+description: >-
+  Provides a systematic 5-step workflow for improving WorldQuant BRAIN alphas.
+  Includes steps for gathering alpha info, evaluating datafields, proposing idea-focused improvements (using arXiv), simulating variants, and validating.
+  Use when the user wants to improve an existing alpha or fix failing submission tests.

+
+# Alpha Improvement Workflow
+
+This repeatable workflow enhances alphas by focusing on core idea refinements rather than just mechanical tweaks.
+For the detailed steps, analysis techniques, and best practices, see [reference.md](reference.md).
+
+## Step 1: Gather Alpha Information (5-10 mins)
+**Goal**: Identify weaknesses (low Sharpe, high correlation, etc.).
+- Fetch alpha details (`get_alpha_details`).
+- Check PnL, Sharpe, Fitness, Turnover.
+- Run submission checks (`get_submission_check`) and correlation checks (`check_correlation`).
+
+## Step 2: Evaluate Core Datafield(s) (5-10 mins)
+**Goal**: Understand data properties (sparsity, frequency).
+- Run 6 evaluation simulations (Coverage, Non-Zero, Update Frequency, Bounds, Central Tendency, Distribution) using `brain-datafield-exploration` skill methods.
+
+## Step 3: Propose Idea-Focused Improvements (10-15 mins)
+**Goal**: Evolve the signal with theory-backed concepts.
+- Review docs for tips (ATOM principle, flipping negatives).
+- Search arXiv for concepts (e.g., "persistence", "momentum").
+- Brainstorm 4-6 variants (e.g., add decay, change normalization).
+
+## Step 4: Simulate and Test Variants (10-20 mins)
+**Goal**: Compare ideas via metrics.
+- Use `create_multiSim` to test variants.
+- Compare Fitness, Sharpe, and Sub-universe performance.
+
+## Step 5: Validate and Iterate (5-10 mins)
+**Goal**: Confirm submittability.
+- Run final checks.
+- If failing, repeat from Step 3 with new ideas.
+- If passing, submit!
+
+## Best Practices
+- **Cycle Limit**: 3-5 iterations per alpha.
+- **Focus**: 70% on ideas, 30% on parameter tweaks.
+- **Goal**: Passing checks + stable yearly stats.
