"description": "Replaces text within a file. By default, replaces a single occurrence, but can replace multiple occurrences when `expected_replacements` is specified. This tool requires providing significant context around the change to ensure precise targeting. Always use the read_file tool to examine the file's current content before attempting a text replacement.\n \n The user has the ability to modify the `new_string` content. If modified, this will be stated in the response.\n \n Expectation for required parameters:\n 1. `old_string` MUST be the exact literal text to replace (including all whitespace, indentation, newlines, and surrounding code etc.).\n 2. `new_string` MUST be the exact literal text to replace `old_string` with (also including all whitespace, indentation, newlines, and surrounding code etc.). Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed. It is important to Make it specific and detailed so developers or large language models can understand what needs to be changed and perform the changes on their own if necessary. \n 4. NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool. Always check the content of the file after changes or not finding a string to match.\n **Multiple replacements:** Set `expected_replacements` to the number of occurrences you want to replace. The tool will replace ALL occurrences that match `old_string` exactly. Ensure the number of replacements matches your expectation.",

I will verify this through data inspection after implementing the initial modifications.",

Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed. It is important to Make it specific and detailed so developers or large language models can understand what needs to be changed and perform the changes on their own if necessary. \n 4. NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool. Always check the content of the file after changes or not finding a string to match.\n **Multiple replacements:** Set `expected_replacements` to the number of occurrences you want to replace. The tool will replace ALL occurrences that match `old_string` exactly. Ensure the number of replacements matches your expectation.",

"description": "Replaces text within a file. By default, replaces a single occurrence, but can replace multiple occurrences when `expected_replacements` is specified. This tool requires providing significant context around the change to ensure precise targeting. Always use the read_file tool to examine the file's current content before attempting a text replacement.\n \n The user has the ability to modify the `new_string` content. If modified, this will be stated in the response.\n \n Expectation for required parameters:\n 1. `old_string` MUST be the exact literal text to replace (including all whitespace, indentation, newlines, and surrounding code etc.).\n 2. `new_string` MUST be the exact literal text to replace `old_string` with (also including all whitespace, indentation, newlines, and surrounding code etc.). Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed. It is important to Make it specific and detailed so developers or large language models can understand what needs to be changed and perform the changes on their own if necessary. \n 4. NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool. Always check the content of the file after changes or not finding a string to match.\n **Multiple replacements:** Set `expected_replacements` to the number of occurrences you want to replace. The tool will replace ALL occurrences that match `old_string` exactly. Ensure the number of replacements matches your expectation.",

Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed.

NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool.

"description": "Replaces text within a file. By default, replaces a single occurrence, but can replace multiple occurrences when `expected_replacements` is specified. This tool requires providing significant context around the change to ensure precise targeting. Always use the read_file tool to examine the file's current content before attempting a text replacement.\n \n The user has the ability to modify the `new_string` content. If modified, this will be stated in the response.\n \n Expectation for required parameters:\n 1. `old_string` MUST be the exact literal text to replace (including all whitespace, indentation, newlines, and surrounding code etc.).\n 2. `new_string` MUST be the exact literal text to replace `old_string` with (also including all whitespace, indentation, newlines, and surrounding code etc.). Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed. It is important to Make it specific and detailed so developers or large language models can understand what needs to be changed and perform the changes on their own if necessary. \n 4. NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool. Always check the content of the file after changes or not finding a string to match.\n **Multiple replacements:** Set `expected_replacements` to the number of occurrences you want to replace. The tool will replace ALL occurrences that match `old_string` exactly. Ensure the number of replacements matches your expectation.",

"output": "# Gemini CLI Project Context - AWS Organization Audit Scripts\n\n## Project Overview\nThis repository contains a collection of Python scripts for auditing AWS Organizations. It handles multi-account discovery, SSO authentication, and generates reports on costs, bandwidth, and resource inventory.\n\n## Core Guidelines\n\n- **Shared Logic:** All AWS interaction MUST go through `aws_utils.py`. Never initialize `boto3.client` directly without first ensuring a session via `aws_utils`.\n- **Authentication:** Use `ensure_sso_login()` to handle AWS SSO sessions. This triggers `aws sso login` via the CLI if the session is expired.\n- **Session Management:** \n - Use `get_boto_session()` for parent/management account tasks (Organizations, Pricing API).\n - Use `setup_org_accounts_session()` to iterate through accounts in specific OUs or the entire organization. This handles profile switching for multi-account scans and unsets conflicting IAM env vars.\n- **Configuration:** \n - Honor environment variables: `AWS_PARENT_PROFILE`, `OU_IDS`, `SKIP_ACCOUNTS`, `GOOGLE_CLIENT_SECRET_FILE`, and `GOOGLE_AUTHORIZED_USER_FILE`.\n - Support `.env` files via `python-dotenv` (handled in `aws_utils.py`).\n- **Reporting:** \n - For large datasets, prefer CSV output using the `csv` module.\n - **Google Sheets:** Use `export_to_sheets(title, headers, rows)` from `aws_utils.py` to automatically export CSV data to Google Sheets.\n - For console summaries, use formatted tables with `print` or `pandas`.\n\n## Key Patterns\n\n### Account Iteration\nAlways use the generator pattern for cross-account audits:\n```python\nfrom aws_utils import setup_org_accounts_session\nfor account, profile_name in setup_org_accounts_session():\n boto3.setup_default_session(profile_name=profile_name)\n # ... account-specific logic ...\n```\n\n### Date Handling\nStandardize billing periods using `aws_utils.py` helpers:\n- `get_previous_month_range()`: Returns `(start, end)` for the last full month.\n- `get_last_n_months_ranges(n)`: Returns list of ranges for historical analysis.\n\n### Testing\n- Place tests in the `tests/` directory.\n- Use `unittest` and `unittest.mock`.\n- **Mocks:** Always mock `aws_utils.get_boto_session` and AWS clients to ensure tests run without credentials or network access.\n\n## Tooling & Dependencies\n- **Primary:** `boto3`, `pandas`, `python-dotenv`.\n- **Secondary:** `gspread`, `google-auth-oauthlib` (for Google Sheets reports).\n- **Environment:** Always execute within the project's virtual environment (`.venv`).\n\n## Security & Privacy\n- **Identifiers:** Never hardcode Account IDs, OU IDs, or Profile Names. Use the configuration patterns in `aws_utils`.\n- **Sanitization:** When creating examples or documentation, use generic placeholders like `ou-1234-abcd5678` or `123456789012`.\n- **Environment:** Do not commit `.env` files or Google authentication JSON files (`client_secret.json`, `authorized_user.json`).\n"

