Time Capsule

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-style skill for leaving future-facing codebase notes, with no executable payload, network use, credential handling, or hidden install behavior found.

Before installing, expect this skill to encourage durable notes in a repository. Use it deliberately for project knowledge, avoid storing secrets or private personal data in capsules, and review any generated trigger mechanism before committing it.

A.I.G

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

Vague Triggers

Medium

Confidence: 95% confidence
Finding: The 'When to Invoke' section lists broad situations such as 'After making a non-obvious decision' and 'When writing code you know will be confusing' without defining concrete trigger phrases, boundaries, or exclusion conditions. In a markdown skill description, this can make activation overly subjective and increase the chance of unintended invocation during normal development conversations.
