Each tool targets a distinct step: starting a session, searching, fetching a page, and recording an approval. The two research_-prefixed tools (start vs approve) are semantically different but share a prefix, which could cause minor momentary confusion.

All names use snake_case with a clear verb_noun pattern (research_approve, research_start, web_search, web_fetch). The only deviation is the mixed research_ vs web_ prefixes, which is cosmetic rather than confusing.

Four tools map cleanly onto the research workflow (start, search, fetch, approve) with no redundancy. Slightly lean but well-scoped; no obvious filler.

The core loop of session start, search, fetch, and approval is covered. Minor gaps like an explicit session-end or session-status operation exist but are not blocking for the described workflow.
