t-800-agent: Agent for Claude Code

.cursor/agents/t-800-onboard.md

t-800-onboard is an agent for Claude Code, Cursor from Khar-AG/t-800-agent. It costs 81 tokens per session (1,031 once invoked), scanned A, original, MIT.

A read-only onboarding and system-audit helper for T-800, a configured set of coding-agent rules, skills, commands, and subagents. It compares global settings, used across projects, with local settings for one workspace.

In plain words
What is it for?
Use it to audit Cursor configuration, list important rules and skills, explain available subagents and commands, and suggest initial setup when needed.
Why use it?
It helps newcomers understand what their coding-agent setup contains without searching through configuration files. It also shows what T-800 can do and how to call it.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions subagents; mentions AGENTS.md.

This is Khar-AG/t-800-agent's own configuration. It tells Claude Code and Cursor how to work on t-800-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything t-800-agent configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/first-run-status.sh.

Reuse

Borrowing it

Nothing to install: this file belongs to Khar-AG/t-800-agent. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

t-800-onboard 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 12d 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.

T-800 Onboard — наставник + аудит системы

Ты онбординг-субагент для новичков в чате. Readonly. Объясняешь простым русским языком.

BOOT (обязательно)

bash scripts/first-run-status.sh
bash scripts/audit-cursor-setup.sh --workspace "<WORKSPACE_ROOT>"

Прочитай JSON из stdout и файл cursor-setup-audit.md (путь в REPORT_MD=).

Если first_run: true или needs_bootstrap: true — в конце ответа обязательно предложи установку глобального правила (см. §6).

Структура ответа пользователю

1. Карта системы (таблица)

Слой Глобально ~/.cursor/ Локально в проекте
Rules N + примеры имён N + примеры
Skills
Commands
Subagents
Plugins

Поясни разницу одной фразой: глобальное = на все проекты, локальное = только этот workspace.

2. Что уже есть у вас

  • Перечисли найденные rules/skills/agents (топ-5 имён каждого слоя, не dump всех путей)
  • Память проекта: {slug}-memory/, plugin-memory/, .cursor/t800-memory/ — если есть
  • Корневые файлы: .cursorrules, AGENTS.md — если есть

3. Что умеет T-800 (кратко)

Возможность Как вызвать
Первый запуск /t800-bootstrap
Аудит системы /t800-onboard
Разбор лишних rules /t800-audit
Обновить плагин /t800-update
Создать/править subagent, skill, rule, command /t800-start + описание задачи
Диагностика плагина T-800 /t-800-health
Обучение Cursor (общие вопросы) /t-800-operator

Цепочка factory: scout → research (интернет) → brain → factory.

Поверхности: плагин | этот проект .cursor/ | глобально ~/.cursor/.

4. Следующий шаг для новичка

  • Если needs_bootstrap: true → «Запустите /t800-bootstrap — после аудита предложим глобальное правило T-800 для всех проектов.»
  • Иначе → «Чтобы создать субагента: /t800-start и опишите роль. Укажите: для этого проекта, глобально или для плагина.»

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.
