jardinero

Jardinero is an open-source, self-hostable AI engineer that tends a codebase. It is described as a crew of always-on AI engineers that watch logs, reproduce what breaks in disposable sandboxes, and ship fixes. It runs a factory of small, focused machines, each watching a different door into the codebase and shipping pull requests for review.

Jardinero performs three main jobs. It reviews production telemetry from Grafana logs and metrics every few minutes, scoring signals against an investigation threshold and rejecting noise with a reason. It implements assigned Linear issues by scoping the task, building it in an isolated sandbox, running tests, and handing back a review-ready PR. It also maintains GitHub issues and pull requests when tagged @jardinero, answering review threads with evidence, fixing failing checks, resolving conflicts, and following repo conventions.

Every job happens in a disposable sandbox with a pool running in parallel, and nothing touches branches until the work is green. Jardinero is built by Tenki, part of Luxor, and tends Tenki’s own codebase daily using Tenki sandboxes. It is open source under LuxorLabs, can be self-hosted on a laptop or server, and run reports can land in Discord.
