As AI tools make it trivially easy to generate plausible-looking pull requests, open source maintainers face a growing signal-to-noise problem in identifying contributors worth mentoring. The '3 Cs' framework offers a strategic filter: Comprehension (does the contributor understand the problem?), Context (do they provide what reviewers need, including AI disclosure?), and Continuity (do they keep coming back?). Only contributors who demonstrate all three warrant deep mentorship investment. This approach protects maintainer time, preserves the multiplier effect of mentorship, and reduces bias by replacing gut feelings with a clear rubric. Practical implementations include requiring issues before PRs, adding AGENTS.md files, and AI disclosure policies.
