dsh-anthropic-membership

If you already have a Claude Pro or Max subscription but have been driving DeepSeek Harness through an API Key, this plugin was built for exactly that workflow. It reuses the same Anthropic membership OAuth grant (isSubscription: true) that Claude Code uses, so no API Key is required at all. From Settings, a single Sign in with Claude Pro/Max click connects any anthropic or claude-* model.

What actually keeps a long session from freezing are two unlocks. First, Anthropic enforces a 2000 px long-edge cap on multi-image requests while DSH stores images at 2048 px; once you cross the limit every retry resends the same bloated history and the session stalls. The plugin down-samples outgoing images to a 2000 px long edge before the request leaves. Second, when the live prompt has already exceeded the model window (1 M-token scale), DSH's summarizer replays that same prompt and fails with Compaction could not produce a useful summary. This plugin slims the compaction call by dropping images and reasoning traces and truncating oversized tool text so that /compact can finally land.

The composer dock keeps a persistent Claude chip showing 5-hour and weekly plan-window percentages plus DSH message counts, and the Anthropic card mirrors the plan-window figure. A bundled macOS chrome-less app window (Helixboard-style) lets you drag DSH onto the Dock for one-click launch; the dock also exposes a Codex slot that lights up when an openai-codex grant exists and a Full access switch that flips the live session's permission preset. If you already subscribe to Claude and lean on DSH as your primary front-end for multimodal, long-context work, this plugin is essentially a must-have.
