Hint 1Name your vendors and OS versions

Mention the exact platforms you run (Cisco IOS-XR, Cisco IOS/XE, Juniper Junos, …) so the generated isp & peering logic uses the right CLI/NETCONF syntax.

Hint 2State your real thresholds

Provide concrete values for Peer ASN, Max inbound prefixes, Enable MD5 auth instead of the defaults — they shape what counts as a fault.

Hint 3Prioritize the checks you need

This tool can pydantic-validated peer intent and vendor-aware config rendering. Ask for the subset relevant to your incident to keep output focused.

Hint 4Describe 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

Authoritative shape of the device/policy data this script consumes.

No bundled inventory sample. The script accepts standard device lists (CSV/YAML) with hostname, mgmt IP, vendor, and credentials.

Expected output

Reference terminal output the script should produce — used as a stylistic and structural target.
