I Built the Tool Maintainers Actually Need

Last issue, I wrote about how open source bounties are dying. Maintainers drowning in AI-generated spam PRs. Quality contributions buried under noise. Everyone closing everything because reviewing 20 garbage submissions per bounty isn't sustainable.

I said "when a market is flooded, stop competing in it. Build your own."

So I built the thing I wished existed when my PRs were getting auto-closed.

What PR Triage Does

PR Triage is a web tool that evaluates pull requests. Not with vibes. Not by checking if the submitter has a profile picture. It reads the actual diff, fetches the linked issue, checks repo patterns, and produces a structured triage decision.

You paste a GitHub PR URL. Thirty seconds later, you get:

Everything is anchored to the diff. The system cites specific files, line changes, and pattern comparisons. No vague "the code looks reasonable" assessments.

Why This Matters

The anti-spam tools that exist right now — Anti-Slop, Vouch, PR Slop Stopper — check contributor signals. Account age. Commit history. Profile completeness. That's fine for catching the most obvious bots, but it can't answer the question that actually matters:

Does this PR solve the problem it claims to solve?

My $500 bounty PR had 18 changed files and passed 1,259 tests. It got auto-closed by a bot that thought my username looked suspicious. A tool that had actually read the diff would have scored it high on every dimension.

That's the gap PR Triage fills. It doesn't care about your GitHub profile. It cares about whether your code addresses the linked issue, follows repo conventions, has appropriate scope, includes tests, and raises any red flags.

How the Scoring Works

Six dimensions, each weighted by importance:

Issue Resolution Fit (30%) — Does the diff actually implement what the issue requested? This is the most important signal. A PR that perfectly solves the stated problem gets a high score here even if the author's account is two days old.

Implementation Substance (25%) — Are the changes functional or cosmetic? Real logic changes versus renames, formatting tweaks, and comment edits. This is where most spam falls apart. Bots love to submit PRs that look like they did something but changed nothing meaningful.

Repository Pattern Alignment (15%) — Does the code follow the repo's existing conventions? Naming, file organization, error handling patterns. Pasted-in code from a different project sticks out here.

Scope / Complexity Match (15%) — Is the change proportional to the problem? A 500-line PR for a one-line fix is suspicious. A one-line PR for a complex feature request is equally suspicious.

Test Signal (10%) — Were relevant tests added or modified? Do they actually verify what the PR claims to fix? A PR that changes core logic without touching the test directory raises questions.

Risk Flags (5%) — Red flags like unrelated file changes, suspicious patterns, or breaking changes. This dimension catches PRs that sneak unrelated modifications into otherwise legitimate-looking changes.

Each dimension is scored as Strong, Moderate, Weak, or Insufficient Data. The system excludes any dimension where it doesn't have enough information rather than guessing — and tells you exactly what context was missing.

The action recommendation isn't just "score above 80 means good." It uses a seven-layer signal hierarchy. High-severity risk flags can override a high score. Strong fundamentals across all dimensions can upgrade a borderline score. Missing critical context routes the PR to human judgment instead of making a bad automated call.

What It's Not

PR Triage is not a code review tool. It doesn't check for bugs, suggest improvements, or critique architecture decisions. That's your job as a maintainer.

It's not an AI detection tool. It doesn't try to guess whether a human or an AI wrote the code. Frankly, that distinction is becoming meaningless. What matters is whether the code is good.

It's a triage assistant. It helps you decide which of the 20 PRs in your queue are worth spending 30 minutes reviewing. That's it. Make the queue manageable, then you do the real review.

The system explicitly uses probabilistic language — "appears to," "likely," "shows signals of." It never makes definitive claims about code quality. Maintainers make the final call.

BYOK and Free

PR Triage uses your own LLM API key. Anthropic, OpenAI, OpenRouter, or Gemini. Your key is encrypted with AES-256-GCM at rest, only decrypted server-side during analysis, and never sent anywhere except your chosen provider.

Cost per analysis: roughly $0.002 for a Quick Scan. That's 500 PR evaluations for a dollar.

The free tier gives you 3 analyses per day. Enough to try it on real PRs and see if it matches your own judgment.

The whole thing is open source under MIT. You can self-host it if you want full control.

Sign in with GitHub, add your API key in Settings, paste a PR URL. First result in under a minute.

If you maintain an open source project with a PR spam problem — or if you just want to see how your own PRs score — give it a shot. I'm genuinely curious whether the scoring matches real maintainer instincts.

What's Next

This is version one. The scoring engine is calibrated but not perfect. There are edge cases I know about and probably more I don't. I'm planning:

But first I want real feedback from real maintainers. The tool is live. Use it. Tell me where the scores feel wrong.

I built this because I was on the receiving end of the spam problem. Now I want to see if it actually helps the people on the other side of the PR queue.
