Sprint 1 Executor

Execute Sprint 1 tasks for the Fantasy Football Analytics FASA optimization and trade intelligence sprint. This skill provides structured, atomic task execution with validation and progress tracking.

When to Use This Skill

Use this skill proactively when:

• User requests execution of any Sprint 1 task (e.g., "Execute Task 1.1", "Start Sprint 1 Task 2.1")
• User asks to work on FASA optimization, cap space, Sleeper integration, or trade analysis
• User references sprint_1 documentation or task files
• User wants to continue sprint work after a break

Task Execution Workflow

When user requests task execution:

1. Identify the task - Determine which task (1.1 through 3.2) from user request

2. Load task file - Read the corresponding task file from references/:

   Phase 1: Foundation (Complete ✅)

   • Task 1.1: references/01_task_cap_space_foundation.md
   • Task 1.2: references/02_task_sleeper_production_integration.md
   • Task 1.3: references/03_task_fasa_target_mart.md

   Phase 2: FASA Intelligence (Current Focus 🟡)

   • Task 11 (2.4): references/11_task_fa_acquisition_history.md
   • Task 12 (2.5): references/12_task_league_roster_depth.md
   • Task 13 (2.6): references/13_task_enhance_fasa_targets.md
   • Task 1.4: references/04_task_fasa_strategy_notebook.md

   Phase 3: Trade Intelligence (Deferred ⏸️)

   • Task 2.1: references/05_task_historical_backfill.md (🟡 partial)
   • Task 2.2: references/06_task_baseline_valuation_model.md (❌ blocked)
   • Task 2.3: references/07_task_trade_target_marts.md (❌ blocked)
   • Task 2.4: references/08_task_trade_analysis_notebook.md (❌ blocked)

   Phase 4: Automation (Future ⏸️)

   • Task 3.1: references/09_task_github_actions_workflows.md
   • Task 3.2: references/10_task_documentation_polish.md

3. Check dependencies - Review the "Dependencies" section in the task file

   • Verify prerequisite tasks are complete
   • If blocked, inform user and suggest completing prerequisites first

4. Implement the task - Follow the task file's implementation steps:

   • Create/modify all files listed in "Files to Create/Modify" section
   • Use exact code templates and SQL from task file
   • Follow step-by-step implementation guide
   • For Tasks 1.3+ that reference 00_SPRINT_PLAN.md: Load references/00_SPRINT_PLAN.md and extract the full SQL/code from the specified line ranges

5. Validate the implementation - Run all validation commands from task file:

   • Execute validation bash commands exactly as written
   • Verify all success criteria are met
   • Check code quality: make lintcheck, make typecheck, make sqlcheck
   • IMPORTANT: If running make lintfix or make sqlfix, re-run dbt tests afterward to confirm linters didn't break anything
   • Run dbt tests: make dbt-test --select [models]

6. Report results - Communicate clearly to user:

   • ✅ What was implemented
   • ✅ Validation results (pass/fail)
   • ⚠️ Any issues or warnings
   • ❌ Blockers (if any)
   • 📝 Next recommended task (if applicable)

7. Commit changes - Use the suggested commit message from task file:

   • Copy exact commit message from "Commit Message" section
   • Ensure conventional commit format (feat:/docs:/etc.)
   • Reference task number: "Resolves: Sprint 1 Task X.Y"

8. Update progress tracking - After successful commit:

   • Mark task complete in references/README.md (⬜ → ✅)
   • Update references/00_SPRINT_PLAN.md Progress Tracking section
   • Suggest next task if user wants to continue

Task File Structure

Each task file contains these sections (use them in order):

1. Objective - What and why
2. Context - Current state, dependencies, why it matters
3. Files to Create/Modify - Complete code listings with templates
4. Implementation Steps - Step-by-step guide (follow exactly)
5. Success Criteria - Definition of done (validate against this)
6. Validation Commands - Exact bash commands to test
7. Commit Message - Suggested message (use exactly)
8. Notes - Gotchas, tips, future considerations

Special Handling by Task Type

Python Implementation Tasks (1.2, 2.1)

• Create modules in src/ingest/ or src/ff_analytics_utils/
• Create production scripts in scripts/ingest/
• Follow existing patterns from similar files
• Include type hints and docstrings
• Run make lint and make typecheck

dbt Model Tasks (1.1, 1.3, 2.2)

• Create models in dbt/ff_data_transform/models/staging/ or dbt/ff_data_transform/models/core/ or dbt/ff_data_transform/models/marts/
• Always create both .sql and .yml files
• Include comprehensive tests in .yml
• Set EXTERNAL_ROOT environment variable before dbt commands
• Run make sqlcheck for SQL linting
• If running make sqlfix for auto-formatting, always re-run dbt tests to confirm no functional changes
• Validate with make dbt-run --select and make dbt-test --select

Notebook Tasks (1.4, 2.3)

• Create in notebooks/ directory
• Use DuckDB for data loading
• Include visualizations (matplotlib/seaborn)
• Test execution: uv run jupyter nbconvert --execute --to notebook --inplace
• Ensure reproducibility (no hardcoded paths)

GitHub Actions Tasks (3.1)

• Create in .github/workflows/
• Use Discord webhooks (not Slack)
• Test locally with make targets first
• Use environment variables from secrets
• Include workflow_dispatch for manual triggering

Documentation Tasks (3.2)

• Create in docs/analytics/ or docs/dev/
• Include examples and code snippets
• Link from main README
• Follow markdown formatting standards

Environment Setup

Before executing tasks, ensure:

# Set environment variables
export SLEEPER_LEAGUE_ID="1230330435511275520"
export EXTERNAL_ROOT="$PWD/data/raw"

# Verify project dependencies
uv sync

# Verify dbt is working
make dbt-run --select dim_player

Common Validation Patterns

For Python Code

uv run python [script] --help
make lint
make typecheck

For dbt Models

export EXTERNAL_ROOT="$PWD/data/raw"
make dbt-run --select [model_name]
make dbt-test --select [model_name]
dbt show --select [model_name] --limit 10
make sqlcheck

# If running linter auto-fix:
make sqlfix
# IMPORTANT: Re-run tests after linter changes
make dbt-test --select [model_name]

For Data Outputs

ls -lh data/raw/[source]/[dataset]/dt=*/
uv run python -c "
import polars as pl
df = pl.read_parquet('data/raw/[source]/[dataset]/dt=*/*.parquet')
print(df.head())
print(f'Rows: {len(df)}')
"

Progress Reference

Full sprint plan and technical specifications in references/00_SPRINT_PLAN.md.

Key Success Factors

1. Follow task files exactly - They contain complete, tested specifications
2. Validate thoroughly - Run all validation commands, check all success criteria
3. Check dependencies - Don't skip prerequisite tasks
4. Commit atomically - One task = one commit with provided commit message
5. Update tracking - Mark tasks complete in README and sprint plan
6. Report clearly - Tell user what worked, what didn't, what's next

Handling Issues

If validation fails:

1. Review error messages carefully
2. Check common gotchas (see references/README.md)
3. Re-read task file for missed details
4. Verify prerequisites completed
5. Report specific error to user with context

If blocked by dependencies:

1. Identify which prerequisite task is missing
2. Inform user: "Task X.Y requires Task A.B to be complete first"
3. Offer to execute prerequisite task or wait
