+# Корпоративный контекст
+
+Ты работаешь как инженерный ассистент внутри нашей компании. Учитывай это во всех задачах.
+
+**Кто мы:** продуктовая инженерная команда. Основной стек — **Go** (микросервисы).
+
+**Где код:** git-хост — `{{gitHost}}`.
+Карта репозиториев: {{repoMap}}
+Подробнее — скилл `repo-map`.
+
+**Трекер задач:** {{trackerUrl}}
+Как читать тикеты и работать с задачами — скилл `jira-workflow`.
+
+**Документация:** {{docsUrl}}
+Как искать и куда писать — скилл `docs-map`.
+
+**Стандарты Go** (структура сервиса, линтеры, тесты, MR) — скилл `go-standards`.
+
+**Базовые правила:**
+{{rules}}
+
+Не выдумывай внутренние адреса и факты: если чего-то нет в этом контексте или в конфиге —
+скажи об этом прямо. Точные действующие значения можно посмотреть командой `/kit-config`.

+ * WHAT: On session start, loads config/company.json (the single source of
+ *       truth). If `remoteConfigUrl` is set, tries to fetch a fresh config
+ *       from there with a short timeout and falls back silently to the local
+ *       file on any error. Renders a short corporate context from
+ *       `company-context.md` and injects it into the system prompt. Also
+ *       registers the `/kit-config` command for debugging effective values.
+ *
+ * CONFIGURE: Edit config/company.json (gitHost, trackerUrl, docsUrl, repoMap,
+ *       rules, remoteConfigUrl). Edit the wording in company-context.md —
+ *       non-programmers can safely change text between the {{placeholders}}.
+ *
+ * DISABLE: Remove/rename this file from the package `extensions/` folder,
+ *       or exclude it via the package manifest / settings.
