Use when analyzing trends over time, detecting seasonality, identifying anomalies in time series, or building simple forecasting models for planning.\n---\n\n# Time Series Analysis\n\n# When to use\n- Building a forecast for operational planning (staffing, inventory, infrastructure capacity)\n- Identifying whether a trend is genuine or driven by seasonality\n- Detecting anomalies in a metric stream (traffic spikes, revenue dips, error rate surges)\n- Providing a \"what would have happened\" baseline for measuring initiative impact\n- Presenting year-over-year growth in a way that accounts for seasonal patterns\n\n# Process\n1. **Load and inspect the time series** — confirm regular intervals (fill gaps if needed), check for obvious data quality issues (negative values, zeros in non-zero series), and identify the natural granularity (daily, weekly, monthly).\n2. **Test for stationarity** — run an ADF test. If non-stationary (trend or seasonality present), note this — it informs decomposition and model choice rather than blocking analysis. See `references/ts_patterns_guide.md`.\n3. **Decompose into components** — separate the time series into trend, seasonal, and residual using additive or multiplicative decomposition. Measure the strength of each component (0–1). Strong seasonality (>0.6) means raw values are misleading without seasonal adjustment.\n4. **Detect anomalies** — flag points more than 3 standard deviations from the rolling median. Investigate the top 5 anomalies against the event log (product releases, campaigns, incidents). Use `scripts/ts_analyzer.py --detect-anomalies`.\n5. **Fit a forecast model** — fit an ARIMA model (or simpler moving average if data is short). Validate on a held-out 20% test set and report MAPE. Generate point estimates and 95% confidence intervals for the forecast horizon.\n6. **Produce the analysis report** — summarise trend direction and strength, seasonal patterns and their business implications, anomaly findings, and the forecast with uncertainty. Use `assets/ts_report_template.md`.\n\n# Inputs the skill needs\n- Time series data: date column + one numeric metric column, minimum 2 full seasonal cycles\n- Granularity of the data (daily, weekly, monthly)\n- Forecast horizon required (days, weeks, months ahead)\n- Event log or change log for anomaly investigation\n- Business context: what drives this metric, known seasonal patterns\n\n# Output\n- `scripts/ts_analyzer.py` — decomposes, detects anomalies, and fits an ARIMA forecast; outputs charts and CSV\n- `references/ts_patterns_guide.md` — stationarity, seasonality types, model selection guide, and common pitfalls\n- `assets/ts_report_template.md` — report template: characteristics, decomposition summary, anomaly list, forecast table, insights\n","tagline":"Temporal pattern detection and forecasting.
