product-data-auditA skill your agent uses when auditing a product, business, or project ecosystem — analyzing data sources, decision loops, bottlenecks, and implementation contours.
Product Data Audit is an agent skill from serejaris/personal-corp-os. Use when auditing a product, business, or project ecosystem — analyzing data sources, decision loops, bottlenecks, and implementation contours. Triggers on "аудит продукта", "product audit", "data audit", "аудит данных", "аудит бизнеса", "проанализируй экосистему", "аудит систем".
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files and assets (for example `README.md`, `README.ru.md` and `references/html-design-spec.md`).
It sits in Data & Analytics, covering Data analysis. The repository describes itself as: Personal Corp OS — управление личной компанией через AI-агентов: задачи вне головы, отделы вместо памяти, недельное ретро. Открытые скиллы для Claude Code и Codex. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 95e36c3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are dot and bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Product Data Audit loads about 1.3k tokens when it runs, and up to ~8.2k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 492 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

}Спросить у пользователя, если неочевидно:
workdir = корень git-репозитория текущего проекта. Если неочевидно — спросить у пользователя до шага 2.
Обнаружить и прочитать источники по категориям (конкретные файлы зависят от проекта):
Для каждого источника фиксировать: что внутри, дата snapshot, качество, ограничения.
Обнаружение источников: начать с CLAUDE.md / README.md в корне — они обычно описывают структуру проекта и указывают на канонические файлы. Затем ls + glob по корню для обнаружения остального.
Свежесть данных: если snapshot старше 14 дней — добавить [snapshot: YYYY-MM-DD] рядом с числом. Если старше 30 дней — пометить [УСТАРЕЛО: YYYY-MM-DD].
Если канонические файлы не найдены: пометить числовые утверждения НЕИЗВЕСТНО. [источник не найден] и продолжить аудит с доступными данными.
Основной артефакт = HTML ({workdir}/research/product-data-audit.html). Markdown-версия (.md) — опциональна, генерировать только по явному запросу пользователя.
Структура — 12 секций (0–11), см. references/report-structure.md. Секция 0 = диаграмма экосистемы.
Тегирование: каждое утверждение маркировать:
ФАКТ. — подтверждено данными, указать источникГИПОТЕЗА. — логичный вывод, требует проверкиНЕИЗВЕСТНО. — слепое пятно, данных нетПравило числовой конкретики (обязательно):
[файл:строка] или [система → запрос][число не найдено] вместо голого утвержденияТерминология: русский язык, англицизмы только для устоявшихся стандартов (CRM, API, KPI). См. references/terminology.md.
Рекомендации по отсутствующим артефактам: в секции 7 (контуры внедрения) проверить наличие 18 операционных артефактов из references/missing-artifacts-checklist.md. Отсутствующие — включить как рекомендации с приоритетом и минимальной версией. 4 категории: стратегия (NSM, OKR), AI-native (CLAUDE.md, промпты, runbook), инфраструктура данных (SSOT, определения метрик), governance (журнал решений, эскалация).

A skill your agent uses when auditing a product, business, or project ecosystem — analyzing data sources, decision loops, bottlenecks, and implementation contours. Product Data Audit is an agent skill from serejaris/personal-corp-os. Use when auditing a product, business, or project ecosystem — analyzing data sources, decision loops, bottlenecks, and implementation contours.
Product Data Audit fits situations like: auditing a product; project ecosystem — analyzing data sources; implementation contours; Проанализируй экосистему.
Run `npx skills add serejaris/personal-corp-os --skill product-data-audit -a claude-code`. Or copy the skill folder (skills/product-data-audit in serejaris/personal-corp-os) into .claude/skills/product-data-audit in your project. Claude Code loads it when a task matches its description.
Run `npx skills add serejaris/personal-corp-os --skill product-data-audit -a codex`. Or copy the skill folder (skills/product-data-audit in serejaris/personal-corp-os) into .agents/skills/product-data-audit in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add serejaris/personal-corp-os --skill product-data-audit -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/product-data-audit, .gemini/skills/product-data-audit, .github/skills/product-data-audit and .opencode/skills/product-data-audit in your project.
SKILL.md names no scripts, command-line tools or credentials: Product Data Audit is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Product Data Audit is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.3k tokens (SKILL.md is roughly 5.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6.9k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Product Data Audit: Exploratory Data Analysis (spacering-net/codeg, 3.9k stars), Excel and CSV Data Analysis (bytedance/deer-flow, 84k stars), Exploratory Data Analysis (Oleafly/Oleafly, 212 stars) and Pandas Pro (Jeffallan/claude-skills, 12k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
