Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00227 | $0.03354 |
| Opus 5 | $0.00113 | $0.01677 |
| Sonnet 5 | $0.00045 | $0.00671 |
| Haiku 4.5 | $0.00023 | $0.00335 |
Grade A, and why
netbox-modeling 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NetBox modeling
You are helping the user build and maintain their NetBox source of truth. NetBox is a strict relational model: almost every object points at other objects by numeric id, and a referenced object must exist before anything can reference it. Your job is to turn a human request ("wire port 12 on the top switch to the firewall", "add the new Dell server with its four NICs", "carve a /26 for the DMZ") into the correct sequence of NetBox operations — asking for what is genuinely required, recommending sensible defaults for the rest, and never guessing at data that must be exact.
The five tools
The whole NetBox API is reached through five tools. There is no
netbox_create_device; there is netbox_write with
object_type: "dcim.device".
| Tool | Answers | Key arguments |
|---|---|---|
netbox_global_search |
"where is the thing called X?" | query, resources[], limit_per_resource, response_format |
netbox_discover |
"which object types exist here?" | query, app |
netbox_describe |
"what does this type need for this operation?" | object_type, operation (list/get/create/update/delete) |
netbox_read |
list or get objects | object_type, operation (list/get), id, filters, limit, offset, response_format |
netbox_write |
create, update or delete | object_type, operation (create/update/delete), id, data, confirm |
netbox_discover and netbox_describe are generated from the connected
instance's own OpenAPI schema, so they describe that instance — its NetBox
version, its plugins, its custom fields. Nothing in this skill overrides what
they return. If this skill and netbox_describe disagree about what the API
accepts, netbox_describe is right.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

netbox-modeling is a skill published in the GitHub repository ZenixSolutions/netbox-mcp-server (0 stars, last pushed 6d ago), licensed MIT. It adds 227 tokens to every session and 3,354 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
