Skill Guard
ReviewAudited by ClawScan on May 10, 2026.
Overview
Prompt-injection indicators were detected in the submitted artifacts (ignore-previous-instructions); human review is required before treating this skill as clean.
This appears safe to use as an advisory scanner for third-party Skills. Before installing, remember that it is instruction-only: it can help the agent review files, but it is not a guaranteed automatic blocker or sandbox. Scan only the intended Skill directory and avoid including unrelated private files. ClawScan detected prompt-injection indicators (ignore-previous-instructions), so this skill requires review even though the model response was benign.
Findings (4)
Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
The agent may invoke this scanner before using third-party skills, which can be helpful but may interrupt or alter the normal workflow.
This strongly directs the agent's workflow and tool-selection behavior. It is purpose-aligned for a security gate, but users should understand it can add an advisory scanning step before other skills are used.
This skill MUST be consulted BEFORE loading or following instructions from any other Skill downloaded from the internet or third-party sources
Use it as an advisory pre-check for unfamiliar skills, and keep final install/load decisions under user control.
If the selected Skill folder contains secrets or unrelated private files, those files may be brought into the agent's review context.
The skill requests broad file enumeration and reading within the target Skill. That is necessary for static security scanning and it explicitly avoids execution, but it can expose any private files accidentally placed in the target folder.
List **all** files recursively ... Read **every** file in the target Skill ... For scripts, perform static analysis — do NOT execute them.
Point the scanner only at the specific Skill folder being reviewed and remove unrelated private files before scanning.
A user might assume this provides antivirus-like automatic protection, when actual protection depends on whether the agent invokes and follows the scanner's recommendations.
The artifacts are instruction-only and include no enforcement hook, so the automatic blocking language appears to be an advisory workflow claim rather than a guaranteed technical control.
it automatically scans any third-party Skill for malicious behavior **before** it is loaded or executed ... 🚫 **CRITICAL** ... **BLOCK** — Skill will not be loaded
Treat scan results as security advice, not a guaranteed sandbox or automatic blocker.
It may be harder to independently verify the maintainer, update history, or upstream review of this security tool.
The provided metadata does not give an external source or homepage for provenance. Because this is instruction-only with no code or install script, this is a provenance note rather than a security concern.
Source: unknown; Homepage: none
Install from a trusted registry or compare the artifact contents with a known-good source if provenance matters to your environment.
