/magic:decide

Record a decision in the analysis journal.

Steps:

1. Read logs/analysis_journal.md to understand current state
2. If arguments provided, record the decision directly
3. If no arguments, ask the user what decision to record:
   • What was the context? (e.g., "Cleaning plan for column X")
   • What options were considered?
   • What was decided and why?
4. Format and append the entry to ## User Decisions in logs/analysis_journal.md:

### Decision: [Brief title]
- **Timestamp:** 2026-04-10T15:30:00+08:00
- **Context:** Sentinel values found in 3,270 rows of `definitions_yue`
- **Options considered:** A. Fill via LLM synthesis, B. Drop rows, C. Flag and skip
- **Chosen:** A — Fill via LLM synthesis
- **Rationale:** Definitions are recoverable from context columns
- **Follow-up:** Route to magic-data-synthesis with fill-sentinels mode

5. If the decision triggers further processing, route to the appropriate skill:
   • Cleaning decisions → magic-data-cleaning
   • Synthesis/fill decisions → magic-data-synthesis
   • Transform decisions → magic-data-transformation
6. Confirm: "Decision recorded. [Next action if applicable]."

Prefixes: [auto] for autonomous mode, [fast-forward] for fast-forwarded decisions.
