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

GOAL

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.

  1. Prompt · +0
    Implement previously suggested benchmark improvements for word boundary detection and compare current method vs previous method
  2. Agent did · +0m
    Investigated git history, found branch diverged before main merged the labeled dataset work, and switched to a fresh branch off main to avoid stale deletions
  3. Agent did · +1m
    Rewrote 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
  4. Agent did · +2m
    Ported 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)
  5. Fail · +3m
    Silence-gap detector barely improved on Whisper alignment (3/13 vs 1/13) and wasn't good enough to ship
  6. Agent did · +5m
    Reverted the detector wiring and module, kept only the honest benchmark comparison, reran tests green, and committed on the clean branch
  7. Prompt · +9m
    Update the notebook to track this data-science method, including the labeled dataset
  8. Agent did · +10m
    Rewrote the benchmark notebook around the committed manual labels and added a compact benchmark section to the post-tuning notebook; committed both
  9. Intervention · +14m
    Developer said not to commit on their behalf and asked to undo the commit while keeping the changes
    Why: I don't like the agent committing for me; I want to review git changes myself before they're committed.
  10. Intervention · +19m
    Developer 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 change
    Why: Notebook 02 was unrelated scope creep; I threw those changes out and wanted to fold in only the real benchmark work.
  11. Outcome · +20m
    Ended 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
VERDICT

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.
