Claude Code Session Jsonl Orphan Advisor Tool Result

About this skill

Repair a Claude Code session whose transcript JSONL has an orphan servertooluse / toolresult content block, causing every API call (including /compact and claude --resume) to fail with HTTP 400 "unexpected tooluseid found in advisortoolresult blocks: srvtoolu... Each ... block must have a corresponding servertooluse block before it". Use when: (1) a Claude Code session dies mid-advisor call with "socket connection was closed unexpectedly", (2) resume / compact returns the 400 above naming srvtoolu..., (3) /remote-control (or any system event) activated mid-stream while the assistant was emitting an advisor response. Covers diagnosis via grouping JSONL lines by shared message.id, surgical deletion of the orphan pair (both halves), and the line-number-drift gotcha that occurs when the file grows between inspection and edit.
