AI Agent Traps ↗
Credential harvesting instructionshighcredential theftAML.T0055AML.T0037LLM02:2025

The skill explicitly instructs the agent to scan sensitive local configuration files (e.g., ~/.gemini/settings.json, .claude.json) to extract API keys, which facilitates credential theft.

Description Mismatchhighdescription mismatchAML.T0011.000LLM06:2025LLM09:2025

The skill explicitly instructs the AI to scrape sensitive API keys from local configuration files (e.g., .claude.json, .gemini/settings.json). This behavior poses a significant security risk by encouraging the exfiltration of credentials from the user's environment.

85% confidence
Section 2: 'Get the API Key' instructs the AI to locate and extract API keys from specific sensitive configuration files on the local machine.
Invalid skill name formatlowpolicy violation

Skill name does not conform to the Agent Skills spec: 1–64 lowercase alphanumeric characters and hyphens, with no leading, trailing, or consecutive hyphens.

100% confidence
stitch::upload-to-stitch
Missing licenseinfopolicy violation

Skill does not specify a license field. Specifying a license helps users understand usage terms.

100% confidence
Skill name does not match directoryinfopolicy violation

The SKILL.md 'name' field does not match the skill's parent directory name, which the Agent Skills spec requires. A mismatch can confuse skill resolution or mask the skill's real identity.

100% confidence
stitch::upload-to-stitch ≠ upload-to-stitch
