ThumbGate

Pre-action checks that stop AI agents from repeating mistakes

ThumbGate sits in front of coding-agent tool calls and blocks risky repeats before they run. It turns thumbs-up and thumbs-down feedback into reusable rules, with local use for individuals and paid options for dashboards, sync, and team visibility.

What It Is

ThumbGate is an agent-governance and safety layer for AI coding workflows. It is built for developers, solo operators, consultancies, and platform teams using tools like Claude Code, Cursor, Codex, Gemini CLI, and MCP-compatible tools. Rather than...

What To Know

ThumbGate is most useful when the same agent mistake keeps happening and you want a guardrail at execution time, not just a better chat UI. The content emphasizes repeated-failure blocking, audit trails, and prevention rules created from feedback....

Agent Infrastructure

Memora is a state layer for federated learning, multi-agent systems, and edge swarms that aims to keep shared data byte-identical across heterogeneous nodes. It focuses on signed writes, deterministic aggregation, and Byzantine-robust consensus rather than general-purpose agent execution.
