# GitHub Code Review Perform code reviews on local changes before pushing, or review open PRs on GitHub. Most of this skill uses plain `git` — the `gh`/`curl` split only matters for PR-level interactions. ## Prerequisites - Authenticated with GitHub (see `github-auth` skill) - Inside a git repository ### Setup (for PR interactions) ```bash if command -v gh &>/dev/null && gh auth status &>/dev/null; then AUTH="gh" else AUTH="git" if [ -z "$GITHUB_TOKEN" ]; then if [ -f ~/.hermes/.env ] && grep -q "^GITHUB_TOKEN=" ~/.hermes/.env; then GITHUB_TOKEN=$(grep "^GITHUB_TOKEN=" ~/.hermes/.env | head -1 | cut -d= -f2 | tr -d '\n\r') elif grep -q "github.com" ~/.git-credentials 2>/dev/null; then GITHUB_TOKEN=$(grep "github.com" ~/.git-credentials 2>/dev/null | head -1 | sed 's|https://[^:]*:\([^@]*\)@.*|\1|') fi fi fi REMOTE_URL=$(git remote get-url origin) OWNER_REPO=$(echo "$REMOTE_URL" | sed -E 's|.*github\.com[:/]||; s|\.git$||') OWNER=$(echo "$OWNER_REPO" | cut -d/ -f1) REPO=$(echo "$OWNER_REPO" | cut -d/ -f2) ``` --- ## 1. Reviewing Local Changes (Pre-Push) This is pure `git` — works everywhere, no API needed. ### Get the Diff ```bash # Staged changes (what would be committed) git diff --staged # All changes vs main (what a PR would contain) git diff main...HEAD # File names only git diff main...HEAD --name-only # Stat summary (insertions/deletions per file) git diff main...HEAD --stat ``` ### Review Strategy 1. **Get the big picture...
