file-sharing

## Instructions When you need to share a file with the user (chart, export, report, comparison table): 1. Create the file in `/tmp` using `code_interpreter` 2. Include the **absolute path** (e.g., `/tmp/claims_summary.csv`) in your response 3. The frontend will automatically convert the path into a downloadable link 4. Do NOT base64-encode file contents into the chat ## Insurance-Specific File Types - **Claims exports** (.csv) — claims data, status reports, loss summaries - **Policy comparisons** (.csv, .md) — side-by-side coverage comparison tables - **Coverage summaries** (.txt, .md) — plain-English policy summaries - **Charts and visualizations** (.png) — claims trends, loss ratios, geographic distribution - **Regulatory reports** (.csv, .md) — compliance checklists, audit findings ## Security - Always mask sensitive policyholder data (SSN, full policy numbers) in exported files - Show only last 4 digits of policy numbers where possible - Include appropriate disclaimers on any exported coverage summaries ## Constraints - Files must be written to `/tmp` - Files are ephemeral — they do not persist across container restarts
