Unclear The actual file limits, and what controls whether the artifact publishing feature is available, are not stated.
What
When Claude publishes an artifact and names more files than one publish allows, the error message has changed. It now says:
- Nothing was published.
- One publish may name only a set number of entries, so Claude should send at most that many now.
- The remaining files can be added with further publishes to the same URL.
- Files left out of a later publish are kept, and one version can hold a larger total than a single publish.
The old message said the files were over the limit per version and to publish fewer.
Why
Large artifacts with many files can now be built up across several publishes, instead of being capped at what fits in one go.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
