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.

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 | $0.00115 | $0.03114 |
| Opus 5.5 | $0.00046 | $0.01246 |
| Sonnet 5.5 | $0.00023 | $0.00623 |
| Haiku 4.5 | $0.00012 | $0.00311 |
Grade A, and why
host-ssh 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 1mo 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 — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Host SSH (Windows PowerShell + macOS/Linux POSIX shell)
Sandbox paths — authoritative, do not discover
Your system context includes a file list ([@files] / context options). That list,
plus the rules below, fully defines what exists and where. Do not run pwd, find,
ls /, cd /home, or any other command to discover paths. Exploration wastes turns
and breaks working-directory assumptions.
SANDBOX CWD is already the notebook output directory (private notebooks: the
Output/ folder). Every run_bash / run_python call starts there.
| Rule | Do | Never |
|---|---|---|
| Skill scripts | python3 Skills/host-ssh/scripts/host_ssh.py … |
Output/Skills/…, /app/…, /home/… |
| Deliverables | bare filenames in CWD | prefix Output/ in commands |
| Change directory | stay in CWD | cd /home, cd Output, cd before skill commands |
| Inputs in the file list | use the exact path shown (../repo/…, Skills/…, bare names) |
guess, probe, or re-derive |
| Host repo edits | edit via mounted paths in the file list (bash heredoc) | run_python one-liners that embed \ or \\ |
If Skills/host-ssh/scripts/host_ssh.py appears in the file list, run it as written
from CWD. If a path is in the list, the file exists — trust the list.
Host setup (OpenSSH, guide Environment variables) is in the operator README bundled with
this skill or samples/skills/host-ssh skills/README.md on the repo. Missing
GA_HOST_SSH_* env vars → stop and tell the user to set them in the guide editor;
do not scan or guess credentials.
Machines — the guide Environment is the source of truth
GA_SSH_MACHINES (JSON array in the guide Environment) declares which machines this
guide can reach. Run host_ssh.py machines to list them — never guess a host or IP.
When no --machine is given, the record with "default": true is the target. When
GA_SSH_MACHINES is absent, the legacy single machine from GA_HOST_SSH_HOST is the
default (named host).
What ships with it
3 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.

host-ssh is a skill published in the GitHub repository Elumenotion/GuideAnts (65 stars, last pushed today), licensed Apache-2.0. It adds 115 tokens to every session and 3,114 once invoked, about $0.0005 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 2026-09-03.
