# Seahaven Slack Bot

Internal Slack DM assistant for Sea Haven Industries, powered by AWS Bedrock. Employees can ask questions about vendors, company policies, SOPs, and SA8000 compliance via direct message.

## Architecture

```
Slack DM
   │
   ▼
API Gateway (bot.seahaven.com)
   │
   ▼
slack-webhook Lambda          ← verifies Slack signature, returns 200 immediately
   │ (async invoke)
   ▼
slack-processor Lambda        ← calls Bedrock Agent, logs to DynamoDB, posts reply
   │
   ▼
Bedrock Agent (Claude Sonnet 4.5)
   ├── Knowledge Base (AOSS + S3)    ← SA8000 docs, SOPs, employee handbook
   ├── QBO_Lookup action group       ← QuickBooks vendor search
   └── Google_Maps_Lookup action group ← fallback vendor search
```

### Vendor Query Priority
1. **QBO** — existing vetted vendors in QuickBooks Online
2. **Knowledge Base** — approved vendor lists in internal docs
3. **Google Maps** — fallback for net-new vendor discovery

## Stack

| Resource | Details |
|---|---|
| AWS Account | 328440206208, us-east-1 |
| CDK | TypeScript, v2 |
| LLM | Claude Sonnet 4.5 (`anthropic.claude-sonnet-4-5-20250929-v1:0`) |
| Embeddings | Amazon Titan Embed Text V2 (1024 dimensions) |
| Vector Store | OpenSearch Serverless (VECTORSEARCH) |
| Conversation Log | DynamoDB `seahaven-conversations` (90-day TTL) |
| Webhook URL | `https://bot.seahaven.com/slack/events` |

## Prerequisites

- Node.js 22+
- AWS CDK (`npm install -g aws-cdk`)
- Docker Desktop (required by `@cdklabs/generative-ai-cdk-constructs` for Lambda bundling)
- AWS credentials configured locally

## Secrets Manager

These three secrets must exist before deploying. Create them via the AWS Console or CLI:

| Secret Name | Structure |
|---|---|
| `seahaven/slack/credentials` | `{ "botToken": "xoxb-...", "signingSecret": "..." }` |
| `seahaven/qbo/oauth` | `{ "clientId": "", "clientSecret": "", "refreshToken": "", "realmId": "" }` |
| `seahaven/google/maps-api-key` | `{ "apiKey": "" }` |

## Deployment

```bash
npm install
npx cdk bootstrap aws://328440206208/us-east-1   # first time only
npx cdk deploy
```

The deploy takes ~15 minutes on first run. The AOSS collection and vector index creation are the slow steps — both handled automatically.

Stack outputs after deploy:
- `KBDocsBucketName` — S3 bucket to upload knowledge base documents
- `AgentId` — Bedrock Agent ID
- `SlackWebhookUrl` — URL to register in Slack app settings

## Post-Deployment Setup

### 1. Upload knowledge base documents

Upload SA8000 compliance docs, SOPs, and the employee handbook to the S3 bucket printed in stack outputs. Supported formats: PDF, DOCX, TXT, HTML, CSV, XLSX.

```bash
aws s3 cp ./your-docs/ s3://<KBDocsBucketName>/ --recursive
```

### 2. Trigger KB sync

```bash
aws bedrock-agent start-ingestion-job \
  --knowledge-base-id <AgentId from outputs> \
  --data-source-id <DataSourceId> \
  --region us-east-1
```

Or trigger from the Bedrock console: **Knowledge Bases → seahaven-kb → Sync**.

### 3. Configure Slack app

In the [Slack API dashboard](https://api.slack.com/apps):

1. **Event Subscriptions** → enable → set Request URL to `https://bot.seahaven.com/slack/events`
2. Subscribe to bot event: `message.im`
3. **OAuth & Permissions** → Bot Token Scopes: `chat:write`, `im:history`
4. **App Home** → Messages Tab → enable, allow users to send messages
5. Reinstall to workspace if prompted

## Known Maintenance Items

- **QBO refresh token** expires after 100 days of inactivity. Rotate via the [Intuit OAuth Playground](https://developer.intuit.com/app/developer/playground) and update the `seahaven/qbo/oauth` secret.
- **KB sync** must be triggered manually after uploading new documents. Consider adding a scheduled EventBridge rule for automatic nightly syncs.
