Add a pre-push review pass to the agent instructions - #2764
Conversation
Before asking to push, agents review the whole diff against its base as a skeptical reviewer would, and report what they found. If the pass turns up an opportunity, they tell the user and offer to address it instead of pushing as-is. The pass covers performance and memory (measured, especially on GPU), collective symmetry on distributed and offloaded paths, simplicity and reuse of existing mechanisms, validate-before-mutate correctness across the layouts a change can meet, and tests that demonstrably fail without the fix.

Limit regression-test requirements to behavior changes.
Because these instructions apply to all AI-assisted work, “Each fix” also covers documentation-only changes. Those changes may have no meaningful executable regression test. Limit this requirement to behavior fixes and call for suitable validation for other changes.

- Each fix has a test that fails without it; check by reverting.

Bot review (bedrock-claude-opus-5-5) — DM the bot to share feedback.
Approving: this is a docs-only addition of 30 lines to AGENTS.md. It fits with the existing push-approval rule and doesn't contradict any other section.
No action needed.
No action needed:
- The new section sits right after the "never push without approval" rule. That placement makes sense, because the pass runs before the agent asks for push approval.
- The checks match the problems the PR body cites from #2710: the memory peak in the pinned-payload lookup, the duplicate
upcast_ggmloption, and the rank-dependent collective hang. They line up with what reviewers already ask for in this repo. - The skill-conciseness rule doesn't strictly apply, since
AGENTS.mdisn't underskills/. The text is still fairly tight. One optional cut: "Comments say why, not what" partly repeats the CONTRIBUTING coding standards that the Coding guidelines section already links to. - There are no source, test or licensing changes, and markdownlint passes per the PR body.

What does this PR do?
Type of change: documentation (agent instructions)
Adds a Pre-push review pass to
AGENTS.md, whichCLAUDE.mdlinks to. Before asking to push, an agent reviews the whole diff against its base as a skeptical reviewer would and reports what it found. If the pass turns up an opportunity, the agent tells the user and offers to address it before pushing, instead of pushing as-is.The pass checks:
Why: a late review pass on #2710 found several issues that a first implementation passed over:
upcast_ggmlexport option duplicated weight folding. Reusing folding was simpler, once folding was made exact for GPTQ'd weights.Writing the pass into the workflow makes it a step every PR gets, not an afterthought.
Usage
N/A (agent workflow).
