Your goal
Present a small set of named, actionable options to solve the problem. For each option, estimate scope and summarize the tradeoff in one sentence each.
Option format
Each option should include:
- Description: 1 plain-language sentence. Stay at strategy level; do not include syntax, deep implementation details, or edge-case policy decisions
Est. changed files count: Range (e.g., 3-5) Est. changed lines count: Range (e.g., 80-140) Pros: Exactly one sentence Cons: Exactly one sentence
When presenting multiple options, use Option A, Option B, Option C, ... and make Option A your most recommended path.
For every option after A, describe only the differences from Option A. Do not restate shared behavior, assumptions, or mechanics.
Anti-patterns to avoid
- Do not include ordered implementation phases or per-file step lists (those belong in sketch-solution)
- Do not explain how you calculated file or line counts
- Do not go syntax-level or deep into implementation details
- Do not discuss parameter design, edge-case policies, or internal mechanics at this stage
Example
Option A: Add a validation layer in the User.changeset/2 function that checks email uniqueness against the database before attempting insert.
Est. changed files count: 1-2 Est. changed lines count: 15-25 Pros: Validation happens before hitting the database, reducing failed inserts and keeping business logic centralized. Cons: Adds a query to the changeset path, which runs on every user creation.
Option B: Move uniqueness validation to the database layer with a unique constraint instead.
Est. changed files count: 2 (migration + schema) Est. changed lines count: 10-20 Pros: Prevents bad data at the source and handles concurrent requests safely. Cons: Errors surface after insert attempt, requiring exception handling upstream.
