You've decided to try AI code review. You've read the pitch. Now the question is practical: how do you actually run a pilot that produces useful results and gives you enough information to decide whether to continue?
This is a concrete, four-week plan. Each week has a clear goal, specific actions, and defined success criteria. Follow it and you'll have either a compelling case for broader adoption or a clear understanding of why the tool isn't right for your team.
Before you start: pick the right codebase
The pilot codebase matters. Pick one that meets these criteria:
- Meaningful size. At least 50,000 lines of code. A small utility project won't produce enough findings to evaluate the tool properly.
- Active development. Choose a codebase your team is actively working in, not a dormant archive. You want findings that are relevant to current work.
- Known problems. Ideally, pick the codebase where your team already suspects there's technical debt. If the review confirms what you suspected (and finds things you didn't), that's a strong signal.
- Reasonable scope. For a first pilot, a single service or application is better than a monorepo with 20 packages. You can expand the scope later.
Assign one engineer as the pilot lead. This person runs the reviews, triages findings, and reports back to the team. It doesn't need to be a senior engineer – anyone with familiarity with the codebase can do it.
Week 1: First scan and initial findings
Goal: Run your first full-codebase review and understand the output.
Day 1-2: Install VibeRails and configure it with your existing Claude Code or Codex CLI installation. Add your pilot codebase as a project. This should take under 30 minutes.
Day 2-3: Run your first review session. VibeRails will orchestrate the AI to read every file in the project and produce findings across 17 detection categories. Depending on codebase size, this takes anywhere from 20 minutes to a few hours.
Day 3-5: Explore the findings. Don't triage yet – just read. Get a feel for what the tool is surfacing. Note how many findings are in each category. Identify a few that look clearly correct, a few that look clearly wrong, and a few you're unsure about.
Success at end of Week 1: You've completed one full review, you have a set of findings, and you have a preliminary sense of the signal-to-noise ratio. Export the HTML report – you'll use it in Week 2.
If you see too few findings: Check that the review scope includes all relevant directories. Some projects have code spread across non-obvious paths. Also consider whether the codebase is genuinely well-maintained – in which case, the tool is correctly reporting fewer issues.
Week 2: Team triage
Goal: Get the team involved and establish consensus on finding quality.
Day 1: Schedule a 60-minute triage meeting with 2-3 engineers who know the pilot codebase. Share the exported HTML report in advance so people can skim the findings before the meeting.
During the meeting: Walk through findings together. For each one, ask three questions:
- Is this real? Does the finding identify an actual problem in the code, or is it a false positive?
- Did we know about this? Was this a known issue, or is it something the team hadn't noticed?
- Is it worth fixing? Given the severity and the effort involved, should this go into the remediation backlog?
After the meeting: Triage the findings in VibeRails. Accept findings the team agrees are real and worth addressing. Reject false positives. Defer findings that are real but low priority.
Success at end of Week 2: You have a triaged set of accepted findings. You know the acceptance rate (what percentage of findings were real and actionable). You have team buy-in on the quality of the tool's output.
If the acceptance rate is low: Below 30% suggests the tool is generating too much noise for this particular codebase. Consider whether the codebase is an unusual case, or whether the team's standards for “actionable” are different from what the tool is calibrated for. Either way, that's a useful data point.
Week 3: Fix and measure
Goal: Fix the top accepted findings and measure the effort involved.
Day 1: Select the top 5 accepted findings by severity. These are the ones the team agreed are real, important, and worth addressing.
Day 2-4: Fix them. For each finding, you have two options:
- Manual fix: An engineer addresses the finding directly. Track how long this takes.
- AI-assisted fix: Use VibeRails' dispatch feature to start an AI fix session that implements changes in your local repo. Review the diff, test it, and commit or revert. Track how long this takes compared to manual.
Day 5: Document what you found. For each of the 5 fixes, record:
- What the finding was (category, severity, file)
- Whether the team already knew about it
- How long the fix took
- Whether the AI-assisted fix was usable or required significant manual rework
Success at end of Week 3: You've fixed 5 real issues that the tool identified. You have concrete data on time-to-fix and on the quality of AI-assisted remediation. You know whether the tool found things the team hadn't previously identified.
If the fixes take too long: Evaluate whether the issue is with the findings (too complex to address efficiently) or with the AI fix suggestions (low quality). The former is a prioritization issue. The latter is a product quality signal – and it doesn't invalidate the review findings themselves.
Week 4: Present results
Goal: Compile the pilot results and present to leadership.
Day 1-2: Prepare a summary. You're answering three questions:
- What did it find? Total findings, acceptance rate, breakdown by category. How many were previously unknown to the team?
- What did we fix? The 5 fixes from Week 3, including what the issues were, how long they took, and their potential impact if left unaddressed.
- Should we continue? Your recommendation, based on finding quality, team feedback, time investment, and value delivered.
Day 3: Present to engineering leadership. Use the exported HTML reports as supporting material – they're shareable and self-contained, which makes them effective in meetings where not everyone has access to the codebase.
Day 4-5: Based on the discussion, decide on next steps. If the pilot was successful, define the expansion plan: which additional codebases to review, how often to run reviews, and whether to purchase a license.
Success at end of Week 4: Leadership has seen concrete data from the pilot. There's a clear decision – expand, continue piloting, or stop – based on evidence, not speculation.
What good looks like
A successful 30-day pilot typically produces these outcomes:
- The review surfaces findings the team didn't know about – not just confirmation of known issues, but genuinely new insights.
- The acceptance rate is above 50% – more than half the findings are real and actionable.
- The team triage meeting generates productive discussion about codebase health, not just about the tool.
- At least a few of the fixes address issues that could have caused production incidents if left unaddressed.
- The total time investment for the pilot lead is under 15 hours across the four weeks.
If your pilot doesn't hit all of these, it doesn't mean the tool is wrong for your team. It might mean the pilot codebase was an unusual choice, or that the team's codebase is in better shape than expected. Both are useful things to learn.
Get started
VibeRails is free for up to 5 issues per review session – enough to run Week 1 of this pilot without any commitment. Download it, pick your codebase, and run your first review. If the findings are useful, continue with the plan.
Limits and tradeoffs
- It can miss context. Treat findings as prompts for investigation, not verdicts.
- False positives happen. Plan a quick triage pass before you schedule work.
- Privacy depends on your model setup. If you use a cloud model, relevant code is sent to that provider; local models can keep inference on your own hardware.
