Scored across 8 tools
Each tool targets a distinct OSINT task (general search, source listing, DNS brute, email search, host search, Shodan integration, full recon, status check) with clear descriptions, making them easily distinguishable.
All tools share the 'theharvester_' prefix and use snake_case, but the suffixes vary between nouns (e.g., emails, hosts) and verbs (e.g., search, check_status), causing slight inconsistency.
With 8 tools, the set is well-scoped for theHarvester's OSINT functionality, covering both broad and focused operations without unnecessary redundancy.
The tool surface covers the major features of theHarvester: general search, source enumeration, DNS brute force, email/host harvesting, Shodan integration, and a comprehensive full recon, with no obvious gaps.
