Bug Description

When sending an image via Telegram to Hermes Agent, the vision_analyze tool cannot read the image even though it exists in the local cache.

Environment

  • Hermes Agent v0.13.0 (2026.5.7)
  • macOS (Apple Silicon)
  • Vision provider: Gemini (via hermes config set vision_provider gemini)
  • Platform: Telegram gateway

Steps to Reproduce

  1. Send an image via Telegram to Hermes bot
  2. Ask Hermes to analyze the image
  3. vision_analyze tool returns "cannot see image"

What Works

  • Image file exists in ~/.hermes/image_cache/ (confirmed 57KB JPEG)
  • HTTP server can read the image
  • base64 encoding succeeds

What Fails

  • vision_analyze: cannot see the image
  • browser_vision: also fails

Expected Behavior

Hermes should be able to analyze images sent via Telegram gateway.