The resulting token is saved to `authorized_user.json`.\n\nIf these files are missing, the scripts will skip the Google Sheets export and only produce CSVs.\n\n## Script Overview\n\nThe project uses a shared `aws_utils.py` module to handle SSO login, date ranges, and account iteration.\n\n### Cost & Billing\n- `aws_bills.py`: Comparison of Amortized and Unblended costs over the last 3 months.\n- `aws_cost.py`: Detailed EC2 cost report including compute savings.\n- `bwsuage.py`: Monthly bandwidth usage report with overage alerts (>100GB).\n- `storage-usage.py`: Monthly storage report (S3, EBS, RDS, EFS).\n- `generate-billing-sheets.py`: Generates detailed Google Sheets reports (requires Google API credentials).\n- `summarize-ecsv.py`: Parses exported AWS billing CSV files for local analysis.\n\n### Resource Inventory\n- `aws-vpc.py`: Lists VPCs and CIDR blocks across all accounts/regions.\n- `aws-ips.py`: Lists public IPs, EIPs, and internet-facing Load Balancer DNS names.\n- `list_rds_instances.py`: Lists all RDS instances and clusters.\n- `cloudfront.py`: Lists CloudFront distributions and their status.\n- `aws-asg-lt-ami.py`: Audits Auto Scaling Groups, Launch Templates, and associated AMIs.\n- `aws-ec2-ami.py`: Inventories running EC2 instances and their AMI IDs.\n\n### Pricing\n- `ec2_price.py`: Fetches current on-demand pricing for T3 instance families in London.\n- `rds_price.py`: Fetches current on-demand pricing for RDS MySQL/PostgreSQL in London.\n\n## Usage\n\nMost scripts run autonomously once your `.env` is configured:\n```bash\npython <script_name>.py\n```\nIf your AWS SSO session has expired, the scripts will automatically attempt to trigger `aws sso login` using your defined parent profile.\n\n## Contributing\n\nWhen adding new scripts, leverage `aws_utils.py` for:\n- `setup_org_accounts_session()`: Iterates through accounts in your OUs.\n- `ensure_sso_login()`: Handles session validation.\n- `get_previous_month_range()`: Standardizes billing periods.\n",

"description": "Replaces text within a file. By default, replaces a single occurrence, but can replace multiple occurrences when `expected_replacements` is specified. This tool requires providing significant context around the change to ensure precise targeting. Always use the read_file tool to examine the file's current content before attempting a text replacement.\n \n The user has the ability to modify the `new_string` content. If modified, this will be stated in the response.\n \n Expectation for required parameters:\n 1. `old_string` MUST be the exact literal text to replace (including all whitespace, indentation, newlines, and surrounding code etc.).\n 2. `new_string` MUST be the exact literal text to replace `old_string` with (also including all whitespace, indentation, newlines, and surrounding code etc.). Ensure the resulting code is correct and idiomatic and that `old_string` and `new_string` are different.\n 3. `instruction` is the detailed instruction of what needs to be changed. It is important to Make it specific and detailed so developers or large language models can understand what needs to be changed and perform the changes on their own if necessary. \n 4. NEVER escape `old_string` or `new_string`, that would break the exact literal text requirement.\n **Important:** If ANY of the above are not satisfied, the tool will fail. CRITICAL for `old_string`: Must uniquely identify the single instance to change. Include at least 3 lines of context BEFORE and AFTER the target text, matching whitespace and indentation precisely. If this string matches multiple locations, or does not match exactly, the tool will fail.\n 5. Prefer to break down complex and long changes into multiple smaller atomic calls to this tool. Always check the content of the file after changes or not finding a string to match.\n **Multiple replacements:** Set `expected_replacements` to the number of occurrences you want to replace. The tool will replace ALL occurrences that match `old_string` exactly. Ensure the number of replacements matches your expectation.",
