Exec Aide (Lauren)

Personal AI executive assistant for Adam Moussa. Monitors Gmail inbox, classifies emails by urgency using Claude Haiku (Bedrock), delivers Slack alerts and daily digests, manages tasks and reminders, integrates with Google Calendar, and supports two-way conversation via Slack DM and @mentions in channels.

Architecture

EventBridge (15 min) → fetch-classify Lambda → Gmail API → Bedrock Haiku → DynamoDB + Slack DM
EventBridge Scheduler (5 PM ET M-F) → daily-digest Lambda → DynamoDB + Gmail API → Slack DM
Fargate (Socket Mode) → Slack listener → conversation Lambda → Bedrock Sonnet + tools → Slack reply
EventBridge Scheduler (one-shot) → reminder Lambda → Slack DM

Stack: CDK (TypeScript), stack name exec-aide, region us-east-1

CI/CD: CodePipeline + CodeBuild — auto-deploys on push to main. Pipeline stack: exec-aide-pipeline.

Services

• exec-aide-fetch-classify (Lambda): Polls Gmail via History API every 15 minutes, classifies each new message via Bedrock Haiku, filters out marketing, sends immediate Slack DM for HIGH priority, tracks thread state for unanswered detection.
• exec-aide-daily-digest (Lambda): Runs weekdays at 5 PM ET (DST-aware). Summarizes high-priority items, bypassed work orders, and unanswered threads older than 24h.
• exec-aide-conversation (Lambda): Bedrock Sonnet-powered conversational assistant. Handles multi-turn conversations with tool use for inbox queries, Gmail search, coordination threads, calendar management, tasks, reminders, and on-demand digest triggers. Channel-aware: declines private info in public channels. Invoked asynchronously by the listener.
• exec-aide-reminder (Lambda): Receives one-shot EventBridge Scheduler invocations and sends reminder text as a Slack DM to Adam.
• exec-aide-listener (Fargate): Socket Mode Slack bot. Handles DMs (with "Thinking..." placeholder UX), @mentions in channels (flat or threaded replies), and coordination thread routing. Runs in a dedicated VPC (10.30.0.0/16) on ARM64.
• DynamoDB exec-aide: Single-table design (MSG#, THD#, META#, CONV#, COORD#, TASK# prefixes). GSI by-date for daily digest queries. 90-day TTL (7-day for COORD).

CDK Constructs

• lib/constructs/email-pipeline.ts — DynamoDB table, all four Lambda functions (fetch-classify, daily-digest, conversation, reminder), EventBridge schedules
• lib/constructs/socket-mode.ts — VPC, ECS cluster, Fargate service, ECR repo (image built automatically via ContainerImage.fromAsset())

Classification Rules

Category	Trigger
HIGH	VIP sender, urgency keywords, escalation language, financial/legal matters
NORMAL	Standard business correspondence
LOW	FYI-only, calendar confirmations, informational notifications
MARKETING	Newsletters, promotions, bulk mailings, cold outreach (filtered out)
Bypassed WO	Email to Adam without work-orders@ in TO/CC
Unanswered	Thread where Adam hasn't replied in 24h+

Prerequisites

• AWS CDK CLI (npm install -g aws-cdk)

# Authorize as adam@seahavenind.com (grants gmail.readonly + calendar scopes)
# Copy output JSON to Secrets Manager

2. Secrets Manager

Secret	Contents
exec-aide/gmail-oauth	{ client_id, client_secret, refresh_token, access_token, token_expiry }
exec-aide/slack-credentials	{ botToken, signingSecret, appToken }

3. SSM Parameters

Parameter	Value

Deploy

Pushes to main trigger the CI/CD pipeline automatically. For manual deployment:

npm install
cdk deploy

Manual Testing

aws lambda invoke --function-name exec-aide-fetch-classify /dev/stdout
aws lambda invoke --function-name exec-aide-daily-digest /dev/stdout

Or DM the Exec Aide bot in Slack to test the conversational assistant.

Updating VIP List

Edit the SSM parameters — changes take effect on the next Lambda cold start:

aws ssm put-parameter --name /exec-aide/vip-senders --value '["new@example.com"]' --type String --overwrite
