It is off by default; run `/optchat on`, `/optchat off`, or `/optchat status` in a root session. In an enabled session, each turn sees a constant-size view of the whole chat, made of one-line summaries, plus the new message. The model can open any line with the `zoom` tool and read message times with `date`. Optchat does not apply to subagent sessions. Memory is stored in `~/.local/share/opencode/optchat//`. Compactions run in a child session named "optchat compactions". The plugin accepts two options: `compactionModel` (default `opencode/claude-haiku-5-5#xhigh`) and `dataDir`. + ## Local installation From a local checkout, run: diff --git a/install-local.sh b/install-local.sh index a022e69..1aa0683 100755 --- a/install-local.sh +++ b/install-local.sh @@ -2,8 +2,8 @@ set -euo pipefail selection=() if (($#)); then - if [[ "$#" -ne 2 || "$1" != "--plugins" || !
