Bedrock computer use tools availability

Via Anthropic, Amazon Bedrock provides three computer use tools available via `amazonBedrock.tools`: Bash Tool (run bash commands), Text Editor Tool (view and edit text files), and Computer Tool (control keyboard and mouse). Amazon Bedrock does not support strict mode on tool definitions; setting `strict: true` will be ignored with a warning.

Bedrock Bash tool parameters

Bash tool parameters: `command` (string, the bash command to run, required unless restarting), `restart` (boolean, optional, set true to restart the tool).

Bedrock Text Editor tool for Claude 4 models

For Claude 4 models, use `amazonBedrock.tools.textEditor_20250429()`. Parameters: `command` ('view' | 'create' | 'str_replace' | 'insert' | 'undo_edit'), `path` (string, file/directory path), `file_text` (string, optional, required for 'create'), `insert_line` (number, optional, required for 'insert'), `new_str` (string, optional, for 'str_replace'), `insert_text` (string, optional, required for 'insert'), `old_str` (string, optional, required for 'str_replace'), `view_range` (number[], optional, line range for 'view').

Bedrock Text Editor tool for Claude 3.5 Sonnet and earlier

For Claude 3.5 Sonnet and earlier models, use `amazonBedrock.tools.textEditor_20241022()`. Same parameters as Claude 4 version but supports `undo_edit` command (only for these earlier models).

Bedrock Text Editor tool naming requirement

When using the Text Editor Tool, the tool key in the tools object must match the model: use `str_replace_based_edit_tool` for Claude 4 models, and `str_replace_editor` for Claude 3.5 Sonnet and earlier models.
