SST OpenCode v1.15.5: Experimental OpenAI Runtime Path, --replay Session History
SST
SST OpenCode v1.15.5 (May 18) introduces an experimental OpenAI native runtime path (preview), adds `--replay` and `--replay-limit` flags to view recent session history during interactive runs, fixes plugin tools using the `ask` function so tool calls complete correctly, reduces subscription race conditions causing missed /event updates, sorts the v2 session list by most recently updated, and refreshes the TUI prompt layout after pasting content.
Why it matters
The experimental OpenAI runtime path is a significant architectural addition for users running OpenCode against OpenAI's infrastructure. The --replay flag enables debugging and auditing of past agent sessions without leaving the TUI.
