Exec Aide

Personal AI agent that monitors Adam Moussa's Gmail inbox, classifies emails by urgency using Claude Haiku (Bedrock), and delivers Slack alerts and daily digests via a dedicated Slack app.

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 → two-way conversation with Adam

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

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-listener (Fargate): Socket Mode Slack bot for two-way conversation. Runs in a dedicated VPC (10.30.0.0/16) on ARM64.
• DynamoDB exec-aide: Single-table design (MSG#, THD#, META# prefixes). GSI by-date for daily digest queries. 90-day TTL.

CDK Constructs

• lib/constructs/email-pipeline.ts — DynamoDB table, both Lambda functions, 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+

Manual Testing

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

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
