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 | $0.00088 | $0.00401 |
| Opus 5.5 | $0.00035 | $0.00160 |
| Sonnet 5.5 | $0.00018 | $0.00080 |
| Haiku 4.5 | $0.00009 | $0.00040 |
Grade D, and why
linux-server-ssh scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
box ssh "$box_id" -- "sudo apt-get install -y nginx && sudo systemctl enable --now nginx" Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
`curl -fsSL https://box.ascii.dev/install | sh`, then `box login "$BOX_API_KEY" --json`. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
`curl -fsSL https://box.ascii.dev/install | sh`, then `box login "$BOX_API_KEY" --json`. What it actually says
Linux server over SSH (Box)
Use this when the task needs an actual Linux server the user can ssh/scp into: hosting a service, running a daemon, or a remote workstation.
Why Box
- First-class SSH —
box ssh <id>opens a session; the CLI handles keys. SCP works too. - Dedicated IPv4 + full TCP/UDP — a real addressable host, not a loopback-only sandbox.
- Root Ubuntu —
apt installanything; Docker preinstalled. - Cheap & persistent — per-second billing, resumes from snapshot, ~10× cheaper than E2B/Modal at steady state.
Prereqs
curl -fsSL https://box.ascii.dev/install | sh, then box login "$BOX_API_KEY" --json.
Recipe
box_id="$(box new --json | jq -r 'select(.event == "ready") | .id')"
box ssh "$box_id" # interactive shell
box ssh "$box_id" -- "sudo apt-get install -y nginx && sudo systemctl enable --now nginx"
box info "$box_id" --json # shows the IP
Honest limits
EU-only region; 100 active VMs soft cap; disk-level snapshots (running processes don't survive stop/resume). For 1000+ concurrent servers or <500 ms boot, use Daytona/E2B/Modal.
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.

linux-server-ssh is a skill published in the GitHub repository ariana-dot-dev/cloud-sandbox-vm-skills (3 stars, last pushed 1mo ago), licensed MIT. It adds 88 tokens to every session and 401 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
