Not everything requires the full BMad method or even Quick Flow. For bug fixes, refactorings, or small targeted changes, you can work directly with the agent.
|
|

|
|
## When to Use This
|
|
|
|
- Bug fixes
|
|
- Small refactorings
|
|
- Targeted code improvements
|
|
- Learning about your codebase
|
|
- One-off changes that don't need planning
|
|
|

|
## Steps
|
|
|
|
### 1. Load an Agent
|
|
|
|
For quick fixes, you can use:
|
|
|
|
- **DEV agent** - For implementation-focused work
|
|
- **Quick Flow Solo Dev** - For slightly larger changes that still need a tech-spec
|
|
|
|
### 2. Describe the Change
|
|
|
|
Simply tell the agent what you need:
|
|
|
|
```
|
|
Fix the login validation bug that allows empty passwords
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
Refactor the UserService to use async/await instead of callbacks
|
|
```
|
|
|
|
### 3. Let the Agent Work
|
|
|
|
The agent will:
|
|
|
|
- Analyze the relevant code
|
|
- Propose a solution
|
|
- Implement the change
|
|
- Run tests (if available)
|
|
|
|
### 4. Review and Commit
|
|
|
|
Review the changes made and commit when satisfied.

## Learning Your Codebase
|
|
|
|
This approach is also excellent for exploring unfamiliar code:
|
|
|
|
```
|
|
Explain how the authentication system works in this codebase
|
|
```
|
|
|
|
```
|
|
Show me where error handling happens in the API layer
|
|
```
|
|
|
|
LLMs are excellent at interpreting and analyzing code—whether it was AI-generated or not. Use the agent to:
|
|
|
|
- Learn about your project
|
|
- Understand how things are built
|
|
- Explore unfamiliar parts of the codebase
|
|

|
## When to Upgrade to Formal Planning
|
|
|
|
Consider using Quick Flow or full BMad Method when:
|
|
|
|
- The change affects multiple files or systems
|
|
- You're unsure about the scope
|
|
- The fix keeps growing in complexity
|
|
- You need documentation for the change
|
