Claude Code calls this endpoint before each request to check conversation size and decide whether to trigger compaction. Without it, the gateway returns 404, Claude Code cannot estimate context usage, and long conversations eventually hit the upstream CONTENT_LENGTH_EXCEEDS_THRESHOLD error (400). The endpoint builds the full Kiro payload and counts tokens on the serialized JSON using tiktoken, consistent with the token counting approach used in the messages endpoint.
