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 | $0.00091 | $0.01645 |
| Opus 5 | $0.00046 | $0.00822 |
| Sonnet 5 | $0.00018 | $0.00329 |
| Haiku 4.5 | $0.00009 | $0.00164 |
Grade A, and why
netwalk-map 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 6d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
netwalk-map
Part of the netwalk read-only network survey toolkit. Toolkit lives at {{TOOLKIT}}.
Run it
python3 {{TOOLKIT}}/scripts/netwalk_map.py ~/.netwalk/sites/acme-hq/scan-2026-08-22.json \
-o ~/.netwalk/sites/acme-hq/map.svg \
[--public] [--title "Acme HQ — after the switch swap"] [--top-down] [--no-group-aps]
Output is one self-contained SVG: no external fonts, no scripts, no network requests. It opens in a
browser, drops into a document, and follows the reader's light/dark setting. netwalk-fullreport
embeds the same renderer, so the diagram in the report and the standalone file never drift apart.
--public drops the scan date and the unreachable-device count from the caption.
The record is the source of truth
The renderer draws only what the record says. Never hand-edit the SVG — fix the record and re-render, or the diagram and the report start telling different stories and the next scan silently reverts your edit.
Layout is deterministic and reads left to right, the way a packet travels: internet uplinks in a column on the left, then the gateway, then each layer of switching, then the edge. Devices are ranked by BFS depth from the gateway and ordered inside each rank to minimise crossings. A rank with more devices than fit in one column wraps into another column rather than running off the page. Same record in, same SVG out — so two scans of one site diff cleanly and a changed diagram means a changed network.
--top-down stacks it vertically instead, which suits a shallow network or a portrait page.
What the record needs for a good diagram
| Field | Effect if missing |
|---|---|
devices[].vendor |
falls back to a lettered chip instead of a logo |
devices[].hostname, mgmt_ip |
the box is hard to identify |
devices[].model, os_version |
the version line is empty — and version is what people read a diagram for at upgrade time |
devices[].role |
everything lands in one flat rank and the layout stops meaning anything |
devices[].health |
no CPU/RAM/storage/temperature chips |
topology_edges[].a_port / b_port |
links have no port labels, so nobody can trace a cable from the picture |
wan_links[] |
no uplink boxes at all |
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.
- 6d ago First seen · 117 lines · 91 tokens per session scan A e54f199184c5
netwalk-map is a skill published in the GitHub repository ripmilla/netwalk (76 stars, last pushed 13d ago), licensed MIT. It adds 91 tokens to every session and 1,645 once invoked, about $0.0005 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 2026-08-30.
