+# Browser Inbox Create Link Conversion Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a Browser Inbox conversion workflow that creates an ordinary `.url` link file from a captured URL.
+
+**Architecture:** Keep conversion behavior in `verstak.browser-inbox`. The plugin writes a human-readable `.url` file through `api.files.writeText`, publishes `browser.capture.converted`, and leaves Activity/other consumers decoupled through the event bus.
+
+**Tech Stack:** Plain JavaScript official plugin bundle, Node smoke test harness, Markdown docs.
+
+## Global Constraints
+
+- Do not add a core link entity model in this slice.
+- Do not call private APIs from Browser Inbox.
+- Use only public plugin APIs: `api.files.writeText` and `api.events.publish`.
+- Do not silently rename on link path conflict; rely on `overwrite: false`.
+- Use TDD: write the failing smoke test first, run it red, then implement.
+
+---
+
+### Task 1: Browser Inbox Create Link Conversion
+
+**Files:**
+- Modify: `/home/mirivlad/git/verstak2/verstak-official-plugins/scripts/smoke-browser-inbox-plugin.js`
+- Modify: `/home/mirivlad/git/verstak2/verstak-official-plugins/plugins/browser-inbox/frontend/src/index.js`
+
+**Interfaces:**
+- Consumes:
+  - `api.files.writeText(relativePath, content, { createIfMissing: true, overwrite: false })`
+  - `api.events.publish('browser.capture.converted', payload)`
+- Produces:
+  - `Create Link` action for workspace-scoped URL captures.
+  - `browser.capture.converted` event with `conversionType: "link"`.
+
+- [ ] **Step 1: Write the failing smoke test**
+
+Add a scenario to `scripts/smoke-browser-inbox-plugin.js` that clicks
+`data-browser-inbox-action="create-link"` and asserts the written path,
+`.url` content, write options, queue removal, and published event.
+
+- [ ] **Step 2: Run RED**
+
+Run:
+
+```bash
+cd /home/mirivlad/git/verstak2/verstak-official-plugins
+PATH=/tmp/verstak2-tools:/home/mirivlad/.lmstudio/.internal/utils:$PATH node scripts/smoke-browser-inbox-plugin.js
+```
+
+Expected: fails because `Create Link` is not rendered.
+
+- [ ] **Step 3: Implement conversion**
+
+Add helpers in `plugins/browser-inbox/frontend/src/index.js`:
+
+- `safeLinkFilename(title)`;
+- `captureToUrlShortcut(capture)`;
+- `createLinkFromCapture(capture)`.
+
+Render a `Create Link` button for captures with `workspaceRootPath` and `url`.
+On success, remove the capture and publish `browser.capture.converted`.
+
+- [ ] **Step 4: Run GREEN**
+
+Run:
+
+```bash
+cd /home/mirivlad/git/verstak2/verstak-official-plugins
+PATH=/tmp/verstak2-tools:/home/mirivlad/.lmstudio/.internal/utils:$PATH node scripts/smoke-browser-inbox-plugin.js
+PATH=/tmp/verstak2-tools/venv/bin:/tmp/verstak2-tools:/home/mirivlad/.lmstudio/.internal/utils:$PATH ./scripts/check.sh
+```
+
+Expected: both commands exit 0.
+
+### Task 2: Roadmap Documentation
+
+**Files:**
+- Modify: `/home/mirivlad/git/verstak2/verstak-docs/05_Official_Plugins.md`
+- Modify: `/home/mirivlad/git/verstak2/verstak-docs/07_Full_Implementation_Roadmap.md`
+
+**Interfaces:**
+- Consumes verified create-link conversion behavior.
+- Produces docs that mark link file conversion done while leaving file attachment capture for later.
+
+- [ ] **Step 1: Update docs**
+
+Describe Browser Inbox create-link conversion through the public Files API and
+mark link conversion as complete.
+
+- [ ] **Step 2: Verify docs**
+
+Run:
+
+```bash
+cd /home/mirivlad/git/verstak2/verstak-docs
+git diff --check
+rg -n "Create Link|link conversion|file attachment|browser.capture.converted" 05_Official_Plugins.md 07_Full_Implementation_Roadmap.md
+```
+
+Expected: `git diff --check` exits 0 and `rg` shows updated status lines.

+# Browser Inbox Create Link Conversion Design
+
+## Purpose
+
+Browser captures should be convertible into a lightweight link artifact without
+forcing every URL into Notes. This slice adds a public Files API conversion that
+creates an ordinary human-readable `.url` file in the workspace.
+
+## Scope
+
+This slice adds one conversion action inside `verstak.browser-inbox`:
+
+- render `Create Link` for captures that have both `workspaceRootPath` and a
+  URL;
+- write a `.url` shortcut file to `<workspaceRootPath>/Links/<safe-title>.url`
+  through `api.files.writeText`;
+- publish `browser.capture.converted` with `conversionType: "link"`;
+- remove the converted capture from the inbox queue after a successful write;
+- leave the capture in place and show an error if the write fails.
+
+It does not add a core link entity model, a link resolver plugin, bulk
+conversion, or file attachment capture.
+
+## Link File Format
+
+The generated file is a plain text Internet shortcut:
+
+```ini
+[InternetShortcut]
+URL=https://example.com/article
+```
+
+The plugin writes with:
+
+```js
+api.files.writeText(linkPath, content, {
+  createIfMissing: true,
+  overwrite: false
+})
+```
+
+This preserves explicit conflict behavior. The plugin must not silently append a
+suffix when a link file already exists.
+
+## Event Contract
+
+After a successful conversion the plugin publishes:
+
+```js
+api.events.publish('browser.capture.converted', {
+  captureId,
+  conversionType: 'link',
+  linkPath,
+  workspaceRootPath,
+  title,
+  url,
+  sourcePluginId: 'verstak.browser-inbox'
+})
+```
+
+Activity can record this through the already-supported
+`browser.capture.converted` event.
+
+## Testing
+
+`scripts/smoke-browser-inbox-plugin.js` must prove:
+
+- a workspace capture with a URL renders `Create Link`;
+- clicking it writes the `.url` file through `api.files.writeText`;
+- the write uses `createIfMissing: true` and `overwrite: false`;
+- the capture is removed from its queue after success;
+- `browser.capture.converted` is published with `conversionType: "link"`;
+- when the write rejects, the capture remains in the queue and an error status
+  is rendered.
