Coding Agents · Suite 0.1.0
Add a feature plus tests to a seeded repo
The agent gets the TaskBoard repo at a pinned commit and a written feature spec. It may edit application code and add tests. A hidden suite the agent does not see decides the pass.
In one paragraph
ShipRanked has not published a score for “Add a feature plus tests to a seeded repo.” 6 tools are queued, in alphabetical order: Aider, Claude Code, Cline, Cursor, Devin Desktop, GitHub Copilot. That order is not a ranking. A published score will be the median of three runs, from 0 to 100. Task success is 40%, output quality is 20%, and speed, cost, effort, and consistency are 10% each. The top 3 stays empty until three runs per tool are in and none of those runs are older than 60 days.
The task
Add the feature described in the task spec to the pinned TaskBoard commit, including tests that cover the new behavior. Do not rewrite unrelated parts of the app.
TaskBoard, a Next.js and Postgres repo tagged per suite version. The repo is not published yet.
Acceptance checks
- Hidden unit and end-to-end checks for the feature pass
- Typecheck and lint pass
- Tests that shipped with the seed repo stay green
