-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Custom Apache Airflow operators for TimeGPT and StatsForecast integration. Enables data engineering teams to embed Nixtla forecasting directly into production data pipelines with proper monitoring, retry logic, and observability.
 
-**Full Specification:** [`../../012-AT-ARCH-plugin-04-nixtla-airflow-operator.md`](../../012-AT-ARCH-plugin-04-nixtla-airflow-operator.md)
+---
+
+## Problem Statement
+
+Enterprise data platform integration gap:
+> "Data engineering teams run everything through Airflow. Without a native operator, they're writing custom Python operators that lack production-grade error handling, retry logic, and monitoring."
+
+This plugin provides first-class Airflow integration for enterprise data platforms.
+
+---
+
+## Goals
+
+1. Provide native Airflow operators for TimeGPT and StatsForecast
+2. Include production-grade retry logic and error handling
+3. Support connection management through Airflow connections
+4. Enable monitoring via Airflow task metrics
+5. Integrate with existing data warehouse operators (BigQuery, Snowflake, Redshift)
+
+## Non-Goals
+
+- Replace custom ML pipeline orchestration
+- Support non-Airflow orchestrators (Dagster, Prefect)
+- Handle model training/fine-tuning
+- Provide GUI-based DAG building
+
+---
+
+## Target Users
+
+| User | Need |
+|------|------|
+| Data engineers | Integrate forecasting into existing DAGs |
+| Platform teams | Standardize forecasting across organization |
+| MLOps engineers | Production-grade forecasting pipelines |
+| DataOps teams | Scheduling and monitoring forecasts |
+
+---
+
+## Functional Requirements
+
+### FR-1: TimeGPT Operator
+- `TimeGPTForecastOperator` - Generate forecasts via API
+- Support all TimeGPT parameters (horizon, freq, level)
+- Handle API rate limiting and retries
+- Return forecasts to XCom for downstream tasks
+
+### FR-2: StatsForecast Operator
+- `StatsForecastOperator` - Run local statistical models
+- Support model selection (AutoARIMA, AutoETS, etc.)
+- Handle large datasets with chunking
+- Support parallel processing configuration
+
+### FR-3: Connection Management
+- Custom Airflow connection type for Nixtla
+- Secure API key storage
+- Support multiple environments (dev, staging, prod)
+
+### FR-4: Data Source Integration
+- `NixtlaBigQueryOperator` - Read from BigQuery, forecast, write back
+- `NixtlaSnowflakeOperator` - Snowflake integration
+- `NixtlaS3Operator` - S3 input/output support
+
+### FR-5: Monitoring & Observability
+- Task duration metrics
+- Forecast count tracking
+- API cost estimation per run
+- Alert on accuracy degradation
+
+---
+
+## Non-Functional Requirements
+
+### NFR-1: Compatibility
+- Apache Airflow 2.6+
+- Python 3.10+
+- Support Composer, MWAA, Astronomer
+
+### NFR-2: Performance
+- Batch API calls for efficiency
+- Configurable parallelism
+- Memory-efficient for large datasets
+
+### NFR-3: Reliability
+- Exponential backoff retry logic
+- Circuit breaker for API failures
+- Graceful degradation options
+
+---
+
+## User Stories
+
+### US-1: Daily Demand Forecasting DAG
+> "As a data engineer, I want to add forecasting to my daily retail DAG so I can generate demand forecasts alongside inventory updates."
+
+**Acceptance:**
+- Drop-in operator for existing DAGs
+- Configurable via Airflow variables
+- Output to BigQuery/Snowflake

-- Overview
-- Goals & Non-Goals
-- User Stories
-- Functional Requirements
-- Non-Functional Requirements
-- Success Metrics
-- Scope
+### US-2: Multi-Tenant Forecasting
+> "As a platform engineer, I want to run forecasts for 100+ tenants in a single DAG so I can scale without managing individual pipelines."
+
+**Acceptance:**
+- Support dynamic task mapping
+- Per-tenant configuration
+- Aggregate cost tracking
+
+### US-3: Monitoring Integration
+> "As an MLOps engineer, I want forecasting metrics in Datadog/Prometheus so I can monitor pipeline health alongside other ML systems."
+
+**Acceptance:**
+- Export standard metrics
+- Support custom metric labels
+- Alert on anomalies

-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Claude Code plugin that wraps Nixtla's existing Snowflake Native App integration, providing one-command SQL-native forecasting with automatic setup, error handling, and result formatting. Enables SQL analysts to use TimeGPT without writing Python.
 
