A workflow for starting work on a GitHub issue by creating a separate Git worktree and a correctly named branch. A worktree is another working folder connected to the same Git repository.

It helps read an issue, determine whether the work is a feature, fix, or maintenance task, create the matching branch, and check whether work is already in progress.

It prepares an isolated workspace for one task and reduces confusion between branches or unfinished changes. It also uses issue labels and descriptions to choose a branch type and name.

start-issue — Command for Claude Code by dapi/claude-code-marketplace

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/dapi/claude-code-marketplace

Made for: Claude Code.

Or install github-workflow, the plugin that ships this one along with the rest of its 3 skills, 1 command.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00016	$0.01894
Opus 5.5	$0.00006	$0.00758
Sonnet 5.5	$0.00003	$0.00379
Haiku 4.5	$0.00002	$0.00189

Security

Grade A, and why

start-issue scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Входные данные

ISSUE_URL: $ARGUMENTS (ссылка на GitHub issue)

Формат имени ветки

<тип>/<номер-задачи>-<описание>

Типы веток

Тип	Когда использовать
`feature`	Новая функциональность
`fix`	Исправление бага
`chore`	Рефакторинг, зависимости, CI, документация

Определение типа

По labels issue:
- bug, fix → fix
- enhancement, feature → feature
- chore, refactor, docs, ci, dependencies → chore
Если labels нет — определи по заголовку/описанию issue

Формирование описания (slug)

Lowercase
Пробелы и спецсимволы → дефисы
Множественные дефисы → один дефис
Максимум 50 символов
Убрать дефис в конце

Примеры:

feature/123-add-user-authentication
fix/456-null-pointer-in-parser
chore/789-update-eslint-config

Шаги выполнения

Прочитай GitHub issue по ISSUE_URL:
- Номер issue
- Заголовок
- Labels (для определения типа)
- Описание (если нужно для понимания типа)
Проверь лейбл progress:

Если issue уже имеет лейбл progress:
- Сообщи пользователю: ⚠️ Issue уже имеет лейбл 'progress' — возможно, над ней уже ведётся работа.
- Спроси: продолжить или отменить?
- Если пользователь отменяет — заверши выполнение команды
Сформируй имя ветки по шаблону <тип>/<номер>-<slug>

Slug формируй bash-командой (гарантирует отсутствие trailing hyphen):
```
SLUG=$(echo "<title>" | tr '[:upper:]' '[:lower:]' | sed 's/[^a-z0-9]/-/g; s/-\{2,\}/-/g; s/^-//; s/-$//' | cut -c1-50 | sed 's/-$//')
BRANCH_NAME="<тип>/<номер>-${SLUG}"
```
Создай git worktree от текущей ветки:

Сформируй переменные:
- BRANCH_NAME — имя ветки из шага 3 (например fix/123-some-bug)
- WORKTREE_NAME — имя директории: замени / на - (например fix-123-some-bug)
- WORKTREE_PATH — полный путь: ~/worktrees/<WORKTREE_NAME>

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.
