f5-troubleshoot

f5-troubleshoot is a skill for Claude Code from automateyournetwork/netclaw. It costs 72 tokens per session (7,028 once invoked), scanned A, original, Apache-2.0.

A troubleshooting tool for F5 BIG-IP, a system that directs application traffic to backend servers. It examines virtual servers, server pools, logs, live statistics, SSL/TLS settings, persistence, and iRule errors.

In plain words
What is it for?
Use it to diagnose virtual server failures, pool member health problems, connection issues, SSL/TLS errors, iRule errors, persistence problems, and performance degradation.
Why use it?
It gives a structured way to investigate why an application is unavailable, slow, showing certificate errors, or sending traffic to unhealthy servers. It encourages checking evidence and verifying each change.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

f5-troubleshoot 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 9d ago.

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.

F5 BIG-IP Troubleshooting

Troubleshooting Principles

  1. Define the problem -- What exactly is broken? Who reported it? What is the expected vs actual behavior?
  2. Gather facts -- List objects, check stats, read logs. Never assume.
  3. Consider possibilities -- Based on facts, list likely root causes
  4. Create action plan -- Test one variable at a time
  5. Implement and verify -- Make one change, verify, document
  6. Document -- Record what was found and what fixed it

How to Call the Tools

The F5 MCP server provides 6 tools. Call them via mcp-call with the required environment variables:

IP_ADDRESS=$F5_IP_ADDRESS Authorization_string=$F5_AUTH_STRING python3 $MCP_CALL "python3 -u $F5_MCP_SCRIPT" <tool_name> '{"param":"value"}'

Available Tools for Troubleshooting

Tool Purpose When to Use
list_tool List and inspect object configuration Verify config is correct
show_stats_tool Show live statistics and counters Identify traffic flow issues
show_logs_tool Show system logs Find errors and event correlation
update_tool Modify object configuration Apply fixes
create_tool Create new objects Add missing objects
delete_tool Remove objects Remove problematic objects

Symptom: "Virtual Server Not Responding to Clients"

Clients report they cannot connect to the application VIP.

Step 1: Verify Virtual Server Exists and Is Enabled

IP_ADDRESS=$F5_IP_ADDRESS Authorization_string=$F5_AUTH_STRING python3 $MCP_CALL "python3 -u $F5_MCP_SCRIPT" list_tool '{"object_name":"vs_webapp_https","object_type":"virtual"}'

Check:

  • Does the virtual server exist? If not, it was deleted or never created.
  • Is it enabled: true? If disabled, someone took it out of service.
  • Is the destination (VIP:port) correct?
  • Is a pool assigned?
  • Is sourceAddressTranslation configured? (Without SNAT/automap, return traffic may bypass the BIG-IP.)

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.
