feat: add awf-debug-tools skill with practical Python scripts

Add collection of practical Python debugging scripts that reduce output
noise by 80%+ and provide actionable insights for debugging awf firewall.

Scripts:
- parse-squid-logs.py: Parse Squid logs and extract blocked domains
- diagnose-awf.py: Automated diagnostic checks with actionable fixes
- inspect-containers.py: Concise container status without verbose output
- test-domain.py: Test if domain is reachable through firewall
- common.py: Shared utilities (log parsing, container ops, config reading)

Features:
- Zero dependencies (Python 3.8+ stdlib only)
- JSON output support for agent parsing
- Auto-discovery of logs from multiple sources
- Proper exit codes (0=success, 1=issues, 2=error)
- Comprehensive documentation in SKILL.md

All scripts tested and verified working with real awf runs.

+
+# AWF Debug Tools
+
+A collection of practical Python scripts that help agents efficiently debug and operate the awf firewall. These scripts reduce verbose Docker/log output by 80%+ and provide actionable insights instead of raw data dumps.
+
+## Why These Scripts?
+
+**Problem:** Docker commands and log files are verbose and hard for agents to parse. Diagnosing issues requires 10+ manual commands and produces noisy output that wastes tokens.
+
+**Solution:** One script replaces 5-10 manual commands with clean, filtered output optimized for agent consumption. All scripts support JSON format for easy parsing.
+
+## Available Scripts
+
+All scripts are located in `.claude/skills/awf-debug-tools/scripts/`:
+
+1. **parse-squid-logs.py** - Parse Squid logs and extract blocked domains with counts
+2. **diagnose-awf.py** - Run automated diagnostic checks on container health and configuration
+3. **inspect-containers.py** - Show concise container status without verbose docker output
+4. **test-domain.py** - Test if specific domain is reachable through the firewall
+
+## Quick Start
+
+### Parse Logs to Find Blocked Domains
+
+```bash
+# Auto-discover logs and show all domains
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py
+
+# Show only blocked domains
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --blocked-only
+
+# Filter by domain
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --domain github.com
+
+# Show top 10, JSON output
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --top 10 --format json
+```
+
+### Run Automated Diagnostics
+
+```bash
+# Quick health check
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py
+
+# Detailed output
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py --verbose
+
+# JSON output for agent parsing
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py --format json
+```
+
+### Inspect Container Status
+
+```bash
+# Inspect all containers
+python .claude/skills/awf-debug-tools/scripts/inspect-containers.py
+
+# Specific container only
+python .claude/skills/awf-debug-tools/scripts/inspect-containers.py --container awf-squid
+
+# Show only logs
+python .claude/skills/awf-debug-tools/scripts/inspect-containers.py --logs-only
+
+# JSON output
+python .claude/skills/awf-debug-tools/scripts/inspect-containers.py --format json
+```
+
+### Test Domain Reachability
+
+```bash
+# Test if domain is allowed
+python .claude/skills/awf-debug-tools/scripts/test-domain.py github.com
+
+# Test blocked domain with fix suggestion
+python .claude/skills/awf-debug-tools/scripts/test-domain.py npmjs.org --suggest-fix
+
+# Check allowlist only (no log lookup)
+python .claude/skills/awf-debug-tools/scripts/test-domain.py api.github.com --check-allowlist
+
+# JSON output
+python .claude/skills/awf-debug-tools/scripts/test-domain.py github.com --format json
+```
+
+## Common Workflows
+
+### Workflow 1: Debugging Blocked Requests
+
+When a command fails due to blocked domain:
+
+```bash
+# 1. Run diagnostics to check overall health
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py
+
+# 2. Parse logs to find which domains were blocked
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --blocked-only
+
+# 3. Test specific domain and get fix suggestion
+python .claude/skills/awf-debug-tools/scripts/test-domain.py npmjs.org --suggest-fix
+
+# 4. Apply the suggested fix
+sudo awf --allow-domains github.com,npmjs.org 'your-command'
+```
+
+### Workflow 2: Container Health Check
+
+When containers aren't starting or behaving unexpectedly:
+
+```bash
+# 1. Check container status and recent logs
+python .claude/skills/awf-debug-tools/scripts/inspect-containers.py
+
+# 2. Run full diagnostics
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py --verbose
+
+# 3. If issues found, check Squid logs for errors
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py
+```
+
+### Workflow 3: Agent Automated Debugging
+
+For agents to diagnose issues without human intervention:
+
+```bash
+# Run all checks with JSON output
+python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py --format json | jq .
+
+# Parse blocked domains
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --blocked-only --format json | jq .
+
+# Test each blocked domain
+python .claude/skills/awf-debug-tools/scripts/test-domain.py npmjs.org --format json | jq .
+```
+
+## Output Formats
+
+All scripts support two output formats:
+
+- **table/text** (default): Human-readable format with clear sections and alignment
+- **json**: Machine-readable format optimized for agent parsing
+
+Use `--format json` to get structured output that's easy to parse programmatically.
+
+## Exit Codes
+
+All scripts use consistent exit codes:
+
+- **0**: Success (no issues found, domain allowed, etc.)
+- **1**: Issues found (blocked domains, failed checks, domain blocked)
+- **2**: Error (missing logs, invalid arguments, etc.)
+
+## No Dependencies
+
+All scripts use Python 3.8+ stdlib only. No `pip install` required. They work out of the box on any system with Python 3.8+.
+

