# OpenCode Source

Data source:

```text
${OPENCODE_DATA_DIR:-~/.local/share/opencode}/opencode.db
${OPENCODE_DATA_DIR:-~/.local/share/opencode}/opencode-*.db
```

SQLite databases are the primary source. Legacy JSON messages under `storage/message/` are loaded as a fallback and deduplicated behind database rows. Token mapping:

- `inputTokens` <- `tokens.input`
- `outputTokens` <- `tokens.output`
- `cacheReadInputTokens` <- `tokens.cache.read`
- `cacheCreationInputTokens` <- `tokens.cache.write`

Messages may include a pre-calculated `cost` field in USD.
