Tools

• aggregate_verdicts ~381 tokens
  Turn your model's verdicts into the bar's score, gate and decision. Advisory. Validates the verdicts against the live ruleset (every rule exactly once, valid status and confidence, the version you judged at) and against the brief (each quote must be copied verbatim), then aggregates the
• bar_status ~92 tokens
  Which ruleset version is live, and what this free surface can do. Confirms the mode (bring your own model, zero provider calls, no fallback to welance's model) and the tools available.
• check_brief ~234 tokens
  Deterministic checks only — semantic coverage is INCOMPLETE. Never a score. Finds what a pattern can find for certain: emails, URLs and phone numbers (which block anonymisation), a stated budget and timeline, personal-data cues without a compliance cue, unfilled placeholders, the title
• get_brief_template ~110 tokens
  A brief template built from the live rules, with the inputs each section needs. Use it to start a brief from nothing, or to see which section a gap belongs in. Markdown, one section per rule, gate rules marked; write in any language.

  A working order for improving a brief with your own model, gate first. Pass the verdicts you already have (the JSON array from your model) to target the failing rules in weight order; without them the prompt walks every rule. The prompt keeps the author's voice and forbids invented
• get_judge_prompt ~206 tokens
  The judge prompt and verdict JSON Schema, for YOUR model to answer. Free. This is the service judge's own prompt, word for word, so your model grades against the same bar. Pass the brief to get it embedded, or leave it empty for a template with a {{BRIEF}} placeholder. Answer the prompt
• get_rules ~160 tokens
  Read the bar before judging anything. Free; no model runs. Returns the live catalogue with its version: every rule's id, title, criteria (what the judge reads), weight, gate role, policy context and how to pass it, plus the arithmetic — status scores, confidence threshold, accept th
