deep-security-scan skillA

deep-security-scan is agent-read markdown (skill) from cowork-os/cowork-os: Use when the user asks for a deep, exhaustive, multi-pass, or variance-reducing repository-wide Codex Security scan. Run repeated independent repository-wide discovery passes with worker-specific threat models, semantically merge candidates, synthesize one canonical validation threat model, then run validation, attack-path analysis, and final reporting once. Repository-wide targets only; do not use for PRs, commits, branch diffs, working-tree diffs, or scoped paths..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Deep Security Scan

## Overview

Deep Security Scan is a higher-recall repository-wide wrapper around Codex Security. It preserves the ordinary Codex Security phase model and final report shape, but repeats the most variance-sensitive phase, finding discovery, before centralized judgment.

The wrapper owns orchestration only:

1. resolve the full-repository scan target once using Codex Security repository-wide semantics
2. run repeated independent discovery workers, each of which generates its own repository-level threat model before `$codex-security:finding-discovery`
3. semantically merge discovery outputs into one canonical candidate inventory
4. synthesize one canonical validation threat model from the worker threat models after discovery reaches a terminal state
5. run `$codex-security:validation`, `$codex-security:attack-path-analysis`, and final report assembly once

Do not replace Codex Security's established scan rules with custom shortcuts.

## Required Capabilities

Before starting, confirm that the Codex Security plugin skills needed by this workflow are available:

- `$codex-security:security-scan`
- `$codex-security:threat-model`
