AI sales pitch coach that logs feedback on every HubSpot deal

Build me an AI sales pitch coach for my reps. It should turn every practice recording into scored, deal-linked coaching notes that a sales manager can read directly on the HubSpot deal.

Trigger: run on a cron every 15 minutes.

Each run, do the following:

1. Call Notion 'Query a Database' on my 'Pitch Practice' database and pull rows where Status = 'pending'. Each row has an audio file URL, the rep's name, and the associated HubSpot deal ID that the rep is practicing for.

2. For each pending row, call Speechace 'Score Speech (Open-ended, Relevance, Language Detection)' on the audio to get the transcript plus fluency, pronunciation, grammar, vocabulary, and coherence scores. Skip rows where the audio is silent or too short to score.

3. Optionally call HubSpot 'Get Deal' on the deal ID to pull deal name, stage, amount, and associated contact/company so the coaching can reference the actual deal context. If a contact is associated, that's fine, no need to fetch it separately unless it makes the coaching materially better.

4. Synthesize a short, constructive coaching write-up grounded in the Speechace scores AND the deal context. It should include: two specific things the rep did well, one specific thing to work on before the next real call, and one suggested phrasing tweak drawn from a real line in the transcript. Cap the write-up at ~150 words. Keep the tone constructive and specific, never generic.

5. Call Notion 'Update a Page' on the same practice row to write the overall score and the coaching write-up back onto the row, and flip Status from 'pending' to 'graded'.

6. Call HubSpot 'Create Note' with a slightly shorter version of the coaching write-up, associated to the deal ID from the row, so the sales manager sees the feedback directly in the deal record.

Guardrails: cap the note at ~150 words, always tie feedback to the actual transcript rather than generic advice, and never flip Status to 'graded' unless both the Notion update and HubSpot note succeeded.
