+# OpenCode Superpowers Overview Implementation Plan
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add one new blog post that summarizes `obra/superpowers` (OpenCode-first) + update the AI/OpenCode sidebar entry, matching this blog's writing style.
+
+**Architecture:** One new Markdown article under `src/ai/` plus a small ordering update in `src/.vuepress/sidebar.ts`. Use upstream README as the source-of-truth for workflow + install commands.
+
+**Tech Stack:** VuePress v2 + vuepress-theme-hope, Markdown, TypeScript config.
+
+---
+
+### Task 1: Gather upstream command strings + permalinks
+
+**Files:**
+- Read: `~/.config/opencode/superpowers/README.md`
+
+- [ ] **Step 1: Get upstream repo HEAD SHA (for permalinks)**
+
+Run:
+
+```bash
+git -C "$HOME/.config/opencode/superpowers" rev-parse HEAD
+```
+
+Expected: prints a 40-char SHA.
+
+- [ ] **Step 2: Identify exact upstream snippets to copy**
+
+From upstream `README.md`:
+
+- Installation commands (Claude Code official + marketplace, Cursor, Codex, OpenCode, Gemini)
+- Update command (Claude Code)
+- Verify Installation paragraph
+- Basic Workflow list
+
+---
+
+### Task 2: Create the new overview post
+
+**Files:**
+- Create: `src/ai/opencode-superpowers-overview.md`
+
+- [ ] **Step 1: Add frontmatter + title + `<!-- more -->`**
+
+Requirements:
+
+- Chinese
+- Major headings `## 一、二、三...`
+- Use `---` thematic breaks between major sections
+
+- [ ] **Step 2: Add sections per spec**
+
+Include:
+
+- What it is (1 screen)
+- Upstream Basic Workflow (7 steps; step 4 includes "subagent-driven-development or executing-plans")
+- Skill map (if/then) + links to existing posts:
+  - `src/ai/opencode-superpowers.md`
+  - `src/ai/opencode-skills-playbook.md`
+- Install/Verify/Update quick reference with strict fenced-block counts:
+  - 5 install blocks (Claude/Cursor/Codex/OpenCode/Gemini)
+  - 1 verify block (2 lines)
+  - 3 update blocks (Claude/OpenCode/Gemini)
+  - Cursor + Codex updates as plain text notes (no fenced blocks)
+
+---
+
+### Task 3: Update sidebar order
+
+**Files:**
+- Modify: `src/.vuepress/sidebar.ts`
+
+- [ ] **Step 1: Insert new link under AI -> OpenCode**
+
+Insert before the existing:
+
+- `text: "superpowers"`
+- `link: "opencode-superpowers.md"`
+
+New item:
+
+- `text: "superpowers-总览"`
+- `link: "opencode-superpowers-overview.md"`
+
+Ensure final order:
+
+1) `opencode.md`
+2) `opencode-tui.md`
+3) `opencode-superpowers-overview.md`
+4) `opencode-superpowers.md`
+5) `opencode-skills-playbook.md`
+
+---
+
+### Task 4: Verify build
+
+**Files:**
+- None
+
+- [ ] **Step 1: Run production build**
+
+Run:
+
+```bash
+npm run docs:build
+```
+
+Expected: `success VuePress build completed`.
