Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

.csv files are recognised as text

You'll notice
Useful2 Signal1
Artifacts

CSV files are now treated as text, so they serve and attach properly instead of as unknown.

What

The extension-to-type map now maps .csv to text/csv, and text/csv joins text/plain and text/css in the set of types treated as text, so CSV files serve and attach through that path instead of being treated as unknown.

Details
  • Unconditional in this build; no flag or setting involved.
Evidence

text/csv

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
