π€― My love/hate relationship, and shocking surprises with AI continues...
I gave Claude (usually amazing) a transcript to read and analyze.
It confidently summarized it, commented on it, and we started building on that work together.
What I didn't know? It had only read part of it.
No warning. No disclaimer. Just a partial read presented as a complete one.
It took several rounds of back-and-forth, and me noticing missing details, before the truth came out: by default, Claude samples large files rather than reading them fully.
And it won't tell you that unless you specifically ask.
The fix? A few options:
You can explicitly instruct it to read the entire file every time and ask it to confirm.
Or better yet, add it once to your project knowledge file or system instructions so it applies automatically every session without you having to remember.
Lesson learned the hard way.
Now I'm wondering what else I've missed in past sessions. π€
If you're using AI to work with transcripts, documents, or any uploaded content, don't assume it read the whole thing. Verify.
