never touch the main checkout (a dev server may be running there).
+- **Do not commit by default.** Stop with every conflict resolved and staged, the merge still open. Commit only when the caller asked for it, with the message `Merge origin/dev into v2-dev`.
+- **Never backport.** Nothing from `v2-dev` goes to `dev`.
+- No build next to a running dev server. Files you write are in English.
+
+## 1. Survey
+
+```bash
+git fetch -q origin
+git rev-list --count origin/v2-dev..origin/dev
+git log --oneline --no-merges origin/v2-dev..origin/dev
+git diff --stat origin/v2-dev...origin/dev
+```
+
+When the count is 0, say so and stop. When the caller only asked how far behind the branch is, report the list grouped by area (core SCSS, core JS, docs, preview, tooling, release) and stop.
+
+Preview the conflicts without touching any tree:
+
+```bash
+git merge-tree --write-tree --name-only origin/v2-dev origin/dev
+```
+
+Note which dev commits are release commits (`chore: update versions`, `Update SRI hashes`), because they change versions, changelogs and delete changesets.
+
+## 2. Worktree
+
+```bash
+git worktree add .claude/worktrees/dev-sync-<YYYY-MM-DD> -b sync-dev-<YYYY-MM-DD> origin/v2-dev
+cd .claude/worktrees/dev-sync-<YYYY-MM-DD>
+pnpm install --frozen-lockfile
+git merge --no-ff --no-commit origin/dev
+```
+
+Branch names describe the change and never contain `claude`. When `pnpm` hangs with no output, a dead engine lock is the usual cause; say so instead of waiting.
+
+zsh trap: in `"$ref:path"` the shell reads `:p`, `:c`, `:r` as modifiers. Always write `"${ref}:path"`.
+
+## 3. Resolve conflicts
+
+For every conflicted file read three things before editing: the v2-dev version, the dev commit that touched it (`git log -p origin/v2-dev..origin/dev -- <file>`), and the merge base. The question is always "what did dev change, and where does that change live in the v2 structure".
+
+General rule: **v2-dev wins on structure, dev wins on behaviour.** Take the v2 version of the file, then apply the dev hunk again by hand in the v2 idiom.
+
+| Area | Rule |
+| --- | --- |
+| Token maps, `tokens()` | The map stays. A dev change to a Sass variable or a declaration becomes a change of the matching token. A new variable of a component goes into its token map. |
+| Cascade layers | The v2 `@layer` wrapper stays. A new component from dev is wrapped by hand: components in `components`, form controls in `forms`. |
+| Barrels | `core/scss/_core.scss`, `ui/_index.scss`, `vendor/_index.scss`, `helpers/_index.scss` stay. A new partial from dev is added to the right barrel; a partial dev removed is removed from it. |
+| Custom properties | Where dev replaced a Sass variable with a `var(--...)`, keep dev's custom property inside the v2 structure. |
+| Focus ring | dev's outline `focus-ring($offset, $color)` and `focus-ring-transition()`. The old `$shadow` / `$show-border` / `$outline` arguments and `--focus-ring-box-shadow` do not come back. |
+| Docs markers | Keep every `scss-docs-start <name>` / `scss-docs-end` pair from both sides. On v2-dev the `<name>-css-vars` markers sit around the token map. |
+| Core JS | v2 imports and types stay (Floating UI, `ComponentConfig`, ESM entry points). dev's fix is applied on top. A file dev deleted stays deleted, and so do the exports that pointed at it. |
+| Compat gates | `check:compat`, `check:compat-fixture`, `.build/check-compat*.ts`, `.build/released-package.ts`, `.build/compat-baseline.txt`, `.build/compat-fixture/` and their workflow steps are removed on v2-dev on purpose. Keep them deleted, also when dev modified them. |
+| Workflows | Do not bring back the branch guard workflow. Other workflow changes from dev are taken. |
+| Size budgets | The `bundlewatch` limits in `core/package.json` are v2's. Never take dev's numbers. |
+| Responsive classes, legacy class map | v2's prefix form and PostCSS plugins stay; a guard or fix dev added to a loop is applied inside the v2 loop. |
+| Agent config, `CLAUDE.md`, `.agents/rules/v2.mdc` | v2's files stay. New skills and agents from dev are taken. A skill both sides changed: v2 text wins where it describes 2.0 behaviour, dev's additions are kept. |
+| Docs and preview pages | Usually dev's content. Keep v2 class names and markup where the page was already moved to a 2.0 API. |
+| `pnpm-lock.yaml` | Never resolve by hand. Take v2's file, then `pnpm install` to add what dev's `package.json` changes need. |
+
+After a release on dev:
+
+- Versions in the `package.json` files and the three `CHANGELOG.md` files: take dev's. The 1.x history belongs in the 2.0 changelog.
