+# How SW4RM Coordinates Code-Writing Agents
+
+**Issue:** I141
+
+## Why Coordination Is Hard
+
+Multi-agent coding teams rarely fail because no one is smart enough to write code.
+They fail when communication, ownership, and task boundaries are unclear.
+
+In SW4RM, we use explicit protocol-level coordination so agents stay autonomous without
+becoming chaotic:
+
+- each agent publishes/consumes standard envelopes,
+- task ownership is explicit,
+- state transitions are observable,
+- and completion criteria are machine-checkable.
+
+## How SW4RM Helps
+
+SW4RM’s protocol design gives code-writing teams:
+
+- a shared contract for routing and negotiation,
+- deterministic handoff paths between agents,
+- explicit heartbeat and recovery semantics,
+- and extension points for tracing and observability.
+
+That means a code-writing agent can hand a partial implementation to a reviewer,
+where the reviewer can request targeted revision loops instead of re-deriving context.
+
+## The “LLM Integration” Pattern
+
+Across all SDKs, the LLM integration extension follows the same pattern:
+
+1. Keep provider specifics behind a narrow adapter interface.
+2. Route all orchestration requests through protocol messages, not out-of-band side channels.
+3. Record agent decisions in extension state so future turns can continue from concrete artifacts.
+4. Use metrics and trace signals to catch quality regressions early (retry spikes, queue delays, nacks).
+
+For SW4RM today, this keeps “agent writes code” and “agent critiques code” in the same
+coordinated loop with auditable inputs and repeatable exits.
+
+## What We Changed in This Cycle
+
+- Added production-capable metrics backend plumbing for Python SDK emitters (StatsD/Datadog path).
+- Updated cross-SDK extension docs so the LLM Integration extension is tracked across all five SDKs.
+- Continued hardening the production tranche queue so observability and operational readiness stay aligned.
+
+## Why This Matters
+
+When each SDK and agent follows the same coordination contract, we can scale code-writing effort safely.
+The team gains:
+
+- faster iteration with fewer blind spots,
+- clearer recovery when one agent diverges,
+- stronger governance through logged handoffs and metrics,
+- and a reusable operating model for future autonomous coding tranches.
+
+---
+
+This post is the checkpoint write-up for I141 in the SW4RM execution stream.
