pyats-routing

pyats-routing is a skill for Claude Code from automateyournetwork/netclaw. It costs 70 tokens per session (2,927 once invoked), scanned A, original, Apache-2.0.

A network-routing analysis skill for examining how routers learn and forward traffic using protocols such as OSPF, BGP, EIGRP, and IS-IS.

In plain words
What is it for?
Use it to inspect routing tables, verify RIB and FIB entries, check protocol peers, audit route redistribution, and validate convergence.
Why use it?
It helps diagnose incorrect routes, broken routing neighbors, redistribution mistakes, and failures to converge after network changes.

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

pyats-routing 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.

Analysis checklist:

  • Route source codes: C (connected), S (static), O (OSPF), O IA (OSPF inter-area), O E1/E2 (OSPF external), B (BGP), D (EIGRP), D EX (EIGRP external)
  • Administrative distance and metric for each route
  • Next-hop reachability — is the next-hop IP actually reachable?
  • Recursive lookups — routes pointing to next-hops resolved through other routes
  • Equal-cost multipath (ECMP) — multiple next-hops for the same prefix
  • Default route presence and source
  • Unexpected route absence — if a prefix should be there but is not
