Security checks for vulnerabilities and agentic risk
Overview
The skill is a coherent local Granola archive search helper, with sensitive data access clearly tied to its purpose and guarded by read-only-first and consent rules.
Install only if you expect the agent to inspect your local Granola meeting archive. Treat results as potentially sensitive, and review any sync or Keychain prompt before approving it. The install uses a latest Go module, so pinning or reviewing the upstream binary would reduce supply-chain ambiguity.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
