When a Claude session hit its usage limit at 80% completion mid-debugging, the author used Capacitor — an event-log-based session recorder — to hand off the work to Codex (a different vendor's agent). Codex read only the tail of the final turn (0.4% of the original 17.8M tokens) to identify the exact continuation point, finished the work in 15 minutes for $0.16, and the PR merged on schedule. The key insight is that Capacitor stores sessions as immutable, append-only, vendor-neutral event logs, enabling precise context retrieval and seamless agent handoffs across vendors without re-explaining anything.

How can I resume an AI coding agent session after hitting a usage limit without losing context?
By recording agent sessions as an immutable, vendor-neutral event log (transcripts, tool calls, diffs), a different agent from a different vendor can query just the tail of the log to find the exact continuation point and resume work, rather than replaying the entire transcript. In one case, a Codex session recovered a Claude Code session's progress using only 67.4k tokens versus the original 17.8M tokens, for about $0.16. Developers hitting agent usage limits mid-task can compare handoff and continuity approaches on daily.dev.
