Agent Cost Ledger Normalizer

Scenario

Use when model usage, tool usage, task ownership, and provider prices live in separate logs and a team needs one reproducible ledger.

Input and output

Input contains redacted usage rows with run id, agent id, input units, output units, tool units, and unit prices. Output has per-run costs, aggregate totals, and a stable ledger_hash.

Execution and recovery

Run the README command. Missing numeric fields, negative units, or missing prices return a visible error. This script does not infer provider prices or fetch billing data.

Privacy boundary and acceptance

Use identifiers and numeric summaries only; omit prompts, private payloads, keys, cookies, and customer content. The sample produces a non-empty hash and repeatable totals.
