Hono Agent DX

Measure and improve the developer experience of coding agents using Hono.

Adoption

Given a neutral prompt — no framework named — does a coding agent choose Hono? Hono adoption rate and the most-chosen option, per runtime × scenario. Click a cell for history and details.

Value

Is Hono worth using when an agent writes the code? Same task, same acceptance spec, same model: a project with no framework (the agent writes a raw fetch handler) against a project with Hono in package.json.

Experiment of 2026-09-06 · 10 runs per cell · claude-haiku-4-5 · success, median tokens, median duration, median lines of code written. Not yet part of the weekly schedule.

Practical

Hand the agent a real Hono project and a change request, grade the result with hidden deterministic checks. Success rate, median tokens, median duration, and CLI usage per task — with and without the Hono CLI and skill.