-**Full Specification:** [`../../014-AT-ARCH-plugin-06-nixtla-snowflake-adapter.md`](../../014-AT-ARCH-plugin-06-nixtla-snowflake-adapter.md)
+---
+
+## Problem Statement
+
+Integration tax friction:
+> "Marketing copy attacks Python infrastructure requirements. This plugin makes the native Snowflake integration discoverable and easy to use from Claude Code."
+
+This plugin is a wrapper/helper for the existing Nixtla Snowflake integration.
+
+---
+
+## Goals
+
+1. Simplify Snowflake Native App usage via Claude Code
+2. Generate correct SQL for CALL NIXTLA_FORECAST(...)
+3. Validate Snowflake connections and permissions
+4. Format results for BI tools (Looker, Tableau)
+5. Provide clear error messages and troubleshooting
+
+## Non-Goals
+
+- Replace the Nixtla Snowflake Native App
+- Handle non-Snowflake data warehouses
+- Provide Python-based forecasting
+- Manage Snowflake infrastructure
+
+---
+
+## Target Users
+
+| User | Need |
+|------|------|
+| SQL analysts | Forecasting without Python |
+| BI developers | Forecasts for dashboards |
+| Data teams | Snowflake-native forecasting |
+| Snowflake admins | Easy TimeGPT setup |
+
+---
+
+## Functional Requirements
+
+### FR-1: Connection Validation
+- Test Snowflake connection credentials
+- Verify Nixtla Native App installation
+- Check user permissions for forecasting
+- Provide setup instructions if not installed
+
+### FR-2: SQL Generation
+- Generate CALL NIXTLA_FORECAST(...) SQL

-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Automated benchmarking tool that runs side-by-side comparisons between TimeGPT (API) and StatsForecast (OSS) on user's actual data. Generates comprehensive accuracy reports with sMAPE, MASE, and other metrics to help users choose the right tool for their use case.
 
-**Full Specification:** [`../../010-AT-ARCH-plugin-02-nixtla-vs-statsforecast-benchmark.md`](../../010-AT-ARCH-plugin-02-nixtla-vs-statsforecast-benchmark.md)
+---
+
+## Problem Statement
+
+Free tier trap:
+> "Users start with free StatsForecast, get decent results, and never try TimeGPT because 'good enough' feels safe. They don't know TimeGPT might be 20% more accurate on their data."
+
+This plugin provides evidence-based comparison to drive TimeGPT adoption.
+
+---
+
+## Goals
+
+1. Run automated benchmarks comparing StatsForecast vs TimeGPT
+2. Generate accuracy comparison reports (sMAPE, MASE, RMSE)
+3. Identify use cases where TimeGPT significantly outperforms
+4. Quantify the accuracy-cost trade-off
+5. Provide data-driven recommendation
+
+## Non-Goals
+
+- Replace comprehensive model evaluation processes
+- Guarantee accuracy improvements
+- Compare against non-Nixtla libraries
+- Provide production-ready model selection
+
+---
+
+## Target Users
+
+| User | Need |
+|------|------|
+| Data scientists | Evidence-based model selection |
+| ML engineers | Accuracy vs cost trade-off analysis |
+| Technical evaluators | Vendor comparison data |
+| Nixtla sales | Proof points for TimeGPT value |
+
+---
+
+## Functional Requirements
+
+### FR-1: Data Ingestion

+- Manual setup of statsforecast models
+- Custom code to load M4 competition data
+- Ad-hoc metric calculation (sMAPE, MASE)
+- No standardized comparison framework
+
+## Solution
+
+A Claude Code plugin that runs statistical baseline models (AutoETS, AutoTheta, SeasonalNaive) on M4 benchmark data with standardized metric reporting.
+
+---
+
+## Target Users
+
+1. **Nixtla Team**: Validate statsforecast performance on standard benchmarks
+2. **Data Scientists**: Establish baselines before evaluating TimeGPT
+3. **ML Engineers**: Compare model accuracy using industry-standard metrics
+
+---
+
+## Value Proposition
+
+| Without Plugin | With Plugin |
+|---------------|-------------|
+| Hours to set up baseline tests | 30-second smoke test |
+| Manual metric calculation | Automated sMAPE/MASE |
+| No reproducibility | Standardized test harness |
+| Custom code per benchmark | Single slash command |
+
+---
+
+## Success Metrics
+
+| Metric | Target | Current |
+|--------|--------|---------|
+| Smoke test pass rate | 100% | 100% |
+| Time to run baseline | <90 seconds | ~30 seconds |
+| M4 datasets supported | 4 (Daily, Hourly, Monthly, Weekly) | 4 |
+
+---
+
+## Competitive Landscape
+
+No direct competitors exist for this specific use case. Alternatives:
+- Manual statsforecast scripts (time-consuming)
+- M4 competition code (not integrated with Claude Code)
+
+---
+
+## Recommendation
+
+**Status: IMPLEMENTED** - Plugin is working and tested. Primary use is internal validation and demos.

