create-domain-section

A workflow for adding a new knowledge section when an existing Agent Core or project structure does not cover a major topic.

In plain words
What is it for?
Use it to decide whether a new section belongs to agent rules, project knowledge, raw sources, or temporary output, then identify its proper location.
Why use it?
It helps keep new information organized without creating unnecessary sections or placing source documents in the wrong area.

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.

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

create-domain-section 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.

create-domain-section

Назначение

Помогает аккуратно добавлять новые разделы без самовольного разрастания структуры.

Когда использовать

  • Появился новый крупный домен знаний.
  • Существующих разделов Agent Core или active project layer недостаточно.
  • Пользователь передал материал, который требует отдельного раздела.
  • Нужен новый повторяемый business/project раздел для выбранного project layer.

Scope routing

Перед предложением раздела определить scope:

  • Agent Core section — относится к модели агента, protocols, skills, planning, work plans, reference sources.
  • Project section — относится к выбранному project layer: компания, роль, цели, продукты, продажи, CRM, рынок, конкуренты, маркетинг, управление, playbooks или новый business domain.
  • Raw/source section — относится к исходникам и должен жить в raw/, а не в content layer.
  • Output section — временный результат и не должен становиться постоянным разделом без отдельного решения.

Фактический project_id берётся из projects/index.md после выбора active project.

Target paths

  • Agent Core sections: agent/<section>/ only if это действительно часть постоянной агентской сущности.
  • Project sections: projects/<project_id>/<section>/.
  • Raw sources: raw/sources/<source-name>/ или другой согласованный raw path.
  • Output: output/.

Новые project roles or business domains должны создаваться внутри выбранного project layer, а не в Agent Core.

Процедура

  1. Объяснить, почему нужен отдельный раздел.
  2. Определить scope: Agent Core, active project, raw/source или output.
  3. Проверить, нельзя ли использовать уже существующий раздел.
  4. Предложить название папки и базовую структуру.
  5. Показать связи с уже существующими разделами.
  6. Указать, какие индексы нужно обновить.
  7. Сформировать предложение изменения через propose-file-change.
  8. Создать раздел только после подтверждения пользователя.
  9. После создания обновить релевантные index/hub files and logs.

Index updates

Для Agent Core section обычно проверить:

  • agent/index.md;
  • профильный index/hub в agent/model/, agent/protocols/, agent/planning.md, agent/work-plans/ или agent/skills-index.md;
  • agent/model/structure.md, если меняется сама структура Agent Core.

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.
