Review a single file for violations of the lab authoring conventions. The file must be under lab/tasks/ or wiki/.

Steps

1. Parse $ARGUMENTS to get the file path. Accept paths under lab/tasks/ (e.g., lab/tasks/setup.md, lab/tasks/required/task-2.md) or wiki/ (e.g., wiki/web-development.md). If the path is missing or does not point to a file under one of these directories, ask the user.
2. Read the target file.
3. Read the convention files that apply to the target file:
   • For lab/tasks/ files:
     • instructors/context/conventions/common.md — writing conventions (4.1–4.23)
     • instructors/context/conventions/tasks.md — task structure (Section 3) and design principles (Section 12)
   • For wiki/ files:
     • instructors/context/conventions/common.md — writing conventions (4.1–4.23)
     • instructors/context/conventions/wiki.md — wiki file structure and section patterns
4. Go through the target file line by line. Check it against every convention in both files. Flag each violation with its line number.
5. Scan for <!-- TODO ... --> comments. Report each one with its line number and the comment text.
6. Scan for empty sections: a heading immediately followed by another heading, a <!-- TODO ... --> comment, or end of file, with no real content lines in between. Report each empty section with its line number and heading text.

Rules

• The convention files are the single source of truth. Check every rule they contain — do not skip any.
• Do not invent rules beyond what the convention files state.
• Be strict: flag every violation, no matter how small.
• Do not fix anything — only report.
• If a convention does not apply to the file (e.g., the file has no Docker commands), skip that category and note "Not applicable."
• For lab/tasks/setup.md: skip task-only conventions (Section 3 template, acceptance criteria format). Apply all common.md conventions.

Output format

Write the report to tmp/review-via-conventions/<repo-root-path>, where <repo-root-path> is the file's path from the repository root (e.g., tmp/review-via-conventions/lab/tasks/setup.md for lab/tasks/setup.md, tmp/review-via-conventions/wiki/web-development.md for wiki/web-development.md). Create intermediate directories if they do not exist.

The report must be self-contained so another session or agent can act on it without extra context. Structure:

1. Header — file path reviewed, date, convention files used.
2. Findings — grouped by convention number (e.g., "4.2. Terminal commands", "Section 3. Task document structure"). Under each group, list findings as numbered items with line numbers. If a group has no findings, write "No issues found."
3. TODOs — list every <!-- TODO ... --> comment with its line number and text. If none, write "No TODOs found."
4. Empty sections — list every heading that has no content (only a TODO comment, another heading, or EOF follows). Include line number and heading text. If none, write "No empty sections found."
5. Summary — total violation count (conventions + TODOs + empty sections) and a short overall assessment.

After writing the file, print its path in the conversation so the user can find it.
