Manage Project Context Create and maintain project-context.md to guide AI agents

Use the project-context.md file to ensure AI agents follow your project's technical preferences and implementation rules throughout all workflows. To make sure this is always available, you can also add the line Important project context and conventions are located in [path to project context]/project-context.md to your tools context or always rules file (such as AGENTS.md)

:::note[Prerequisites]

  • BMad Method installed
  • Understanding of your project's technology stack and conventions :::

When to Use This

  • You have strong technical preferences before starting architecture
  • You've completed architecture and want to capture decisions for implementation
  • You're working on an existing codebase with established patterns
  • You notice agents making inconsistent decisions across stories

Step 1: Choose Your Approach

Manual creation — Best when you know exactly what rules you want to document

Generate after architecture — Best for capturing decisions made during solutioning

Generate for existing projects — Best for discovering patterns in existing codebases

Step 2: Create the File

Option A: Manual Creation

Create the file at _bmad-output/project-context.md:

mkdir -p _bmad-output
touch _bmad-output/project-context.md

Add your technology stack and implementation rules:

---
project_name: 'MyProject'
user_name: 'YourName'
date: '2026-02-15'
sections_completed: ['technology_stack', 'critical_rules']
---

# Project Context for AI Agents

## Technology Stack & Versions

- Node.js 20.x, TypeScript 5.3, React 18.2
- State: Zustand
- Testing: Vitest, Playwright
- Styling: Tailwind CSS

## Critical Implementation Rules

**TypeScript:**
- Strict mode enabled, no `any` types
- Use `interface` for public APIs, `type` for unions

**Code Organization:**
- Components in `/src/components/` with co-located tests
- API calls use `apiClient` singleton — never fetch directly

**Testing:**
- Unit tests focus on business logic
- Integration tests use MSW for API mocking

Option B: Generate After Architecture

Run the workflow in a fresh chat:

bmad-generate-project-context

The workflow scans your architecture document and project files to generate a context file capturing the decisions made.

Option C: Generate for Existing Projects

For existing projects, run:

bmad-generate-project-context

The workflow analyzes your codebase to identify conventions, then generates a context file you can review and refine.

Step 3: Verify Content

Review the generated file and ensure it captures:

  • Correct technology versions
  • Your actual conventions (not generic best practices)
  • Rules that prevent common mistakes
  • Framework-specific patterns

Edit manually to add anything missing or remove inaccuracies.

What You Get

A project-context.md file that:

  • Ensures all agents follow the same conventions
  • Prevents inconsistent decisions across stories
  • Captures architecture decisions for implementation
  • Serves as a reference for your project's patterns and rules

Tips

:::tip[Best Practices]

  • Focus on the unobvious — Document patterns agents might miss (e.g., "Use JSDoc on every public class"), not universal practices like "use meaningful variable names."
  • Keep it lean — This file is loaded by every implementation workflow. Long files waste context. Exclude content that only applies to narrow scope or specific stories.
  • Update as needed — Edit manually when patterns change, or re-generate after significant architecture changes.
  • Works for Quick Flow and full BMad Method projects alike. :::
