philosophy

A development manifesto describing vmkteam’s preferred Go coding practices, design principles, and architecture habits. It is a reference for making code simpler and decisions more consistent.

In plain words
What is it for?
Use it when designing or reviewing Go code, choosing between implementation approaches, or explaining architectural decisions to a team.
Why use it?
It provides shared guidance for resolving style and architecture questions instead of relying on personal preference.

Or install vmkteam-developer, the plugin that ships this one along with the rest of its 35 skills.

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

philosophy 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 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.

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.

Philosophy — манифест vmkteam

Принципы разработки vmkteam. Источник: https://vmkteam.dev

Код

  • Пиши простой код. Думай о том, кто будет его читать через год
  • Кодогенерация лучше ручного кода. Меньше ручного кода — меньше багов
  • Не используй интерфейсы без необходимости. Конкретные типы понятнее
  • Каждый слой имеет свои модели. Конвертеры между слоями обязательны
  • Три строки простого кода лучше одной умной абстракции

Go idioms we follow

Конкретные правила, которых придерживаемся на всех слоях. Большинство — mainstream Go, часть — vmkteam-специфика (явно помечено).

Базовые

  • context.Context — всегда первый аргумент (после receiver), никогда не в структурах
  • error — последний возврат. Ошибки не теряются
  • Обёртывание: fmt.Errorf("context: %w", err). Проверка: errors.Is / errors.As. Свои типы ошибок — через структуру с методом Error(), а не sentinel string
  • defer для ресурсов сразу после захвата. defer rows.Close(), defer mu.Unlock()
  • Zero-value ready типы — структура должна быть валидна без конструктора, когда это возможно

Типы и пакеты

  • "Accept interfaces, return structs" — принимающие функции/методы работают с интерфейсами, фабрики возвращают конкретные типы
  • Интерфейсы объявляются на стороне потребителя, не провайдера
  • Короткие имена пакетов, одно слово. Никаких util, common, helpers
  • Экспорт по необходимости — начинай с lowercase, поднимай регистр когда появляется реальный внешний потребитель

Конкурентность

  • Не запускай горутины без способа их остановить. ctx + errgroup — базовый паттерн
  • Каналы для сигналинга, мьютексы для разделяемого состояния — не наоборот
  • Background-процессоры — метод Run(ctx) error, возврат при ctx.Done() (см. /gold-arch)

Именование

  • Getters без префикса Get: user.Name(), не user.GetName()
  • Аббревиатуры в одном регистре: userID, HTTPServer, URL
  • Переменная цикла — i, u (короткое), параметр функции — длиннее и содержательнее

Производительность

  • Не оптимизируй без бенчмарка. testing.B + go test -bench
  • pprof через /appkit когда нужно искать узкие места на живом сервисе

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.

philosophy is a skill published in the GitHub repository vmkteam/claude-plugins (7 stars, last pushed 4mo ago), licensed MIT. It adds 58 tokens to every session and 1,472 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
