Visual Language Gateway Plugin

Key features

• Each picture is described only once: In-process LRU cache by attachmentId, retry, context compression, and subsequent rounds reuse the same description without repeated billing.
• dsh-deepseek-vision is a visual language gateway plug-in for DeepSeek Harness.
• Paste/drag the image → The configured visual model is first described in text (extract code, error reports, logs, UI copywriting, and describe the layout verbatim)
• compactionBy default, the session provider (i.e. gateway routing) is inherited, the image is rewritten and the cache is hit
• Session invariant retentionThe original image is still persisted in the session log, and history/playback/reconstruction are not affected.
