Repeatability
High
Middleware refactoring follows well-established patterns — extract, unify, compose, test. The structural problem is the same regardless of the specific token logic, making this highly repeatable for a code agent.
Ambiguity Tolerance
High
Success criteria are concrete: unified error responses, composable middleware, passing unit tests for all three strategies across success and failure cases. A non-human can verify these mechanically.
Data & Tool Availability
Medium
The agent needs full read access to the existing codebase, including the three middleware files and the 40+ route definitions. If given repo access and a test runner, it has everything it needs — but access must be explicitly granted.
Error Cost
Medium
A broken auth layer could lock users out or expose protected routes, which is serious in production. However, this work should happen on a branch with tests gating any merge, making the risk reversible and containable.
Human Judgment Required
Low
The refactoring decisions here — how to compose strategies, what error shape to standardize on — are engineering conventions, not taste calls. A human review of the PR is good practice but not strictly required for the generation step.
