feat: force Claude to read all issue comments via MCP tools

Update issue handler to ensure Claude reads complete discussion context:
- Modified prompt to instruct Claude to use mcp__gogs__get_issue and mcp__gogs__list_issue_comments
- Added explicit step-by-step instructions forcing comment reading before work
- Changed to non-interactive mode (--print --dangerously-skip-permissions)
- Prevents Claude from missing important context in issue discussions

Added comprehensive documentation and test utilities:
- docs/CLAUDE-AUTOMATION.md: Complete automation workflow guide
- scripts/test-claude-noninteractive.sh: Verify non-interactive execution
- show-example-prompts.sh: Demo generated prompts

This ensures Claude always has full conversation context before taking action.

+# Claude Code Automation Guide
+
+## Overview
+
+This document explains how Claude Code runs automatically in response to Gogs webhook events (issues and comments).
+
+## Architecture
+
+### How It Works
+
+```
+1. Gogs Webhook → HTTP Server (accepts immediately, returns 200)
+                      ↓
+2. Webhook Handler → Enqueues job (non-blocking)
+                      ↓
+3. Job Queue → Processes ONE job at a time (FIFO)
+                      ↓
+4. Command Executor → Runs handle-issue.sh (BLOCKS queue)
+                      ↓
+5. Claude Code → Runs non-interactively (completes task)
+                      ↓
+6. Job Complete → Next job starts
+```
+
+### Key Components
+
+#### 1. Webhook Server (`src/server.js`)
+- Listens on `http://0.0.0.0:3000/webhook`
+- Accepts webhooks immediately (no blocking)
+- Returns HTTP 200 instantly
+
+#### 2. Job Queue (`src/jobQueue.js`)
+- **FIFO Processing**: Jobs execute in order received
+- **Sequential Execution**: Only ONE job runs at a time
+- **Queue Blocks**: Next job waits until current one finishes
+- **Persistence**: Queue state saved to `queue.json`
+- **Crash Recovery**: Pending jobs resume after restart
+
+#### 3. Issue Handler Script (`scripts/handle-issue.sh`)
+- Checks if issue is assigned to `claude` user
+- Clones/updates repository
+- Builds prompt instructing Claude to fetch all comments
+- Runs Claude Code non-interactively
+
+#### 4. Claude Code
+- Runs with `--print --dangerously-skip-permissions`
+- **Uses Gogs MCP tools to fetch issue and all comments**
+- **Reads entire discussion history before starting work**
+- No user interaction required
+- Completes task and exits
+
+## Configuration
+
+### Enable Issue & Comment Webhooks
+
+**.env:**
+```bash
+# Issues Event Configuration
+WEBHOOK_ISSUES_ENABLED=true
+
+# Issue Comment Event Configuration
+WEBHOOK_ISSUE_COMMENT_ENABLED=true
+```
+
+### Command Configuration
+
+**commands.json:**
+```json
+{
+  "commands": {
+    "issues": [
+      {
+        "name": "claude-issue-handler",
+        "description": "Automatically handle issues assigned to Claude",
+        "type": "shell",
+        "command": "/home/claude/agent-manager/scripts/handle-issue.sh",
+        "args": [
+          "{{repo_owner}}",
+          "{{repo}}",
+          "{{pusher}}",
+          "{{issue_number}}",
+          "{{issue_title}}",
+          "{{issue_body}}",
+          "{{issue_action}}",
+          "",
+          "{{issue_assignee}}"
+        ],
+        "cwd": null,
+        "timeout": 600000,
+        "filterBranch": null
+      }
+    ],
+    "issue_comment": [
+      {
+        "name": "claude-comment-handler",
+        "description": "Handle issue comments for Claude-assigned issues",
+        "type": "shell",
+        "command": "/home/claude/agent-manager/scripts/handle-issue.sh",
+        "args": [
+          "{{repo_owner}}",
+          "{{repo}}",
+          "{{pusher}}",
+          "{{issue_number}}",
+          "{{issue_title}}",
+          "{{issue_body}}",
+          "{{issue_action}}",
+          "{{comment_body}}",
+          "{{issue_assignee}}"
+        ],
+        "cwd": null,
+        "timeout": 600000,
+        "filterBranch": null
+      }
+    ]
+  }
+}
+```
+
+## Critical Flags for Non-Interactive Claude
+
+### Problem
+By default, Claude Code runs in **interactive mode** and expects:
+- Terminal (TTY) for UI
+- User to approve permissions
+- User to confirm actions
+
+When run from a script, Claude would **hang waiting for input**.
