get_chord_chart_by_name
Look up one guitar chord chart by name and return it as a text chord diagram ready to show the user. Returns the same single voicing that https://guitarpracticeroutine.com/find-a-chord-chart shows for that name. The library holds 12,708 standard-tuning (EADGBE) chord names, exactly one voicing each.
get_chord_chart_by_id
Fetch one specific chord voicing by its numeric id, as returned by get_chord_chart_by_name. Use this to re-render a chart the user already saw without looking it up again.
get_chord_of_the_day
Return today's Chord of the Day from Guitar Practice Routine App — the same chord posted to the app's Bluesky and Facebook feeds that day. Useful as a practice prompt or a daily nudge for someone learning chords.
send_feedback
Send feedback about this chord chart server: a chord or capability you needed that its tools could not provide, a problem with a chart or a result, or praise. Only for feedback about these chord chart tools, not about other tasks. Do not include personal information about the user.
