**Source:** MSP-MODE-SPEC.md
**Section:** MSP Work Tracking Tables
**Date:** 2026-01-15
## Overview
MSP work tracking tables for detailed session work items, task management, and work details tracking. These tables capture granular information about work performed during MSP sessions.
---
## MSP Work Tracking Tables
### `work_items`
Individual tasks/actions within sessions (granular tracking).
```sql
CREATE TABLE work_items (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
session_id UUID NOT NULL REFERENCES sessions(id) ON DELETE CASCADE,
category VARCHAR(50) NOT NULL CHECK(category IN (
'infrastructure', 'troubleshooting', 'configuration',
'development', 'maintenance', 'security', 'documentation'
)),
title VARCHAR(500) NOT NULL,
description TEXT NOT NULL,
status VARCHAR(50) DEFAULT 'completed' CHECK(status IN (
'completed', 'in_progress', 'blocked', 'pending', 'deferred'
)),
priority VARCHAR(20) CHECK(priority IN ('critical', 'high', 'medium', 'low')),
is_billable BOOLEAN DEFAULT false,
estimated_minutes INTEGER,
actual_minutes INTEGER,
affected_systems TEXT, -- JSON array: ["jupiter", "172.16.3.20"]
technologies_used TEXT, -- JSON array: ["docker", "mariadb"]

created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
completed_at TIMESTAMP,
INDEX idx_work_items_session (session_id),
INDEX idx_work_items_category (category),
INDEX idx_work_items_status (status)
);
```
**Categories distribution (from analysis):**
- Infrastructure: 30%
- Troubleshooting: 25%
- Configuration: 15%
- Development: 15%
- Maintenance: 10%
- Security: 5%

## Relationships
- `sessions``work_items` (one-to-many): Each session contains multiple work items
- `work_items``file_changes` (one-to-many): Track files modified in each work item
- `work_items``commands_run` (one-to-many): Commands executed for each work item
- `work_items``infrastructure_changes` (one-to-many): Infrastructure changes made
- `work_items``problem_solutions` (one-to-many): Problems solved in work item
- `work_items``deployments` (one-to-many): Deployments performed
- `work_items``database_changes` (one-to-many): Database modifications
- `work_items``tags` (many-to-many via work_item_tags)
---
## Work Item Categorization
### Auto-Categorization Logic
As work progresses, agents analyze conversation and actions to categorize work:
**Keyword Triggers:**
- **infrastructure:** "ssh", "docker restart", "service", "server", "network"
- **troubleshooting:** "error", "not working", "broken", "failed", "issue"
- **configuration:** "configure", "setup", "change settings", "modify"
- **development:** "build", "code", "implement", "create", "develop"
- **maintenance:** "cleanup", "optimize", "backup", "update", "patch"
- **security:** "malware", "breach", "unauthorized", "vulnerability", "firewall"
### Information-Dense Data Capture
Work items use concise, structured descriptions:
**Format:**
```
Problem: [what was wrong]
Cause: [root cause if identified]
Fix: [solution applied]
Verify: [how confirmed]
```
**Example:**
```
Problem: ERR_SSL_PROTOCOL_ERROR on git.azcomputerguru.com
Cause: Certificate expired 2026-01-10
Fix: certbot renew && systemctl restart apache2
Verify: curl test successful, browser loads site
```
---
## Billability Tracking
### Auto-flag Billable Work
- Client work (non-internal) → `is_billable = true` by default
- Internal infrastructure → `is_billable = false`
- User can override with command: `/billable false`
### Time Allocation
- Track time per work_item (start when created, end when completed)
- `actual_minutes` calculated from timestamps
- Aggregate to session total: `billable_hours` in sessions table