+
+### Solution
+Use these flags to run Claude non-interactively:
+
+```bash
+claude --print --dangerously-skip-permissions "$PROMPT"
+```
+
+**Flags explained:**
+- `--print`: Non-interactive mode - print output and exit
+- `--dangerously-skip-permissions`: Skip all permission dialogs (safe in controlled environment)
+
+**Alternative (safer in some contexts):**
+```bash
+claude --print --permission-mode bypassPermissions "$PROMPT"
+```
+
+## Behavior
+
+### ✅ What Happens
+
+1. **Multiple webhooks arrive quickly:**
+   - All are accepted immediately (HTTP 200)
+   - All are queued
+
+2. **Queue processes sequentially:**
+   - Job 1 starts → Claude runs → Claude finishes → Job 1 complete
+   - Job 2 starts → Claude runs → Claude finishes → Job 2 complete
+   - Job 3 starts → ...
+
+3. **New webhooks accepted during processing:**
+   - Webhook arrives while Claude is running
+   - Gets queued immediately
+   - Webhook sender gets instant 200 response
+   - Job will process when queue reaches it
+
+### ✅ Benefits
+
+- **No Lost Webhooks**: Even if Claude takes 30 minutes, new webhooks are queued
+- **No Concurrent Execution**: Only one Claude runs at a time (prevents conflicts)
+- **Crash Recovery**: If server crashes, pending jobs resume on restart
+- **No Timeouts**: Webhook sender gets instant response, doesn't timeout
+
+## How Claude Reads All Comments
+
+### Critical Feature: Mandatory Comment Reading
+
+The system **forces Claude to read all issue comments** before starting work. This is achieved through:
+
+1. **Explicit Instructions in Prompt**
+   - Prompt contains step-by-step mandatory instructions
+   - Claude MUST use MCP tools to fetch data
+   - Clear order: fetch → read → understand → act
+
+2. **Gogs MCP Tools Used**
+   - `mcp__gogs__get_issue` - Fetches complete issue details
+   - `mcp__gogs__list_issue_comments` - Fetches ALL comments chronologically
+
+3. **Why This Matters**
+   - Prevents Claude from missing context
+   - Ensures Claude sees user clarifications
+   - Avoids duplicate work or wrong assumptions
+   - Claude understands full conversation history
+
+### Example Prompt Structure
+
+When an issue or comment is received, Claude gets this prompt:
+
+```
+IMPORTANT: Issue #42 was opened in repository owner/repo.
+
+=== MANDATORY FIRST STEPS - READ ALL MESSAGES ===
+
+Before you start any work on this issue, you MUST complete these steps IN ORDER:
+
+1. Use the mcp__gogs__get_issue tool to fetch the complete issue details:
+   - owner: owner
+   - repo: repo
+   - number: 42
+
+2. Use the mcp__gogs__list_issue_comments tool to fetch ALL comments:
+   - owner: owner
+   - repo: repo
+   - number: 42
+
+3. Read and understand:
+   - The complete issue description
+   - ALL comments in the discussion thread
+   - The full context
+
+4. ONLY AFTER reading everything above, proceed with your work
+
+=== ISSUE CONTEXT ===
+[Issue details here]
+
+=== YOUR TASK ===
+[Instructions here]
+
+DO NOT skip reading the comments using the MCP tools. This is critical.
+```
+
+This ensures Claude always has the complete conversation context.
+
+## Workflow Example
+
+### Scenario: User creates issue assigned to Claude
+
+1. **User creates issue** in Gogs
+   - Title: "Add dark mode to settings"
+   - Assignee: `claude`
+
+2. **Gogs sends webhook** → `POST /webhook`
+   - Event: `issues`
+   - Action: `opened`
+
+3. **Server accepts webhook** → Returns `200 OK` (instant)
+
+4. **Job enqueued:**
+   ```json
+   {
+     "id": 5,
+     "eventType": "issues",
+     "status": "pending",
+     "config": { "command": "handle-issue.sh", ... }
+   }
+   ```
+
+5. **Queue starts processing:**
+   - Runs `handle-issue.sh`
+   - Script clones/updates repo
+   - Builds prompt:
+     ```
+     Issue #5 was opened in owner/repo by user.
+
+     Issue Title: Add dark mode to settings
+
+     Issue Description: [description here]
+
+     This issue is assigned to you. Please review and handle it accordingly.
