Todoist v1 API Reference

• Outcome: Pass
• Latest audit: Sep 10, 2026 · 9:19 PM UTC
• Version: 1.0.0

Overview

This is a straightforward Todoist helper skill that uses a user-provided Todoist token to list and change Todoist items, with no hidden code or persistence found.

Install only if you intend to let the agent use your Todoist personal API token. Review mutating commands before execution, especially task deletion, and prefer completing tasks unless you are sure deletion is intended.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Findings (16)

External Script Fetching

High

• Category: Supply Chain
• Confidence: 90% confidence

Finding

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The skill documents a permanent delete operation for tasks without any warning, confirmation guidance, or recommendation to prefer safer alternatives at the point of use. This increases the chance of accidental destructive actions and data loss, especially in an agent-driven workflow where commands may be executed on a user's behalf.
