What problem does it solve? It gives you a local, verifiable record of shipped work and AI token spend, so every value claim about AI-assisted development traces back to checkable events instead of estimates. ## Core Features & Use Cases - Ledger initialization and health checks: Set up the ledger home, seed identity and pricing, and run integrity and conservation verification with the bundled CLI. - Append-only event storage: Read and write work entries, usage events, session receipts, and corrections across monthly-sharded JSONL streams with deterministic ULIDs. - Attribution and portability: Pin sessions to tracker keys, export a redacted career ledger, and keep every token conserved and accounted for. - Use Case: After finishing a feature with Claude, ask to log the shipped item with its pre-registered estimate; the skill appends a sealed event, attributes the metered tokens to the tracker key, and the receipt is ready for your next report. ## Quick Start Ask the assistant to initialize your waybill ledger and show what has been logged so far.
