wb

wb is a command for Claude Code from robisson/build-like-amazon-agent-skills. It costs 0 tokens per session (539 once invoked), scanned A, original, MIT.

A guided process for developing a product idea from the customer problem to a proposed solution and a PR/FAQ document, with human approval after each stage.

In plain words
What is it for?
Running the Working Backwards method: identifying customers, defining the problem, shaping a solution, writing the PR/FAQ, and planning validation.
Why use it?
It keeps product discovery structured and prevents later decisions from being made before earlier assumptions have been reviewed.

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

wb 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.

How it starts

The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working Backwards — Start Here

Path resolution: All skills/, agents/, and patterns/ paths in this command are relative to the plugin root directory. If not found in the working directory, resolve from the plugin installation path.

IMPORTANT: Each WB stage has a mandatory human approval gate. After completing each stage, present your work and ask the user to review before proceeding. Never skip stages or rush to PR/FAQ. The PR/FAQ is Stage 4 — it requires Stages 1-3 to be completed and individually approved first.

You are activating the Working Backwards meta-skill. This is Amazon's product discovery process: start from the customer and work backwards to the solution.

What to do

  1. Read the skill file at skills/working-backwards/ for full context.
  2. Ask the user: "What product or feature are you thinking about?"
  3. Based on their answer, guide them through the five WB phases in order:
    • Listen → Who is the customer? What do they need?
    • Define → What is the specific problem we're solving?
    • Invent → What is our proposed solution?
    • Refine → Write the PR/FAQ document.
    • Test → How will we validate and measure success?
  4. After each phase, STOP. Present the full output to the user. Ask them to review and approve before moving to the next phase. Do NOT proceed without explicit user confirmation.
  5. For each phase, load the corresponding skill from skills/wb-*.
  6. Produce artifacts in docs/working-backwards/ — customer profiles, problem statements, solution sketches, and the final PR/FAQ.

Approval Gates (Non-Negotiable)

After completing each stage, present your output and ask: "Here's what I have for [Stage]. Does this look right? Anything to adjust before we move to [Next Stage]?" Wait for explicit approval. If the user asks for changes, revise and re-present. Only proceed after they confirm.

Key Principles

  • Customer obsession: every decision traces back to a customer need.
  • Write the press release BEFORE writing code.
  • If you can't write a clear FAQ answer, the idea isn't ready.
  • Iterate: it's normal to loop between phases multiple times.

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.