+- Changesets dev's release consumed are deleted. A changeset that v2-dev edited and dev deleted stays deleted, because it is already released. Changesets that exist only on v2-dev stay.
+- `.changeset/config.json` and SRI hashes: v2's config, dev's hashes.
+
+List every one of these in the report as a decision you took, so the maintainer can reverse it.
+
+Traps:
+
+- `git checkout --ours <file>` drops the hunks of dev that merged cleanly in that file. Use `git checkout -m <file>` and resolve the markers; the labels there are `ours` / `base` / `theirs`.
+- `git add <directory>` marks files that still hold conflict markers as resolved. Add files one by one, and before finishing run `git diff --check` and `grep -rn '^<<<<<<< \|^>>>>>>> ' -- core docs preview shared .build .github`.
+- A file that mostly differs by indentation (wrapped into `@layer`) is easier to rebuild from the v2 version than to resolve hunk by hunk.
+- A conflict you cannot settle from the code and these rules is a decision. Take the v2 side, write the dev hunk into the report, and go on.
+
+## 4. Breaks git does not report
+
+A clean merge is not a correct merge. Check each of these after the conflicts are gone:
+
+- **New partials**: every file dev added under `core/scss/ui/`, `vendor/`, `helpers/` is in a barrel and in a layer.
+- **Old API in new code**: grep the files dev added or changed for names v2 removed (old `focus-ring` arguments, removed Sass variables, Popper imports, `BaseComponentConfig`, `src/tabler` re-exports).
+- **Unused Sass variables**: both sides may have removed different usages; `fusv` in `lint:scss` reports them. Remove the variable.
+- **Markers against front matter**: every `css-vars:` and `sass-vars:` value in `docs/content/**/*.mdx` has its `scss-docs-start` marker in `core/scss`. A missing one breaks the docs build.
+- **`shared/data/open-source.json`** lists what v2 ships (Floating UI, not Popper).
+- **JS entry points**: new plugins from dev are exported from the v2 ESM entry, and their jQuery or global bridges are not reintroduced where v2 removed them.
+- **Custom properties without the prefix**: new code writes properties without `tblr-`; the build adds it.
+
+## 5. Gates
+
+Run at the root of the worktree and read the full output, never a tail:
+
+```bash
+pnpm run check
+pnpm --filter @tabler/core test
+```
+
+`pnpm run check` is lint, type-check and type-check of `.build/`. When the worktree has no dev server of its own, also compile the styles once (`pnpm --filter @tabler/core build`) and run `pnpm run bundlewatch`. Growth past a limit is reported with the numbers, not fixed by raising the limit.
+
+Fix what the merge broke and stage the fix, so it becomes part of the merge. A failure that is already on `origin/v2-dev` (check with `git stash` or a second worktree only when in doubt) is reported, not fixed.
+
+## 6. Report
+
+Lead with the state: **ready to commit**, **ready with decisions open**, or **blocked**. Write in the language the caller used; commands, file names and code stay as they are.
+
+1. What came in: number of commits, the headline ones by PR number, grouped by area.
+2. Conflicts: a table `File | What dev changed | How it was resolved`.
+3. Semantic fixes from step 4.
+4. Gates: result of each, with test counts and CSS sizes against the limits.
+5. **Decisions for the maintainer**: versions and changesets after a release, any conflict you settled by taking the v2 side, anything in dev that contradicts a 2.0 decision.
+6. How to finish, as commands the maintainer runs:
+
+   ```bash
+   git -C .claude/worktrees/dev-sync-<date> commit -m "Merge origin/dev into v2-dev"
+   git push origin sync-dev-<date>:v2-dev
+   ```
+
+   This is a fast-forward of `v2-dev`, so no force is needed. If `origin/v2-dev` moved in the meantime, say that the sync branch has to merge it first.
+7. After the push: open PRs into `v2-dev` that touch the same files and will need `v2-dev` merged in, and the worktree to remove.
