Brownfield Onboarder

@anton-abyzov/specweave-specweave-brownfield-onboarder

Intelligently onboards brownfield projects by merging existing CLAUDE.md backups into SpecWeave structure. Extracts project-specific knowledge, domain context, team conventions, and technical details from backup CLAUDE.md files, then distributes content to appropriate SpecWeave folders without bloating CLAUDE.md. Activates for: merge docs, merge claude, onboard brownfield, import existing docs, claude backup, specweave merge-docs.
