+# RCON Password Display 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:** Show the RCON password on the server detail page with a show/hide toggle.
+
+**Architecture:** Three-file change. An external JS file (`password-reveal.js`) provides the reveal/hide interaction via event delegation on `[data-password-toggle]` attributes — no inline handlers or HTML event attributes. The template adds a row to the existing `.server-info` definition list with a masked span, value span, and toggle button. Base.html adds the script include alongside existing JS files.
+
+**Tech Stack:** Vanilla JS, Jinja2 templates, Flask
+
+---
+
+## File Structure
+
+| File | Responsibility |
+|------|---------------|
+| `l4d2web/static/js/password-reveal.js` | New. Delegated click listener for show/hide toggle on `[data-password-toggle]` |
+| `l4d2web/templates/server_detail.html` | Add one `<div>` row to `.server-info` DL |
+| `l4d2web/templates/base.html` | Add `<script src="...password-reveal.js">` |
+
+---
+
+### Task 1: Create the reveal/hide JS
+
+**Files:**
+- Create: `l4d2web/static/js/password-reveal.js`
+
+- [ ] **Step 1: Create `password-reveal.js`**
+
+```js
+document.addEventListener('click', (e) => {
+  const btn = e.target.closest('[data-password-toggle]');
+  if (!btn) return;
+  const id = btn.dataset.passwordToggle;
+  const mask = document.querySelector(`[data-password-field="${id}"].password-mask`);
+  const value = document.querySelector(`[data-password-field="${id}"].password-value`);
+  if (!mask || !value) return;
+  const hidden = value.hidden;
+  value.hidden = !hidden;
+  mask.hidden = hidden;
+  btn.textContent = hidden ? 'hide' : 'show';
+  btn.setAttribute('aria-label', hidden ? 'Hide RCON password' : 'Show RCON password');
+});
+```
+
+- [ ] **Step 2: Verify the file exists**
+
+Run: `ls -la l4d2web/static/js/password-reveal.js`
+Expected: File exists, is about 450 bytes
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add l4d2web/static/js/password-reveal.js
+git commit -m "feat: add password reveal toggle JS"
+```
+
+---
+
+### Task 2: Add RCON password row to server detail template
+
+**Files:**
+- Modify: `l4d2web/templates/server_detail.html:13`
+
+- [ ] **Step 1: Add the RCON password row after the blueprint row**
+
+Insert after line 13 (`</dd></div>` for blueprint):
+
+```html
+    <div><dt>RCON Password</dt><dd><span class="password-mask" data-password-field="{{ server.id }}">••••••••••••</span><span class="password-value" data-password-field="{{ server.id }}" hidden>{{ server.rcon_password }}</span> <button class="link-button" data-password-toggle="{{ server.id }}" aria-label="Show RCON password">show</button></dd></div>
+```
+
+Expected result: the `.server-info` DL now shows three rows: Port, Blueprint, RCON Password.
+
+- [ ] **Step 2: Verify template renders**
+
+Run: `python -c "from jinja2 import Environment; env=Environment(); env.parse(open('l4d2web/templates/server_detail.html').read()); print('parse ok')"`
+Expected: `parse ok`
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add l4d2web/templates/server_detail.html
+git commit -m "feat: add RCON password row to server detail page"
+```
+
+---
+
+### Task 3: Include the script in base template
+
+**Files:**
+- Modify: `l4d2web/templates/base.html:44`
+
+- [ ] **Step 1: Add the script include**
+
+Insert after line 43 (`<script src="...file-tree.js">`):
+
+```html
+    <script src="{{ url_for('static', filename='js/password-reveal.js') }}"></script>
+```
+
+Expected result: `base.html` now has 5 script includes: htmx, csrf.js, sse.js, modal.js, file-tree.js, password-reveal.js.
+
+- [ ] **Step 2: Verify the app starts**
+
+Run: `cd l4d2web && python -c "from l4d2web.app import create_app; app=create_app(); print('app created ok')"` (or similar smoke test)
+
+Expected: App initializes without import/template errors.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add l4d2web/templates/base.html
+git commit -m "feat: include password-reveal.js in base template"
+```
+
+---
+
+### Task 4: Run tests
+
+**Files:** None
+
+- [ ] **Step 1: Run existing test suite**
+
+Run: `pytest l4d2web/tests -q`
+Expected: All tests pass (no regressions from this purely-presentational change)
+
+- [ ] **Step 2: If any tests fail, investigate and fix**
+
+Run: `pytest l4d2web/tests -q --tb=long`
+Expected: Clear failure report to debug
