Watch out for

OpenAI token limits may truncate long proposals so you should set a maximum word count or chunk the generation process.
Google Slides API requires precise slide ID mapping so verify your template structure before automating the content insertion.
Stripe webhooks can fail silently if the client's email is invalid so add validation logic before creating the payment link.
Gmail sending limits can block bulk operations so implement a small delay between emails to avoid rate limiting errors.
