Token usage #22

Hello,

First of all, Thank very mush you for this repo.

I used the opencode with Anthropics API way for a while on opencode but it become quickly unsustainable, hence I thought I'd give this plugin a try today. (After a week of trying Claude Code)

It works nicely but one thing I noticed is that I burnt trough 20% of my 5h hours usage in single message, something I almost never achieve in claude code even on way more complicated tasks. (The same question resulted in 3% of 5 hours usage on Claude Code)

I wonder if this has to do with #17 or #19 ? or something related to caching that claude code use (along with opencode + Anthropics API) but this plugin omits ?

Also, Anthropics saying to be that I burnt trough 20% of my 5 hours usage, while opencode reporting a cost of only 2$ (I strictly use Opus 4.8 max), so I'd imagine that reporting is mostly false ?
