Claude Code Guide is a reference collection for configuring and using Claude Code, Anthropic’s command-line coding agent. Developers use it to learn commands, skills, agents, MCP, automation, security, integrations, and troubleshooting. Its catalogue add-ons provide many of the documented skills and agents.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00079 | $0.02722 |
| Opus 5 | $0.00039 | $0.01361 |
| Sonnet 5 | $0.00016 | $0.00544 |
| Haiku 4.5 | $0.00008 | $0.00272 |
Grade A, and why
wireshark-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 498 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wireshark Network Traffic Analysis
Purpose
Execute comprehensive network traffic analysis using Wireshark to capture, filter, and examine network packets for security investigations, performance optimization, and troubleshooting. This skill enables systematic analysis of network protocols, detection of anomalies, and reconstruction of network conversations from PCAP files.
Inputs / Prerequisites
Required Tools
- Wireshark installed (Windows, macOS, or Linux)
- Network interface with capture permissions
- PCAP/PCAPNG files for offline analysis
- Administrator/root privileges for live capture
Technical Requirements
- Understanding of network protocols (TCP, UDP, HTTP, DNS)
- Familiarity with IP addressing and ports
- Knowledge of OSI model layers
- Understanding of common attack patterns
Use Cases
- Network troubleshooting and connectivity issues
- Security incident investigation
- Malware traffic analysis
- Performance monitoring and optimization
- Protocol learning and education
Outputs / Deliverables
Primary Outputs
- Filtered packet captures for specific traffic
- Reconstructed communication streams
- Traffic statistics and visualizations
- Evidence documentation for incidents
Core Workflow
Phase 1: Capturing Network Traffic
Start Live Capture
Begin capturing packets on network interface:
1. Launch Wireshark
2. Select network interface from main screen
3. Click shark fin icon or double-click interface
4. Capture begins immediately
Capture Controls
| Action | Shortcut | Description |
|---|---|---|
| Start/Stop Capture | Ctrl+E | Toggle capture on/off |
| Restart Capture | Ctrl+R | Stop and start new capture |
| Open PCAP File | Ctrl+O | Load existing capture file |
| Save Capture | Ctrl+S | Save current capture |
Capture Filters
Apply filters before capture to limit data collection:
# Capture only specific host
host 192.168.1.100
# Capture specific port
port 80
# Capture specific network
net 192.168.1.0/24
# Exclude specific traffic
not arp
# Combine filters
host 192.168.1.100 and port 443
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

wireshark-analysis is a skill published in the GitHub repository zebbern/claude-code-guide (4,600 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 2,722 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
