Flows Code Review

This runs the technical review step of Flows app certification and spits out three markdown reports: a file inventory with scores for structure, quality, and patterns; a dependency audit flagging outdated packages and CVEs; and a scored report across 12 criteria covering bugs, security, test coverage, DMS query patterns, and performance. It hard-gates on 80% line coverage and enforces that all CDF access goes through the SDK. You run it repeatedly until all Must Fix items are cleared before moving to design review. It's opinionated about dependency injection, testability, and platform patterns, pulling guidance from a local library of skill files that ship alongside it.

Flows Code Review

This skill is the local runner for the technical review step:

flows-app-brief  →  build  →  flows-code-review (this skill, repeat until clean)  →  flows-design-review  →  flows-external-app-submit

Checks and scoring live in flows-review-checks. Do not copy them here. Do not score from memory. Do not substitute test-coverage or other fix skills for the review bar.

This file only decides: git/app-brief pre-checks, feedback-round folder, that the working directory is the app root, where to write files, and the submitter Summary block.

Pre-checks

package.json exists
We are inside a git repository (git rev-parse --git-dir)
If App-Brief.md is missing at repo root, warn that flows-app-brief should be run first, but continue

Feedback round: look at reviews/code-review/. If it doesn't exist, use feedback-round-1/. Otherwise the next missing round number.

Working directory for all review commands: repo root (the app).
