What's Wrong?

When using agent teams (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1), typing /compact in an in-process teammate's chat window does not trigger compaction. Instead, the agent interprets it as a regular text message and writes a summary as conversational output — no actual compaction occurs.

Auto-compaction (at the configured threshold) works correctly in teammates. Only manual /compact is affected.

Expected Behavior

/compact should trigger actual context compaction in teammate sessions, same as it does in the main orchestrator session. This is important for managing token costs in long-running team sessions with 1M context windows.

Steps to Reproduce

1. Start Claude Code with CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
2. Create a team and spawn a teammate
3. Focus on the teammate's chat
4. Type /compact
5. Observe: the agent writes a summary as text output instead of compacting

Analysis (from reading the bundled source)

Looking at cli.js in the npm package, it appears that in-process agent sessions are initialized with commands: [] (empty array), which excludes all slash commands including /compact.

Auto-compaction works because it runs in the main generation loop independently of the commands array. Manual /compact doesn't work because the command isn't registered in the agent's session.

The compact command itself has no agent-specific gate — its only check is !DISABLE_COMPACT. The limitation comes from the empty commands array passed during agent session setup.

Environment

• Claude Code v2.1.76 (native installer, Windows)
• CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
• In-process teammate mode (not tmux)
