Integration details
Description
brief bar is an open, versioned standard for digital product briefs: the rules a brief must pass before a team can quote on it, with their weights, a gate and an acceptance threshold. This connector gives Claude the bar itself. Claude reads the live rules, gets the service judge's own prompt, judges your brief with its own model, and sends the verdicts back. brief bar's open-source code checks every verdict (each rule exactly once, quotes copied verbatim from the brief) and computes the score, the gate and the decision with the same engine the hosted service uses. It also offers a brief template built from the rules, a gate-first improvement prompt, and fast deterministic checks (contact details that break anonymity, a stated budget and timeline, unfilled placeholders, missing sections). Free, no account, no API key. welance runs no language model for this connector: your client's model does the judging, so the result is advisory and labelled as client-judged. Write briefs in any language. Open source: https://github.com/welance/perfect-brief. Rules: https://briefs.welance.com/rules.html.
