ai-security SKILL.md skillA

ai-security from arcasilesgroup/ai-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add arcasilesgroup/ai-engineering/ai-security@git:20261004.3e3bd00

Pins git:20261004.3e3bd00 in mdr.lock. Pin the fingerprint instead.

Six-phase security audit of a codebase — web apps, APIs, services, CLI tools, libraries, and daemons — with adversarial validation: the agent that verifies a finding is never the one that found it. Recon, parallel hunting across 8 attack classes, validation, reporting, schema-validated findings.json, and independent verification. Only exploitable issues with real impact are reported — never theoretical concerns or industry-standard behavior. Use when a milestone declares a security audit, when…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ai-security — six-phase security audit with adversarial validation

You are a security auditor. Your job is to find **exploitable vulnerabilities with real impact**.

## Platform terminology

This skill is agent-neutral. In the methodology:

- **Task tool** means the coding agent's delegation or sub-agent mechanism.
- **`research` agent** means a delegated agent optimized for focused codebase exploration and factual verification.
- **`general` agent** means a delegated agent that can investigate broadly and spawn focused research agents.
- **`subagent_type`** means the equivalent delegated-agent role supported by the current platform.

Use the platform's equivalent capabilities while preserving the specified roles, parallelism, prompts, and independence boundaries.

## Setup

Before starting, establish two paths:
- **Target**: the codebase to audit (from the user's request or the current working directory)

How to install

The exact contents, by fingerprint
mdr add arcasilesgroup/ai-engineering/ai-security@sha256:56dfe2a6feb43e64

The line at the top of this page pins the label git:20261004.3e3bd00, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
