# Variable promptHistory`Const`

```typescript
promptHistory: {
    listSessions: (
        args?: PromptSessionListArgs,
    ) => Promise<PromptSessionListResult>;
    readSession: (
        store: PromptHistoryStore,
        key: string,
    ) => Promise<PromptSessionDetail>;
} = ...
```

Types: [PromptSessionListArgs](../interfaces/core.PromptSessionListArgs.md), [PromptSessionListResult](../interfaces/core.PromptSessionListResult.md), [PromptHistoryStore](../types/core.PromptHistoryStore.md), [PromptSessionDetail](../interfaces/core.PromptSessionDetail.md)

Read-only local agent transcript access. Main only exposes known Codex and Claude Code JSONL roots, and `readSession` accepts the store-relative keys returned by `listSessions`; projects never provide absolute filesystem paths.

Requires `"read"` in manifest `requests.promptHistory`.
