Sample checks: reopening the URLs.

How to use it

1
Download the agentDownload the verificateur-sources.md file from this page.
2
Understand its roleThis agent audits other agents' work: it reads their JSON files (market, competition, customs, prospects) and a schema of sourced facts. It is designed to fit into an agent chain driven by an orchestrator; adapt folder paths to your setup.
3
Install in Claude CodePlace the file in your project's .claude/agents/ folder (or ~/.claude/agents/ for all your projects), then restart Claude Code.
4
Run a checkAsk for example: "Check the sources of the files from run 2026-10". The agent returns a JSON decisions file (verified, to verify, rejected) and a summary: rejection rate per agent, agents to rerun above 20%, the three most serious issues.
