kepner-tregoe-network-troubleshooting

kepner-tregoe-network-troubleshooting is a skill for Claude Code from automateyournetwork/netclaw. It costs 197 tokens per session (2,516 once invoked), scanned A, original, Apache-2.0.

A structured method for diagnosing network faults and choosing corrective actions. It separates describing the problem, finding its verified cause, selecting a response, and protecting the change.

In plain words
What is it for?
Use it to investigate network failures, compare possible causes, triage several alarms, evaluate remediation choices, and plan changes safely.
Why use it?
It reduces guesswork during outages, alert storms, and performance problems by requiring evidence before a cause or fix is accepted.

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

kepner-tregoe-network-troubleshooting 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.

Kepner-Tregoe for Network Troubleshooting

What this skill is for

This skill gives a network-troubleshooting agent a disciplined method so it reaches a verified root cause before acting, instead of pattern-matching to a familiar cause and swapping components. The entire value is sequencing and separation: appraise before diagnosing, specify before theorizing, verify before fixing, decide before acting, protect before executing.

You will usually have tools that can read network state (telemetry, device configs, routing/ARP/session tables, logs, packet/flow data, inventory/CMDB). Use those tools to gather the evidence that fills the specification — do not reason from memory when you can observe. The method tells you which evidence matters and what to conclude from it.

Non-negotiable principles

  1. Specify before you hypothesize. Never name a cause until you have drawn the fault's boundary (what IS affected vs. what IS-NOT). The boundary is where the cause hides; skipping it is why troubleshooting drifts from symptom to symptom.
  2. The IS-NOT carries the answer. Recording what is broken eliminates almost nothing. Recording the nearest comparable thing that could be broken but isn't eliminates whole classes of cause in one line.
  3. Test every candidate cause against the whole specification. A cause that explains what IS but contradicts an IS-NOT is wrong, however plausible. Prefer the cause that fits with the fewest assumptions.
  4. Verify in the real world before you fix. A cause proven on paper is a hypothesis until a log line, a counter, a table entry, or a controlled test confirms it. Fixing an unverified cause "fixes" a symptom and leaves the root.
  5. Separate the incident fix from the permanent fix. Stop the bleeding with the fastest reversible known-good action; the proper fix is a separate, planned decision. Conflating them extends outages.
  6. Protect every change before executing it. Prevention + contingency with explicit triggers.
  7. Do not take state-changing actions without authorization. Diagnose and recommend freely. Before any config change, failover, reboot, or traffic-affecting action, confirm with the human/operator unless you have standing authorization for that specific action. Read-only investigation needs no confirmation.

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.
