Overview

This skill is a straightforward testing-guidance skill with no hidden install behavior, credential access, networking, or persistence mechanisms.

Reasonable to install for stronger test-writing discipline. Be aware that it encourages red-green proof, so an agent may propose running focused tests or briefly changing local code to confirm a test fails for the old behavior; review the final diff to ensure only intended test and implementation changes remain.

Vulnerability Patterns

• Rogue Agent: Self-Modification, Session Persistence
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium

• Confidence: 95% confidence
• Finding: The manifest description says to use the skill when Codex is adding, editing, selecting, reviewing, or explaining tests in any repository, and the body says to use it whenever test quality matters. Those triggers are extremely broad and overlap with common development activity, without clear boundaries or negative examples for when the skill should not activate.

Session Persistence

Medium

• Category: Rogue Agent

Content

description: Use when Codex is adding, editing, selecting, reviewing, or explaining tests in any repository, including mocks, fixtures, snapshots, CI validation, regression coverage, TDD/red-green proof, or readiness claims. Enforces behavior-first test design so tests catch real regressions instead of merely passing the current implementation.

# Write Better Tests

Use this skill whenever test quality matters. The goal is not "more tests"; the goal is tests a skeptical maintainer would trust.
