Using Claude hosted agents to solve open source bugs and perf improvements

JAIPilot, an AI tool that optimizes changed Java code with proof, reports that its Claude-powered hosted agents produced 60 live pull-request drafts and 33 safe no-changes across an audited 95-run campaign on public open-source projects, with 0 auto-merges. The tool's improvements were adopted upstream in OpenTelemetry PR #8684, cut Micrometer runtime by 43% (14.904 to 8.482 µs/op) and allocation by 57% (18,616 to 8,000 B/op), and fixed a Maven Deploy race reproduced 5/5 times in baseline versus 15/15 correct in candidate. JAIPilot is free for public open source with 10 eligible evaluations per GitHub account or organization.

JAIPilot App Tags 2 Pricing Select a tab navigation JAIPilot optimizes changed Java code—with proof. It works on the exact pull-request head, runs focused tests and the real Maven or Gradle build, then opens one validated companion draft. No proof, no PR. One small improvement. Repository-native proof. JAIPilot improves only changed production paths, publishes against the feature branch, and never auto-merges. Failed identity, tests, build, or evidence means no PR. Full audited results: all 60 live drafts, 33 no-changes, costs, and limitations https://github.com/JAIPilot/jaipilot/blob/main/CLOUD RESULTS.md . OpenTelemetry: adopted upstream Removed redundant timeout scheduling from synchronous export: 1 schedule/cancel pair → 0 . The contributor adopted it into upstream PR 8684 https://github.com/open-telemetry/opentelemetry-java/pull/8684/commits/acca5b7d5553b59a228e3322183e131cae4f53af . 32 focused tests; 161 build tasks passed. Draft https://github.com/skrcode/opentelemetry-java/pull/2 . Micrometer: 43% faster, 57% less allocation Removed per-call HashSet work: 14.904 → 8.482 µs/op and 18,616 → 8,000 B/op . 75 focused tests and both affected module builds passed. Same-host JMH over 200 rows. Draft https://github.com/skrcode/micrometer/pull/2 . Maven Deploy: atomic cache initialization Atomic initialization removed duplicate full-reactor scans. A 16-thread regression reproduced the baseline race 5/5 ; the candidate produced exactly one scan 15/15 . 29 tests, Checkstyle, RAT, and the clean offline build passed. Draft https://github.com/skrcode/maven-deploy-plugin/pull/2 . JavaParser: terminate cyclic traversal Shared-node expansions fell 2 → 1 ; a cycle fixture went timeout → ~20 ms . The full reactor passed 2,094 tests . Draft https://github.com/skrcode/javaparser/pull/3 .
