decompose

decompose is a skill for Claude Code from vmkteam/claude-plugins. It costs 46 tokens per session (2,570 once invoked), scanned A, original, MIT.

A workflow for researching a large or unclear User Story—a description of a desired product change—and breaking it into smaller tasks in YouTrack, a project-management tool.

In plain words
What is it for?
Use it before solving a large YouTrack issue to check the current code, record research, identify dependencies, and create actionable subtasks.
Why use it?
It turns a vague request into an investigated, ordered plan based on the code and its dependencies. It also pauses for approval before major stages and before creating tasks.

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 A, and why

decompose 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 23d 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.

Flow

PREFLIGHT → FETCH → RESEARCH → ⏸ HITL → DECOMPOSE → ⏸ HITL → CREATE → ⏸ HITL

0. PREFLIGHT — актуальность базовой ветки

Перед workflow проверить, что локальный базовый бранч синхронизирован с origin — иначе research пойдёт по устаревшему коду.

Имя базовой ветки — из project-index.md (base_branch, по умолчанию devel).

git fetch origin {base_branch} --quiet && git rev-list --left-right --count {base_branch}...origin/{base_branch}

Вывод 0 0 — база актуальна. Иначе ⏸ HITL через AskUserQuestion:

  • Обновить — на базовой ветке: git pull --ff-only; на другой ветке: git fetch origin {base_branch}:{base_branch}
  • Продолжить — на устаревшей базе, явно предупредив пользователя
  • Отмена

1. FETCH — прочитать задачу

Получить задачу из YouTrack:

pcurl @{yt_profile} 'https://{yt_host}/api/issues/{TASK_ID}?fields=idReadable,summary,description,created,updated,reporter(login,name),assignee(login,name),tags(name),comments(author(login,name),text,created),customFields(name,value(name))' -s

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.
