# Claude Code 2.1.299 By Steven Van · 2026-10-14 Idle terminal conversations of 200K or more tokens now compact before the one-hour prompt cache expires. [Claude Code]() 2.1.299 adds CLAUDE\_CODE\_DISABLE\_FILE\_MENTIONS, an environment variable that gives Claude the paths of @ file mentions to read with its file tools instead of supplying the files’ contents. ## Idle compaction in the terminal A conversation with 200K or more tokens left idle for about 54 minutes is now compacted before its one-hour prompt cache expires. This avoids reprocessing the entire conversation when the next message arrives. CLAUDE\_CODE\_IDLE\_COMPACT\_MIN\_TOKENS changes the 200K-token minimum, while setting "idleCompaction": false in settings.json turns idle compaction off. Both controls require version 2.1.290 or later. ## New APIs for managed mods - $.prompt.media lets a prompt.submit hook in a mod installed by managed settings read the bytes of an image or document attached to the prompt. - $.session.identity() lets those mods read how the session is signed in. It also provides the organization and email when managed forceLoginOrgUUID lists that organization. - A mod’s Text gains size, weight, mono and tabular options, and its Box gains named spacing steps from xs to xl. The bold option is deprecated in favor of weight. ## Time to finish runner work on shutdown The [release notes]() also add --shutdown-drain-sec to the claude self-hosted-runner orchestrator. On SIGTERM, it stops polling and gives the poll in flight and running spawn hooks up to the specified number of seconds to finish. ![Claude Code]() Claude Code Anthropic's agentic coding tool — Claude in your terminal, IDE, desktop app and browser, reading and editing your codebase, running commands, opening pull requests and working on tasks in the cloud.
