What it is
What it does
Rashomon is an open-source execution recorder for AI coding agents that keeps its own record of events and compares it against the agent’s account.
Problem
It addresses the issue of agent transcripts not being ground truth and provides a reliable record of what occurred during execution.
Who pays
individuals or teams building AI coding agents
Weaknesses
There are still edge cases around cwd, git state, test-selection arguments, generated files, retries, and parallel execution.
What could be built instead
Opportunity
Gather feedback from users to enhance the capture and correlation of execution signals.
Vertical niche
Yes, it can be considered a vertical SaaS for AI development tools.
MVP
The minimum viable product is a CLI tool that records execution events and generates reports.
Differentiation
It differentiates itself by providing a timeline of events and insights rather than just raw outputs.
AI opportunity
AI can create real value by providing reliable execution records that help in debugging and improving agent performance.
