+# Sprint 4: Commands Implementation
+
+Implementation of 16 new user-facing commands across 8 plugins.
+
+## Scope
+
+| Plugin | Items | Description |
+|--------|-------|-------------|
+| projman | 1 | Dynamic sprint diagram |
+| pr-review | 2 | Confidence threshold, pr-diff command |
+| data-platform | 3 | data-quality, lineage-viz, dbt-test |
+| viz-platform | 3 | chart-export, color blind validation, responsive breakpoints |
+| contract-validator | 1 | dependency-graph command |
+| doc-guardian | 3 | changelog-gen, doc coverage, stale doc warnings |
+| claude-config-maintainer | 2 | config-diff, linting best practices |
+| cmdb-assistant | 3 | cmdb-topology, change audit, IP conflict detection |
+
+## Architecture Decisions
+
+### Command Implementation Pattern
+
+All commands follow the standard plugin command structure:
+```
+plugins/{name}/commands/{command}.md
+```
+
+Commands that generate Mermaid diagrams should output raw Mermaid syntax that can be rendered by compatible tools.
+
+### Task Sizing
+
+Per Sprint 3 lessons, all tasks sized S or M:
+- **S (Simple):** Single command file, 2-4 checklist items
+- **M (Medium):** Command + supporting changes, 4-6 checklist items
+
+### Dependencies
+
+- Mermaid-generating commands (sprint-diagram, lineage-viz, dependency-graph, cmdb-topology) share similar output patterns
+- No cross-plugin dependencies within this sprint
+
+## Issues
+
+*To be populated during planning*
+
+## Lessons Applied
+
+From Sprint 3:
+- Keep tasks scoped to S/M size (avoid 400+ tool call runaway)
+- Pre-grant agent permissions before dispatch
+- Use structured progress comments for visibility
