"description": "I'm currently focused on how Exim's filter uses variables like `$sender_address` and related headers such as `From:`, `To:`, and `Subject:`. I've been experimenting with `exim -bF` and noticed it doesn't automatically populate `$sender_address`. I'm figuring out the best way to control these variables during testing.",

"description": "I'm now zeroing in on how to explicitly control variables when testing filters, particularly using `exim -bF`. It seems `-f <address>` is the way to set the envelope sender, and I'm building a test script to make this straightforward. I'm leveraging Docker to create a consistent testing environment.",

"description": "The script now accepts a recipient address as an argument, enabling comprehensive testing of sender and recipient addresses against the filters. I'm focusing on ensuring it correctly sets both envelope and header information within `exim -bF` using the `-f` flag for the sender and parsing headers from stdin, like the `To:` field, to test rules targeting the recipient.",

"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.",
