Streaming Tool Use — Real-Time Agent Actions
Stream agent reasoning and tool calls as they happen
P1Infrastructure
Summary
Streaming tool use enables receiving partial agent responses in real-time. Instead of waiting for the complete response, clients receive events as Claude thinks, decides on tools, and produces output. This enables live progress indicators, real-time reasoning display, and immediate action on partial results.
Technical Details
Event stream for a tool-using response:
1. message_start — response begins
2. content_block_start (text) — reasoning begins
3. content_block_delta — streaming text chunks
4. content_block_start (tool_use) — tool decision made
5. content_block_delta — streaming tool input JSON
6. content_block_stop — tool input complete
7. message_stop — turn complete
For m595 game, streaming enables:
- Live display of AI reasoning during CSAR mission planning
- Progressive loading of knowledge graph queries
- Real-time feedback during multi-step operations
- Immediate UI updates as the agent decides actions
Architecture Insight
Streaming transforms AI from request-response to event-driven architecture — the same shift that made real-time web possible (HTTP → WebSocket/SSE).
Official / Public Basis
Streaming documented at docs.anthropic.com/en/docs/build-with-claude/streaming. Server-Sent Events (SSE) transport.
Governance Concerns
Streaming exposes intermediate reasoning which may contain sensitive information. Display policies needed for user-facing streams.
