One word 'fricative' unlocked full IPA planning: why domain knowledge still wins with coding agents

Matt Pocock shares a lesson from building his video editor: telling his coding agent that certain consonants interfere with silence detection — just the word 'fricative' — made it pull out the full IPA and brainstorm the trickiest consonants. The screenshot shows the agent classifying unvoiced/voiced fricatives and affricates that stretch clip joins, noting voiced fricatives are too loud for a -20dB rule and proposing a 3-pass cut using text to name sounds and waveforms to place cuts. His takeaway: knowing things is really valuable in the agent era.
