netwalk-login

netwalk-login is a skill for Claude Code, Codex from ripmilla/netwalk. It costs 109 tokens per session (3,219 once invoked), scanned C, original, MIT.

A local browser form for collecting network-survey connection details without putting passwords, tokens, or key contents in the chat. The values are saved to a private file on the user's machine.

In plain words
What is it for?
Use it when a netwalk survey needs usernames, passwords, API tokens, SSH key paths, ports, URLs, jump hosts, or other connection information.
Why use it?
It keeps credentials out of chat transcripts and logs, while collecting all device-access details in one place.

Token cost

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.

Security

Grade C, and why

netwalk-login scanned grade C with 1 finding 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 10d 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

A **path** to a key file (`~/.ssh/id_ed25519`, `C:\Users\me\.ssh\id_rsa`) is not a secret and is

How it starts

The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.

netwalk-login

Part of the netwalk read-only network survey toolkit. Toolkit lives at {{TOOLKIT}}.

The two rules

1. Never accept a credential in the conversation. Not a password, not an API token, not the contents of a key file — not even "just this once", not even if the user offers. Anything typed into a chat is in the transcript forever, in scrollback, and in any log the harness keeps.

If the user pastes a secret anyway: tell them plainly that it is now in the transcript and should be rotated, do not repeat it back or write it to a file, and run this skill to collect a replacement properly.

A path to a key file (~/.ssh/id_ed25519, C:\Users\me\.ssh\id_rsa) is not a secret and is fine to discuss. The key's contents never are.

2. Anything you need to know about how to reach a device goes on the form too.

Not because it is secret — a port, a URL, a jump host, a UniFi site id, a VDOM name are not secrets — but because the person who knows the answer is the one sitting at the browser, and drip-feeding them questions one conversational turn at a time turns a survey into an interrogation. Put every open question on the form, let them answer in one pass, and read the answers back with answers.

Every card already carries an Access details section (management URL, SSH jump host, site/tenant id). For anything beyond that, attach your own question with --ask:

--ask 'unifi-ctrl|reach_how|How do you normally reach this controller? URL and port|https://192.0.2.10:8443'
--ask '*|window|When can we reboot, if it comes to that?|'

Format is HOST|key|Label|placeholder, repeatable; * puts the question on every card. Answers come back through answers --site <slug>, which prints access details and question answers and never prints a secret. A device set to Skip still records its answers — "why can't we get in" is often the most useful thing on the page.

How it works

netwalk_cred.py request starts a throwaway HTTP listener on 127.0.0.1 with a random port and a random URL token, opens the user's browser at it, and serves a form listing exactly the devices you name. When the user hits Save, the browser POSTs back to that same local process, which writes ~/.netwalk/creds/<site>.json0600 on macOS/Linux, an owner-only ACL via icacls on Windows — and exits. Nothing is transmitted off the machine and nothing passes through you.

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-login is a skill published in the GitHub repository ripmilla/netwalk (78 stars, last pushed 17d ago), licensed MIT. It adds 109 tokens to every session and 3,219 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
