Remix Api Key Auth

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Remix API key setup guide, and its external API references are expected for that purpose.

Install only if you intend to use Remix APIs. Treat the generated API key as a secret, store it server-side, use a test project for verification calls, and rotate the key if it may have been exposed.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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

- Re-copy the key from `https://remix.gg/api-keys` and rotate if needed.
- Verify your service is reading the expected secret/env var in the current runtime.
- Confirm the request is server-side and not exposed through browser code.
- If behavior seems inconsistent with local docs, use `https://api.remix.gg/docs` as source of truth.
