What belongs in a note?
Whatever will save the next person time: reproduction steps, a hunch, a decision, or a link to the pull request that fixed it. Keep the useful trail where the error already lives.
The error remembers what happened
A clue in chat is gone by next week. Keep notes, files, ownership changes, resolutions, and reopenings beside the error, so the next person gets the whole story without hunting for it.
Can I attach the messy evidence?
Yes. Add screenshots, logs, and other files instead of describing them from memory. They stay with the note and are there when the error comes back months later.
Do I have to keep the history up to date?
No. Telebugs records ownership changes, resolutions, and reopenings for you. Add a note when human context matters, and the rest of the story keeps writing itself.
Can I point someone to one specific update?
Yes. Every note and activity entry has its own link, so you can send a teammate straight to the useful part.
