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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 82 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
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 | $0.00110 | $0.02485 |
| Opus 5.5 | $0.00044 | $0.00994 |
| Sonnet 5.5 | $0.00022 | $0.00497 |
| Haiku 4.5 | $0.00011 | $0.00248 |
Grade A, and why
netwalk-diag 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 2mo 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
netwalk-diag
Part of the netwalk read-only network survey toolkit. Toolkit lives at {{TOOLKIT}}.
netwalk-scan answers what is out there. This skill answers what is wrong with it.
Read-only, and it is enforced
Config is exported, never imported or edited. Not one command changes device state — that
includes clear counters, dmesg -C, systemctl restart and debug, all of which the gate
refuses. If a device needs a change, that is a finding with a recommendation, and the site owner
decides. Run everything through netwalk_exec.py so the guarantee holds and the command lands in
the evidence log.
1. Collect
Assumes a credential exists (netwalk-login) and the vendor is known.
T={{TOOLKIT}}
python3 $T/scripts/netwalk_exec.py run --site acme-hq --host gw01 \
--cmd-file $T/scripts/packs/mikrotik.config.txt \
--out ~/.netwalk/sites/acme-hq/configs/gw01.conf \
--evidence ~/.netwalk/sites/acme-hq/evidence.jsonl
python3 $T/scripts/netwalk_exec.py run --site acme-hq --host gw01 \
--cmd-file $T/scripts/packs/mikrotik.health.txt \
--evidence ~/.netwalk/sites/acme-hq/evidence.jsonl
Packs: mikrotik, cisco, aruba, hp, fortinet, linux, windows, each with a
.config.txt, a .health.txt and a .security.txt. Record the exported config path in
config_export_path — relative to the site folder, never pasted into the report.
Run the security pack too, and run it with --out — it deliberately pulls the parts of the
configuration that hold community strings and key material, so its output must land on disk
rather than in the conversation:
python3 $T/scripts/netwalk_exec.py run --site acme-hq --host gw01 \
--cmd-file $T/scripts/packs/mikrotik.security.txt \
--out ~/.netwalk/sites/acme-hq/configs/gw01.security.txt \
--evidence ~/.netwalk/sites/acme-hq/evidence.jsonl
Always use --out for a config export. With --out the full text is written straight to a
0600 file and only a one-line summary is printed. Without it, the whole config comes back through
you — and a vendor config is packed with PSKs, SNMP communities, RADIUS secrets, password hashes and
container environment variables. Anything that reaches you is transmitted to a model API and written
into the session transcript, and neither can be un-sent.
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.

netwalk-diag is a skill published in the GitHub repository ripmilla/netwalk (86 stars, last pushed 2mo ago), licensed MIT. It adds 110 tokens to every session and 2,485 once invoked, about $0.0004 per session on Opus 5.5. 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.
