1## Activation Contract

3Load this skill when a planned PR may exceed **400 changed lines**, an ODD feature's forecast or running authored changed-line count from work-unit commits exceeds about 400, or the user asks for chained/stacked PRs, review slices, or reviewer-load control. The per-task advisory 400 authored-line heuristic does not itself require a PR split.

5## Hard Rules

7- Recommend slicing PRs over **400 changed lines**; offer the ordered oversized-delivery menu below and follow the user's selection subject to the destination repository's documented contribution/size policy.
8- `size:exception` is a Gentle-owned repository policy, not a universal label requirement. Never request, create, or add this label for generic users unless the destination policy uses it. Preserve that policy's maintainer acceptance gates and protected-label human authorization; selection alone grants neither.
9- The budget constrains how work is **sliced**, never the code itself. Never delete comments, blank lines, docs, or tests, and never compress or restyle code, to fit under the budget.
10- Slicing is bounded: make **one** honest slicing pass. If no cohesive split brings every slice within budget, stop iterating, keep the best cohesive split, and report the final line count and rationale. Recommend a size exception only when the destination policy provides that route.
11- Keep each PR reviewable in about **≤60 minutes**.
