663663* **Wait for the refill**: on Claude Code v2.1.290 or later, an interactive terminal session's limit refills at about 100 calls per hour. To change the rate, set [`CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR`](/docs/en/env-vars#variables) to a number of calls per hour, such as `50`.
664664* **Start a new conversation**: running [`/clear`](/docs/en/commands#all-commands) at the Claude Code prompt also resets the count. If work that can still spawn subagents survives the clear, such as a running workflow, the count carries over instead.

666In [non-interactive mode](/docs/en/headless) with `-p` and in the [Agent SDK](/docs/en/agent-sdk/overview), the limit applies per turn, not per session. A turn lasts from a message you send until Claude finishes responding. The limit resets when you send the next message after that or start a new `claude -p` run, even with [`--continue` or `--resume`](/docs/en/headless#continue-conversations). For more searches, raise [`CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION`](/docs/en/env-vars#variables) or set a refill rate with [`CLAUDE_CODE_WEB_SEARCH_REFILLS_PER_HOUR`](/docs/en/env-vars#variables).

666668## Write tool behavior
667669 
668670The Write tool creates a new file or overwrites an existing one with the full content provided. It doesn't append or merge. Write also overwrites an existing file whose bytes don't decode and saves the new content as UTF-8, as described under [non-UTF-8 files](#non-utf-8-files).
