About

Hey there, I built SPCMP and CAGM. Two infrastructure protocols which address two of the core problems in computation. SPCMP- A digital vault that sorts decimal numbers perfectly across different computers and locks them so they can never be altered or tampered with. CAGM- A digital mold for AI that forces different computers to train and run the exact same model, producing identical answers every single time.

Samayuktam SPCMP - Tamper-evident proofs for compressed data.

A checksum says the bytes match, and anyone who rewrites the file can recompute it. SPCMP commits the decoded data to a Merkle root and signs the file with Ed25519, so you can prove it hasn’t changed since it was sealed. Pricing and tests are public.

What one day of launching a dev security tool taught me

Today I launched Agentmetry, an open-source tool I've been building alone: it records what AI coding agents like Claude Code, Cursor and Codex actually do on your machine (every command, file read and tool call) into a tamper-evident local log.

A few things I didn't expect, which might be useful to anyone building developer tools:

1. The first real feature request wasn't about security. A developer asked to see time and token usage broken down by task and tool, because they'd found by hand that one browser tool was burning most of their time and tokens. Same data, completely different value. I'd been pitching the wrong benefit to half my audience.

2. Saying what the tool can't do helped more than the features. It only sees agents whose hooks are installed, and it can't see cloud agents at all. Every time I said that up front, the conversation got more serious, not less.
