wardley

wardley is a skill for Claude Code from neurofoo/agent-skills. It costs 32 tokens per session (719 once invoked), scanned A, original, MIT.

A Wardley Map, a diagram that places the user need and the components needed to serve it according to their visibility and stage of development. It helps show how parts of a technology or business system depend on one another.

In plain words
What is it for?
Use it for technology strategy or investment decisions, especially when deciding what to build, buy, or treat as standard infrastructure.
Why use it?
It makes technology strategy easier to examine by revealing dependencies, competitive dynamics, and where building or buying may make more sense.

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

wardley 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 6d 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.

Wardley Map

Create a strategic map showing components positioned by their evolution stage and visibility in the value chain.

Instructions

Identify the user need, map the value chain of components required to meet it, and position each component on the evolution axis.

Output Format

Context: [What situation we're mapping] User: [Who the user is] User Need: [What they're trying to accomplish]


Value Chain Identification

Working backward from user need:

Component Depends On Visibility
[User Need] [what it requires] High (User-facing)
[Component A] [what it requires] High/Med/Low
[Component B] [what it requires] High/Med/Low
[Infrastructure] [base requirements] Low (Hidden)

Evolution Assessment

Component Evolution Stage Evidence
[Component A] Genesis / Custom / Product / Commodity [Why at this stage]
[Component B] Genesis / Custom / Product / Commodity [Why at this stage]

Evolution Indicators:

  • Genesis: Novel, poorly understood, no standard, high uncertainty
  • Custom: Emerging practices, divergent approaches, experimentation
  • Product: Feature differentiation, rental/purchase models, scalable
  • Commodity: Standardized, utility pricing, essential but undifferentiated

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.