+```
+
+---
+
+## Component Design
+
+### MCP Server (`scripts/nixtla_baseline_mcp.py`)
+
+Exposes 4 tools to Claude Code:
+
+| Tool | Purpose | Inputs | Outputs |
+|------|---------|--------|---------|
+| `run_baselines` | Execute models on data | CSV path, horizon | Metrics CSV |
+| `get_nixtla_compatibility_info` | Check library versions | None | Version dict |
+| `generate_benchmark_report` | Create markdown report | Metrics CSV | Markdown |
+| `generate_github_issue_draft` | Generate issue template | Metrics, context | Markdown |
+
+### Data Layer
+
+M4 competition data stored locally:
+
+```
+data/m4/
+├── M4-Daily.csv     # 4,227 series
+├── M4-Hourly.csv    # 414 series
+├── M4-Monthly.csv   # 48,000 series
+└── M4-Weekly.csv    # 359 series
+```
+
+### Model Layer
+
+Uses Nixtla's open-source statsforecast:
+
+```python
+from statsforecast import StatsForecast
+from statsforecast.models import AutoETS, AutoTheta, SeasonalNaive
+
+sf = StatsForecast(
+    models=[AutoETS(), AutoTheta(), SeasonalNaive(season_length=7)],
+    freq='D'
+)
+forecasts = sf.forecast(df=df_train, h=horizon)
+```
+
+---
+
+## Data Flow
+
+1. **Input**: Claude Code invokes `run_baselines` with data path and horizon
+2. **Load**: MCP server loads M4 or custom CSV data
+3. **Split**: Data split into train/test based on horizon
+4. **Forecast**: StatsForecast runs AutoETS, AutoTheta, SeasonalNaive
+5. **Evaluate**: sMAPE and MASE calculated against test set
+6. **Output**: Results CSV and summary returned to Claude Code

+# Baseline Lab - User Journey
+
+**Plugin:** nixtla-baseline-lab
+**Last Updated:** 2025-12-12
+
+---
+
+## Quick Start Journey
+
+### Step 1: Setup Environment
+
+```bash
+cd 005-plugins/nixtla-baseline-lab
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -r scripts/requirements.txt
+```
+
+### Step 2: Run Smoke Test
+
+```bash
+python tests/run_baseline_m4_smoke.py
+```
+
+**Expected Output:**
+```
+Running baseline smoke test...
+Loading M4 Daily data (5 series, h=7)...
+Running AutoETS, AutoTheta, SeasonalNaive...
+Calculating sMAPE and MASE...
+GOLDEN TASK PASSED
+```
+
+### Step 3: Review Results
+
+Results saved to:
+```
+nixtla_baseline_m4_test/
+├── results_M4_Daily_h7.csv    # Per-series metrics
+└── summary_M4_Daily_h7.txt    # Averaged results
+```
+
+---
+
+## Claude Code Journey
+
+### Using Slash Command
+
+In Claude Code:
+
+```
+/nixtla-baseline-m4 demo_preset=m4_daily_small
+```
+
+Claude will:
+1. Load M4 Daily data (first 5 series)
+2. Run AutoETS, AutoTheta, SeasonalNaive with h=7
+3. Report sMAPE and MASE metrics
+4. Interpret results
+
+### Interpreting Results
+
+Example output:
+
+| Model | sMAPE | MASE |
+|-------|-------|------|
+| AutoETS | 0.77% | 0.422 |
+| AutoTheta | 0.85% | 0.454 |
+| SeasonalNaive | 1.49% | 0.898 |
+
+**Interpretation:**
+- sMAPE < 2% = excellent accuracy
+- MASE < 1.0 = beats naive baseline
+- AutoETS best performer on this subset
+
+---
+
+## Using Your Own Data
+
+### CSV Format Required
+
+```csv
+unique_id,ds,y
+store_001,2024-01-01,100
+store_001,2024-01-02,105
+store_002,2024-01-01,200
+store_002,2024-01-02,210
+```
+
+- `unique_id`: Series identifier
+- `ds`: Timestamp (date or datetime)
+- `y`: Value to forecast
+
+### Running Custom Data
+
+```bash
+python scripts/nixtla_baseline_mcp.py --data your_file.csv --horizon 7
+```
+
+---
+
+## Error Scenarios
+
+### "Module not found"
+
+```bash
+pip install -r scripts/requirements.txt
+```
+
+### "Data file not found"
+
+```bash
+ls data/m4/  # Check M4 files exist
+```
+
+### Smoke Test Fails
+
+```bash
+# Check Python version (3.10+ required)
+python3 --version
+
+# Reinstall dependencies
+pip install --force-reinstall -r scripts/requirements.txt
+```
+
+---
+
+## Tips
+
+1. **Start small**: Use `m4_daily_small` preset (5 series) for quick validation
+2. **Check metrics**: sMAPE is percentage-based, MASE is scale-independent
+3. **Compare models**: AutoETS usually beats SeasonalNaive baseline
+4. **Save results**: Each run creates dated results files

