Where the spend went
Spend, by kind of work and by skill.
Every session is priced from its own tokens and tagged with the kind of work it was. Add them up and you see what the spend went to, and how much of it landed in sessions that needed heavy rework.

Stream large CSV exports in chunks
Ines DuarteThu, Sep 24Claude Code52 minEst. $6.40
How it went
- Planninghigh
Asked for an approach before any edits. The agent proposed streaming rows in fixed-size chunks, and the plan held.
- Testinglow
A subagent wrote export tests and ran the focused suite once. It passed.
- Reviewingabsent
Nobody, human or agent, reviewed the diff in this session.
- Reworklow
The chunk writer was rebuilt after two corrections: first its size, then when it flushes.
Steps
- PlanProposed streaming rows in fixed-size chunks instead of building the file in memory.
- ImplementReplaced the in-memory export with a chunked writer.
- CorrectionChunks of 10,000 rows, not 1,000.
- CorrectionFlush each chunk as it is written, not at the end.
- Testwrite-tests · subagentWrote export tests. The focused suite passed.
- DoneLeft the change ready to commit.
- Corrections
- 2Times Ines redirected the agent. A count, not a quality score.
- Expected, unused

Weekly Rewind
Each engineer gets their own Weekly Rewind.
Every week, VibeCheck reads an engineer’s own sessions and suggests one change to try, with the sessions it came from and a prompt they can paste into their agent.

A tip to try
Ask for a review pass before you commit.
4 of your 11 sessions this week ended without a review of the diff, by you or the agent.

Your prompt · Thu, Sep 24
Stream the ledger CSV export in chunks so large exports don’t run out of memory.
Try
Stream the ledger CSV export in chunks so large exports don’t run out of memory. Before you finish, review the diff and list anything you’d flag in code review.

Private summaries
Her summaries can stay hers.
Turn on private summaries and each engineer’s summaries and Weekly Rewind are theirs alone. You still see the shape of every session: how it went, what it cost, and how many corrections it took.
Ines seesEverything
Stream large CSV exports in chunks
Replaced the in-memory CSV export with a writer that streams rows in chunks. Ines asked for a plan first, corrected the chunking twice, then had a subagent write and run the export tests.
