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

changelog-generator 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/changelog_gen.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Changelog Generator

Генерация раздела CHANGELOG из git-истории: анализ commit-логов, группировка по Keep a Changelog секциям, готовый Markdown в stdout или файл.

Загружай этот скилл когда нужно сгенерировать/обновить changelog из истории коммитов для релиза или представительской проверки. Скилл читает git log, классифицирует изменения по типам и выдаёт готовый Markdown.

🎯 When to use

Use this skill when:

  • Нужно сгенерировать CHANGELOG.md перед релизом (секции Added/Fixed/Changed)
  • Нужен «что нового» для PR или release notes
  • Просят «созерай чанлог», «обнови changelog», «история изменений»
  • Нужно быстро посмотреть, какие фичи/фиксы попали в диапазон тегов

Do NOT use when:

  • Лог коммитов нужен «как есть» (без группировки) — это обычный git log
  • Нужна переносим MVP-типов вручную — скрипт уже делает маппинг
  • Репозиторий не использует Conventional Commits — маппинг будет пустым

📦 Files

  • SKILL.md — этот файл
  • scripts/changelog_gen.py — основной скрипт (Python 3 stdlib only)

🔧 Usage

# Unreleased (от последнего тега до HEAD)
python3 skills/changelog-generator/scripts/changelog_gen.py --repo <path> --top

# Для версии между тегами:
python3 skills/changelog-generator/scripts/changelog_gen.py \
    --repo <path> --from-tag v1.0.0 --version 1.1.0

# Включить скрытые типы (docs/ci/chore/test):
python3 changelog_gen.py --repo <path> --top --all

# Записать в файл:
python3 changelog_gen.py --repo <path> --top --out CHANGELOG.md

🔄 Маппинг типов

Conventional Commits Секция Замечание
feat: ... Added Новая функциональность
fix: ... Fixed Багификсы
perf: / refactor: Changed Изменения поведения
revert: Reverts Откаты
breaking (! или BREAKING CHANGE:) Breaking Выносится в свою секцию
docs/style/test/build/ci/chore скрыты Видны только с --all

✅ Definition of Done

  • Скрипт отработал без ошибок: stdout или файл с секциями Added/Fixed/Changed.
  • Breaking-коммиты вынесены в отдельную секцию.
  • Дата и версия в заголовке корректны.
  • Если нужен CHANGELOG.md в репо — содержимое вставлено (по отдельным запросам).
Files

What ships with it

2 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.

Changes

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.
