product-baseline

product-baseline is a skill for Claude Code from spumer/i-m-senior-developer. It costs 108 tokens per session (1,714 once invoked), scanned A, original, MIT.

A limited fallback for product discovery, the process of turning an idea into a clearer problem, outcome, scope, and assumptions. It organizes information already provided by the user and does not perform outside research.

In plain words
What is it for?
Use it to shape ideas, epics, roadmaps, or feature proposals into a consultation draft for a person to review.
Why use it?
It gives a structured draft when no suitable external product-discovery provider is available, while making clear which points are only hypotheses.

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

product-baseline 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.

Product baseline — встроенный ограниченный поставщик

Назначение и рамка

Минимальная продуктовая проработка, когда подходящего внешнего поставщика нет. Основная команда — скилл product-discovery — вызывает этот скилл последним шагом выбора, после того как внешние кандидаты не прошли: недоступны, покрытие недостаточно или их ответ нарушает договор.

Самостоятельно скилл продуктовую работу не начинает. При доступном внешнем поставщике с полным покрытием встроенный не выбирается.

Честная рамка: у скилла нет доступа к людям, данным о пользователях и внешней проверке. Всё, что он делает, — упорядочивает и формулирует уже принесённое во входе. Новых сведений он не добавляет: порождённые им порядок и гипотезы точек зрения остаются предложениями и гипотезами, а не данными, и помечаются как гипотезы. Он делает вход пригодным для решения человеком. Это запасная ограниченная опора, а не замена внешней продуктовой команды, и ограниченный режим не скрывается: он виден в каждом ответе и попадает в итог запуска основной команды.

Вход

Скилл получает от основной команды:

  1. вид документа (idea, epic, roadmap или feature);
  2. текущую формулировку задачи;
  3. уже собранные утверждения с их типом (наблюдение, внешний источник, допущение, POV-гипотеза, неизвестное);
  4. список требуемых способностей;
  5. явный запрет записи файлов.

Чего во входе нет, того нет у скилла и не появится: недостающее фиксируется в unknowns и limitations, а не додумывается. Утверждение без источника во входе — не наблюдение, а допущение.

Выход

Консультационный черновик с полями:

problem
outcome
actors
scope_in
scope_out
assumptions[]
unknowns[]
candidate_slices[]        # для epic и roadmap
recommended_outcome       # для idea
limitations[]

Правила:

  • обязательны всегда problem, outcome и limitations; ответ без любого из них отклоняется целиком;
  • остальные поля заполняются тем, что есть во входе; пустой перечень честнее выдуманного;
  • каждое утверждение сохраняет свой тип: наблюдение не превращается в проверенный факт, допущение — в знание, гипотеза точки зрения — в отзыв.

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.
