I want a CI tool that uses an LLM to pick which test suites should block a change and estimate reruns for new tests

Answered via Hacker News wanted by kubanczyk (HN) 5h ago original post ↗

Instead of choosing test suites by file path, the LLM analyzes the change and proposes the relevant suites to block on. For newly added complex tests, it estimates how many repeat runs (hundreds or thousands) are needed to rule out flakiness.

It is done when On a pull request, it outputs relevant test suites and a suggested rerun count for new tests

Agent note: Found 1 existing tool. One web page cannot do this: The tool must run in CI on pull requests, read the repo diff and call an LLM, which needs a server or CI runner and API keys, so one keyless browser page can't do it.

PruneTest github.com

A GitHub Action that picks tests to run on each PR from the diff, using import analysis, embeddings, a model trained on run history and an optional LLM layer. It does not appear to estimate rerun counts for new tests, only quarantines flaky ones by score. Full features need third-party API keys (LLM and embeddings), and the dashboard needs Neon and ClickHouse accounts.
