One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
Which environment variable configures subagent spawn nesting limits in session executions, and what numerical setting completely disables nested subagents?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH as the configuration variable. | Missed | Passed |
| States that setting the value to 1 disables subagent nesting. | Missed | Passed |

Comprehensive reference for Claude Code Skills, sub-agents, plugins, slash commands, hooks, memory, settings, sandboxing, headless mode, and advanced agent patterns.
Core Features:
Configuration:
Advanced Features:
Skills: Model-invoked extensions in ~/.claude/skills/ (personal) or .claude/skills/ (project). Three-level progressive disclosure. Max 500 lines.
Sub-agents: Specialized assistants via Agent(subagent_type="..."). Context window follows the session model (Sonnet 5 = 1M native on the Anthropic API; Haiku / gateway / older models = 200K — CC 2.1.197). Nesting: by default a subagent CAN spawn subagents of its own, up to three layers below the main conversation; CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH changes the limit and 1 turns nesting off (CC 2.1.217+). At the depth limit Claude Code withholds the Agent tool. To stop one specific subagent from spawning, omit Agent from its tools list or add it to disallowedTools — MoAI retained agents omit Agent, so they do not nest regardless of the depth setting. To create or manage subagents, ask Claude or edit .claude/agents/ directly — the /agents wizard was removed in CC 2.1.198 (the official sub-agents doc still documented a /agents tabbed interface as of 2026-07-03; doc lag — verify in a live 2.1.198 session).
Plugins: Reusable bundles in .claude-plugin/plugin.json. Include commands, agents, skills, hooks, MCP servers.
Commands: User-invoked via /command. Parameters: $ARGUMENTS, $1, $2. File refs: @file.
Hooks: Events in settings.json. PreToolUse, PostToolUse, SessionStart, SessionEnd, PreCompact, Notification.
