Lua's string.format has a maximum width limit of 99 characters for format specifiers. When position='current' is set, the output window can be very wide, causing the calculated max_desc_length to exceed this limit and trigger an 'invalid conversion specification' error. Fix by capping max_desc_length at 90 characters to stay safely under the 99-character limit.

Summary
Fixes a bug where running
/helpcommand in Opencode withposition='current'configuration triggers an error:Root Cause
Lua's
string.formatfunction has a maximum width limit of 99 characters for format specifiers. Whenposition='current'is configured, the output window opens in the current window with a very large width (e.g., 161 characters). The code calculatesmax_desc_length = window_width - 30, which can exceed 99 and trigger the "invalid conversion specification" error.Fix
Cap
max_desc_lengthat 90 characters to stay safely under the 99-character limit:Testing
position='current'configuration/helpcommand now works correctly without errors