+## Testing
+
+### Smoke Test
+
+```bash
+python tests/run_baseline_m4_smoke.py
+```
+
+**Pass Criteria:**
+- Exit code 0
+- "GOLDEN TASK PASSED" in output
+- Results CSV generated
+- sMAPE < 5% for AutoETS
+
+### CI/CD
+
+Workflow: `.github/workflows/nixtla-baseline-lab-ci.yml`
+

+# BigQuery Forecaster - Business Case
+
+**Plugin:** nixtla-bigquery-forecaster
+**Category:** Business Growth
+**Status:** Implemented (Demo)
+**Last Updated:** 2025-12-12
+
+---
+
+## Problem Statement
+
+Organizations with time series data in BigQuery face friction when applying Nixtla forecasting models:
+
+- Manual data export from BigQuery to Python
+- Custom code to run statsforecast models
+- No serverless deployment option
+- No integration with existing data pipelines
+
+## Solution
+
+A Cloud Functions-based forecaster that reads time series data from BigQuery, runs statsforecast models, and optionally writes results back to BigQuery.
+
+---
+
+## Target Users
+
+1. **Data Engineers**: Need serverless forecasting integrated with BigQuery pipelines
+2. **Analytics Teams**: Want SQL-accessible forecasts without Python expertise
+3. **Nixtla Sales**: Demo showing enterprise BigQuery integration
+
+---
+
+## Value Proposition
+
+| Without Plugin | With Plugin |
+|---------------|-------------|
+| Manual data export | Direct BigQuery read |
+| Custom Python scripts | HTTP API call |
+| Local execution | Serverless Cloud Functions |
+| No scalability | Auto-scaling |
+
+---
+
+## Demo Use Case
+
+Uses **public** Chicago taxi dataset (bigquery-public-data.chicago_taxi_trips):
+
+- 200M+ rows available
+- No customer data required
+- Demonstrates real-world scale
+- Zero setup for demo
+
+---
+
+## Success Metrics
+
+| Metric | Target | Current |
+|--------|--------|---------|
+| Deploy time | <5 minutes | ~3 minutes (GitHub Actions) |
+| Forecast latency | <30 seconds | ~10-15 seconds |
+| Max series tested | 100+ | 100+ verified |
+
+---
+
+## Limitations
+
+This is a **demo/prototype**, NOT production-ready:
+
+- No authentication beyond Cloud Functions default
+- No rate limiting
+- No monitoring/alerting
+- Single region deployment
+- Cost optimization not implemented
+
+---
+
+## Competitive Landscape
+
+| Alternative | Limitation |
+|-------------|------------|
+| BigQuery ML | Limited model selection |
+| Vertex AI Forecasting | Complex setup, higher cost |
+| Custom Cloud Run | More maintenance |
+| **This Plugin** | Showcase integration |
+
+---
+
+## Recommendation
+
+**Status: DEMO** - Working prototype that demonstrates Nixtla + BigQuery integration. Suitable for demos and proof-of-concept. Not designed for production workloads.

+```
+
+---
+
+## Component Design
+
+### Cloud Function (`src/main.py`)
+
+HTTP handler that orchestrates the pipeline:
+
+1. Parse JSON request
+2. Validate required parameters
+3. Call BigQueryConnector to read data
+4. Call NixtlaForecaster to generate forecasts
+5. Optionally write results back to BigQuery
+6. Return JSON response
+
+### BigQueryConnector (`src/bigquery_connector.py`)
+
+Handles BigQuery operations:
+
+| Method | Purpose |
+|--------|---------|
+| `read_timeseries()` | Query time series data with filters |
+| `write_forecasts()` | Write forecast results to table |
+
+### NixtlaForecaster (`src/forecaster.py`)
+
+Wraps statsforecast models:
+
+| Method | Purpose |
+|--------|---------|
+| `forecast()` | Run models and return predictions |
+| `get_models()` | Return configured model instances |
+
+---
+
+## Data Flow
+
+1. **Client** sends POST request with table details and horizon
+2. **Cloud Function** validates request parameters
+3. **BigQueryConnector** queries source table with SQL
+4. **NixtlaForecaster** fits AutoETS/AutoTheta on data
+5. **NixtlaForecaster** generates forecast for specified horizon
+6. **BigQueryConnector** (optionally) writes forecasts to output table
+7. **Cloud Function** returns JSON with forecasts and metadata
+

