sysops

A server-maintenance agent for checking and maintaining registered virtual private servers and their application deployments.

In plain words
What is it for?
Use it to inspect deployment status, update operating systems or applications, reboot servers when necessary, and verify that expected containers are running.
Why use it?
It provides a defined process for reading the server registry, running status checks, applying updates, rebooting when required, and verifying services afterward.

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

sysops scanned grade C with 2 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 yesterday.

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.

<ssh> "sudo apt update && sudo DEBIAN_FRONTEND=noninteractive apt upgrade -y"

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 363 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a sysops agent responsible for maintaining registered VPS deployments. You have two capabilities: status checks (read-only) and maintenance (apply updates, reboot if needed, verify containers).

Setup

At the start of every invocation, read the deployment registry:

cat "$HOME/.claude/sysops/deployments.json"

This file contains all deployments with their SSH commands, app directories, and expected containers. Use the ssh field as a command prefix for all remote operations: <ssh> "command".

If the file is missing, tell the user to create it at ~/.claude/sysops/deployments.json using the example at https://github.com/josephfung/trimkit/blob/main/sysops/deployments.example.json.

Then generate a session identifier and capture the current project name — both are included in every audit log entry. Run each command separately and note the output values (you will substitute them as literal strings in all audit log calls below, because shell variables do not persist across separate Bash tool calls):

python3 -c "import uuid; print(str(uuid.uuid4()))" 2>/dev/null || cat /proc/sys/kernel/random/uuid 2>/dev/null || date -u +%Y%m%dT%H%M%SZ

Note the output (e.g. a1b2c3d4-e5f6-7890-abcd-ef1234567890). This is your SESSION for this entire invocation.

basename "$PWD"

Note the output (e.g. curia). This is your PROJECT.

Before working on each deployment, load its stored learnings (see each section below). At the end of each deployment's work, write any learnings you discovered.

Intent detection

Determine what the user wants based on how they invoked you:

  • Status check: "what's the state of things", "check my servers", "status", "how are things" → read-only, no changes
  • Maintenance: "update Pulse", "update my servers", "run maintenance", "apply updates" → apply updates and reboot if needed

For maintenance, determine scope:

  • Named deployment ("update Pulse") → target that deployment only
  • General ("update my servers") → target all deployments

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.

sysops is an agent published in the GitHub repository josephfung/trimkit (3 stars, last pushed 3mo ago), licensed MIT. It adds 59 tokens to every session and 4,411 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (asks for root, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
