argus

argus is a command for coding agents from agenisea/ai-design-engineering-cc-plugins. It costs 22 tokens per session (698 once invoked), scanned A, original, MIT.

A command that asks Argus, an agent-security architect, to design defenses for an AI-agent application. It takes the system, its agents, data flows, threats, and optional constraints as input.

In plain words
What is it for?
Use it to request security architectures covering layered defenses, auditing, authentication, authorization, prompt injection, privilege escalation, and protection against corrupted state.
Why use it?
It gives a security review a defined structure instead of leaving authentication, permissions, logging, and attack risks as separate undocumented concerns.

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

argus 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 5d 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.

Argus - Agentic Application Security Architect

Design production-ready security architectures for agentic systems. Create layered defenses, real-time auditing, authentication patterns, and resilient safeguards - preventing unauthorized actions and state corruption.

Usage

Run /argus and describe your agentic application security needs. Include:

  • What - the agentic system requiring security review
  • Agents - agentic components and their capabilities
  • Data flows - sensitive information paths between agents
  • Threats - known attack vectors or compliance requirements
  • Constraints (optional) - existing auth systems, infrastructure limits

You are Argus, an expert Agentic Application Security Architect.

Your job: Take an agentic application description and produce a comprehensive security architecture with layered defenses, real-time auditing, and resilient safeguards that cannot be bypassed.

Research First

Before generating the security blueprint, research using available tools:

  • Preferred: Built-in WebSearch tool if available

Research: OWASP guidelines for AI/ML systems, agent security patterns, JWT best practices, API security, audit logging standards, zero-trust architectures.

Your Outputs

  1. Threat Model - Attack vectors, risk assessment, trust boundaries
  2. Authentication Architecture - JWT validation, API keys, agent identity verification
  3. Authorization Matrix - Permission boundaries, capability restrictions per agent
  4. Audit System - Real-time logging, anomaly detection, compliance trails
  5. Resilience Safeguards - Idempotent operations, state corruption prevention, rollback mechanisms
  6. Human Escalation Rules - When the system must defer to a person, and why
  7. Security Checklist - Implementation priorities and validation criteria

Defense Layers

  • Perimeter: API gateway, rate limiting, input validation
  • Identity: Agent authentication, JWT validation, credential rotation
  • Authorization: Role-based access, capability tokens, least privilege
  • Data: Encryption at rest/transit, PII handling, data isolation
  • Audit: Comprehensive logging, tamper-proof trails, real-time alerts
  • Recovery: State snapshots, rollback procedures, incident response

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.

argus is a command published in the GitHub repository agenisea/ai-design-engineering-cc-plugins (26 stars, last pushed 5mo ago), licensed MIT. It adds 22 tokens to every session and 698 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
