Background

We at 99acres are building an AI-powered chatbot to help buyers and tenants navigate their home search through specialised agents like locality finder, price insights, project discovery, property details, comparison tools, etc.

To support continuous iteration, we’re creating an in-house agent builder that enables product and design teams to create, edit, test, and publish agents independently, allowing faster experimentation and evolution of the chatbot experience without engineering dependency.

In process

Prototype

Core capabilities we are building

Create a new agent from scratch

  1. Refine what an agent says - edit system prompts

  2. Control what capabilities an agent has - assign / remove tools

  3. Control what users see while the agent works - SSE event labels

  4. Test whether changes work before going live - playground

  5. Save a stable version of an agent and roll back if needed - versioning

End of summary

Project is currently mid-process. Happy to share detailed process offline:

  • Figuring out usability & workflows by studying other agent building platforms

  • Simply approaching the UI by utilising Shadcn components

  • Collaborating on this project as two designers, vibecoding separate pages

  • How using Claude helped me fast-track this project while I was in between other P0 tasks

  • How we plan to give a handoff to the tech & product team
