Required inputs

Parameters the script accepts. Defaults shown; some are vendor- or context-gated.

Parameter	Type	Default	Notes
Local ASN asn	number	65001	—
Blackhole community blackhole_community	string	65001:666	—
Use large communities use_large_community	bool	true	—

Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (Cisco IOS-XR, Juniper, Arista, …) so the generated routing logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for Local ASN, Blackhole community, Use large communities instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can origin tag communities and traffic-engineering communities. Ask for the subset relevant to your incident to keep output focused.

Hint 4 — Describe your inventory format

Tell the assistant whether your device list is CSV, YAML, or JSON and which columns it has, so parsing matches your data.

Sample inventory schema
