How Do I Evaluate an AI Coding Tool?

Evaluate an AI coding tool on real repository outcomes, not a scripted demo. Use the same representative tasks for every candidate and measure correctness, review effort, speed, cost, security, and maintainability.

Create a small test set: one bug with a reproduction, one multi-file feature, one refactor, one test-writing task, and one code-review task. Provide identical acceptance criteria and repository state. Record whether the tool understood the codebase, proposed a sensible plan, stayed in scope, ran the right checks, and explained its changes.

Score the workflow as well as the model. Check permissions, working-directory isolation through git worktrees or separate clones, rollback, project rules, background visibility, model selection, BYOK, usage controls, data handling, and team administration. Count active human minutes, failed attempts, merge conflicts, and defects found after acceptance.

Verdent's current documentation describes Plan Mode, parallel workers, isolated workspaces, Reviewer, and multi-model options. Compare those features with a simpler single-agent baseline. A tool is valuable when it lowers total delivery cost while preserving developer understanding. Run the pilot long enough to include failure recovery; successful happy-path generation reveals only part of the product.
