plan-epic

A planning command for defining one outcome that will be delivered through several smaller work slices. An epic is a larger piece of work made up of related parts.

In plain words
What is it for?
It creates or revises an `EPIC.md` file, links the epic to its originating idea when relevant, checks a nearby roadmap, and records the main outcomes and next command.
Why use it?
It turns an idea or existing hypothesis into a shared plan with clear boundaries and recorded decisions.

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.

Or install planner, the plugin that ships this one along with the rest of its 4 skills, 9 commands, 1 agent.

Per session 35 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 490 The whole file, excluding the scripts and references it only reads on demand.

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

plan-epic 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 3d 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.

What it actually says

Активируй скилл product-discovery с видом документа epic и выполни его порядок работы от начала до конца. Для этого вида скилл загружает references/epic-mode.md.

Разбор $ARGUMENTS:

  • Путь к замыслу с решённым исходом epic — гипотеза происходит из замысла: передай его в sync флагом --parent, чтобы помощник зафиксировал блок происхождения.
  • Путь к существующей гипотезе (EPIC.md или её каталогу) — продолжение или пересмотр; сначала посмотри состояние через inspect.
  • Достаточно сформированный свободный текст — допустим, только если уже называет проблему, ожидаемый результат и границу. Если границы нет — следуй правилам справочника, не выдумывай её.
  • Пустой аргумент — уточни у человека, из какого материала строить гипотезу.

Значимые решения задавай через AskUserQuestion по протоколу скилла.

Успешный запуск всегда записывает результат в epics/EPIC-NNNN-<slug>/EPIC.md. После успешной записи в чате — только короткий итог по формату скилла: вид, путь и версия, два–четыре главных исхода, следующая команда, когда она есть. Следующую команду не выполняй сам. Если рядом лежит ROADMAP.md, итог отмечает результат его проверки свежести. Полный документ в чат не дублируется.

Метод, условные методы и проверка готовности — в скилле; не повторяй их здесь. При ошибке записи следуй разделу «Ошибка записи» скилла: подготовленное тело документа — запасной результат.

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.
