+
+#### Sprint 7: Multi-Model Agent Support
+Configurable model selection for agents with inheritance chain.
+
+**Model Configuration:**
+- Agent-level `model` field in YAML frontmatter (opus|sonnet|haiku)
+- Plugin-level `defaultModel` in plugin.json
+- Inheritance: Agent → Plugin → System default (sonnet)
+
+**Recommended Model Assignments:**
+| Model | Use Case | Agents |
+|-------|----------|--------|
+| **Opus** | Complex reasoning, security analysis | planner, code-reviewer, security-reviewer, data-analysis |
+| **Sonnet** | Implementation, coordination | orchestrator, executor, layout-builder, data-ingestion |

+
+Agents can specify preferred Claude models for cost/performance optimization:
+
+| Model | Use For | Agents |
+|-------|---------|--------|
+| `opus` | Complex reasoning, security | planner, code-reviewer, security-reviewer |
+| `sonnet` | Implementation, coordination | orchestrator, executor, most agents |
+| `haiku` | Simple validation | component-check, agent-check |
+
+**Configuration:** Add `model: opus|sonnet|haiku` to agent frontmatter, or `defaultModel` to plugin.json.
+**Inheritance:** Agent → Plugin default → System default (sonnet)

+See `docs/MODEL-RECOMMENDATIONS.md` for detailed guidance.

+## Agent Model Configuration
+
+Agents can specify which Claude model to use for optimal cost/performance.
+
+### Model Options
+
+| Model | Use For | Cost |
+|-------|---------|------|
+| `opus` | Complex reasoning, security analysis | Highest |
+| `sonnet` | Implementation, coordination (default) | Medium |
+| `haiku` | Simple validation, quick checks | Lowest |
+
+### Configuration Levels
+
+**1. Agent-Level (highest priority)**
+
+Add to agent frontmatter in `agents/*.md`:
+
+```yaml
+---
+name: planner
+description: Sprint planning agent
+model: opus
+---
+```
+
+**2. Plugin-Level (fallback)**
+
+Add to `plugin.json`:
+
+```json
+{
+  "defaultModel": "sonnet"
+}
+```
+
+**3. System Default**
+
+If neither is specified, agents use `sonnet`.
+
+### Inheritance Chain
+
+```
+Agent model → Plugin defaultModel → System default (sonnet)
+```

+# Model Recommendations
+
+Guidelines for selecting Claude models (opus, sonnet, haiku) for plugin agents.
+
+---
+
+## Model Overview
+
+| Model | Best For | Cost | Speed |
+|-------|----------|------|-------|
+| **Opus** | Complex reasoning, architecture decisions, security analysis | Highest | Slower |
+| **Sonnet** | Implementation, coordination, standard tasks | Medium | Balanced |
+| **Haiku** | Simple validation, quick checks, status queries | Lowest | Fastest |
+
+---
+
+## Task-Type Recommendations
+
+| Task Type | Model | Rationale |
+|-----------|-------|-----------|
+| Architecture decisions | Opus | Requires deep reasoning, trade-off analysis |
+| Security analysis | Opus | Critical thinking, vulnerability pattern recognition |
+| Code review (quality) | Opus | Thorough analysis, edge case detection |
+| Sprint planning | Opus | Strategic thinking, dependency analysis |
+| Complex data analysis | Opus | Multi-step reasoning, insight generation |
+| Code implementation | Sonnet | Fast, capable code generation |
+| Coordination/dispatch | Sonnet | Task management, status tracking |
+| Data transformation | Sonnet | ETL operations, query building |
+| Documentation | Sonnet | Clear writing, structure |
+| Simple validation | Haiku | Fast prop checks, schema validation |
+| Status checks | Haiku | Quick queries, cost-effective |
+| Quick verification | Haiku | Simple pass/fail checks |
+
+---
+
+## Agent Model Assignments
+
+### projman (Sprint Management)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `planner` | opus | Architecture decisions, issue structuring |
+| `orchestrator` | sonnet | Coordination, parallel execution |
+| `executor` | sonnet | Code implementation |
+| `code-reviewer` | opus | Quality review, security analysis |
+
+### pr-review (PR Analysis)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `coordinator` | sonnet | Task dispatch, result aggregation |
+| `security-reviewer` | opus | Security vulnerability detection |
+| `performance-analyst` | sonnet | Pattern recognition |
+| `maintainability-auditor` | sonnet | Code quality checks |
+| `test-validator` | sonnet | Test coverage analysis |
+
+### code-sentinel (Security & Refactoring)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `security-reviewer` | opus | Security scanning |
+| `refactor-advisor` | sonnet | Refactoring suggestions |
+
+### data-platform (Data Engineering)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `data-analysis` | opus | Complex data insights |
+| `data-ingestion` | sonnet | ETL operations |
+
+### viz-platform (Visualization)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `component-check` | haiku | Simple prop validation |
+| `layout-builder` | sonnet | UI construction |
+| `theme-setup` | sonnet | Design configuration |
+
+### contract-validator (Compatibility)
+
+| Agent | Model | Rationale |
+|-------|-------|-----------|
+| `full-validation` | sonnet | Contract checking |
+| `agent-check` | haiku | Quick verification |
+
+---
+
+## Configuration Schema
+
+### Agent-Level (Frontmatter)
+
+Add `model` field to agent YAML frontmatter:
+
+```yaml
+---
+name: planner
+description: Sprint planning agent
+model: opus
+---
+```
+
+**Valid values:** `opus`, `sonnet`, `haiku`
+
+### Plugin-Level (plugin.json)
+
+Add `defaultModel` for plugin-wide fallback:
+
+```json
+{
+  "name": "projman",
+  "version": "3.4.0",
+  "defaultModel": "sonnet"
+}
+```
+
+---
+
+## Inheritance Chain
+
+Model selection follows this precedence:
+
+```
+1. Agent model field (highest priority)
+      ↓ if not specified
+2. Plugin defaultModel (plugin.json)
+      ↓ if not specified
+3. System default: sonnet
+```
+
+**Example:**
+- Agent has `model: opus` → Uses opus
+- Agent has no model, plugin has `defaultModel: sonnet` → Uses sonnet
+- Neither specified → Uses sonnet (system default)
+
+---
+
+## Cost Optimization Tips
+
+1. **Default to Sonnet** - Good balance for most tasks
+2. **Reserve Opus** for critical decisions (security, architecture)
+3. **Use Haiku** for validation and quick checks
+4. **Batch simple tasks** - Use haiku for parallel validation
+
