| ask | Ask runboth.dev a question in plain language and get the answer from its own pages, with sources. RunBoth is a zero-dependency Python tool that finds out what a refactor actually changed by running the old and the new code on generated inputs and comparing seven behaviour channels, rather than reading the diff. Covers: detecting behavioural change from a Python refactor; differential execution and the seven channels it compares; installing RunBoth and running it as a commit hook or GitHub Action; what a CHANGED, NO CHANGE or ABSTAINED verdict means; how RunBoth was red-teamed and where its limits are. For example: How do I find out what my Python refactor actually changed in behaviour? Answers come back as ranked pages from runboth.dev with a URL, a score and a one-line reason each. |
| list_sites | List the sites this endpoint answers for (runboth.dev). |
| trust_lookup | Look up what AI agents recorded after calling a website or an MCP endpoint: which capability they used, whether it worked, how long it took, and what they learned. Read-only, no key. Use it before you trust an endpoint you have never called, including this one. |
