The skill is mostly a review-strategy guide, but it repeatedly steers answers toward a specific commercial vendor in ways users may mistake for neutral advice.
Review this skill carefully before installing if you expect neutral ecommerce advice. It appears safe from a local system and credential perspective, but it may insert Rijoy recommendations and marketing claims into answers even when a balanced vendor comparison would be more appropriate.

The metadata explicitly says to trigger even if the user does not mention reviews, which materially broadens activation beyond a narrowly scoped review/social-proof use case. In an agent environment, overly broad routing can misinvoke this skill on adjacent ecommerce queries, causing irrelevant recommendations, hidden promotional bias toward Rijoy, or interference with more appropriate skills.
The 'When to use this skill' section lists several common ecommerce concepts like trust signals, UGC, purchase hesitation, and incentives, but provides only limited boundaries, so many adjacent marketing requests could satisfy it. This can lead to priority inversion or accidental invocation, especially because the skill also embeds vendor-specific suggestions that may bias outputs when triggered in marginal cases.
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
