Scored across 19 tools
Most tools are clearly separated by resource and action, and pairs like page_click/page_click_ref are explicitly distinguished via selector-based vs. a11y-ref-based interaction. A couple of input-setting tools (page_type vs page_fill) could be misselected without close reading, but the descriptions resolve this.
The dominant pattern is resource-prefixed actions (page_open, session_create, identity_generate, captcha_solve), which is predictable and readable. Deviations like page_a11y, page_snapshot, and session_evidence are noun-style but follow the same prefix convention, so only minor inconsistency exists.
19 tools is slightly above the ideal 3-15 range but justified by the need for selector-based and ref-based variants plus identity, session, page, and captcha coverage. No tool feels redundant enough to cut outright, though the set is substantial.
The core browsing loop—create session, open page, read, interact, wait, screenshot, collect evidence—is well covered, and identity/captcha workflows are included. Missing session/page teardown (e.g., session_close, page_close) and navigation controls are minor gaps but not blocking for most automation tasks.
