agent-owasp-compliance

agent-owasp-compliance is a skill for Claude Code, Codex from OKHP3/skillz. It costs 122 tokens per session (2,741 once invoked), scanned A, a copy of agent-owasp-compliance, MIT.

A security-review skill for checking AI-agent code against the OWASP Agentic Security Initiative 2026 Top 10 risks.

In plain words
What is it for?
Use it to assess controls such as prompt-injection protection, tool permissions, agency limits, identity, audit logging, supply-chain checks, and behavior monitoring.
Why use it?
It identifies gaps in protections for agents that access tools, systems, and data or act on a user's behalf.

Token cost

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.

Security

Grade A, and why

agent-owasp-compliance scanned grade A with 1 finding 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 6d 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.

Agent OWASP ASI Compliance Check

Evaluate AI agent systems against the OWASP Agentic Security Initiative (ASI) Top 10 — the industry standard for agent security posture.

Overview

The OWASP ASI Top 10 defines the critical security risks specific to autonomous AI agents — not LLMs, not chatbots, but agents that call tools, access systems, and act on behalf of users. This skill checks whether your agent implementation addresses each risk.

Codebase → Scan for each ASI control:
  ASI-01: Prompt Injection Protection
  ASI-02: Tool Use Governance
  ASI-03: Agency Boundaries
  ASI-04: Escalation Controls
  ASI-05: Trust Boundary Enforcement
  ASI-06: Logging & Audit
  ASI-07: Identity Management
  ASI-08: Policy Integrity
  ASI-09: Supply Chain Verification
  ASI-10: Behavioral Monitoring
→ Generate Compliance Report (X/10 covered)

The 10 Risks

Risk Name What to Look For
ASI-01 Prompt Injection Input validation before tool calls, not just LLM output filtering
ASI-02 Insecure Tool Use Tool allowlists, argument validation, no raw shell execution
ASI-03 Excessive Agency Capability boundaries, scope limits, principle of least privilege
ASI-04 Unauthorized Escalation Privilege checks before sensitive operations, no self-promotion
ASI-05 Trust Boundary Violation Trust verification between agents, signed credentials, no blind trust
ASI-06 Insufficient Logging Structured audit trail for all tool calls, tamper-evident logs
ASI-07 Insecure Identity Cryptographic agent identity, not just string names
ASI-08 Policy Bypass Deterministic policy enforcement, no LLM-based permission checks
ASI-09 Supply Chain Integrity Signed plugins/tools, integrity verification, dependency auditing
ASI-10 Behavioral Anomaly Drift detection, circuit breakers, kill switch capability

Check ASI-01: Prompt Injection Protection

Look for input validation that runs before tool execution, not after LLM generation.

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.
