Security checks for vulnerabilities and agentic risk
The skill is a UI review helper, but it delegates review rules and output instructions to a mutable remote document on every run without pinning or validation.
Review this skill before installing. It is not evidence of malware, but users should be aware that each run may behave differently based on the current contents of an external GitHub document. Prefer a version that vendors or pins the guidelines and treats remote text as untrusted reference material, not agent instructions.

SKILL.md:19Unpinned Mutable Remote Dependency Is Retrieved on Every Review
The trigger phrases are very broad and map to common user requests such as reviewing UI, accessibility, UX, or best practices, increasing the chance this skill is auto-selected in situations beyond its narrow intended scope. Overbroad activation can cause unreviewed network-fetching behavior or application of remote instructions in contexts where the user did not expect it.
The skill requires fetching remote content on every run and treats the fetched content as authoritative instructions, yet gives no warning that external network access will occur. This creates a supply-chain and prompt-injection risk: if the remote document is changed maliciously or unexpectedly, the skill may follow attacker-controlled instructions during routine audits.
The manifest frames this skill as reviewing UI code for guideline compliance, but the remediation section directs the agent to run python3 skills/ui-ux-pro-max/scripts/search.py ... commands. Spawning a Python process to query another skill is not an obvious requirement of a review-only auditing skill and introduces an execution capability beyond the stated purpose.
