The decision context
AI coding products range from suggestions and chat to multi-step agents, but generated code is only an intermediate artifact. The decision outcome is a maintainable change that satisfies a bounded issue, passes the relevant checks, and survives human review.
Repository state, tool permissions, instructions, dependencies, tests, and model configuration all affect the result. A fair pilot freezes those conditions and keeps failed runs, unexpected file changes, and unsupported completion claims visible.
Why it matters
- A plausible diff can compile locally while breaking behavior, security, portability, or maintainability elsewhere.
- Agent permissions determine whether a mistaken plan stays a draft or changes code and external systems.
- Completion rate alone hides repair time, scope creep, flaky tests, and reviewer burden.
Questions to answer before choosing
- Which repositories, languages, issue types, and engineering controls represent the real workload?
- What files, commands, network access, secrets, and external actions may the assistant use?
- Which automated checks and human review dimensions define acceptance?
- How will prompts, interventions, run logs, failures, and final diffs be retained?
A reviewable decision path
Each step should leave a record that another reviewer can inspect.
- 01
Freeze the baseline
Record commit, environment, dependencies, issue, acceptance tests, and known failures.
- 02
Constrain authority
Use isolated branches or worktrees, scoped credentials, protected branches, and explicit tool limits.
- 03
Run matched tasks
Give each candidate the same repository snapshot, requirements, checks, and stopping conditions.
- 04
Review the whole change
Inspect behavior, tests, security, dependencies, scope, readability, and unsupported claims.
- 05
Measure the handoff
Record accepted work, repair time, reviewer effort, regressions, and rollback readiness.
