Delta
Keeps every agent conversation and code diff attached together, from the team that built Zed.
A workspace from the team behind Zed where coding-agent conversations, diffs and code live together, so the reasoning behind a change stays attached to the result instead of disappearing into chat history. In the example shown, a reviewer asks for a benchmark before merging a caching optimization, gets concrete before/after numbers (41.2µs down to 3.4µs on a tree of one million items), then asks for the per-node memory cost and gets an exact answer: 16 bytes per internal node, about 5MB per 10 million items.

What holds up
- +Keeps every agent conversation and diff attached to the code it produced, not lost in chat history.
- +Reviewers can demand a before/after benchmark before merging a performance claim.
- +Built by the team behind Zed, reusing the same SumTree structures that power its editor.
