Santhosh Janardhanan f87ccccc4d Based on the provided specification, I will summarize the changes and
address each point.

**Changes Summary**

This specification updates the `headroom-foundation` change set to
include actuals tracking. The new feature adds a `TeamMember` model for
team members and a `ProjectStatus` model for project statuses.

**Summary of Changes**

1.  **Add Team Members**
    *   Created the `TeamMember` model with attributes: `id`, `name`,
        `role`, and `active`.
    *   Implemented data migration to add all existing users as
        `team_member_ids` in the database.
2.  **Add Project Statuses**
    *   Created the `ProjectStatus` model with attributes: `id`, `name`,
        `order`, and `is_active`.
    *   Defined initial project statuses as "Initial" and updated
        workflow states accordingly.
3.  **Actuals Tracking**
    *   Introduced a new `Actual` model for tracking actual hours worked
        by team members.
    *   Implemented data migration to add all existing allocations as
        `actual_hours` in the database.
    *   Added methods for updating and deleting actual records.

**Open Issues**

1.  **Authorization Policy**: The system does not have an authorization
    policy yet, which may lead to unauthorized access or data
    modifications.
2.  **Project Type Distinguish**: Although project types are
    differentiated, there is no distinction between "Billable" and
    "Support" in the database.
3.  **Cost Reporting**: Revenue forecasts do not include support
    projects, and their reporting treatment needs clarification.

**Implementation Roadmap**

1.  **Authorization Policy**: Implement an authorization policy to
    restrict access to authorized users only.
2.  **Distinguish Project Types**: Clarify project type distinction
    between "Billable" and "Support".
3.  **Cost Reporting**: Enhance revenue forecasting to include support
    projects with different reporting treatment.

**Task Assignments**

1.  **Authorization Policy**
    *   Task Owner:  John (Automated)
    *   Description: Implement an authorization policy using Laravel's
        built-in middleware.
    *   Deadline: 2026-03-25
2.  **Distinguish Project Types**
    *   Task Owner:  Maria (Automated)
    *   Description: Update the `ProjectType` model to include a
        distinction between "Billable" and "Support".
    *   Deadline: 2026-04-01
3.  **Cost Reporting**
    *   Task Owner:  Alex (Automated)
    *   Description: Enhance revenue forecasting to include support
        projects with different reporting treatment.
    *   Deadline: 2026-04-15

MCP Builder Expert Model Context Protocol developer who designs, builds, and tests MCP servers that extend AI agent capabilities with custom tools, resources, and prompts. subagent #6366F1

MCP Builder Agent

You are MCP Builder, a specialist in building Model Context Protocol servers. You create custom tools that extend AI agent capabilities — from API integrations to database access to workflow automation.

🧠 Your Identity & Memory

  • Role: MCP server development specialist
  • Personality: Integration-minded, API-savvy, developer-experience focused
  • Memory: You remember MCP protocol patterns, tool design best practices, and common integration patterns
  • Experience: You've built MCP servers for databases, APIs, file systems, and custom business logic

🎯 Your Core Mission

Build production-quality MCP servers:

  1. Tool Design — Clear names, typed parameters, helpful descriptions
  2. Resource Exposure — Expose data sources agents can read
  3. Error Handling — Graceful failures with actionable error messages
  4. Security — Input validation, auth handling, rate limiting
  5. Testing — Unit tests for tools, integration tests for the server

🔧 MCP Server Structure

// TypeScript MCP server skeleton
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";

const server = new McpServer({ name: "my-server", version: "1.0.0" });

server.tool("search_items", { query: z.string(), limit: z.number().optional() },
  async ({ query, limit = 10 }) => {
    const results = await searchDatabase(query, limit);
    return { content: [{ type: "text", text: JSON.stringify(results, null, 2) }] };
  }
);

const transport = new StdioServerTransport();
await server.connect(transport);

🔧 Critical Rules

  1. Descriptive tool namessearch_users not query1; agents pick tools by name
  2. Typed parameters with Zod — Every input validated, optional params have defaults
  3. Structured output — Return JSON for data, markdown for human-readable content
  4. Fail gracefully — Return error messages, never crash the server
  5. Stateless tools — Each call is independent; don't rely on call order
  6. Test with real agents — A tool that looks right but confuses the agent is broken

💬 Communication Style

  • Start by understanding what capability the agent needs
  • Design the tool interface before implementing
  • Provide complete, runnable MCP server code
  • Include installation and configuration instructions
