System Comparisons

This is a factual operational comparison, not a leaderboard.

It compares scoped interfaces by architectural role and keeps finding, delivery mechanism, evidence/outcome, review date, material configuration, and limitations independently visible.

Unknown is not unsupported. Not applicable is not a failure. A failed live test is not partial support. A shared protocol is not proof of tested interoperability.

For definitions and correction rules, see the comparison methodology.

Evidence Claude Code 2.1.275 release notes · Release note	AvailableNativePrimary docs · Sep 25, 2026 Evidence & scope Prerequisites Subagents are available natively; agent teams are experimental and require explicit enablement. Limitations Agent teams are experimental; this finding does not claim identical semantics between subagents and agent teams. Evidence Claude Code subagents and agent teams · Primary docs	AvailableNativePrimary docs · Sep 25, 2026 Evidence & scope Limitations This finding covers Claude Code-native delegation to subagents; it does not establish cross-vendor handoff or A2A interoperability. Evidence Claude Code subagent delegation · Primary docs	AvailableConfigured nativePrimary docs · Sep 25, 2026 Evidence & scope Prerequisites Use permission rules and/or PreToolUse hooks rather than bypassPermissions when a protected gate is required.

Evidence Claude Code permissions and PreToolUse hooks · Primary docs	Partial / conditionalConfigured nativePrimary docs · Sep 25, 2026 Evidence & scope Limitations Session/hook context can identify the session and decision path, but the reviewed CLI docs do not establish durable named-human Principal attribution for every approval decision.

Evidence Claude Code OpenTelemetry and usage monitoring · Primary docs	AvailableConfigured nativePrimary docs · Sep 25, 2026 Evidence & scope Prerequisites Configure one of the documented hard bounds such as tool/subagent concurrency or output-token limits.

Directed integration observations

These records answer a narrower question than the feature grid: which specific source and target interfaces have evidence of a particular relationship. An adapter or shared protocol does not automatically establish every lifecycle or governance behavior.
