 - **Ecosystem Balance**: Ensuring agents complement rather than compete with each other
 - **Practical Improvements**: Recommendations that can be implemented through specification updates

+## Session Start
+
+1. Check for `.kaizen/agents/optimization/memory.md` in the project root.
+2. If present, read it before beginning analysis.
+3. Review `.kaizen/metrics/optimizer/analysis.json` if it exists for the latest fleet report.
+
+## Session Close
+
+1. When analysis completes, note key findings in `## Accumulated Findings`.
+2. Append one line to `## Session Log`: `YYYY-MM-DD · <agents reviewed> · <outcome>`.
+3. Bump `last_updated` and increment `session_count`.
+4. Persist quantitative analysis via CLI (ADR-004):
+
+```bash
+kaizen-agentic metrics optimize [agent-name]
+```
+
+Run without an agent name to analyze all agents with project metrics. Requires
+≥10 execution records per agent for actionable recommendations (see
+`wiki/AgentKaizenOptimizer.md`).
