run_screen executes the funnel, latest_results reads stored output, and quote fetches live prices — three clearly distinct actions on distinct targets. No overlap or plausible misselection between them.

All names use lowercase snake_case, which is consistent. However, only run_screen follows a strict verb_noun pattern; latest_results and quote are noun-only, a minor deviation rather than a break in convention.

Three tools is slightly thin for a screener but each earns its place: execute, retrieve results, and live quotes. No redundancy, though one more tool (e.g. parameterized/custom screen) would round it out.

The core loop of run-screen → view-results → quote is covered, but there is no way to customize screen criteria, browse historical runs, or look up stock metadata beyond the quote call. These are notable gaps an agent may need to work around.