+     ```
+
+6. **Claude Code runs:**
+   ```bash
+   claude --print --dangerously-skip-permissions "$PROMPT"
+   ```
+   - **First**: Uses `mcp__gogs__get_issue` to fetch issue details
+   - **Second**: Uses `mcp__gogs__list_issue_comments` to fetch ALL comments
+   - **Third**: Reads and understands the complete discussion thread
+   - **Then**: Analyzes the requirements from full context
+   - Reads codebase
+   - Implements feature
+   - Commits changes
+   - Uses `mcp__gogs__create_issue_comment` to comment on issue
+
+7. **Job completes** → Next job starts (if any)
+
+## Testing
+
+### Test Non-Interactive Mode
+
+```bash
+./scripts/test-claude-noninteractive.sh
+```
+
+Expected output:
+```
+✓ SUCCESS: Claude ran non-interactively
+```
+
+### Test Queue Blocking
+
+Send multiple webhooks rapidly:
+```bash
+./test-queue-blocking.sh
+```
+
+Monitor queue:
+```bash
+watch -n1 'cat queue.json | jq .queue'
+```
+
+You should see:
+- All jobs queued immediately
+- Only one job with `status: "running"`
+- Others with `status: "pending"`
+- Jobs complete one by one
+
+## Monitoring
+
+### Check Queue Status
+
+```bash
+cat queue.json | jq
+```
+
+### Watch Queue in Real-Time
+
+```bash
+watch -n1 'cat queue.json | jq .queue'
+```
+
+### View Server Logs
+
+```bash
+# If running with systemd
+journalctl -u agent-manager -f -n100
+
+# If running with npm run dev
+# Check terminal where server is running
+```
+
+## Troubleshooting
+
+### Claude hangs/does nothing
+
+**Problem:** Claude is waiting for user input
+
+**Solution:** Ensure you're using `--print` and `--dangerously-skip-permissions` flags
+
+### Jobs pile up in queue
+
+**Problem:** Jobs are being queued but not processing
+
+**Solution:**
+1. Check if a job is stuck running: `cat queue.json | jq '.queue[] | select(.status=="running")'`
+2. Check server logs for errors
+3. Restart server to reset stuck jobs to pending
+
+### Webhooks timing out
+
+**Problem:** Gogs webhook delivery fails with timeout
+
+**Solution:** This shouldn't happen - webhooks return immediately. Check:
+1. Is server running? `curl http://localhost:3000/health`
+2. Check firewall/network
+3. Verify webhook URL in Gogs settings
+
+### Claude makes no changes
+
+**Problem:** Claude runs but doesn't commit anything
+
+**Solution:**
+1. Check if issue is assigned to `claude` user
+2. Verify repository exists and Claude has access
+3. Check the prompt being sent to Claude
+4. Review Claude's output in logs
+
+## Security Considerations
+
+### `--dangerously-skip-permissions` Flag
+
+This flag bypasses all permission checks. It's **safe in this context** because:
+- ✅ Claude only runs on issues assigned to `claude` user
+- ✅ Runs in isolated environment
+- ✅ Repository is controlled/trusted
+- ✅ No external network access to malicious sites
+
+**Do NOT use** if:
+- ❌ Untrusted users can trigger Claude
+- ❌ Claude has access to production systems
+- ❌ Running on sensitive data
+
+### Alternative Safer Approach
+
+If you need more control, use permission modes:
+```bash
+claude --print --permission-mode acceptEdits "$PROMPT"
+```
+
+This auto-accepts edits but may still prompt for other actions.
+
+## Advanced: Adding Logging
+
+To track Claude's output, modify the script:
+
+```bash
+# Create logs directory
+mkdir -p "$HOME/agent-manager/logs"
+
+# Log file with timestamp
+LOG_FILE="$HOME/agent-manager/logs/issue${ISSUE_NUMBER}_$(date +%Y%m%d_%H%M%S).log"
+
+# Run Claude with logging
+claude --print --dangerously-skip-permissions "$PROMPT" 2>&1 | tee "$LOG_FILE"
+```
+
+## Performance
+
+Typical execution times:
+- Webhook acceptance: < 100ms
+- Simple issue (read/comment): 10-30 seconds
+- Complex issue (code changes): 2-5 minutes
+- Very complex (multiple files): 5-15 minutes
+
+Queue handles bursts:
+- 10 webhooks → queued in ~1 second
+- Processing time: 10 × average job time
+- No webhook delivery failures
