DSH (DeepSeek Harness) plugin · bill

Key features

• Per-turn cost — one line under every finished turn: what it cost, how many steps, the cache-hit rate.
• Every other plugin ships a built-in table of 2–4 DeepSeek models, which means no prices at all once you switch provider — and which is why they all need a "edit the price table by hand" entry point.
• two catalogues, models.dev and OpenRouter, cached for 24h and written to disk, falling back to a built-in historical snapshot on failure
• Under prefix caching the first N tokens of the prompt bill at the cache rate and the rest at full rate — on DeepSeek the two differ by up to 156×.
• It reads the session log itself, so turns from before you installed the plugin are covered too.
