ClawSec is a collection of security skills and signed advisory data for AI agent runtimes. It helps operators verify skills, detect configuration changes, audit agent environments, and require approval for risky installations across OpenClaw, NanoClaw, Hermes, and Picoclaw. The catalogue entries are ClawSec’s skills, plugins, and instructions for those runtimes.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00035 | $0.02257 |
| Opus 5 | $0.00017 | $0.01128 |
| Sonnet 5 | $0.00007 | $0.00451 |
| Haiku 4.5 | $0.00003 | $0.00226 |
Grade B, and why
clawsec-nanoclaw scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
trap 'rm -rf "$TMP_DIR"' EXIT 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.

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.

clawsec-nanoclaw is a skill published in the GitHub repository prompt-security/clawsec (1,101 stars, last pushed today), licensed AGPL-3.0. It adds 35 tokens to every session and 2,257 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
