Repeatability
Medium
The pattern of converting raw SQL to Doctrine is structurally repeatable, but each of the 12 queries may embed unique business logic, joins, or edge cases that require individual judgment. It's not a pure mechanical transformation.
Ambiguity Tolerance
Medium
Success criteria are partially clear — queries must be functionally equivalent, injection-safe, and use Doctrine — but 'good' ORM design involves architectural choices (repositories, query builders, DQL vs. native SQL) where reasonable engineers disagree.
Data & Tool Availability
Medium
The agent needs full read access to the PHP codebase, schema definitions, and ideally a running environment to validate output. If those are provided, the agent can proceed; without them, it's guessing at context.
Error Cost
High
Incorrect query refactoring can silently break application behavior, introduce data integrity bugs, or leave injection vulnerabilities in place — all of which may not surface until production. Reversibility depends on version control discipline.
Human Judgment Required
Medium
Architectural decisions about how the team should write queries going forward require understanding team skill level, project trajectory, and organizational preferences — context an AI can approximate but not own. A senior developer must validate the output.
