# SKILL: asset-sourcing — REAL data/assets, provisioned, never placeholders Rule (P-11 with teeth): before using any EXTERNAL datum or asset the product needs, obtain the REAL source and PROVISION it automatically. If there is no source, ESCALATE; never fall back to placeholder/mock/initials/empty data without DECLARING it. Applies to ANY domain (P-10). ## Scope (any domain) Covers EVERY external asset/datum the product requires, not just code or art: - datasets and reference tables/registries - typefaces (fonts) - icons and art - models - lookup tables / reference files ## Provisioning pattern (mandatory) 1. **Fetch script** (e.g. `scripts/fetch-assets.*`) that downloads the REAL source to the exact path where the code consumes it. 2. **Wired into `build:all`** BEFORE the build step → provisioning is NOT a manual step for the PO. 3. **Idempotent:** cache + verify integrity; if it already exists and is valid, do not re-download. 4. **DECLARED fallback (P-11) + explicit error (P-06):** if a download fails, a clear error (which source, what happened) and DECLARED degradation (the missing datum is marked as such; the lookup/resolver returns an honest empty) — NEVER a placeholder that looks real, nor a silent failure. 5. **License attribution:** record each source's license in a `NOTICE` file. 6. **No runtime CDN dependency (P-02):** the asset is bundled/cached LOCALLY. ## Environment note The agent's environment may be unable to download (network limits).
