Rental Advisor

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent rental advisor, but it asks the agent to run broad live searches and even use shell-based curl scraping without clear limits.

Review this skill before installing if your agent has shell, web, profile-memory, or alerting tools enabled. It appears aimed at legitimate rental help, but you should restrict it to user-requested searches, prefer bounded web/search tools over exec + curl, and avoid storing rent/profile data or creating alerts unless the user explicitly agrees.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The top-level description is broad enough to activate on many ordinary housing conversations, causing the skill to engage outside a narrowly intended scope. Overbroad triggering increases the chance of unintended tool use, unnecessary data collection, or the model following this skill when a simpler non-tool response would suffice.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The Area Recommendation trigger criteria are scenario-based and open-ended, so the skill may activate for vague location discussions that do not require this workflow. In context, this matters because the skill then instructs requirement collection and potential follow-on searches, expanding data handling and action-taking from a loosely matched prompt.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The Property Search triggers are especially broad for a function that can perform external searches and collect listing/contact details. Because this function can reach external sources and handle current market data, ambiguous activation creates a higher risk of unnecessary scraping, privacy issues, or unsafe tool use compared with purely advisory behavior.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

Phrases such as 'Asks what to watch out for when signing' and 'Worried about contract traps' are broad, everyday expressions that could match many generic legal or consumer questions. The section does not provide enough specificity or exclusions to prevent accidental activation.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill explicitly authorizes exec + curl for web scraping, which expands the capability from bounded information retrieval to general shell execution. In an agent setting, this can enable command execution, unsafe network access, or abuse of user-influenced inputs if later combined with dynamic parameters, making the skill materially riskier than a normal rental-advice workflow requires.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

Statements like 'Whether rent in a certain area/community is reasonable' and 'Reasonable rent range for certain conditions' are intent descriptions, not precise triggers. Without examples of non-triggering cases or stricter scope, the activation boundary remains ambiguous.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

The document presents dispute-resolution channels and legal resources entirely in one locale/jurisdictional framing, including a specific government hotline, without indicating that these resources may vary by user region. This can amount to a language/locale policy issue because it implicitly assumes a specific locale rather than offering a choice or clarifying the intended jurisdiction.
