# EDEN telecom skill

## When to use
- Building/extending the SaperX adapter → `references/saperx.md`.
- Modeling usage-based billing (CDR/consumption feeding `usage_charges`) → `references/usage-billing.md`.

## Rule
Never couple internal entities to SaperX's raw payload — always a normalized DTO + `external_id` + origin snapshot (ADR-0010). If an endpoint isn't available/documented, build interface + mock + explicit TODO, never a fabricated response.
