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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00197 | $0.01866 |
| Opus 5 | $0.00098 | $0.00933 |
| Sonnet 5 | $0.00039 | $0.00373 |
| Haiku 4.5 | $0.00020 | $0.00187 |
Grade B, and why
claude-env-setup scanned grade B with 1 finding 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 today.
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.

Установка и обновление окружения агента
Ставит набор из этого репозитория и связанные с ним инструменты. Два сценария - чистая машина и дозагрузка на рабочей - обслуживаются одним и тем же путем: сперва опись, потом план, потом установка выбранного. Режим не спрашивается у пользователя, а выводится из описи.
Главное правило: не сломать то, что уже работает. На рабочей машине у пользователя есть свои скилы, свои правки в наших, свои MCP-серверы и запущенные сеансы. Ни один шаг не имеет права перезаписать чужое молча. Механика защиты -
references/safety.md, она обязательна к прочтению перед первой записью в любой файл конфигурации.
Порядок работы
Шаг 1. Опись
Снять фактическое состояние машины. Не спрашивать пользователя о том, что можно посмотреть.
# что уже установлено из набора
ls ~/.claude/skills ~/.claude/rules ~/.claude/commands 2>/dev/null | head -50
# конфигурация MCP: два разных файла, оба важны
python -c "import json,pathlib;p=pathlib.Path.home()/'.claude'/'settings.json';print(sorted(json.loads(p.read_text(encoding='utf-8')).get('mcpServers',{}))) if p.exists() else print('нет settings.json')"
python -c "import json,pathlib;p=pathlib.Path.home()/'.claude.json';print(sorted(json.loads(p.read_text(encoding='utf-8')).get('mcpServers',{}))) if p.exists() else print('нет .claude.json')"

else { "$p : свободен" }
}
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-env-setup is a skill published in the GitHub repository Desko77/claude-code-skills-1c (62 stars, last pushed yesterday), licensed MIT. It adds 197 tokens to every session and 1,866 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
