xAI's grok-imagine-image API returns ephemeral imgen.x.ai/xai-tmp-* URLs that 404 within minutes — long before downstream consumers (Telegram send_photo, browser preview, multi-tier delivery fallback) get a chance to fetch them. The xAI image_gen provider was passing those URLs through unchanged on the elif url: branch; b64 responses were already cached locally via save_b64_image. Result: every image_generate call on a Telegram-routed xai-oauth profile delivered no image, falling through to text-only. Adds agent.image_gen_provider.save_url_image() — a sibling helper to save_b64_image that downloads URL bytes to $HERMES_HOME/cache/images/. Content-type-aware extension inference with URL-suffix fallback; oversize cap (25MB default) with partial-write cleanup; empty-body refusal. Mirrors the audio_cache pattern used by text_to_speech. Wires save_url_image into both the xAI and OpenAI providers' URL branches. When the download fails (network blip, 404 in-flight) we log a warning and fall back to the bare URL rather than turning the tool call into a hard error — the gateway's existing URL-send fallback then gets a chance to surface the original error legibly. Test plan: - tests/agent/test_save_url_image.py — 8 direct tests against a real in-process HTTP server: bytes round-trip, content-type → extension, URL-suffix fallback, default-to-png, 404 propagation, empty-body refusal, oversize cap + cleanup, filename uniqueness. - tests/plugins/image_gen/test_xai_provider.py — flip test_successful_url_response (was asserting the bug), add test_url_response_falls_back_to_bare_url_when_download_fails. - tests/plugins/image_gen/test_openai_provider.py — symmetric pair. 160/160 in the broader image_gen test surface. |