+- `diagnose-awf.py`: <3 seconds for all checks
+- `inspect-containers.py`: <2 seconds for both containers
+- `test-domain.py`: <1 second for domain check
+
+## Examples
+
+### Example 1: Find Blocked Domains
+
+```bash
+$ python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --blocked-only
+
+Blocked Domains (sorted by count):
+
+  Domain                  Blocked  Allowed  Total
+  =================================================
+  registry.npmjs.org      45       0        45
+  example.com             12       0        12
+
+Total requests: 1234
+Blocked: 57 (4.6%)
+Allowed: 1177 (95.4%)
+```
+
+### Example 2: Diagnose Issues
+
+```bash
+$ python .claude/skills/awf-debug-tools/scripts/diagnose-awf.py
+
+AWF Diagnostic Report
+========================================
+[✓] Containers: awf-squid (running), awf-agent (exited:0)
+[✓] Health: Squid healthy
+[✓] Network: awf-net exists ([{Subnet:172.30.0.0/24 Gateway:172.30.0.1}])
+[✓] Connectivity: Squid reachable on 172.30.0.10:3128
+[✓] DNS: DNS servers: 127.0.0.11, 8.8.8.8, 8.8.4.4
+[✓] Config: 3 domains in allowlist (github.com, .github.com, api.github.com)
+
+Summary: All checks passed ✓
+```
+
+### Example 3: Test Domain
+
+```bash
+$ python .claude/skills/awf-debug-tools/scripts/test-domain.py npmjs.org --suggest-fix
+
+Testing: npmjs.org
+
+[✗] Allowlist check: Not in allowlist
+[✗] Reachability: Blocked (403 TCP_DENIED:HIER_NONE)
+[✗] Status: BLOCKED
+
+Suggested fix:
+  awf --allow-domains github.com,npmjs.org 'your-command'
+```
+
+## Tips for Agents
+
+1. **Use JSON output** for easy parsing: `--format json | jq .`
+2. **Chain commands** to get complete picture: diagnose → parse logs → test domain
+3. **Check exit codes** to determine if action needed (0 = ok, 1 = issues)
+4. **Use --suggest-fix** to get ready-to-use awf commands
+5. **Scripts auto-discover logs** - no need to specify paths in most cases
+
+## Troubleshooting
+
+**Script not found:**
+```bash
+# Use absolute path
+python /home/mossaka/developer/gh-aw-repos/gh-aw-firewall/.claude/skills/awf-debug-tools/scripts/parse-squid-logs.py
+```
+
+**Permission denied on logs:**
+```bash
+# Squid logs require sudo to read
+sudo python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py --log-file /tmp/squid-logs-*/access.log
+```
+
+**No logs found:**
+```bash
+# Run awf first to generate logs
+sudo awf --allow-domains github.com 'curl https://api.github.com'
+
+# Then parse
+python .claude/skills/awf-debug-tools/scripts/parse-squid-logs.py
+```
+
+## Future Enhancements
+
+Planned scripts for future versions:
+- `analyze-traffic.py` - Analyze traffic patterns over time
+- `generate-allowlist.py` - Auto-generate allowlist from logs
+- `cleanup-awf.py` - Clean up orphaned resources
+- `benchmark-awf.py` - Performance testing utilities
