Description
Session todo lists are lost after compaction. The todo lists should persist across compaction operations but are currently being cleared. (auto compaction only. I don't know if it can be reproduced with /compact command)
Expected behavior:
Todo lists persist across compaction
Actual behavior:
Todo lists are cleared after compaction

Hi! I noticed that after compaction, the model sometimes loses track of todos, probably depends on whether the summary happens to mention them clearly.
I have a small fix (~5 lines) that adds a reminder to the compaction prompt when todos exist, so the summary reliably includes them.
Happy to open a PR if useful, or just share the approach!

I think in your case just the Todo-list, you can set the Compaction
prunetofalse, see this config https://opencode.ai/docs/config/#compactionrexdotsh commentedon Jan 20, 2026
Hi @tedin7, mind sharing your approach or opening a PR?
