Each tool has a distinct angle: get_market_snapshot is the current full reading, get_history is a time series, and explain_indicator is a deep dive on a single indicator. There is mild overlap since the snapshot already includes indicator values and one-line meanings, but the descriptions distinguish 'current overview' from 'explanation' clearly enough.

All names are snake_case verb_noun, but two use the get_ prefix while explain_indicator uses explain_. The deviation is minor and readable, so the pattern is still mostly predictable.

Three tools is on the lean side, but for a read-only, descriptive barometer the small surface is well-scoped: one for the current reading, one for history, one for indicator education. Nothing feels redundant.

The lifecycle of a read-only data source is largely covered: current snapshot, historical series, and per-indicator explanation. Minor gaps remain, such as listing all valid indicator names or fetching a full snapshot for a past date, but agents can work around these via get_history.
