dsh-turn-cost

DSH already shows token usage, cache hit rate, and inference speed in its status bar, but it never tells you the one number that actually matters: how much this turn cost, and how much the whole session has accumulated. dsh-turn-cost fills exactly that gap. It appends a cost pill to the session stats row below the input and another to each turn action row. Clicking either opens a breakdown priced at DeepSeek official API rates, split into three buckets — cache-hit input, cache-miss input, and output — each with its token count and amount. Peak and off-peak pricing is applied automatically based on the request timestamp, and historical price versions are versioned so old sessions are billed at the rate that was in effect when they ran.

Subagents are the second pain point. A single main conversation can fan out to multiple subagents, each billed independently, and there is no built-in way to see at a glance where the money actually went. The plugin aggregates the cost of all descendant sessions (including grandchildren) via the official session list. Inside the dialog, a minimal pager walks you through a totals page, the main Agent page, and one page per subagent, with a tag showing how many subagents are included and which turn each one belongs to. Navigation supports mouse clicks, arrow keys, and Enter to cycle; if the subagent count changes, the current page clamps automatically so you never land on a blank one.

Under the hood the plugin modifies no DSH source code, replaces no native elements, and hides nothing. It registers a session projection unit through DSH's public projection seam and appends its own nodes into two list slots, pulling colour values from the DSH theme. On uninstall both pills and the projection vanish cleanly with no residue; any internal failure simply degrades to self-hiding without affecting DSH itself. It is built for developers who use the DeepSeek API through DSH daily and want a quick, transparent read on per-turn and per-session spend.
