One PR every morning to make your AI assistant better.

Basalt analyzes yesterday's conversations, detects what went wrong, and sends one high quality PR — automatically.

How it works

Step 01

Connect your observability

Plug in Langfuse, Braintrust, Datadog, or any trace source. Basalt ingests every conversation your users had — automatically, every night.

Step 02

Basalt detects what went wrong

Claude analyzes your traces overnight. It clusters conversations, identifies failure patterns, and pinpoints exactly which interactions reveal quality gaps.

Error pattern detected — 34 affected conversations

Step 03

One PR. Every morning.

Basalt generates a targeted fix — prompt update, tool definition, or system instruction — validated against your golden dataset before it ships.

fix: improve handling of ambiguous queries (34 affected sessions)

Your users' real behavior is the signal. Basalt reads what actually happened yesterday — and sends one high-quality, testable PR to your repo every morning.

What Basalt improves

System prompts

Rewrites or extends the instructions your agent follows — targeting the exact failure pattern detected.

Tool definitions

Updates how your agent calls external tools — fixing parameter errors, missing context, or wrong call sequences.

Few-shot examples

Adds or replaces examples in your prompt to steer the model toward the right behavior on the patterns that failed.

It never breaks what's already working.

Before every PR is opened, Basalt runs your fix against your golden dataset — the handpicked examples that define correct behavior. If anything regresses, the PR is blocked.
