dev-github-workflow

An automation guide for Git, the version-control system used to record code changes, manage branches, and collaborate through pull requests. It covers committing, branching, opening pull requests, and merging.

In plain words
What is it for?
Use it to inspect repository state, choose changes for a commit, create commit messages, and manage approved GitHub changes.
Why use it?
It structures the Git workflow and asks for approval before changes are committed or pushed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

dev-github-workflow scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Code's default Co-Authored-By trailer is disabled at install via the `attribution` setting in `~/.claude/settings.json` (set during `/design-engineer:launch`), so neither mode includes it.

How it starts

The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git Workflow Automation

Handles commits, branches, pull requests, and merges. Works in two modes: automatic (called during plan execution after each approved phase) and manual (user invokes directly to commit changes).

For Git concepts and educational content, see github-for-designers.md.

Interaction Method

If AskUserQuestion is available, use it for all prompts below.

If not, present each question as a numbered list and wait for a reply before proceeding. For multiSelect questions, accept comma-separated numbers (e.g. 1, 3). Never skip or auto-answer without explicit user consent.


Step 0: Before starting

  1. Announce your execution plan: Before doing anything, state what you will do in this activity: "Here's what I'm going to do: 1) check the current git state and branch, 2) determine what to include in the commit, 3) generate a commit message following Conventional Commits format, 4) commit and push after your approval." This is a commitment device – harder to skip steps you just announced.

  2. Conditional teaching: Ask the user if they are familiar with Git basics – commits, branches, and pull requests. If yes, give a one-sentence refresher on the Conventional Commits format used here. If no, explain it in simple terms: Git tracks every change you make so you can go back if something breaks – commits are save points, branches are parallel versions, and PRs are how you merge work back together. Refer to github-for-designers.md for a deeper walkthrough.

    Required: ALWAYS ask the question, ALWAYS give the refresher when the user says yes. Never skip this step because the user "is a designer" or "already demonstrated familiarity earlier." Users want a memory refresh on every activity, including ones they know. Phrases like "I'll skip the explainer (you're a designer)" are forbidden — they signal the model has decided ON BEHALF OF the user that a refresher isn't needed. The user, not the model, decides what's redundant. The refresher takes one sentence; the cost is trivial; the value to a tired user mid-session is high.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dev-github-workflow is a skill published in the GitHub repository volomydyr/design-engineer-plugin (19 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 2,822 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
