description	Conceptual solution design for a task in engineering-log: read TASK_DIR/01-problem-statement-formal.md when it exists and is non-empty, otherwise fall back to TASK_DIR/01-problem-statement.md, choose a mode (explore solution space or use a single obvious option), run the corresponding guided dialogue, and write results to 02-solution-options.md / 03-solution-hld.md and chats/*.

Process step: engineering-log solution design

Input

• TASK_DIR is the task base directory (a repo-relative path or an absolute path).
• The working problem statement file must be selected in this order:
  • TASK_DIR/01-problem-statement-formal.md when it exists and is non-empty.
  • Otherwise TASK_DIR/01-problem-statement.md.
• At least one of those files must exist and contain the problem statement.

Output

• Mode space (solution space exploration):
  • TASK_DIR/02-solution-options.md
  • TASK_DIR/03-solution-hld.md
  • TASK_DIR/chats/02-solution-options-chat-1.md
• Mode single (single obvious option):
  • TASK_DIR/03-solution-hld.md
  • TASK_DIR/chats/02-solution-hld-chat-1.md

Algorithm

1) Determine the task directory

• If the user did not provide TASK_DIR, ask for it.
• Select the working problem statement file:
  • Use TASK_DIR/01-problem-statement-formal.md when it exists and is non-empty.
  • Otherwise use TASK_DIR/01-problem-statement.md.
• If neither file is available with content, stop and ask for the correct path.
• If TASK_DIR/chats/ does not exist, create it.

2) Choose the mode: space or single

Read the selected working problem statement file, then do a quick classification.

Choose space if any of these is true:

• there are 2+ reasonable approaches and you need to choose deliberately;
• requirements/constraints are incomplete and you cannot proceed without Q&A;
• the cost of a wrong decision is high (wide changes, high regression risk, complex integration).

Choose single if:

• the solution is truly obvious and alternatives are not meaningful;
• scope boundaries are clear and the choice does not affect architecture/contracts.

If in doubt, default to proposing space.

After classification:

• briefly explain why this mode fits;
• ask the user to confirm the mode: space or single.

3) Follow the corresponding prompt strictly

• Set {{PROBLEM_STATEMENT_FILE}} to the selected working problem statement file before following the prompt.
• If space is chosen, open and follow references/exec-spec-space.md.
• If single is chosen, open and follow references/exec-spec-single.md.

Do not mix prompts. Do not violate their stop points and file-writing rules. Write TASK_DIR/02-solution-options.md (if applicable) and TASK_DIR/03-solution-hld.md in English.

Transcript export

Both prompts require saving the current chat transcript into TASK_DIR/chats/.... Append to the transcript as you go, after each completed step, instead of waiting until the end. If you cannot save the transcript automatically, do not fabricate it. Ask the user to help, or use the exporting-chat-artifacts skill.
