* A subagent inherits the main session's extended thinking configuration. On earlier versions, extended thinking is disabled inside subagents regardless of the main session's setting.

<Note>
{/* min-version: 2.1.217 */}By default, subagents can't spawn subagents of their own. To let them, set [`CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH`](/docs/en/env-vars) to the number of subagent layers you want below your main conversation, `2` or higher; see [nested subagents](/docs/en/sub-agents#let-subagents-spawn-their-own-subagents). From Claude Code v2.1.172 through v2.1.216, subagents could nest by default, up to five layers.
{/* min-version: 2.1.219 */}By default, subagents can spawn subagents of their own, up to three layers below the main conversation. {/* min-version: 2.1.217 */}To change the limit, set [`CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH`](/docs/en/env-vars) to the number of subagent layers you want below your main conversation, or `1` to turn nesting off; see [nested subagents](/docs/en/sub-agents#let-subagents-spawn-their-own-subagents).

Earlier versions used different defaults:

* **v2.1.172 through v2.1.216**: subagents could nest by default, up to five layers deep, and the limit couldn't be changed.
* **v2.1.217 through v2.1.218**: the limit defaulted to one, so a subagent couldn't spawn its own unless you raised it; {/* min-version: 2.1.219 */}v2.1.219 raised the default to three.

| `CLAUDE_CODE_MAX_OUTPUT_TOKENS` | Set the maximum number of output tokens for most requests. Defaults and caps vary by model; see [max output tokens](https://platform.claude.com/docs/en/about-claude/models/overview#latest-models-comparison). Increasing this value reduces the effective context window available before [auto-compaction](/docs/en/costs#reduce-token-usage) triggers |
| `CLAUDE_CODE_MAX_RETRIES` | Override the number of times to retry failed API requests (default: 10). {/* min-version: 2.1.186 */}Capped at 15 as of v2.1.186; {/* min-version: 2.1.199 */}as of v2.1.199, `CLAUDE_CODE_RETRY_WATCHDOG` raises the default and removes the cap. For unattended sessions that need to wait through longer outages, set `CLAUDE_CODE_RETRY_WATCHDOG` instead |
| `CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION` | {/* min-version: 2.1.212 */}Cap on the number of [subagents](/docs/en/sub-agents#session-subagent-limit) one session can spawn with the Agent tool (default: 200). When Claude reaches the cap, spawning another subagent fails with an error telling Claude to finish the remaining work directly. Accepts a positive whole number in plain digits with no upper bound; this variable doesn't take the scientific notation or digit-separator spellings. Anything else is ignored and the default applies, so the cap can be raised but not turned off. Requires Claude Code v2.1.212 or later |
| `CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH` | {/* min-version: 2.1.217 */}Number of [subagent layers](/docs/en/sub-agents#let-subagents-spawn-their-own-subagents) allowed below the main conversation (default: 1). At the default, subagents can't spawn their own subagents; set `2` or higher to allow it. Accepts a positive whole number in plain digits; anything else is ignored, so the limit can be raised but not turned off. Requires Claude Code v2.1.217 or later |
| `CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH` | {/* min-version: 2.1.217 */}Number of [subagent layers](/docs/en/sub-agents#let-subagents-spawn-their-own-subagents) allowed below the main conversation {/* min-version: 2.1.219 */}(default: 3). At the default, subagents can spawn their own subagents, and a subagent at the third layer can't spawn further; set `1` to turn nesting off. In v2.1.217 through v2.1.218, the default was 1, so a subagent couldn't spawn its own unless you raised the limit; v2.1.219 raised the default to 3. Accepts a positive whole number in plain digits; anything else is ignored, so the limit can be adjusted but not removed. Requires Claude Code v2.1.217 or later |
| `CLAUDE_CODE_MAX_TOOL_USE_CONCURRENCY` | Maximum number of read-only tools and subagents that can execute in parallel (default: 10). Higher values increase parallelism but consume more resources |
| `CLAUDE_CODE_MAX_TURNS` | Cap the number of agentic turns when no explicit limit is passed. Equivalent to passing [`--max-turns`](/docs/en/cli-reference#cli-flags), which takes precedence when both are set. A value that is not a positive integer is rejected at startup with an error rather than treated as no cap |
| `CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION` | {/* min-version: 2.1.212 */}Cap on the total number of [WebSearch](/docs/en/tools-reference#websearch-tool-behavior) calls one session can make (default: 200). When Claude reaches the cap, further WebSearch calls return a notice telling it to continue with the information it already gathered. Accepts a positive whole number with no upper bound. Anything else is ignored and the default applies, so the cap can be raised but not turned off. Requires Claude Code v2.1.212 or later |
