gift-occasion-planner

Security checks for vulnerabilities and agentic risk

Overview

This is a local gift-planning skill with some documentation and behavior mismatches, but no evidence of hidden access, exfiltration, persistence, or unsafe execution.

Reasonable to install if you want a local gift planner. Review the generated gifts.json and ICS files before sharing or importing them into a cloud-synced calendar, because they may contain personal notes, budgets, interests, and taboo gift information. Treat one-time occasions cautiously because the current script may make them recur annually.

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

Findings (4)

Tp4

High

Category: MCP Tool Poisoning
Confidence: 93% confidence
Finding: The code largely matches the declared gift-planner purpose: it stores people and occasions, computes upcoming occasions, generates recommendations avoiding near-duplicates and taboo items, tracks budgets, logs gifts, and exports calendar reminders. However, the description is not fully accurate. The ICS feature is described as exporting reminders at 21/7/1 days out, but the code exports at 60/21/7/1 days. The declared per-person gift profile includes interests, sizes, favorites, taboo list, and past gifts; the code supports interests, sizes, taboo, notes, and uses a separate global history log rather than a per-person embedded past-gifts profile, with no favorites field. The buying plan is described as including what, budget, where, wrap, and card, but the stored plan only captures idea/where/cost/status and renders generic wrap/card guidance rather than structured fields. Also, add-occasion advertises one-time dates, but occurrence calculation ignores the stored year, so behavior is not exactly as implied. These are material description-versus-behavior differences, though the overall primary purpose remains aligned.

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.
Content: No source excerpt is available for this finding.

Intent-Code Divergence

Medium

Category: Not specified by scanner
Confidence: 98% confidence
Finding: The CLI help text says --date is for one-time occasions, implying the year matters and the event should not recur. However, the implementation strips the month and day into occ['month_day'] and next_occurrence ignores the stored year, causing the occasion to recur annually.
Content: No source excerpt is available for this finding.

Description-Behavior Mismatch

Low

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The manifest description specifically says the skill exports ICS reminders at 21, 7, and 1 days before an occasion. The implementation emits reminders at 60, 21, 7, and 1 days, so the exported behavior is broader than the stated description.
