# In the News: September 17, 2026


Detail cofounder Dan Robinson argues that coding agents need better development environments, shared memory across tools, and automated rot prevention. In comments under his post, he reports that Detail's agents fix bugs at about a 45 percent baseline and merge at least 90 percent of proposed codebase-health changes. Neither figure is independently audited.

## 1. A vendor names three primitives coding agents still need

**[Towards Self-Driving Codebases](https://blog.detail.dev/posts/towards-self-driving-codebases/)** · Dan Robinson, cofounder, Detail · Company blog, September 2, 2026

Robinson writes that engineering teams spent the first half of 2026 handing as much work as possible to agents and got "mountains of dubious code, but no tsunami of incredible software" in return. He ranks the development environment ahead of the model and harness as the current bottleneck, and names three primitives the stack still lacks: dev environments agents can exercise end to end, since bugs mostly hide in the integrations and browser flows agents cannot reach; a memory layer that carries a correction across every tool instead of making each new agent repeat the same mistake; and automated codebase-rot prevention. "That's one reason so many software factories are so disappointing," he writes. In the Hacker News discussion under the post, at 63 points and 55 comments roughly three hours after it went up, Robinson, posting under his own account, disclosed two figures absent from the essay: Detail's agents fix bugs at "around 45% baseline, increasing over time," and merge the codebase-health changes they propose, such as deleting dead code, at "very high, at least 90%." Detail sells a product built on this pitch, and neither figure is independently audited.

**Why it matters:** Robinson directs investment toward exercisable environments, cross-tool memory, and automated rot cleanup. His self-reported bug-fix rate also sets a useful baseline: a company built around this approach says its agents still solve fewer than half of attempted bugs at baseline.
