Supports custom subagents
description
The agent platform can load user-defined subagent definitions from disk
(parallel to a Skill's SKILL.md). The on-disk format is recorded on
`AgentPlatformImpl.subagentDefinitionFormat` (e.g. `claude-code-md` for
Claude Code's `.claude/agents/<name>.md` Markdown-with-YAML-frontmatter
format). Distinct from `capability:supports-subagent-dispatch` — a runtime
can dispatch built-in subagents without supporting custom definitions, and
a platform can declare custom-subagent loading even on top of a runtime
that uses a non-task-tool dispatch mechanism.
