Independent use will determine whether session-migrate can resume active coding-agent sessions across Claude Code, Codex, Pi, OpenCode, and Copilot CLI without losing task-critical context.

What is this?
Session-migrate is presented as a tool by xhluca for transferring an active coding-agent session from Claude Code into Codex, Pi, OpenCode, or Copilot CLI. The supplied results establish that these agents persist sessions in differing formats and that cross-tool continuity is a real problem: transcripts may survive while in-context working state and tool-use context do not. Similar tools such as `continues` claim to discover sessions across multiple agents and generate structured handoffs, but the snippets provide no independent testing of session-migrate itself or evidence that it preserves task-critical context reliably.
Why it matters to Scott
The radar already tracks the same practical test—cross-harness coding-task continuity and context preservation—on `radar:contexo-cross-agent-handoffs`, so session-migrate is another implementation rather than a new thesis. It still bears directly on Scott’s resumable job-control work and his distinction between transcript transfer and a fresh worker recovering task-critical state, making independent testing potentially actionable despite low publishing novelty.

Interpretation history
2026-08-26T22:37:54Z
After 48 hours, the release has drawn only negligible repeat engagement and no independent use, implementation uptake, or evidence of task-critical state preservation. The implementation has faded without advancing the existing cross-harness portability thesis.
2026-08-24T21:34:47Z
No independent use or implementation evidence has arrived, so the case remains an unvalidated implementation of the existing cross-harness portability thesis rather than evidence of reliable task-state preservation.
