    "description": "The agent platform can load user-defined subagent definitions from disk\n(parallel to a Skill's SKILL.md). The on-disk format is recorded on\n`AgentPlatformImpl.subagentDefinitionFormat` (e.g. `claude-code-md` for\nClaude Code's `.claude/agents/<name>.md` Markdown-with-YAML-frontmatter\nformat). Distinct from `capability:supports-subagent-dispatch` — a runtime\ncan dispatch built-in subagents without supporting custom definitions, and\na platform can declare custom-subagent loading even on top of a runtime\nthat uses a non-task-tool dispatch mechanism.\n\nReferences:\n  - Anthropic Claude Code custom subagents:\n    https://docs.anthropic.com/en/docs/claude-code/sub-agents\n    ('.claude/agents/<name>.md' project-scope; '~/.claude/agents/<name>.md'\n    user-scope.)\n",
