PR triage gate for overwhelmed OSS maintainers

A CI gate that scores and filters low-effort/AI-dumped PRs before they consume open-source maintainer review time.

I want to build a small, bootstrappable product. Help me plan and start the MVP.

Product: PR triage gate for overwhelmed OSS maintainers
What it is: A CI gate that scores and filters low-effort/AI-dumped PRs before they consume open-source maintainer review time.
Who pays: Maintainers and engineering leads at funded open-source projects and foundations (e.g., projects like Plotly, QGIS-scale, or corporate OSS offices) with an infrastructure/community budget, paying $200–800/mo for CI add-ons.
Closest alternatives: CodeRabbit, GitHub Copilot code review, Greptile, human triage / stale-bot automation
The gap: Existing AI reviewers review code quality; none act as a maintainer-side contribution gate that enforces a project's declared AI policy, flags low-effort/unverifiable submissions, and requires submitter-side proof (repro, test, video walkthrough) before any human time is spent.
Why now: The LLM contribution flood is a 2025–26 phenomenon: major projects (QGIS now, others considering) are enacting blanket bans as a stopgap precisely because no tooling exists to ration reviewer attention, and maintainers publicly say they'd rather keep contributing open if filtering were cheap.
Moat to build toward: Policy-as-code rule sets tuned per project plus accumulating labeled data on low-effort vs. genuine contribution patterns across many repos; workflow lock-in once embedded in a project's merge pipeline.

Biggest risk: Detection of AI authorship is unreliable, so the product collapses to a fancy CI linter and buyers churn once incumbents bundle a similar gate into GitHub for free.

First three steps:
1. Build a GitHub Action that scores incoming PRs on effort signals (tests included, linked issue, repro steps, author history, diff/PR-size ratio, AI-style heuristics) and auto-requests missing proof before human review.
2. Ship a policy config file (YAML) so projects declare their AI/contribution policy and the gate enforces it with configurable thresholds.
3. Pilot free with 3–5 mid-size OSS projects, publish before/after maintainer review-time data, then charge for team dashboards and org-wide rollout.

Start by asking me up to five questions about constraints (stack, budget, timeline), then propose the smallest version a paying customer would use, and scaffold it.

Why now

The LLM contribution flood is a 2025–26 phenomenon: major projects (QGIS now, others considering) are enacting blanket bans as a stopgap precisely because no tooling exists to ration reviewer attention, and maintainers publicly say they'd rather keep contributing open if filtering were cheap.

The case against

The red team's strongest objection

The LLM contribution flood is new, measured, and pushing major projects to blanket bans, and existing AI reviewers review code rather than enforce a maintainer-side contribution policy — a real gap, though monetizing OSS maintainers remains the weak link.