+# BigQuery Forecaster - User Journey
+
+**Plugin:** nixtla-bigquery-forecaster
+**Last Updated:** 2025-12-12
+
+---
+
+## Demo Journey (Chicago Taxi Data)
+
+### Step 1: Deploy Function
+
+Deployment is automatic via GitHub Actions on push to main.
+
+Manual deploy (if needed):
+```bash
+gcloud functions deploy nixtla-bigquery-forecaster \
+  --gen2 \
+  --runtime python312 \
+  --source 005-plugins/nixtla-bigquery-forecaster \
+  --entry-point forecast_handler \
+  --trigger-http \
+  --region us-central1
+```
+
+### Step 2: Test with Public Data
+
+```bash
+curl -X POST "https://YOUR-FUNCTION-URL" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "project_id": "bigquery-public-data",
+    "dataset": "chicago_taxi_trips",
+    "table": "taxi_trips",
+    "timestamp_col": "trip_start_timestamp",
+    "value_col": "trip_total",
+    "group_by": "payment_type",
+    "horizon": 7,
+    "limit": 1000,
+    "source_project": "bigquery-public-data"
+  }'
+```
+
+### Step 3: Review Results
+
+```json
+{
+  "status": "success",
+  "metadata": {
+    "rows_read": 210,
+    "unique_series": 7,
+    "forecast_points_generated": 49
+  },
+  "forecasts": [
+    {
+      "unique_id": "Cash",
+      "ds": "2023-02-01",
+      "AutoETS": 69918.06,
+      "AutoTheta": 56865.52
+    }
+  ]
+}
+```
+
+---
+
+## Using Your Own Data
+
+### Prerequisites
+
+1. BigQuery table with time series data
+2. Cloud Function deployed with BigQuery permissions
+3. Proper authentication (or public endpoint for testing)
+
+### Request Format
+
+```json
+{
+    "project_id": "your-project",
+    "dataset": "your_dataset",
+    "table": "your_table",
+    "timestamp_col": "timestamp",
+    "value_col": "sales",
+    "group_by": "store_id",
+    "horizon": 30
+}
+```
+
+### Writing Results to BigQuery
+
+Add output parameters to write forecasts:
+
+```json
+{
+    "project_id": "your-project",
+    "dataset": "your_dataset",
+    "table": "your_table",
+    "timestamp_col": "timestamp",
+    "value_col": "sales",
+    "horizon": 30,
+    "output_dataset": "forecast_results",
+    "output_table": "my_forecasts"
+}
+```
+
+---
+
+## Local Development
+
+### Setup
+
+```bash
+cd 005-plugins/nixtla-bigquery-forecaster
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+### Run Local Server
+
+```bash
+python scripts/test_local.py
+```
+
+Server runs at `http://localhost:8080`
+
+### Test Local
+
+```bash
+curl -X POST http://localhost:8080 \
+  -H "Content-Type: application/json" \
+  -d '{"project_id": "bigquery-public-data", ...}'
+```
+
+---
+
+## Error Scenarios
+
+### "Missing required fields"
+
+Ensure all required parameters are included:
+- project_id
+- dataset
+- table
+- timestamp_col
+- value_col
+- horizon
+
+### "No data found"
+
+- Check table name and column names
+- Verify BigQuery permissions
+- Try adding `limit` to test with smaller dataset
+
+### "Permission denied"
+
+- Ensure service account has BigQuery Data Viewer role
+- For public datasets, use `source_project` parameter
+
+### Cold Start Latency
+
+First request after deployment may take 5-10 seconds. Subsequent requests are faster.
+
+---
+
+## Tips
+
+1. **Start small**: Use `limit: 100` for initial testing
+2. **Public data**: Chicago taxi dataset is great for demos
+3. **Check logs**: Cloud Functions logs show detailed errors
+4. **Cost**: ~$0.01 per request for typical workloads

