Untangle git branches and benchmark word-boundary detection for Read-Along AI
Session from read-along-ai-agent-traces on Hugging Face by kingkw1 · MIT · condensed by Coders Talk
Sort out a messy git branch situation from prior sessions, implement and validate a quantitative benchmark comparing word-boundary detection methods against a manually labeled dataset, then prepare a clean PR and hand off remaining detector work.
- +0Prompt · +0Implement previously suggested benchmark improvements for word boundary detection and compare current method vs previous method
- +0mAgent did · +0mInvestigated git history, found branch diverged before main merged the labeled dataset work, and switched to a fresh branch off main to avoid stale deletions
- +1mAgent did · +1mRewrote benchmark with aggregate hit-rate/error metrics comparing current alignment vs proportional baseline; ran it and found current Whisper alignment only hits 1/13 boundaries in manual labels
- +2mAgent did · +2mPorted a silence-gap detector from an old branch and wired it into app.py, but tuning against real labeled data showed only marginal improvement (3/13)
- +3mFail · +3mSilence-gap detector barely improved on Whisper alignment (3/13 vs 1/13) and wasn't good enough to ship
- +5mAgent did · +5mReverted the detector wiring and module, kept only the honest benchmark comparison, reran tests green, and committed on the clean branch
- +9mPrompt · +9mUpdate the notebook to track this data-science method, including the labeled dataset
- +10mAgent did · +10mRewrote the benchmark notebook around the committed manual labels and added a compact benchmark section to the post-tuning notebook; committed both
- +14mIntervention · +14mDeveloper said not to commit on their behalf and asked to undo the commit while keeping the changesWhy: I don't like the agent committing for me; I want to review git changes myself before they're committed.
- +19mIntervention · +19mDeveloper discarded the notebook 02 changes entirely, saying it had nothing to do with this benchmark work, and asked to focus on merging just the benchmark changeWhy: Notebook 02 was unrelated scope creep; I threw those changes out and wanted to fold in only the real benchmark work.
- +20mOutcome · +20mEnded with a clean branch codex/benchmark-on-main (commit 5998e21) containing only the benchmark notebook and test changes, pushed to origin, decided on squash-and-merge, confirmed an old branch was obsolete, and wrote a handoff prompt for further detector work
Next time I'd start by telling the agent explicitly not to commit anything without asking, since it committed twice before I stepped in to stop it. The intervention that mattered most was catching the scope creep into notebook 02 and unrelated commits — separating 'benchmark comparison' from 'fix the detector' kept the PR honest instead of shipping a detector that only hit 3/13 boundaries. The benchmark itself did its job: it proved neither the current Whisper alignment nor the ported silence-gap detector is good enough yet, so I handed off the actual fix to a fresh session with the labeled data as context.
