Repeatability
High
Framework migration tasks follow well-established patterns: Flask middleware maps predictably to FastAPI dependencies, and async/await conversion is largely mechanical. The structure is consistent enough that an agent can apply the same transformation logic reliably.
Ambiguity Tolerance
Medium
The core requirements are explicit (API key + JWT, async, FastAPI deps, docstrings), but details like JWT library choice, error response format, token expiry handling, and Redis key schema are underspecified and will require reasonable defaults or assumptions the human may need to override.
Data & Tool Availability
Medium
The agent needs the existing Flask middleware source code, Redis key schema, and any JWT secret/config conventions — none of which are provided in the task description. If the agent is given file access, this is solvable; without it, the output will be generic rather than a true port.
Error Cost
Medium
Authentication code errors can introduce security vulnerabilities (e.g., improper JWT validation, token bypass), but the output is code for review, not deployed directly. A human security review before merge keeps the blast radius manageable.
Human Judgment Required
Low
The transformation is largely technical and well-documented in both Flask and FastAPI ecosystems. Taste decisions like docstring style and dependency structure are minor and easily adjusted. No ethical or relational judgment is needed.
