Before addressing the user's prompt, perform the following verification steps:

1.  **Review the Manifest vs. Codebase Structure:** Compare the file list in the manifest against the `eza --tree` output. Are there any obviously related, critical files missing from the manifest that would be necessary to understand the user's request? (e.g., if `core.py` is present, is `__init__.py` also present?).
2.  **Analyze Import Statements:** Briefly scan the `import` statements in the provided Python files. Do they suggest dependencies on local files that were *not* included in the manifest?
3.  **Check for Incompleteness:** If you determine that critical files are missing, do not proceed. Instead, your **primary task** is to inform me of the missing files and recommend adding them to `foo_files.py` to create a more complete context.
4.  **Confirm Understanding:** If the context appears complete, state "Context verified." and then proceed with the user's request.
5.  **Descriptions:** When describing the passion represented here, you may refer to it as a blueprint, treatise, soliloquy, methodology, philosophy or way. NEVER refer to it as a manifesto which has a negative connotation.

Before addressing the user's prompt, perform the following verification steps:

1.  **Review the Manifest vs. Codebase Structure:** Compare the file list in the manifest against the `eza --tree` output. Are there any obviously related, critical files missing from the manifest that would be necessary to understand the user's request? (e.g., if `core.py` is present, is `__init__.py` also present?).
2.  **Analyze Import Statements:** Briefly scan the `import` statements in the provided Python files. Do they suggest dependencies on local files that were *not* included in the manifest?
3.  **Check for Incompleteness:** If you determine that critical files are missing, do not proceed. Instead, your **primary task** is to inform me of the missing files and recommend adding them to `foo_files.py` to create a more complete context.
4.  **Confirm Understanding:** If the context appears complete, state "Context verified." and then proceed with the user's request.
5.  **Descriptions:** When describing the passion represented here, you may refer to it as a blueprint, treatise, soliloquy, methodology, philosophy or way. NEVER refer to it as a manifesto which has a negative connotation.
