destroy-project

name: destroy-project description: Tears down all AWS infrastructure and releases Daily.co phone numbers. Guides through Daily phone number release, pinless dial-in cleanup, CDK stack destruction, and output file cleanup. Use when done experimenting, cleaning up resources, or shutting down the deployment.

Destroy Project — Full Teardown

You are guiding the user through a complete teardown of the voice agent deployment. This includes releasing Daily.co phone numbers (which CDK cannot manage) and destroying all AWS CloudFormation stacks.

When This Skill Activates

• User says "destroy", "tear down", "clean up", "delete everything", "remove deployment"
• User asks about stopping charges or cleaning up resources
• User is done experimenting and wants to shut down

What To Do

Phase 1: Confirm Intent

This is destructive and irreversible. Make sure the user understands:

• All AWS resources (VPC, ECS, Lambda, SageMaker endpoints, Secrets Manager, DynamoDB tables) will be deleted
• Daily.co phone numbers will be released and cannot be recovered
• The .env files with secrets will remain on disk but the AWS-side secrets will be gone

Ask: "This will destroy all AWS resources and release your Daily.co phone number. Are you sure you want to proceed?"

Phase 2: Release Daily.co Phone Number

This step must happen before CDK destroy, because the Daily API key is stored in Secrets Manager which CDK will delete.

1. Load Daily API key and phone number from .env:

   ENV_FILE="backend/voice-agent/.env"
   if [ -f "$ENV_FILE" ]; then
     set -a && source "$ENV_FILE" && set +a
   fi
   

2. Check if a Daily API key exists:

   • If DAILY_API_KEY is empty: warn that you cannot release phone numbers automatically. Tell user to release manually at dashboard.daily.co under Phone Numbers, then skip to Phase 3.

3. List purchased phone numbers:

   AUTH_HEADER="Authorization: Bearer $DAILY_API_KEY"
   curl -s -H "$AUTH_HEADER" 'https://api.daily.co/v1/purchased-phone-numbers' | python3 -c "
   import json, sys
   data = json.load(sys.stdin)
   numbers = data.get('data', [])
   if not numbers:
       print('No purchased phone numbers found.')
   else:
       print(f'Found {len(numbers)} purchased number(s):')
       for n in numbers:
           print(f'  {n[\"number\"]} (id: {n[\"id\"]})')
   "
   

4. Show the numbers and get confirmation before releasing. Warn: "A number cannot be released within 14 days of purchase. If you purchased recently, you may get an error."

5. Release each phone number:

   curl -s -X DELETE -H "$AUTH_HEADER" "https://api.daily.co/v1/release-phone-number/$PHONE_ID"
   

   Check for errors in the response. A 14-day restriction error is non-fatal -- inform the user the number will need to be released later from the Daily dashboard.

6. Remove pinless dial-in configuration from the domain:

   curl -s -H "$AUTH_HEADER" -H 'Content-Type: application/json' -d '{"properties": {"pinless_dialin": []}}' 'https://api.daily.co/v1/'
   

   This clears the webhook configuration so Daily stops sending requests to the now-deleted API Gateway.

Phase 3: Destroy AWS Infrastructure

cd infrastructure && ./deploy.sh destroy

This runs npx cdk destroy --all --force and removes all 10 CDK stacks:

• VoiceAgentNetwork (VPC, NAT, security groups)
• VoiceAgentStorage (Secrets Manager, KMS)
• VoiceAgentSageMaker (GPU endpoints, if deployed)
• VoiceAgentKnowledgeBase (Bedrock KB, S3 bucket)
• VoiceAgentEcs (Fargate cluster, NLB, CloudWatch dashboard)
• VoiceAgentBotRunner (Lambda, API Gateway)
• VoiceAgentCRM (DynamoDB tables)
• VoiceAgentKbAgent (KB capability agent)
• VoiceAgentCrmAgent (CRM capability agent)

Wait for the destroy to complete. This typically takes 5-10 minutes. SageMaker endpoints may take longer.

If destroy fails partway through:

• "Stack is in DELETE_FAILED state" -- Some resources may have deletion protection or dependencies. Re-run npx cdk destroy --all --force or delete the stuck stack manually in CloudFormation console.
• "Role does not exist" -- The IAM role was already deleted. This usually resolves on retry.

Phase 4: Clean Up Local Files

Remove deployment output files:

cd infrastructure
rm -f outputs.json outputs-*.json cdk.out

Optionally remind the user:

• The .env files in backend/voice-agent/ and infrastructure/ still contain API keys on disk. These are gitignored but the user may want to clear them.
• The CDK bootstrap stack (CDKToolkit) is NOT deleted by cdk destroy --all. It can be reused for future deployments or removed manually via CloudFormation if the account is being decommissioned.

Phase 5: Report

Show final status:

Teardown Complete:
[check/x] Daily phone number(s) released
[check/x] Pinless dial-in webhook cleared
[check/x] AWS infrastructure destroyed (all CDK stacks)
[check/x] Local output files cleaned up

Remaining items (manual):
- CDK bootstrap stack (CDKToolkit) still exists in the account
- Local .env files still contain API keys (gitignored)
- Daily.co account still active (no ongoing charges without active resources)

If any phone numbers could not be released due to the 14-day restriction, include a reminder:

Action required:
- Phone number [number] cannot be released until [date].
  Release it manually at https://dashboard.daily.co or re-run this
  cleanup after the 14-day hold period.