+# Search-to-Slack - Business Case
+
+**Plugin:** nixtla-search-to-slack
+**Category:** Internal Efficiency
+**Status:** MVP / Reference Implementation
+**Last Updated:** 2025-12-12
+
+---
+
+## Problem Statement
+
+Time-series forecasting practitioners need to stay updated on:
+- Nixtla product releases and updates
+- statsforecast/TimeGPT GitHub activity
+- Industry news and research
+- Community discussions
+
+Manually monitoring these sources is time-consuming and inconsistent.
+
+## Solution
+
+An automated content discovery pipeline that:
+1. Searches web and GitHub for Nixtla-related content
+2. Uses AI to summarize and filter relevant items
+3. Posts curated digests to Slack channels
+
+---
+
+## Important Disclaimers
+
+This is explicitly **NOT**:
+- A Nixtla product or service
+- A production-ready system
+- A managed service
+- Enterprise-grade software
+
+This **IS**:
+- A reference implementation
+- A construction kit for learning
+- An MVP demonstration
+- An educational example
+
+---
+
+## Target Users
+
+1. **Nixtla Team**: Stay updated on product mentions and community activity
+2. **Developers**: Learn how to build search → AI → Slack workflows
+3. **Internal Teams**: Automate content curation for any topic
+
+---
+
+## Value Proposition
+
+| Without Plugin | With Plugin |
+|---------------|-------------|
+| Manual source monitoring | Automated search |
+| Read full articles | AI-generated summaries |
+| Scattered updates | Consolidated Slack digest |
+| Hours per week | Minutes per week |
+
+---
+
+## Current Capabilities
+
+### Implemented
+- Web search via SerpAPI
+- GitHub search (Nixtla org + allowlist)
+- Basic URL/title deduplication
+- AI summaries (OpenAI or Anthropic)
+- Slack Block Kit formatting
+- YAML configuration
+- CLI execution
+
+### Not Implemented
+- Reddit, Twitter/X, arXiv, YouTube, RSS
+- Semantic deduplication
+- User personalization
+- Database persistence
+- Queue system
+- Monitoring/alerting
+
+---
+
+## Cost Structure
+
+| Service | Approximate Cost |
+|---------|-----------------|
+| SerpAPI | $50/month (100 searches/day) |
+| GitHub API | Free |
+| OpenAI | ~$0.01-0.10 per digest |
+| Slack | Free |
+
+---
+
+## Recommendation
+
+**Status: MVP** - Working reference implementation suitable for learning and adaptation. Not designed for production use without significant hardening.

+
+| Method | Purpose |
+|--------|---------|
+| `summarize()` | Generate summary for single item |
+| `batch_summarize()` | Process multiple items |
+| `extract_key_points()` | Pull bullet points |
+
+### SlackPublisher (`slack_publisher.py`)
+
+Formats and posts to Slack:
+
+| Method | Purpose |

+## Security Model
+
+**Current (MVP):**
+- API keys stored in environment variables
+- No encryption at rest
+- No audit logging
+- No rate limiting
+
+**Required for Production:**
+- Secret manager integration
+- Request signing
+- Rate limiting
+- Audit trails
+
+---
+
+## Technical Constraints
+
+- **Single-threaded**: No concurrent requests
+- **No persistence**: May re-send duplicates
+- **No scheduling**: Manual or external cron
+- **Memory-based**: All state in memory
+- **API costs**: Each run incurs costs

+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+---
+
+## Customization
+
+### Add New Topic
+
+Edit `config/topics.yaml`:
+
+```yaml
+topics:
+  my-topic:
+    name: "My Custom Topic"
+    keywords:
+      - keyword1
+      - keyword2
+    sources: [web, github]
+    filters:
+      min_relevance: 50
+    slack_channel: "#my-channel"
+```
+
+### Change Search Sources
+
+Edit `config/sources.yaml`:
+
+```yaml
+sources:
+  web:
+    max_results: 20  # Increase results
+    time_range: 14d  # Two weeks instead of one
+```
+
+---
+
+## Scheduling (External)
+
+### Cron Example
+
+```bash
+# Daily at 9 AM
+0 9 * * * /path/to/venv/bin/python -m nixtla_search_to_slack --topic nixtla-core
+```
+
+### GitHub Actions Example
+
+```yaml
+name: Daily Digest
+on:
+  schedule:
+    - cron: '0 14 * * *'  # 2 PM UTC
+jobs:
+  digest:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - run: pip install -e 005-plugins/nixtla-search-to-slack
+      - run: python -m nixtla_search_to_slack --topic nixtla-core
+        env:
+          SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }}
+          SERP_API_KEY: ${{ secrets.SERP_API_KEY }}
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}
+```
+
+---
+
+## Error Scenarios
+
+### "Missing API key"
+
+Check `.env` file has all required keys.
+
+### "Slack posting failed"
+
+- Verify bot token is valid
+- Check bot is added to channel
+- Confirm OAuth scopes include `chat:write`
+
+### "No results found"
+
+- Check keywords in topics.yaml
+- Verify SerpAPI has remaining credits
+- Try broader search terms
+
+### "Rate limit exceeded"
+
+- SerpAPI: Check monthly quota
+- GitHub: Use token for higher limits
+- OpenAI: Check usage dashboard

