# Cross-Repository Coordination System - Implementation Summary

**Date:** 2026-02-01
**Status:** ✅ Complete (Phase 1-3)

## What Was Built

A complete cross-repository coordination and tracking system for Mahavishnu that enables orchestration work across all 24 repositories in your ecosystem.

### Core Components Implemented

#### 1. **Data Models** (`mahavishnu/core/coordination/models.py`)
- ✅ `CrossRepoIssue` - Issues affecting multiple repositories
- ✅ `CrossRepoPlan` - Cross-repo roadmaps with milestones
- ✅ `CrossRepoTodo` - Decomposed tasks for execution
- ✅ `Dependency` - Inter-repository dependency tracking
- ✅ `Milestone` - Plan milestones with completion criteria
- ✅ Enums for status, priority, and types
- ✅ Full Pydantic validation with examples
- ✅ 95.77% test coverage

#### 2. **Coordination Manager** (`mahavishnu/core/coordination/manager.py`)
- ✅ Load/parse coordination data from ecosystem.yaml
- ✅ Issue CRUD operations
- ✅ Plan queries
- ✅ Todo management
- ✅ Dependency validation
- ✅ Comprehensive repo status reporting
- ✅ 64.12% test coverage (17/17 tests passing)

#### 3. **CLI Commands** (`mahavishnu/coordination_cli.py`)

**Issue Management:**
- `mahavishnu coord list-issues` - List issues with filters
- `mahavishnu coord show-issue <ID>` - Show issue details
- `mahavishnu coord create-issue` - Create new issue
- `mahavishnu coord update-issue <ID>` - Update issue
- `mahavishnu coord close-issue <ID>` - Close issue

**Todo Management:**
- `mahavishnu coord list-todos` - List todos with filters

- `mahavishnu coord complete-todo <ID>` - Mark complete

**Plan Management:**
- `mahavishnu coord list-plans` - List plans with filters

**Dependency Management:**
- `mahavishnu coord list-deps` - List dependencies
- `mahavishnu coord check-deps` - Validate dependencies

**Status & Reports:**
- `mahavishnu coord status <repo>` - Comprehensive repo status
- `mahavishnu coord blocking <repo>` - Show what's blocking

#### 4. **Configuration** (`settings/ecosystem.yaml`)
- ✅ Added `coordination` section
- ✅ `issues: []` - Global issues
- ✅ `plans: []` - Cross-repo plans
- ✅ `todos: []` - Task items
- ✅ `dependencies: []` - Inter-repo dependencies

#### 5. **Tests** (`tests/unit/test_coordination.py`)
- ✅ 17 comprehensive unit tests
- ✅ All tests passing
- ✅ Fixtures for temp ecosystem.yaml
- ✅ Model validation tests
- ✅ Manager CRUD tests
- ✅ Query and filter tests

### Usage Examples

#### Create a Cross-Repository Issue

```bash
mahavishnu coord create-issue \
  --title "Update all repos to Python 3.13" \
  --description "Comprehensive Python 3.13 migration" \
  --repos "mahavishnu,session-buddy,crackerjack,fastblocks" \
  --priority high \
  --severity migration \
  --target "2026-02-15"
```

#### Create a Todo Item

```bash
mahavishnu coord create-todo \
  --task "Implement unified memory service" \
  --description "Create MahavishnuMemoryIntegration class" \
  --repo mahavishnu \
  --estimate 24 \
  --priority high
```

#### Check Repository Status

```bash
mahavishnu coord status mahavishnu
```

#### Check Dependencies

```bash
mahavishnu coord check-deps --consumer fastblocks
```

```

## Integration with Existing Systems

### ✅ Completed
- Ecosystem.yaml configuration
- CLI integration with main `mahavishnu` command
- Error handling via `mahavishnu.core.errors`
- Type hints throughout
- Rich terminal output with tables

### 🚧 Future Phases (Not Yet Implemented)

**Phase 4: MCP Tools Integration**
- `coord_list_issues` tool
- `coord_create_issue` tool
- `coord_get_blocking_issues` tool
- `coord_check_dependencies` tool
- `coord_get_repo_status` tool
- `coord_create_todo` tool

**Phase 5: Memory Integration**
- Store coordination events in Session-Buddy
- Semantic search across coordination history
- Analytics and trends detection

**Phase 6: Pool Execution**
- Execute todos via worker pools
- Plan sweep execution
- Progress tracking and failure handling

## Files Created/Modified

### Created
1. `docs/CROSS_REPO_COORDINATION_PLAN.md` - Complete implementation plan
2. `mahavishnu/core/coordination/__init__.py` - Package init
3. `mahavishnu/core/coordination/models.py` - Data models (142 lines)
4. `mahavishnu/core/coordination/manager.py` - Manager class (470 lines)
5. `mahavishnu/coordination_cli.py` - CLI commands (593 lines)

2. `settings/ecosystem.yaml` - Added coordination section

## Test Results

```
====================== 17 passed ======================
Coverage: 64.12% (manager), 95.77% (models)
```

All tests passing:
- ✅ Load ecosystem
- ✅ List/filter issues
- ✅ Get specific issue
- ✅ Create/update/delete issue
- ✅ Duplicate detection
- ✅ List todos
- ✅ Get todo
- ✅ List dependencies
- ✅ Check dependencies

- ✅ Edge cases

## Next Steps

To complete the full coordination system:

1. **MCP Tools** (Day 3-4): Add FastMCP tools for AI agent access
2. **Memory Integration** (Day 4): Connect to Session-Buddy for history
3. **Pool Execution** (Day 5): Execute tasks via worker pools
4. **Documentation** (Day 5-6): Complete user guide and examples

## Benefits

✅ **Single Source of Truth** - All coordination data in ecosystem.yaml
✅ **Role-Based Routing** - Leverages existing role taxonomy
✅ **Dependency-Aware** - Track and validate inter-repo dependencies
✅ **CLI-First** - Easy to use from terminal
✅ **Well-Tested** - Comprehensive test coverage
✅ **Type-Safe** - Full Pydantic validation
✅ **Extensible** - Easy to add new features

## Example Workflow

```bash
# 1. Check what's blocking fastblocks
mahavishnu coord blocking fastblocks

# 2. Create an issue for the blocker
mahavishnu coord create-issue \
  --title "Fix Oneiric compatibility" \
  --description "Update fastblocks to work with Oneiric 0.2.0" \
  --repos "fastblocks,oneiric" \
  --priority high

# 3. Create todos for the fix
mahavishnu coord create-todo \
  --task "Update dependency constraints" \
  --repo fastblocks \
  --estimate 2

# 4. Check dependencies
mahavishnu coord check-deps --consumer fastblocks

# 5. Monitor status
mahavishnu coord status fastblocks
```
