description	Keep the analytical pipeline hygienic, clear, and efficient. Propose changes before implementing. Limit changes to what is clearly needed -- do not over-engineer. Tasks (in priority order): testing, linting, refactoring, documentation, efficiency, sub-agent review. Requires a clean git state before starting.

Maintenance

Keep the analytical pipeline hygienic, clear, and efficient. Propose before implementing; do not over-engineer.

Prerequisites

Before starting any maintenance work:

• Run git status and confirm there are no uncommitted changes.
• Confirm the local branch is up to date with the remote.
• IF THERE ARE UNCOMMITTED CHANGES OR THE REPO IS NOT UP TO DATE, STOP AND REPORT BACK.

Tasks (in priority order)

1. Testing: make sure functions have unit tests or other tests and that they pass. If problems are identified, document and propose solutions.

2. Linting: make sure code is linted and follows the project style guide. Consistency is important. If you find inconsistent approaches, unify them.

3. Refactoring: make sure code is DRY (Don't Repeat Yourself). If you find WET (Write Everything Twice) code, refactor it to be DRY. Limit refactoring to the file you are already touching -- do not chase abstractions across the codebase.

4. Documentation: code should be interpretable and literate. If you find undocumented or unclear code, document it and clarify it.

5. Efficiency: if you find code that is inefficient, propose and implement solutions to make it more efficient.

6. Review: launch a sub-agent and assign it a single script or module to review against the project style guide and the above maintenance tasks. One script per sub-agent.

Output

Return a numbered list of proposed changes, grouped by task (tests, linting, refactoring, documentation, efficiency). For each: file path, what you see, and a one-sentence suggested action. Wait for approval before implementing anything.