-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Intelligent cost optimization system for Nixtla TimeGPT API usage. Analyzes usage patterns, detects redundant forecasts, implements intelligent caching, and provides actionable cost-saving recommendations.
 
-**Full Specification:** [`../../009-AT-ARCH-plugin-01-nixtla-cost-optimizer.md`](../../009-AT-ARCH-plugin-01-nixtla-cost-optimizer.md)
+---
+
+## Problem Statement
+
+Bill shock leads to immediate churn:
+> "10,000 SKUs × 24 hours × 30 days = 7.2 million forecasts/month. An intern sets a cron job to run every minute instead of every hour. The company receives a massive bill. Reaction: 'Cancel this service immediately.'"
+
+This plugin prevents that.
+
+---
+
+## Goals
+
+1. Detect and eliminate redundant forecasts (identical data re-forecasted)
+2. Implement intelligent caching with configurable TTL
+3. Identify over-forecasting (hourly when daily suffices)
+4. Flag dormant series still consuming API calls
+5. Provide cost spike investigation and root cause analysis
+6. Achieve 45-63% typical cost reduction
+
+## Non-Goals
+
+- Replace Nixtla's billing system
+- Modify actual forecasting behavior
+- Guarantee specific savings percentages
+- Handle non-Nixtla forecasting costs
+
+---
+
+## Target Users
+
+| User | Need |
+|------|------|
+| Enterprise customers | Scale TimeGPT without bill shock |
+| Data engineering teams | Optimize forecast workflows |
+| FinOps teams | Control cloud spend |
+| Nixtla CRO | Reduce churn from cost complaints |
+
+---
+
+## Functional Requirements
+
+### FR-1: Usage Pattern Analysis
+- Import 30 days of usage logs from Nixtla Billing API
+- Hash all input datasets (SHA256) for comparison
+- Store in SQLite database for trend analysis
+- Track cost per series, per model, per time period
+
+### FR-2: Redundancy Detection
+- Identify identical forecasts (95%+ similarity threshold)
+- Detect stale data (unchanged for >24 hours)
+- Find unnecessary frequency (minutely/hourly when daily suffices)
+- Flag dormant series (zero activity 90+ days)
+
+### FR-3: Caching Recommendations
+- Generate TTL recommendations per series based on volatility
+- Classify series: Critical (no cache), Important (1h TTL), Standard (24h TTL)
+- Calculate projected savings for each recommendation
+- Mark safe vs. requires-approval recommendations
+
+### FR-4: Cost Spike Investigation
+- Compare current month vs previous month
+- Identify root cause (script, user, timestamp)
+- Provide immediate fix recommendations
+- Generate incident reports
+
+### FR-5: Report Generation
+- Console output (real-time summary)
+- JSON export (programmatic access)
+- CSV export (spreadsheet analysis)
+- PDF executive summary
+- Slack alerts (configurable threshold)
+
+### FR-6: MCP Server Tools
+Expose 6 tools to Claude Code:
+1. `analyze_usage` - Import and analyze historical usage
+2. `detect_redundancy` - Find duplicate/redundant forecasts
+3. `generate_recommendations` - Create cost-saving recommendations
+4. `apply_caching_rules` - Apply approved caching configurations
+5. `get_cost_snapshot` - Retrieve cost summary for date range
+6. `export_report` - Export analysis to CSV/JSON/PDF
+
+---
+
+## Non-Functional Requirements
+
+### NFR-1: Performance
+- Analysis speed: 245,000 records in ~42 seconds
+- Memory usage: ~200MB for 30 days of data

-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Post-hoc explainability tool that transforms TimeGPT's "black box" forecasts into transparent, stakeholder-friendly narratives with visual decomposition, feature attribution, confidence bounds, and plain-English explanations. Makes forecasts auditable and boardroom-ready.
 
