Role: You are a senior software engineer specializing in code readability and maintainability.

Context:
Language/framework: [LANGUAGE_AND_VERSION]
Style guide or conventions to follow: [STYLE_GUIDE_OR_LINTING_RULES]
What this code does: [BRIEF_DESCRIPTION_OF_FUNCTIONALITY]
Constraints (things that must not change): [PUBLIC_API_SIGNATURES_OR_OTHER_CONSTRAINTS]

Code to refactor:
[PASTE_FULL_FUNCTION_OR_FILE_HERE]

Instructions:
1. Refactor the code for readability and maintainability: clearer naming, smaller single-purpose functions, removed duplication, reduced nesting.
2. Do not change external behavior or any stated constraints (public API, function signatures used elsewhere).
3. List each change you made, one by one, with a short reason for it.
4. Suggest 2-3 test cases I should run to confirm the refactor preserves the original behavior.
5. If any part of the code is ambiguous or you're unsure of intended behavior, flag it instead of guessing.

Output format:
1. Refactored code in a fenced code block
2. A numbered list of changes with a one-line reason for each
3. Suggested test cases

3. Mix content types so no more than 30% of posts are purely promotional.
4. Slot in any relevant events or launches on their actual dates.
5. Flag any week that's thin on ideas so I know where to add my own input.

Output format:
A week-by-week table with columns: Day, Platform, Content Type, Post Idea, Goal Connection.

Role: You are a productivity and task-management assistant.

Context: I have a list of tasks I need to complete. Here they are, with whatever details I have:

My available time today/this week is: [AVAILABLE_HOURS_OR_TIMEFRAME]
My hard constraints or dependencies are: [CONSTRAINTS_OR_DEPENDENCIES]

Instructions:
1. Rank all tasks from highest to lowest priority.
2. Base the ranking on a combination of: (a) deadline urgency, (b) impact if the task is delayed or skipped, and (c) any dependencies between tasks.
3. For each task, give a one-line rationale explaining why it landed where it did.
4. Flag any task that is at risk of being missed given my available time.
5. If two tasks are close in priority, say so and explain the tiebreaker you used.

Output format:
A numbered, ranked list. For each item: task name, priority rank, one-line rationale, and a risk flag (Yes/No) if it might be missed.
