AI Tool Effectiveness Intelligence
Your AI tools tripled your PRs. Did they triple your shipping speed?
Sound familiar?
AI tools are boosting productivity
Everyone's shipping faster. The AI is catching bugs. The investment is paying off. The dashboard says 40% of code is AI-generated.
Nobody's measured what changed
Code volume went up. Review time went down. But are the reviews meaningful? Are the suggestions landing? You don't have the data to know.
The Review Tax
AI tools accelerated code generation. But review didn't scale. The result: your fastest developers wait for reviews. Your best engineers spend hours processing bot noise. Individual speed went up. Organizational velocity didn't.
That gap has a name now.
"Individual speed is not organizational velocity."
We measured it. Reviewer effectiveness.
Reviewer effectiveness: the percentage of review comments that lead to actual code changes.
Most AI bots land between 45–65%.
Now you can see exactly where the gap is.
The cost adds up.
Senior engineer time spent reviewing AI-generated noise instead of building.
Annual AI tool spend with no evidence of effectiveness.
AI bot review comments that lead to zero code changes.
The metric your current tools don't measure.
Guardian analyzes your pull request history and shows you which reviewers — human and AI — leave comments that actually lead to code changes. No code access. No guesswork. Just your Git history, measured honestly.

How it works
No workflow changes. Guardian observes. You decide.
Read-only access. No code changes required.
The CFO asks about your AI tool ROI. Do you have the answer?
PRs tripled. Shipping speed didn't change. Where's the bottleneck?
You already know the bot is noisy. Now prove it.
How Guardian measures
Guardian reads your PR history and builds a causal model of your code review process. No agents in your CI pipeline. No code changes required.

A 40-person engineering team connected Guardian and discovered their AI review bot had a 34% effectiveness rate — less than half the human baseline. Within 30 days, they reconfigured their bot rules and recovered an estimated 12 hours per week of developer attention.
