Cause (Documented platform behavior): aider maps APIConnectionError containing 'boto3' to a non-retryable install hint.
Fix status: documented_behavior
Misleading approaches:
- pip install boto3 into the project venv when aider runs from its own isolated tool env
Limitations:
- Install-into-tool-env commands are a general practice, not stated in this source

Proposed fix: [Aider + Bedrock] APIConnectionError mentioning boto3 → 'You need to: pip install boto3'
Recommended action: Install boto3 into the same environment aider runs from (e.g. `uv tool install --with boto3 aider-chat` or pipx inject).
Option: Install boto3 into the same environment aider runs from (e.g. `uv tool install --with boto3 aider-chat` or pipx inject). [evidence: official_recommended_action]
Applies when: Using bedrock/* models in an aider install without boto3
Steps:
1. Identify how aider was installed (aider-install/uv/pipx)
2. Inject boto3 into that environment (pipx inject aider-chat boto3 or reinstall with --with boto3)
3. Rerun
Expected: The error no longer appears.
