ccusage-adapter-pi

The Pi adapter: it turns Pi agent stores, including additional named stores from the config file into the usage entries the reports render.

Owns

• loader.rs — reading the source, dedupe, and date filtering.
• parser.rs — raw record parsing, token mapping, and model naming.
• paths.rs — environment variables, default directories, and file discovery.
• report.rs — the JSON and table shapes where they differ from the shared ones.

Anything that is not specific to this source belongs in ccusage-core or ccusage-adapter-common instead.

Data source

• ${PI_AGENT_DIR:-~/.pi/agent/sessions}, plus any pi.stores[] entries in ccusage.json

Record shapes, token mapping, and cost rules are documented in src/README.md.

Reads plain files through ccusage-adapter-common, which handles walking, size-balanced chunking, and ordered parallel reads.

Build layer

Built in the adapters Crane artifact layer; the layer compiles all adapters in one Cargo invocation, so they build concurrently.
