Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

Amp has upgraded its smart mode to use Opus 4.8, replacing Opus 4.7. Internal evals show task completion rising from 52% to 62%. Changes include tighter scope of edits, more self-verification through write-test loops, better tool selection (librarian called 14x vs once, edit_file 79% vs 63%), and removal of the built-in Read tool.

Primary-source release with concrete eval numbers and tool-use patterns. Useful baseline for tracking how coding agents are evolving their default behaviors and tool selection.
