Required inputs

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

Parameter	Type	Default	Notes
Pool Util Warning % util_warn_pct	number	75	—
Pool Util Critical % util_crit_pct	number	90	—

Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (cisco-ios, cisco-nxos, arista) so the generated fault logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for Pool Util Warning %, Pool Util Critical % instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can dHCP and scope. 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

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.
