Errors
Here's a line from the top of one of my transcript files:

{"parentUuid":"d7331f14-ea4e-4b2c-a3fc-e3080bad9921","isSidechain":false,"attachment":{"type":"deferred_tools_delta","addedNames":["AskUserQuestion","CronCreate","CronDelete","CronList","EnterPlanMode","EnterWorktree","ExitPlanMode","ExitWorktree","Monitor","NotebookEdit","PushNotification","RemoteTrigger","TaskCreate","TaskGet","TaskList","TaskOutput","TaskStop","TaskUpdate","WebFetch","WebSearch"],"addedLines":["AskUserQuestion","CronCreate","CronDelete","CronList","EnterPlanMode","EnterWorktree","ExitPlanMode","ExitWorktree","Monitor","NotebookEdit","PushNotification","RemoteTrigger","TaskCreate","TaskGet","TaskList","TaskOutput","TaskStop","TaskUpdate","WebFetch","WebSearch"],"removedNames":[]},"type":"attachment","uuid":"ebae11f6-61ba-46e2-8f7a-e002b15ff68d","timestamp":"2026-04-28T02:02:16.220Z","userType":"external","entrypoint":"cli","cwd":"/home/qeela/factsandoreos/FeedsNSpeeds","sessionId":"9d10b635-2aab-4743-8df3-614165f30215","version":"2.1.120","gitBranch":"main"}

Glob and Grep are not present. System does have ripgrep installed and Claude can invoke it through Bash

I also have a transcript from where the error first occurred:

When I try to resume that conversation I get an error message:
