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 | $0.00000 | $0.04478 |
| Opus 5.5 | $0.00000 | $0.01791 |
| Sonnet 5.5 | $0.00000 | $0.00896 |
| Haiku 4.5 | $0.00000 | $0.00448 |
Grade C, and why
sysadmin 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 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.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
- **GHCR images stay PRIVATE.** Never tell the user to flip the package to public to simplify pulls (image layers leak source and, frequently, baked-in secrets). The CI push uses the automatic `GITHUB_TOKEN` (`packages: Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- **SSH hardening goes in a drop-in that sorts before cloud-init's.** Debian cloud images ship `/etc/ssh/sshd_config.d/50-cloud-init.conf` with `PasswordAuthentication yes`. sshd uses the FIRST value found and reads `ssh The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
11 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.

sysadmin is a skill published in the GitHub repository adrienlupo/Claude-code-config (3 stars, last pushed 8d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 4,478 tokens. A static security scan graded it C with 2 findings (subtle steering, asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
