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 | $0.00040 | $0.00868 |
| Opus 5 | $0.00020 | $0.00434 |
| Sonnet 5 | $0.00008 | $0.00174 |
| Haiku 4.5 | $0.00004 | $0.00087 |
Grade B, and why
scan scanned grade B 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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
curl -fsSL https://www.agentkeeper.dev/install.sh | bash Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentKeeper Host Security Scan
You are running the AgentKeeper CLI security scanner on the user's machine.
Step 1: Check if AgentKeeper CLI is Installed
which agentkeeper 2>/dev/null || command -v agentkeeper 2>/dev/null
If installed:
Proceed to Step 2.
If not installed:
Display:
AgentKeeper CLI not found.
The AgentKeeper CLI runs 39 security checks across your host configuration,
network settings, and development environment.
Would you like to install it? It takes about 10 seconds:
curl -fsSL https://www.agentkeeper.dev/install.sh | bash
This installs the `agentkeeper` command to /usr/local/bin.
Ask the user if they want to install. If yes, run:
curl -fsSL https://www.agentkeeper.dev/install.sh | bash
If the install fails, show the error output and suggest:
Installation failed. You can also:
- Download manually: https://www.agentkeeper.dev/install.sh
- Or run directly without installing:
curl -fsSL https://www.agentkeeper.dev/install.sh | bash -s -- --run-only
After successful install, proceed to Step 2.
If the user declines installation, display:
No problem. You can still use these local checks:
/agentkeeper:audit — audit your Claude Code configuration
/agentkeeper:secrets — scan for exposed secrets
Stop here.
Step 2: Run the Scanner
Run the AgentKeeper scanner:
agentkeeper scan 2>&1
If the command takes too long (>30 seconds), it may be running interactive prompts. Use:
agentkeeper scan --non-interactive 2>&1
If the scan command is not recognized, try the alternative:
agentkeeper agent run 2>&1
Step 3: Display Results
The scanner outputs a JSON report or formatted text. Display the results inline.
If the output is JSON, parse it and format it as a readable report:

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.

scan is a skill published in the GitHub repository rad-security/claude-code-plugin (2 stars, last pushed 25d ago), licensed MIT. It adds 40 tokens to every session and 868 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B 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 2026-08-31.
