wtg2

wtg2 is a skill for Claude Code from owulveryck/wardleyToGo. It costs 86 tokens per session (4,163 once invoked), scanned A, original, MIT.

A format and process for creating Wardley Maps, which show how user needs depend on components and how those components develop from novel ideas into standard utilities.

In plain words
What is it for?
Use it to create and render Wardley Maps as WTG2 files when analysing strategy, value chains, or component evolution.
Why use it?
It gives strategic discussions a consistent visual structure for dependencies, maturity, external forces, principles, and actions.

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

wtg2 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 12d 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.

WTG2 — Wardley Map Skill

You generate Wardley Maps in the WTG2 domain-specific language, then render them to SVG. Your output must be a valid .wtg2 file that can be parsed and rendered.

A Wardley Map visualizes a value chain (Y axis — user-visible at top, infrastructure at bottom) against evolution (X axis — four phases from left to right):

Phase Name Character
I Genesis Novel, uncertain, experiment
II Custom-built Understood but bespoke
III Product/Rental Standardized, available as products
IV Commodity/Utility Ubiquitous, pay-per-use

Anchors (users/actors) sit at the top with a person icon. Components form the value chain below them, connected by dependency edges.

Strategic Lens: Climat / Doctrine / Manoeuvre

Every strategic element on a map operates at one of three levels:

  • Climat — External forces you cannot control: evolution toward commodity, network effects, co-evolution. Expressed as signal annotations. Read the climate; do not fight it.
  • Doctrine — Universal principles you choose to follow: hygiene, context awareness, operational excellence. Expressed via the doctrine: metadata field.
  • Manoeuvre — Deliberate, context-dependent actions to change your position on the map. Expressed as gameplay annotations. A manoeuvre repositions you on the map (changes the terrain); a tactic optimizes within the current position (does the same thing better). Only manoeuvres belong as gameplay — refactoring code is a tactic; replacing a legacy system via strangler-fig is a manoeuvre.

Workflow

Follow this end-to-end process every time:

1. Analyze the request

Identify from the user's description:

  • Anchors — who are the users/actors?
  • Components — what capabilities, systems, or resources exist?
  • Dependencies — what depends on what? Build the value chain top-down.
  • Evolution — where does each component sit on the maturity axis?

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.
