create-area

A setup guide for creating a shared work area for related projects, such as websites, research, blogs, videos, or apps. The area stores common rules that its projects can inherit.

In plain words
What is it for?
Use it when starting a new group of related projects and defining their common standards. It helps create the area’s folders, rules, and supporting files in the user’s language.
Why use it?
It prevents the same rules from being rewritten differently in several projects. A shared set of criteria keeps related work consistent.

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

create-area 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.

How it starts

The opening of the file, as written. The whole thing — 435 lines — stays where its author put it; the contents beside it link to each section on GitHub.

create-area — Start a new work area

You are writing the same rule into a third repository. Not copying it — rewriting it, slightly differently each time, because you half-remember how you phrased it last time. In six months those three versions will disagree and none of them will be marked as the wrong one.

That is the problem an area solves. This skill creates the mother folder of a domain (web, research, blog, video, apps…) with its own body of criteria (area Lore) that its projects inherit. It is the "mold of molds": create-project creates projects INSIDE an area; create-area creates the area.

Startup golden rule: the Lore's content is BORN from a brainstorm, not from a template filled in blind. The template gives the shape; the brainstorm gives the content.

Language rule: write EVERYTHING the skill generates — content AND artifact filenames — in the user's language (the language they speak during the brainstorm), NOT the language this skill is written in. The names used throughout this skill (identidad.md, principios.md, FASES.md, proyectos/) are the Spanish canonical forms: localize them (e.g. English → identity.md, principles.md, PHASES.md, projects/). Fixed in every language: the selected contract name (CLAUDE.md or AGENTS.md), lore/, index.md, golden-paths.md, _starter/, the <!-- lore:always-on --> marker pair (literal, never localized — localizing it breaks idempotent stamping silently). English terms of general technical use (workflow, stack, commit, scaffold, starter…) stay in English regardless.

Area model (federated + hybrid)

  • The area is a light folder: one instruction contract + FASES.md + lore/ + proyectos/ + _starter/.
  • The area carries its own project scaffold in _starter/ — the templates ({{CONTRACT_FILE}}.template.md, FASES.md, and golden-paths.template.md when the domain warrants it) tuned to this area's domain, plus any base code scaffold (e.g. a Next.js app for a web area). create-project stamps new projects from {area}/_starter/, so each area's projects are born in that area's shape.
  • New projects are born inside proyectos/ (via create-project), inheriting the area Lore.
  • Existing projects are ADOPTED by registration in FASES.md (with their path), without moving them or touching their git.
  • This skill does NOT adopt projects: it only creates the area clean. Adopting an existing project is a later manual step (add its row to FASES.md).
  • The area Lore distills the domain's cross-cutting method and standard, NOT one concrete project's theory. A project consumes and feeds that standard; its own theory lives in the project's lore/.

create-area is a skill published in the GitHub repository andresanemic/lore-plugin (6 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 5,665 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
