"content": "\nYou are an AI agent that brings the power of Gemini directly into the terminal. Your task is to analyze the current directory and generate a comprehensive GEMINI.md file to be used as instructional context for future interactions.\n\n**Analysis Process:**\n\n1. **Initial Exploration:**\n * Start by listing the files and directories to get a high-level overview of the structure.\n * Read the README file (e.g., `README.md`, `README.txt`) if it exists. This is often the best place to start.\n\n2. **Iterative Deep Dive (up to 10 files):**\n * Based on your initial findings, select a few files that seem most important (e.g., configuration files, main source files, documentation).\n * Read them. As you learn more, refine your understanding and decide which files to read next. You don't need to decide all 10 files at once. Let your discoveries guide your exploration.\n\n3. **Identify Project Type:**\n * **Code Project:** Look for clues like `package.json`, `requirements.txt`, `pom.xml`, `go.mod`, `Cargo.toml`, `build.gradle`, or a `src` directory. If you find them, this is likely a software project.\n * **Non-Code Project:** If you don't find code-related files, this might be a directory for documentation, research papers, notes, or something else.\n\n**GEMINI.md Content Generation:**\n\n**For a Code Project:**\n\n* **Project Overview:** Write a clear and concise summary of the project's purpose, main technologies, and architecture.\n* **Building and Running:** Document the key commands for building, running, and testing the project. Infer these from the files you've read (e.g., `scripts` in `package.json`, `Makefile`, etc.). If you can't find explicit commands, provide a placeholder with a TODO.\n* **Development Conventions:** Describe any coding styles, testing practices, or contribution guidelines you can infer from the codebase.\n\n**For a Non-Code Project:**\n\n* **Directory Overview:** Describe the purpose and contents of the directory. What is it for? What kind of information does it hold?\n* **Key Files:** List the most important files and briefly explain what they contain.\n* **Usage:** Explain how the contents of this directory are intended to be used.\n\n**Final Output:**\n\nWrite the complete content to the `GEMINI.md` file. The output must be well-formatted Markdown.\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.",

This includes `terraform-docs`, `tfsec`, `tflint`, and `act`.\n\n### Key Commands\n- **Initialization:** `terraform init`\n- **Validation:** `terraform validate`\n- **Planning:** `terraform plan`\n- **Applying:** `terraform apply`\n- **Formatting:** `terraform fmt -recursive` (CI uses `fmt -check=true -diff=true`)\n- **Documentation:** `terraform-docs` is used to automatically generate the `README.md` content between the `BEGIN_TF_DOCS` and `END_TF_DOCS` markers.\n- **Local CI Testing:** `scripts/test.sh` runs `act -n` to simulate GitHub Actions locally.\n- **Linting:** `tflint -f compact`\n- **Security Scan:** `tfsec`\n\n## Development Conventions\n\n- **File Structure:** \n - Terraform resources are organized into separate files by function (e.g., `vpc-infrastructure.tf`, `ecs-cluster-infrastructure.tf`).\n - `locals.tf` contains complex logic for resource naming, tagging, and feature flags.\n - Template files are stored in subdirectories like `policies/`, `ec2-userdata/`, and `buildspecs/`.\n- **Naming & Tagging:** \n - A standard `resource_prefix` is used: `${project_name}-${infrastructure_name}-${environment}`.\n - Default tags include `Project`, `Infrastructure`, `Environment`, and `Prefix`.\n- **Infrastructure as Code Standards:**\n - Always run `terraform fmt` before committing.\n - Documentation must be updated via `terraform-docs` (this is enforced in CI).\n - Use the provided template files (`.tpl`) for IAM policies and ECS task definitions to ensure consistency.\n- **Testing:** \n - New features should be verified with `terraform validate` and ideally a `terraform plan`.\n - GitHub Actions will run validation, format checks, linting, and security scans on all pull requests.\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.",

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.

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.

"description": "Replaces text within a file. By default, the tool expects to find and replace exactly ONE occurrence of `old_string`. If you want to replace multiple occurrences of the exact same string, set `allow_multiple` to true. 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 instance(s) 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 and `allow_multiple` is not true, 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 `allow_multiple` to true if you want to replace ALL occurrences that match `old_string` exactly.",
