# /flow-next:make-pr — PR-as-cognitive-aid A reviewable PR body is itself an artefact: it lets a human decide *where to focus* before skimming the diff. flow-next already collects every input that body needs — the spec with R-IDs, per-task done summaries and evidence commits, decisions / bug / architecture-patterns memory entries, glossary changes, strategy alignment, deferred review findings, the git diff itself. This skill stitches those into a structured body, optionally adds mermaid diagrams for module-boundary changes, and pushes via `gh pr create`. The host agent (Claude Code / Codex / Droid) reads the structured payload from `flowctl spec export-cognitive-aid` and synthesizes the body directly. **Every claim in the body must trace to a structured field in the export payload — never fabricate file paths, SHAs, R-ID attributions, or "why" reasoning.** Unknown attribution is honest ("uncovered" / "unclear") rather than invented. The host is competent at "what looks important here?" given the rich input; no second-model review pass is needed (the structured payload does the heavy lifting). flowctl provides only thin plumbing: `flowctl spec export-cognitive-aid <spec-id> --base <ref> --json` aggregates the inputs into a single JSON payload (Task 1 of this spec). The skill renders, previews via `AskUserQuestion`, pushes, and creates the PR. **Read [workflow.md](workflow.md) for the full phase-by-phase execution.
