    "taskDescription": "This task takes the MP3 file from the previous subagent, processes it with advanced source separation algorithms to isolate vocal elements and instrumental background into distinct audio stems.",
    "inputDescription": "The input is the MP3 file URL from Subagent 1's output. This file will be analyzed to extract the vocal track and the instrumental track. No additional parameters are required for this operation.",

    "inputDescription": "This task requires a single input: the URL of the MP3 audio file obtained from the YouTube download step. The audio processing engine analyzes the signal to identify beatpoints, measure tempo, and generate a textual description of the track's rhythmic structure.",
    "inputRequired": ["youtube_mp3_file"],

    "taskDescription": "This task takes the textual output from the tempo analysis step, which includes beat points and amplitude data, and uses a language model to parse out and return only the numeric BPM value. All other information is disregarded.",
    "inputDescription": "This task requires the textual breakdown generated from the previous step, which contains data on beatpoints and estimated tempo. The input is processed by a language model to extract only the essential BPM reading.",

Return ONLY the numeric value, with no additional text or explanation. If the BPM appears as a range, return the average. If multiple BPM values are detected, return the most prominent one. Examples of valid responses: '128' or '96.5'. Do not include 'BPM' or any other text in your response. Input: [Previous tempo analysis text]"
