-### Added
+### Removed
+
+#### Multi-Model Agent Support (REVERTED)
+
+**Reason:** Claude Code does not support `defaultModel` in plugin.json or `model` in agent frontmatter. The schema validation rejects these as "Unrecognized key".
+
+**Removed:**
+- `defaultModel` field from all plugin.json files (6 plugins)
+- `model` field references from agent frontmatter
+- `docs/MODEL-RECOMMENDATIONS.md` - Deleted entirely
+- Model configuration sections from `docs/CONFIGURATION.md` and `CLAUDE.md`
+
+**Lesson:** Do not implement features without verifying they are supported by Claude Code's plugin schema.

+## [5.4.0] - 2026-01-28 [REVERTED]
+
+### Added (NOW REMOVED - See 5.4.1)
 
 #### Sprint 7: Multi-Model Agent Support
-Configurable model selection for agents with inheritance chain.
+~~Configurable model selection for agents with inheritance chain.~~
 
-**Model Configuration:**
+**This feature was reverted in 5.4.1 - Claude Code does not support these fields.**
-- Agent-level `model` field in YAML frontmatter (opus|sonnet|haiku)
-- Plugin-level `defaultModel` in plugin.json
-- Inheritance: Agent → Plugin → System default (sonnet)

-### Agent Model Configuration
-
-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 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 |

-
-### data-platform (Data Engineering)
-
-| Agent | Model | Rationale |
-|-------|-------|-----------|
-| `data-analysis` | opus | Complex data insights |
-| `data-ingestion` | sonnet | ETL operations |
-
-### viz-platform (Visualization)
-
-| Agent | Model | Rationale |
-|-------|-------|-----------|

-
----
-
-## 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
