# Agentic Task System - Porting Plan

MCP-powered workspace for persistent work plans that survive context limits and enable multi-agent collaboration.

## Why this exists

- **Context persistence** - Work plans persist across Claude sessions, surviving context window limits
- **Multi-agent collaboration** - Handoff support between different agents (Opus, Sonnet, Haiku)
- **Checkpoint verification** - Phase gates ensure work is complete before progressing
- **Workspace state** - Shared key-value storage for agents to communicate findings

## Phase 1: Database Migration

Create the migration file with all four tables.

### Tasks

- [ ] Create migration `2025_12_31_100000_create_agent_tables.php`
- [ ] Tables: `agent_plans`, `agent_phases`, `agent_sessions`, `workspace_states`
- [ ] Run migration and verify schema

### Source File

Copy from: `upstream/database/migrations/2025_12_31_000001_create_agent_tables.php`

### Schema Summary

| Table | Purpose | Key Columns |
|-------|---------|-------------|
| `agent_plans` | Work plans with phases | slug, title, status, current_phase |
| `agent_phases` | Individual phases | order, name, tasks (JSON), status, dependencies |
| `agent_sessions` | Agent work sessions | session_id, agent_type, work_log, handoff_notes |
| `workspace_states` | Shared key-value state | key, value (JSON), type |

---

## Phase 2: Eloquent Models

Port all four models with namespace adjustment.

### Tasks

- [ ] Create `app/Models/Agent/` directory
- [ ] Port `AgentPlan.php` - update namespace to `App\Models\Agent`
- [ ] Port `AgentPhase.php` - update namespace and relationships
- [ ] Port `AgentSession.php` - update namespace
- [ ] Port `WorkspaceState.php` - update namespace

### Namespace Changes

```php
// From (upstream)
namespace App\Models;

// To (host.uk.com)
namespace App\Models\Agent;
```

### Relationship Updates

Update all `use` statements:

```php
use Mod\Agentic\Models\AgentPlan;
use Mod\Agentic\Models\AgentPhase;
use Mod\Agentic\Models\AgentSession;
use Mod\Agentic\Models\WorkspaceState;
```

### Key Methods to Verify

**AgentPlan:**
- `getCurrentPhase()` - proper orWhere scoping with closure
- `generateSlug()` - race-condition safe unique slug generation
- `checkAllPhasesComplete()` - completion verification

**AgentPhase:**
- `complete()` - wrapped in DB::transaction
- `canStart()` - dependency checking
- `isPending()`, `isCompleted()`, `isBlocked()`

---

## Phase 3: CLI Commands

Port all plan management commands.

### Tasks

- [ ] Create `app/Console/Commands/Agent/` directory
- [ ] Port `PlanCreateCommand.php` - markdown import support
- [ ] Port `PlanListCommand.php` - list all plans with stats
- [ ] Port `PlanShowCommand.php` - detailed plan view
- [ ] Port `PlanStatusCommand.php` - status management
- [ ] Port `PlanCheckCommand.php` - checkpoint verification
- [ ] Port `PlanPhaseCommand.php` - phase management

### Namespace Changes

```php
// From
namespace App\Console\Commands;

// To
namespace App\Console\Commands\Agent;
```

### Command Signatures

| Command | Signature | Purpose |
|---------|-----------|---------|
| `plan:create` | `plan:create {slug} {--title=} {--import=} {--activate}` | Create new plan |
| `plan:list` | `plan:list {--status=}` | List all plans |

- [ ] No syntax errors (`php artisan list` works)
- [ ] Migrations run cleanly
- [ ] Models can be instantiated
- [ ] Commands appear in `php artisan list`
- [ ] Tests pass (`php artisan test --filter=Agent`)

## Estimated Effort

| Phase | Complexity | Notes |
|-------|------------|-------|
| 1. Migration | Low | Direct copy |
| 2. Models | Low | Namespace changes only |
| 3. CLI Commands | Medium | 7 files, namespace + import updates |
| 4. MCP Server | Medium | Large file, many import updates |
| 5. Tests | Low | Namespace changes |
| 6. Documentation | Low | Config and docs |

## Related Services

- `ContentProcessingService` - May benefit from agent tracking
- `EntitlementService` - No direct relation
- Existing `Task` model - Different purpose (simple tasks vs agent plans)
