ACP permissions correlate with tools and stable v0.64.0 reports usage. Since v0.62.0 ACP clients receive a pending tool_call update before permission requests and a failed update on denial; MCP titles separate the explanation. v0.63.0 resolves sessions before initialization and avoids same-minute filename collisions. Stable v0.64.0 adds PromptResponse.usage fields for input/output/cached-read/thought tokens, usage_update turn/context notifications, and exact-ID session recovery with listener cleanup. The PR’s approximate billing savings were not measured here.
Channel: tagged-release. Half: capability. Date: 2026-09-29.
Operator consequence: Editor adapters on 0.64.0 can correlate permission requests with tools and consume usage/context reports without a preview dependency. Recheck request IDs, denial completion and resumed-session identity in the adapter. Use the reported usage for observability, not as independent proof of claimed savings.
