AI Analysis

●●SolidShip ItSolve My Problem

Autonomous agent that finds and fixes code debt while you sleep, still very early.

Strengths
  • •Automated task prioritization and batch execution saves manual prompt engineering overhead
  • •Token budget awareness and scheduling prevents runaway API costs during unattended work
  • •Task reordering UI gives developers explicit control over what the agent tackles first
Weaknesses
  • •No integration with existing issue trackers (Jira, Linear) limits usefulness in mature teams
  • •Early-stage documentation and no visible examples of actual PRs created make adoption risky
Target Audience

Full-stack engineers maintaining multiple repositories or codebases with accumulated technical debt.

Post Description

Hi HN! I use Claude Code a lot, but my token usage is directly proportional to how long I'm willing to sit there prompting it. If I'm not at my desk thinking up tasks and feeding them in, the tokens just go unusued[which i weirdly feel bad about].

over the past couple of days, I hacked on sustn, a tool that scans your repo, figures out what needs fixing on its own (dead code, missing tests, security issues, etc.), and puts it in a prioritized list. Then it just starts working through the list - whether you're there or not.

When it's done with a task, it either creates a PR automatically or waits for your approval - you choose. You can reorder the list to control what gets picked up next, set a schedule (e.g let it run overnight), set a token budget, and add your own tasks manually too.

Still very early but would love feedback.
