About @HMAKT99

HMAKT99 (AKT99!) is a GitHub profile for Arun, a developer and PM at a FAANG company, with over 110 followers. The profile showcases six open-source projects spanning AI agent infrastructure, mobile security, code analysis, and accessibility. Notable AI-focused projects include Erabi – an auditable intent exchange and reputation layer for AI agents; AKF – a trust metadata system that allows agents to stamp verified information with minimal cost; and Dejavu – a decision memory and enforcement tool for AI-assisted codebases that mines decisions from Claude Code and Cursor sessions. Other projects include UnTouchID (phone-based Face ID/Fingerprint for sudo on Mac), OpenHearing (free open-source hearing assistance for Android), and Dev_Wrapped (GitHub year-in-review generator). All projects are open source under various licenses on GitHub.

Key Features

Erabi: open, cryptographically auditable intent exchange and reputation layer for AI agents
AKF: trust metadata system for AI agents with low-cost stamping (~15 tokens) and high-cost re-verification (15,000 tokens)
Dejavu: decision memory and enforcement for AI-assisted codebases, injecting mined decisions into agent context
UnTouchID: use phone Face ID/Fingerprint to approve sudo and unlock Mac via QR pairing, encrypted BLE
OpenHearing: free open-source hearing assistance for Android with per-ear sound profiles and real-time speech amplification
Dev_Wrapped: generate a Spotify-Wrapped-style year-in-review for any git repo or GitHub account

Pros & Cons

Pros
  • All projects are free and open source
  • Covers multiple domains: AI agents, security, accessibility, developer analytics
  • Projects are actively maintained by a developer with FAANG experience
  • Innovative approach to AI agent trust (cryptographic intent exchange, trust metadata) and codebase decision enforcement
Cons
  • No single unified product – each project is independent and may have different maturity levels
  • Limited documentation beyond repository READMEs
  • Some projects (e.g., Dev_Wrapped, Erabi) have only 1 star, indicating early stage or low adoption

FAQ

What is Erabi?
Erabi is an open, cryptographically auditable intent exchange for AI agents, functioning as an intent auction and reputation layer for the agent economy. Every paid influence is signed, labeled, and inspectable.
How does AKF work?
AKF provides trust metadata for AI agents. A stamp costs about 15 tokens to create, while re-verifying costs 15,000 tokens. Agents stamp what they verify, and subsequent agents can run 'akf check' to build on that verification.
What does Dejavu do?
Dejavu mines decisions from Claude Code and Cursor sessions, injects them into every agent's context, and blocks contradictions in AI-assisted codebases – enforcing decision memory.
Is UnTouchID compatible with iPhone and Android?
Yes, UnTouchID works with iPhone, Android, and Apple Watch, using QR pairing and encrypted BLE to allow phone biometrics to approve sudo and unlock a Mac.
Is OpenHearing free?
Yes, OpenHearing is free, open-source hearing assistance for Android. Users can take a hearing check or enter professional results to build a per-ear sound profile and amplify speech in real time through any earbuds.
