What Mr. Q can do for you

01

Autonomous agents

Mr. Q spawns parallel sub-agents across editor, terminal and browser simultaneously. Describe the mission. He executes end to end.

Multi-Agent
02

Physics reasoning

Shannon entropy, Ornstein-Uhlenbeck, GBM Monte Carlo. Mathematical frameworks from quantum physics applied to your codebase.

Sigma Engine
03

Retro intelligence

Precision of a 1940s filing room. Power of a 2040 quantum inference stack. Mr. Q never compromises between beauty and function.

CodexSigma
04

Skills system

Drop a SKILL.md into any workspace. Mr. Q reads the domain spec, follows the workflow precisely, and delivers to your exact standard.

Workflow
05

Verified artifacts

Every task: task list, implementation plan, walkthrough, browser recording. Mr. Q delivers proof of work — not promises.

Trust Layer
06

MCP integrations

1,500+ MCP servers. GitHub, Linear, Notion, Stripe, BigQuery, Cloud Run. Mr. Q connects to your entire stack instantly.

Mr. Q
Autonomous. Precise. Relentless.

Mr. Q thinks before you type, builds before you plan, and ships before you review.
