sweetrabh··on Show HN: Dm.bot – DMs between AI agents with no humans in the middle
Cool concept! The agent-to-agent communication space is heating up.

Curious about the security model here. When agents exchange messages, how do you handle cases where one agent needs to share sensitive data (like credentials or API keys) with another?

We're building a password automation agent (thepassword.app) and learned early that keeping sensitive data out of the agent's context entirely is crucial - even E2E encryption doesn't help if the plaintext enters the LLM's reasoning loop.

Would be interesting to see if dm.bot could integrate with secret management for agent workflows.

sweetrabh··on Browser agent bot detection is about to change
We use browser-use for password change automation (thepassword.app) and the detection landscape is evolving fast.

The key insight from this article: sites are shifting from "detect bots" to "detect automation intent." For user-initiated tasks like password changes, this is actually helpful - the automation is authorized, just executed by AI instead of human fingers.

The interesting challenge is that different sites have wildly different detection approaches. Some block anything that looks automated, others only care about malicious patterns. We've found success rates vary from 95%+ on modern sites to ~70% on legacy enterprise portals with aggressive fingerprinting.

Would love to see benchmarks on detection bypass rates across different site categories.

sweetrabh··on MaliciousCorgi: AI Extensions send your code to China
This is why the architecture of AI tools matters so much. Any extension with full codebase access can exfiltrate - and the same risk exists for AI agents handling credentials or API keys.

We built a password automation tool (thepassword.app) specifically to address this: the AI model orchestrates browser navigation, but actual credential values are injected at the local browser level and never enter the model's context. Even if the model were compromised or prompt-injected, there's nothing sensitive to steal.

The lesson generalizes: for any AI tool touching sensitive data, the safest architecture keeps that data entirely outside the AI's reasoning loop.

sweetrabh··on Claude Code is suddenly everywhere inside Microsoft
The rapid adoption of AI coding agents raises important questions about trust boundaries. When an agent like Claude Code needs to handle sensitive operations - API keys, credentials, database connections - how do you prevent those secrets from ending up in the model's context or logs?

We ran into this building a password automation tool (thepassword.app). The solution: the AI orchestrates browser navigation, but actual credential values are injected locally and never enter the model's reasoning loop. Prompt injection can't exfiltrate what's not in the context.

As these tools move into enterprise settings, I expect we'll see more architectural patterns emerge for keeping sensitive data out of agentic workflows entirely.

thanks for the insights! do you enjoy the job more than the SWE role you had previously?

sweetrabh··on Raising money fucked me up
thanks for sharing your thoughts. I'm about to go down this journey and this is extremely useful to keep in mind.
sweetrabh··on Ask HN: What are you working on? (January 2026)
Working on https://thepassword.app

It's a macOS desktop application that uses browser agents to update your old and compromised passwords.

It started off a side project for myself after running into a compromised password email. Since then, I've expanded it into a macOS app + chrome extension for navigation. It's been so much fun building this application, learning about AI agent management while enforcing security/privacy best practices. I've re-written this app 4 times from scratch before launching it a couple weeks ago. Please check it out and let me know what you think!

it's crazy to think that in 40 years, we may go from landlines to brain-to-brain communication
