Tasks

Meeting action items

meeting-action-items · v1

Extract action items as a JSON array of owner and task. The deterministic check compares the set of owners only. Wording of the task strings is not scored here; that would be a rubric.

Five-bullet brief

five-bullet-brief · v1

Rewrite a note as exactly five bullets under a word cap. This tier-1 task measures format compliance only. It does not score whether the bullets are accurate.

Earnings call summary

earnings-call-summary · v1

Summarize an earnings-call excerpt into five bullets. The fixture is a short excerpt, not a full transcript, so this version does not measure a 2,000-word run. Scoring is a blinded rubric, not a hardcoded quality score.

Customer changelog draft

changelog-customer-draft · v1

Rewrite internal release notes into a customer-facing changelog. A blinded rubric scores accuracy, clarity, audience fit, and whether anything important was dropped.

Amounts are the exact stored decimal strings. No rounding is applied. candidate_cost_usd is the sum of measured run costs. judge_cost_usd is the sum of stored tier-2 judge ledger rows, or null when none were recorded. total_cost_usd equals candidate plus judge only when every candidate cost is present and a judge cost was recorded.

Candidate costs are the measured amounts on the receipts below (16 runs).
