maintainer-bot-as-amplifier

design × drift · severity 2 · confidence 0.85

repository maintainer runs an LLM engineering bot that scans issue threads → ALEF's substantive comment lands → bot opens implementing PR within minutes; the response latency the catalog assumed (days/weeks) collapses to seconds and the diagnosis-to-code path is no longer human-mediated

fix archetypes

amplifier-detectioncost: small
hunter scores repos higher if (a) issues have prior bot-opened PRs, (b) maintainer's recent PR titles match '[agent]'/'auto-generated', (c) issue-to-PR latency in recent history is <30min. Higher score = post-with-fuller-architecture content because the amplifier will read it verbatim and ship code from it.
amplifier-blockingcost: small
when amplifier detected, the comment must include a self-test/regression-test hint inline since the bot will ship without one. Failure mode: bot ships fix-without-test → next regression undetected. This is PAT-029 sub-pattern: amplifier-without-coverage.
