Each tool maps to a clearly separable concern: the current index/score, the advisory alert feed, and source health diagnostics. An agent can decide between them unambiguously from the names alone, and the descriptions reinforce the boundaries (score vs. alerts vs. upstream feeds).

All three tools follow the same get_<noun> pattern (get_current_index, get_recent_alerts, get_source_health), with snake_case throughout and noun phrases that read naturally together.

Three tools is thin but proportionate for a read-only wrapper over a small public API surface; each tool corresponds to a distinct endpoint and none feels redundant. It could arguably use one more tool (e.g. history), but the scope is tight rather than padded.

The read path for the live signal is well covered (value, alerts, feed health), but there is no way to retrieve historical scores or trends, which is a notable gap for something described as a 'directional signal'. Alert retrieval also lacks filtering by category or time beyond a simple count, leaving some agent workflows to work around the surface.
