Clef Music Tools

Each tool targets a distinct input/output pair: guide search, chord spelling, tab-to-pitch conversion, and chord transposition. The only mild overlap is that spell_piano_chord and tab_to_piano_notes both emit piano pitches with MIDI values, but their inputs make the boundary clear.

All names are snake_case and lead with a verb (find, spell, tab_to..., transpose). The conversion-style name tab_to_piano_notes deviates slightly from the verb_noun pattern but remains self-explanatory.

Four tools is on the lean side but each corresponds to a real, non-redundant music-theory operation. Nothing is padded or superfluous for the stated scope.

The surface covers one-way operations only: there is no reverse tab generation, no way to enumerate which chords are 'supported' for spell_piano_chord, and no output-side tools (e.g. exporting pitches or chord lists). Agents can still do the advertised tasks but will hit dead ends when they need the inverse or discovery operations.
