Usage 0.29.28

If you want your Starship prompt or tmux status bar to show remaining AI quota, you no longer need to write custom Python scripts importing usage's internal modules. The new usage status command prints a concise one-line summary, and --json outputs a versioned JSON payload. Both read the same local files as the menu bar item, requiring zero network calls. Ready-made snippets in the development documentation make setup immediate. It is like a utility meter on a house: instead of calling a technician to disassemble the mechanical counter inside, a digital readout on the front now lets any display read current consumption without contacting the utility company.

When downloading release artifacts, you can now mathematically verify that your binaries were built directly from official source code. Every macOS and Windows release artifact now ships with a signed SLSA build-provenance attestation, verifiable in your terminal using the gh attestation verify <file> --repo aqua5230/usage command. In addition, the macOS release includes a CycloneDX software bill of materials (SBOM) detailing every bundled dependency. It is like buying packaged organic food: the box carries a certified supply-chain tracking seal proving the product was never swapped in transit, alongside a complete ingredient list that reveals every sub-component inside.

When your network is down or upstream price lists cannot be reached, model cost calculations will no longer silently drift on outdated rates. When usage cannot fetch live pricing, it falls back to a built-in pricing table. That built-in table now records the exact date it was last synced against upstream and writes a warning to the log whenever it is engaged, making stale pricing immediately visible before it skews your cost totals. It is like an exchange counter whose electronic rate board goes dark: the teller pulls a printed rate sheet from the drawer, but the sheet now displays an inspection date stamp and a written notation is logged on the slip, ensuring no one calculates totals under the mistaken impression that prices are current.
