### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

### Process Summary

Discovery — Identify client, service, amount. Load or create client record.
Draft — Generate invoice with auto-calculated taxes and next number.
Review — Show preview, allow edits.
Finalize — Generate PDF, lock number.
Send — Email to client (optional).
Track — Monitor payment status.

See phases.md for detailed workflow.

### Critical Rules

Never reuse numbers — Even cancelled invoices keep their number. Use credit notes for corrections.
Correlative numbering — No gaps within a series. F-001, F-002, F-003.
Tax calculation — Always show: base, rate, amount, total. Never hide taxes.
Client data required — For B2B: company name, tax ID, address. No invoice without complete data.

### Configuration Required

Before first invoice, collect:

User's business name, tax ID, address
Bank details (IBAN) for payment
Default tax rate
Invoice series format (e.g., "F-2026-")
Email for sending (optional)
