SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents context overflows and wasted time by guiding users to convert heavyweight attachments into cheaper, usable artifacts before asking Claude Desktop to analyze them.

Core Features & Use Cases

Conversion-first guidance: Steers Claude Desktop away from raw PDF/DOCX/PPTX/XLSX ingestion and toward smaller markdown or CSV exports.
Artifact selection by file type: Recommends the most effective converted format (markdown for documents/slides, CSV or per-sheet CSV for spreadsheets).
Quality-aware indexing: After the converted artifact is provided, helps create a quick index (sections/slides/sheets, counts, and extraction-quality flags) before deeper analysis.
Common use case: Turning an XLSX into one CSV per sheet (or a small representative sample with sheet names) to enable accurate summarization, extraction, and review without blowing context limits.

Quick Start

Ask Claude Desktop to analyze a heavy attachment by first requesting the converted markdown or CSV artifact instead of uploading the raw file.
