![]() This eval checks that Edit Agent can create an empty file without writing its thoughts into it. This issue is not specific to empty files, but it's easier to reproduce with them. For some mysterious reason, I could easily reproduce this issue roughly 90% of the time in actual Zed. However, once I extract the exact LLM request before the failure point and generate from that, the reproduction rate drops to 2%! Things I've tried to make sure it's not a fluke: disabling prompt caching, capturing the LLM request via a proxy server, running the prompt on Claude separately from evals. Every time it was mostly giving good outcomes, which doesn't match my actual experience in Zed. At some point I discovered that simply adding one insignificant space or a newline to the prompt suddenly results in an outcome I tried to reproduce almost perfectly. This weirdness happens even outside the Zed code base and even when using a different subscription. The result is the same: an extra newline or space changes the model behavior significantly enough, so that the pass rate drops from 99% to 0-3% I have no explanation to this. Release Notes: - N/A |

Licensing
License information for third party dependencies must be correctly provided for CI to pass.
We use cargo-about
to automatically comply with open source licenses. If CI is failing, check the following:
- Is it showing a
no license specified
error for a crate you've created? If so, addpublish = false
under[package]
in your crate's Cargo.toml. - Is the error
failed to satisfy license requirements
for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to theaccepted
array inscript/licenses/zed-licenses.toml
. - Is
cargo-about
unable to find the license for a dependency? If so, add a clarification field at the end ofscript/licenses/zed-licenses.toml
, as specified in the cargo-about book.
