The idea in one minute

Start with meaning, then move to detail.

This lesson explains Github Code Review — Review PRs: diffs, inline comments via gh or REST as part of getting started with Hermes correctly. You will learn what it does, when it matters, and the smallest safe test that proves it works.

If you are new

If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?

For hands-on use

For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.

For specialists

For advanced readers, inspect Skill metadata, Reference: full SKILL.md, Prerequisites, then verify failure modes and version compatibility.

What do you need first?

No prior experience is required; follow the steps on a safe test setup first.

What will you know?

A clear outcome before you read.

  • Understand Github Code Review — Review PRs: diffs, inline comments via gh or REST without assumed prior knowledge.
  • Separate the source description from what still needs testing in your environment.
  • Read the first command and identify its inputs and outputs before copying it.

Examples from the official page

Copy only after you understand the effect.

if command -v gh &>/dev/null && gh auth status &>/dev/null; then AUTH="gh" else AUTH="git" if [ -z "$GITHUB_TOKEN" ]; then if _hermes_env="${HERMES_HOME:-$HOME/.hermes}/.env"; [ -f "$_hermes_env" ] && grep -q "^GITHUB_TOKEN=" "$_hermes_env"; then GITHUB_TOKEN=$(grep "^GITHUB_TOKEN=" "$_hermes_env" | head -1 | cut -d= -f2 | tr -d '\n\r') elif grep -q "github.com" ~/.git-credentials 2>/dev/null; then GITHUB_TOKEN=$(uv run python3 "${HERMES_HOME:-$HOME/.hermes}/skills/github/github-auth/scripts/git-credential-token.py") fi fi fi REMOTE_URL=$(git remote get-url ori
# 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
git diff main...HEAD --stat git log main..HEAD --oneline
Try it now

Read the first command and identify its inputs and outputs before copying it.

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.
