# ccusage-adapter-gemini
The Gemini CLI adapter: it turns chat JSON and JSONL files
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
- `${GEMINI_DATA_DIR:-~/.gemini}/tmp/**/chats/*.{json,jsonl}`
Reads plain files through `ccusage-adapter-common`, which handles walking,
size-balanced chunking, and ordered parallel reads. Antigravity SQLite data is
owned by the standalone `ccusage-adapter-antigravity` source.
## Public surface
- `loader::load_entries`
- `report::report_from_rows`
- `report::summarize_entries`
- `run`
## Depends on
- `ccusage-adapter-common`
- `ccusage-core`
- `jiff`
- `serde`
- `serde_json`
## Build layer
Built in the `adapters` Crane artifact layer; the layer compiles all adapters in one Cargo invocation, so they build concurrently.
