About Causari

The first content-addressable ledger for AI agents. Every prompt, model, read, write and reasoning becomes an immutable causal event, captured at the wire, no agent cooperation required. Trace, bisect, revert and explain every line your agents wrote. re audit reads plain git history, detects AI-authored commits from verifiable metadata ( Co-Authored-By trailers, bot authors, aider markers) and measures how many of those lines are still alive at HEAD. Every number carries its evidence class: VERIFIED (explicit metadata) is never mixed with PROBABLE (heuristic).

About Pluginboard

Pluginboard is a searchable catalog for people extending AI agents. It lists plugins, skills, MCP servers and agents that work in tools like Claude Code, ChatGPT, Cursor, Codex and Gemini CLI, and each listing passes a security scan and includes setup instructions for every supported agent. Community recipes show how several listings combine to finish a task, such as writing a PRD from customer feedback. Browsing is free. Makers can list a project at no cost or claim one already created from their repository. Optional paid plans for makers, Premium at 9.97 USD and Max at 49.97 USD per month, add badges, custom buttons, insights and sponsored placement.
