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.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00048 | $0.00469 |
| Opus 5.5 | $0.00019 | $0.00188 |
| Sonnet 5.5 | $0.00010 | $0.00094 |
| Haiku 4.5 | $0.00005 | $0.00047 |
Grade C, and why
cli 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 9d 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.

Arcjet CLI
Preferred way to get a real ARCJET_KEY before writing Arcjet code. Do not
leave the key as a TODO.
npx -y @arcjet/cli@latest auth status
# if not signed in:
npx -y @arcjet/cli@latest auth login
npx -y @arcjet/cli@latest teams list --output json --fields id,name
npx -y @arcjet/cli@latest sites list --team-id <team_id> --output json --fields id,name
npx -y @arcjet/cli@latest sites get-key --site-id <site_id> --output json --fields key
Write key to the project's env file as ARCJET_KEY=ajkey_.... Match
existing env-file conventions and .gitignore. Never hardcode the key.
Frequent use: npm install -g @arcjet/cli, brew install arcjet/tap/arcjet,
or curl -sSfL https://arcjet.com/cli/install.sh | bash.
--output json and --fields keep agent context small. Confirm with the
user before write or delete operations (--confirm).
Investigate: requests list / guards list / requests explain /
guards explain / briefing. Remote rules: rules create (DRY_RUN) →
analyze dry-run-impact → rules promote.
If the CLI cannot run, load @arcjet/skills#mcp or send the user to
https://console.arcjet.com.
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.

cli is a skill published in the GitHub repository arcjet/arcjet-js (692 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 469 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
