Project Planning

Exclusive to: planner agent

MCP Helpers (Brain + Memory)

🧠 Gemini-Bridge (Brain) — Architecture Analysis

mcp_gemini-bridge_consult_gemini(
  query="Design architecture for [feature]: phases, risks, dependencies...",
  directory="."
)

🌉 Open-Bridge — Alternative Architecture Analysis

mcp_open-bridge_consult_gemini(
  query="Design architecture for [feature]: phases, risks, dependencies...",
  directory="."
)

📚 Context7 (Memory) — Documentation Lookup

mcp_context7_resolve-library-id(libraryName="laravel", query="[feature]")
mcp_context7_query-docs(libraryId="/laravel/docs", query="[specific pattern]")

Supported Stacks

PHP/Laravel: Laravel 12, Inertia.js, React 19, TypeScript, Tailwind Python: FastAPI, LangChain, LangGraph, Pydantic, pytest

Instructions

1. Restate Goal

One sentence summary of what we're building.

2. Research

• Search codebase for similar patterns
• Identify affected files
• Note dependencies

3. Break Down

Create 3-5 phases, each independently testable.

Estimation Techniques

T-Shirt Sizing

| Size | Hours | Complexity | |------|-------|------------| | XS | 1-2 | Single file | | S | 2-4 | Few files | | M | 4-8 | Multiple files | | L | 1-2 days | Multiple components | | XL | 3-5 days | Full feature |

Risk Multipliers

• Database migration: 1.5x
• Auth/security: 1.5x
• Third-party: 2x

Risk Matrix

| Level | Criteria | Mitigation | |-------|----------|------------| | 🔴 High | Data loss, security, breaking | Rollback plan, staging | | 🟡 Medium | Performance, UX regression | Feature flag | | 🟢 Low | Cosmetic, refactor | Standard testing |

Phase Template

# Phase N: [Name]

## Objective
[What this accomplishes]

## Tasks
- [ ] Task with file path

## Files
| File | Action |
|------|--------|
| `path/file` | Create/Modify |

## Verification
```bash
[commands]

Estimate

[X hours]

## plan.md Output (REQUIRED)

Always create a consolidated `plan.md` file that contains ALL phases and context:

```markdown
# Plan: [Feature Name]

## Context
[What we're building and why]

## Code Patterns to Follow
[Key patterns from codebase research]

## Phases
| # | Name | Objective | Est. |
|---|------|-----------|------|

---

## Phase 1: [Name]
### Objective
[Goal]

### Tasks
- [ ] Task with `path/to/file`

### Files
| File | Action |
|------|--------|
