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 | $0.00340 | $0.00340 |
| Opus 5.5 | $0.00136 | $0.00136 |
| Sonnet 5.5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
agentguard CLAUDE.md scanned grade A with 0 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 25d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
GoPlus AgentGuard
Security framework for AI agents. Provides code scanning, runtime action evaluation, and trust management.
Skill
This project provides a unified Claude Code skill: /agentguard
/agentguard scan <path> — Scan code for security risks (24 detection rules)
/agentguard action <description> — Evaluate runtime action safety (allow/deny/confirm)
/agentguard patrol [run|setup|status] — Daily security patrol for OpenClaw environments
/agentguard trust <subcommand> — Manage skill trust levels (lookup/attest/revoke/list)
/agentguard report — View security event audit log
/agentguard config <level> — Set protection level (strict/balanced/permissive)
/agentguard checkup — Run agent health checkup with visual HTML report
/agentguard privacy <cmd> — Opt-in semantic privacy enhancement (status/enable/disable)
Project Structure
skills/agentguard/— Claude Code skill definition and supporting filessrc/— TypeScript source (scanner rules, registry, action detectors, MCP server)data/— Registry storage (registry.json)dist/— Compiled JavaScript output
Setup for Trust & Action CLI
The trust and action subcommands use CLI scripts that require the agentguard package:
cd skills/agentguard/scripts && npm install
For GoPlus API (optional Web3 enhancement for action evaluation):
export GOPLUS_API_KEY=your_key
export GOPLUS_API_SECRET=your_secret
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.