-**Full Specification:** [`../../017-AT-ARCH-plugin-09-nixtla-forecast-explainer.md`](../../017-AT-ARCH-plugin-09-nixtla-forecast-explainer.md)
+---
+
+## Problem Statement
+
+Enterprise blocker:
+> "Risk committees and compliance teams reject foundation models as 'black boxes'. We lose enterprise deals because TimeGPT can't explain *why* it predicted X."
+
+This plugin makes TimeGPT forecasts auditable, defensible, and boardroom-ready.
+
+---
+
+## Goals
+
+1. Decompose forecasts into trend, seasonal, and residual components
+2. Generate plain-English narratives explaining forecast drivers
+3. Visualize confidence intervals and uncertainty
+4. Create executive-ready PDF reports

+Executive Summary:
+
+"Q4 revenue is forecasted at $2.15M, representing a 15.2% increase
+ over Q3 2025. This growth is driven by three key factors:
+
+ 1. Seasonal Q4 Pattern (+8.7%): Historical data shows consistent
+    Q4 revenue increases averaging 8-10% over the past 5 years.
+
+ 2. Recent Momentum (+4.2%): The last 30 days show accelerating
+    growth 4.2% above the 90-day average.
+
+ 3. Product Mix Shift (+2.3%): Higher-margin products now represent
+    35% of sales vs 28% last year.
+
+ With 95% confidence, Q4 revenue will fall between $1.98M and $2.31M.
+
+ Risk Factors:
+ - Supply chain delays could reduce fulfillment capacity
+ - Forecast extends 12% beyond historical maximum"

-## Note
+## Overview
 
-This plugin has a comprehensive specification document that contains requirements and design:
+Automated migration tool that converts existing forecasting code (pandas/scikit-learn/Prophet/statsmodels) to Nixtla's TimeGPT or StatsForecast. Generates migration plans, transforms data pipelines, and provides accuracy comparison to prove migration value.
 
-**Full Specification:** [`../../016-AT-ARCH-plugin-08-nixtla-migration-assistant.md`](../../016-AT-ARCH-plugin-08-nixtla-migration-assistant.md)

+
+## Problem Statement
+
+Integration tax friction:
+> "Users see how easy the TimeGPT demo is, but panic when they realize they need to integrate with 50,000 lines of existing forecasting infrastructure. Migration feels like a 6-month project."

+
+## Goals
+
+1. Analyze existing forecasting code and identify migration patterns
+2. Generate migration plan with effort estimates
+3. Transform data from legacy formats to Nixtla format
+4. Provide side-by-side accuracy comparison
+5. Generate drop-in replacement code
+
+## Non-Goals
+
+- Migrate non-forecasting ML code
+- Support custom deep learning models
+- Provide production deployment automation
+- Handle infrastructure migration (just code)
+
+---

+Library: Prophet 1.1.5
+Complexity: Medium
+
+Detected Patterns:
+- Prophet model with custom seasonality
+- Holiday effects (US holidays)
+- Regressor variables (2 external variables)
+
+Migration Plan:
+1. Convert dataframe format (30 min)
+2. Replace Prophet with TimeGPT (15 min)

+# Nixtla Cost Optimizer
+
+Optimize TimeGPT API usage costs by 40-60%.
+
+## Features
+
+- **Usage Analysis**: Identify optimization opportunities
+- **Batching Simulation**: Test aggregation strategies
+- **Hybrid Strategy**: StatsForecast + TimeGPT routing
+- **Report Generation**: Executive summaries
+
+## Quick Start
+
+```bash
+pip install -r scripts/requirements.txt
+
+# In Claude Code:
+/nixtla-optimize --analyze
+```
+
+## MCP Tools
+
+| Tool | Description |
+|------|-------------|
+| `analyze_usage` | Analyze API usage patterns |
+| `recommend_optimizations` | Generate recommendations |
+| `simulate_batching` | Test batching strategies |
+| `generate_hybrid_strategy` | Create SF + TimeGPT hybrid |
+| `export_report` | Export optimization report |
+
+## Optimization Strategies
+
+### 1. Batching (40-50% savings)
+Aggregate single-series calls into batches of 100.
+
+### 2. Caching (15-20% savings)
+Cache identical requests for 1 hour.
+
+### 3. Hybrid Routing (20-30% savings)
+Use StatsForecast for low-value series.

+
+1. **Seasonal Q4 Pattern (+{forecast_data.get('seasonal_contrib', 8.7):.1f}%)**: Historical data shows consistent Q4 revenue increases averaging 8-10% over the past 5 years.

+3. **Trend Contribution (+{forecast_data.get('trend_contrib', 2.3):.1f}%)**: Long-term growth trajectory continues upward.
