refactor: 合并 claude-marketplace，重构目录结构为单一仓库

- 重命名 plugins/ → skills/，个人插件迁移到 skills-personal/（gitignore）
- 更新 generate-marketplace.py 支持 config 读取和 skills-personal 扫描
- 新增 claude-config.yaml（技能启用/禁用 + MCP 配置）
- 新增 init.sh（交互式 MCP 初始化，支持 stdio/SSE 模式）
- 新增 CLAUDE.md 项目说明
- 重写 README.md 反映新结构
- 删除过时脚本：PUSH.sh、generate-marketplace.sh、convert-skills.sh

+name: executing-plans
+description: Use when you have a written implementation plan to execute in a separate session with review checkpoints
+---
+
+# Executing Plans
+
+## Overview
+
+Load plan, review critically, create branch, execute tasks in batches, report for review between batches.
+
+**Core principle:** Batch execution with checkpoints for architect review.
+
+**Announce at start:** "I'm using the executing-plans skill to implement this plan."
+
+## The Process
+
+### Step 1: Load and Review Plan
+1. Read plan file
+2. Review critically - identify any questions or concerns about the plan
+3. If concerns: Raise them with your human partner before starting
+4. If no concerns: Proceed to branch setup
+
+### Step 2: Setup Branch
+**Before any implementation, ensure proper branch isolation.**
+
+1. Check if already on a feature branch for this task
+2. If not, use `/pr start` to create one:
+   ```bash
+   /pr start <type> <REQ-id> <name>
+   # Example: /pr start feature REQ-123 user-login
+   ```
+3. If no REQ-id available, ask user or create branch manually:
+   ```bash
+   git fetch origin
+   git checkout -b <type>/<descriptive-name> origin/main
+   ```
+4. Confirm branch is ready before proceeding
+
+**Branch types:** `feature`, `fix`, `refactor`
+
+### Step 3: Create Tasks and Execute Batch
+**Default: First 3 tasks**
+
+1. Create TodoWrite tasks from plan
+2. For each task in batch:
+   - Mark as in_progress
+   - Follow each step exactly (plan has bite-sized steps)
+   - Run verifications as specified
+   - Mark as completed
+
+### Step 4: Report
+When batch complete:
+- Show what was implemented
+- Show verification output
+- Say: "Ready for feedback."
+
+### Step 5: Continue
+Based on feedback:
+- Apply changes if needed
+- Execute next batch
+- Repeat until complete
+
+### Step 6: Complete Development
+
+After all tasks complete and verified:
+- Announce: "I'm using the finishing-a-development-branch skill to complete this work."
+- **REQUIRED SUB-SKILL:** Use superpowers:finishing-a-development-branch
+- Follow that skill to verify tests, present options, execute choice
+
+## When to Stop and Ask for Help
+
+**STOP executing immediately when:**
+- Hit a blocker mid-batch (missing dependency, test fails, instruction unclear)
+- Plan has critical gaps preventing starting
+- You don't understand an instruction
+- Verification fails repeatedly
+
+**Ask for clarification rather than guessing.**
+
+## When to Revisit Earlier Steps
+
+**Return to Review (Step 1) when:**
+- Partner updates the plan based on your feedback
+- Fundamental approach needs rethinking
+
+**Don't force through blockers** - stop and ask.
+
+## Remember
+- Review plan critically first
+- **Create feature branch before implementation**
+- Follow plan steps exactly
+- Don't skip verifications
+- Reference skills when plan says to
+- Between batches: just report and wait
+- Stop when blocked, don't guess
