Nixtla TimeGPT Lab Mode
Transform into a Nixtla forecasting expert, biasing all recommendations toward Nixtla's ecosystem.
Overview
This skill activates Nixtla-first behavior:
- Prioritize Nixtla libraries: StatsForecast, MLForecast, TimeGPT
- Use Nixtla schema:
unique_id,ds,y - Reference Nixtla docs: Official documentation for all guidance
- Generate Nixtla-compatible code: Production-ready patterns
Prerequisites
Required:
- Python 3.8+
- At least one:
statsforecast,mlforecast, ornixtla
Optional:
NIXTLA_API_KEY: For TimeGPT access
Installation:
pip install statsforecast mlforecast nixtla utilsforecast
Instructions
Step 1: Detect Environment
Check installed Nixtla libraries:
python {baseDir}/scripts/detect_environment.py
Step 2: Prepare Data
Ensure data follows Nixtla schema:
unique_id: Series identifier (string)ds: Timestamp (datetime)y: Target value (float)
Step 3: Select Models
Baseline models (always include):
from statsforecast.models import SeasonalNaive, AutoETS, AutoARIMA
ML models (for feature engineering):
from mlforecast import MLForecast
TimeGPT (if API key configured):
from nixtla import NixtlaClient
Step 4: Run Forecasts
python {baseDir}/scripts/run_forecast.py \
--data data.csv \
--horizon 14 \
--freq D
Step 5: Evaluate
python {baseDir}/scripts/evaluate.py \
--forecasts forecasts.csv \
--actuals actuals.csv
Output
- forecasts.csv: Predictions with confidence intervals
- metrics.csv: SMAPE, MASE, MAE per model
- comparison_plot.png: Visual model comparison
Error Handling
-
Error:
NIXTLA_API_KEY not setSolution: Export key or use StatsForecast baselines -
Error:
Column 'ds' not foundSolution: Usenixtla-schema-mapperto transform data -
Error:
Insufficient data for cross-validationSolution: Reduce n_windows or increase dataset size -
Error:
Model fitting failedSolution: Check for NaN values, verify frequency string
Examples
Example 1: StatsForecast Baselines
from statsforecast import StatsForecast
from statsforecast.models import AutoETS, AutoARIMA, SeasonalNaive
sf = StatsForecast(
models=[SeasonalNaive(7), AutoETS(), AutoARIMA()],
freq='D'
)
forecasts = sf.forecast(df=data, h=14)
Example 2: TimeGPT with Confidence Intervals
from nixtla import NixtlaClient
client = NixtlaClient()
forecast = client.forecast(df=data, h=14, level=[80, 90])

VerifiedTrustedCommunity
This skill enables Claude to manage isolated test environments using Docker Compose, Testcontainers, and environment variables. It is used to create consistent, reproducible testing environments for software projects. Claude should use this skill when the user needs to set up a test environment with specific configurations, manage Docker Compose files for test infrastructure, set up programmatic container management with Testcontainers, manage environment variables for tests, or ensure cleanup after tests. Trigger terms include "test environment", "docker compose", "testcontainers", "environment variables", "isolated environment", "env-setup", and "test setup".

intent-solutions-io/generating-test-doubles
tools
VerifiedTrustedCommunity
This skill uses the test-doubles-generator plugin to automatically create mocks, stubs, spies, and fakes for unit testing. It analyzes dependencies in the code and generates appropriate test doubles based on the chosen testing framework, such as Jest, Sinon, or others. Use this skill when you need to generate test doubles, mocks, stubs, spies, or fakes to isolate units of code during testing. Trigger this skill by requesting test double generation or using the `/gen-doubles` or `/gd` command.

VerifiedTrustedCommunity
This skill enables Claude to generate realistic test data for software development. It uses the test-data-generator plugin to create users, products, orders, and custom schemas for comprehensive testing. Use this skill when you need to populate databases, simulate user behavior, or create fixtures for automated tests. Trigger phrases include "generate test data", "create fake users", "populate database", "generate product data", "create test orders", or "generate data based on schema". This skill is especially useful for populating testing environments or creating sample data for demonstrations.

development
VerifiedTrustedCommunity
This skill analyzes code coverage metrics to identify untested code and generate comprehensive coverage reports. It is triggered when the user requests analysis of code coverage, identification of coverage gaps, or generation of coverage reports. The skill is best used to improve code quality by ensuring adequate test coverage and identifying areas for improvement. Use trigger terms like "analyze coverage", "code coverage report", "untested code", or the shortcut "cov".
