Usage Instructions

When a user requests an Aider configuration for AWS Bedrock or asks to set up Aider with custom settings:

1. **Create the configuration file** at `~/.aider.conf.yml` (or `.aider.conf.yml` in project root for project-specific settings)

2. **Copy the complete configuration**:

```yaml

# https://aider.chat/docs/config/aider_conf.html

# Default Model

model: "bedrock/us.anthropic.claude-sonnet-4-20250514-v1:0"

# AWS Settings

set-env:

- AWS_REGION=us-east-1

- AWS_PROFILE=default

# Recommended

# Use $AIDER_MODEL to select aliases on different computers

alias:

- "kip:bedrock/us.anthropic.claude-3-7-sonnet-20250219-v1:0"

# Behavior

cache-prompts: false

check-update: false

multiline: false

notifications: true

show-release-notes: false

stream: true

suggest-shell-commands: false

watch-files: true

yes-always: true

# Git

# Disabled because of: https://github.com/Aider-AI/aider/issues/3049

gitignore: false

auto-commits: false

dirty-commits: false

# Theme

code-theme: monokai

user-input-color: "#d7af5f"

tool-output-color: "#d0d0d0"

tool-error-color: "#ff8080"

tool-warning-color: "#afd700"

assistant-output-color: "#d0d0d0"

completion-menu-color: "#d0d0d0"

completion-menu-bg-color: "#303030"

completion-menu-current-color: "#585858"

```

3. **Verify AWS credentials** are configured:

- Ensure AWS CLI is installed and configured with `aws configure`

- Verify Bedrock model access in us-east-1 region

- Test with: `aider --model bedrock/us.anthropic.claude-sonnet-4-20250514-v1:0 --version`

4. **Model switching** (optional):

- Use the default Sonnet 4: `aider`

- Switch to Kip (Sonnet 3.7): `AIDER_MODEL=kip aider`

5. **Customization guidance**:

- **Region**: Change `AWS_REGION` if using a different AWS region

- **Profile**: Update `AWS_PROFILE` for multi-account setups

- **Git behavior**: Enable `auto-commits: true` if you prefer automatic commits (note known issue #3049)

- **Theme**: Modify color values to match terminal color scheme

- **Yes-always**: Set to `false` if you prefer confirmation prompts
