Probative
An evidence-grounded, multi-agent product discovery toolkit. It reads your documents, research and delivery history, then writes discovery artefacts in which every claim cites its source or is labelled a hypothesis with a test attached.
It runs as a CLI, an MCP server, a Claude Code plugin and a GitHub Action that critiques the specs a pull request changes. Built phase by phase, in the open from the first commit.
Try it once, nothing to undo
$ uvx probative --version
$ uv tool install probative
# or inside Claude Code
/plugin install probative --marketplace vedm1/probative

House rules
- Every claim has a source, or it is a hypothesis with a test.
- Real functional agents, with a critique layer built into the flow.
- Stories export to Jira and Azure DevOps.
- Never as tedious as a spec kit nobody keeps up to date.
