| description | File router that routes uploaded files to appropriate analysis skills. CSV/Excel/JSON → data-analysis, Images → data-viz, PDF/HTML → data-base. |
Mental Model
Files are routed by type to specialized processors. This skill is the router - detection and delegation, not processing itself.
File Routing
| Extension | Routes To | For What |
|---|
.csv, .xlsx, .json | data-analysis | Statistics, aggregation, patterns |
.png, .jpg, .gif | data-viz | Chart recognition, visualization |
.pdf, .html | data-base | Text extraction, scraping |
Anti-Patterns (NEVER)
- Don't accept non-ASCII filenames (require rename)
- Don't process unsupported file types
- Don't bypass file size limits (50MB default)
Upload Flow
- User uploads file via Web UI
- Detect type by extension/MIME
- Inject metadata into message:
[File: name.csv (id) - Type: CSV, Skill: data-analysis]
- Activate appropriate skill
- Return results to user
Critical Constraints
Filenames MUST be ASCII-only (no Chinese/non-ASCII):
- ✅ Good:
data.csv, report_2025.xlsx
- ❌ Bad:
数据.csv, 報表.pdf
If non-ASCII filename detected, ask user to rename before processing.
