Security checks for vulnerabilities and agentic risk

Overview

This positioning skill includes broader account controls and inconsistent approval rules that could cause unexpected credit spending or recurring charges.

Review the spending and monitoring controls before installing. Prefer a version that enforces positioning-only commands and prior approval. If using this package, disable automatic spending in ARI, use manual collection, and approve recurring plans separately. The disclosed API key is saved locally at ~/.ari/config.json.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

MCP Tool Poisoning
Confidence
98% confidence
Finding

The positioning-only skill includes conflicting instructions for general operations, account-wide settings, and paid generation without prior price confirmation. Although the final section restricts execution to positioning with explicit approval, the earlier actionable workflows create an authorization ambiguity that can cause out-of-scope execution and unexpected credit consumption.

Confidence

Finding

Evidence retrieval could support the declared positioning analysis, but persistent weekly monitoring, watch lifecycle management, and per-refresh price acceptance are additional operational capabilities not disclosed in the description. The supplied chunk shows watch-management commands rather than evidence-based positioning analysis. It does not establish sales forecasting or advertising execution.

Finding

Retrieving monitoring evidence could support positioning research, but managing recurring watches and accepting their pricing are additional operational capabilities not disclosed by the evidence-discussion-only description. The snippet does not show the underlying implementation or establish actual charges, but its command interface explicitly exposes those capabilities.

Finding

Retrieving Amazon evidence could support the declared positioning analysis, but configuring ongoing weekly watches and accepting recurring refresh costs are additional operational capabilities not disclosed by that description. The mismatch concerns persistent monitoring and its cost implications, not the use of ARI or Amazon resources. The supplied commands do not establish market sizing, sales forecasting, or advertising execution.

Finding

Collecting evidence can support the declared positioning analysis, but configuring ongoing, potentially billable monitoring is a distinct operational capability not disclosed in the description. The supplied commands explicitly expose that capability, although the underlying scheduler implementation is not shown.

Finding

The supplied commands expose watch-service inspection capabilities rather than the declared product-and-review evidence analysis. Watch pricing and watch inventory are not described as part of the skill's purpose, and the chunk does not establish them as supporting steps for positioning analysis. The monthly estimate appears to concern service costs, not sales forecasting. No watch creation or modification is shown.

Confidence

Finding

The comparison workflow describes binding a competitor as automatically initiating weekly collection without a local quotation-and-approval step for that continuing activity. Approval of a one-time comparison does not authorize persistent collection or potential recurring charges; general scheduling safeguards elsewhere reduce but do not remove this ambiguity.

Confidence

Finding

The supplied commands expose a watch-monitoring workflow that is not described in the declared product-positioning purpose. They do not visibly retrieve Amazon product details or reviews or perform positioning analysis. Although monitoring could potentially support such analysis, the chunk provides no connection establishing that role. The commands do not establish sales forecasting, advertising execution, creation of new watches, or unauthorized data access.

Finding

The visible command targets alerts rather than the described evidence-driven product-positioning workflow. This indicates an undeclared capability. However, the implementation of scripts/ari.py is not supplied, so the exact alert behavior, resource access, and any side effects cannot be determined.

Finding

The supplied commands expose watch-service administration and pricing rather than product-detail or review analysis. Those capabilities are not declared, and the snippet does not establish that they are supporting implementation details for evidence-based positioning. The CLI implementation is not supplied, so the assessment is limited to the visible commands and their accompanying comment.

Confidence

Finding

run_analysis changes an absent confirmation into authorization when the quote contains a truthy autoConfirm value, allowing credit-consuming requests despite the explicit --confirm guarantee. This also affects deepdive, including its purported quote-only fallback; server policy may represent prior consent, but the supplied code does not establish that and does not preserve the documented local boundary.

The automatic-confirmation rules include first-use exemptions with no amount limit, not just user-chosen spending thresholds. Treating service eligibility as financial consent can consume purchased credits before the user sees the price and conflicts with the skill's explicit-confirmation requirement.

The standard workflow deliberately skips quotation and invokes a command that may already collect data, generate a report, and deduct credits. For users without informed spending authorization, discovering the charge through the returned report is too late to prevent unwanted expenditure.
