invent

invent is a command for Claude Code from robisson/build-like-amazon-agent-skills. It costs 0 tokens per session (357 once invoked), scanned A, original, MIT.

A Working Backwards exercise for designing the simplest solution to a customer's problem. Working Backwards is a product-planning method that starts with the desired customer experience before deciding how to build it.

In plain words
What is it for?
Use it to describe the ideal experience, compare possible approaches, select a simple direction, map the customer workflow, and document required capabilities and exclusions.
Why use it?
It turns an unclear product idea into a concrete solution outline, while making non-goals, risks, and unanswered questions visible. It keeps planning focused on customer needs rather than implementation details.

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

invent 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.

What it actually says

Invent — What Is the Solution?

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.

You are activating the wb-invent skill. This is Phase 3 of Working Backwards: inventing the simplest solution that solves the customer's problem.

What to do

  1. Read the skill file at skills/wb-invent/ for full context.
  2. Review the customer profile and problem statement from previous phases.
  3. Guide the user through solution ideation:
    • What is the ideal customer experience? (describe the end state)
    • What are 3 possible approaches? (brainstorm before converging)
    • Which approach is simplest while fully solving the problem?
    • What would the customer's new workflow look like step-by-step?
  4. Write a Solution Sketch with:
    • Elevator pitch (2-3 sentences max)
    • Customer experience walkthrough (narrative form)
    • Key capabilities required
    • What we're explicitly NOT building (anti-scope)
    • Open questions and risks

Key Principles

  • Start with the customer experience, not the architecture.
  • Simplify ruthlessly — if a feature doesn't serve the core problem, cut it.
  • "What would have to be true?" — identify assumptions to validate.
  • Prefer reversible decisions; avoid one-way doors when possible.
  • Think big, start small, launch fast.

Output

Save to docs/working-backwards/<feature-name>/solution-sketch.md.

Ask: "Would you like to proceed to /refine (PR/FAQ writing)?"

Changes

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.

invent is a command published in the GitHub repository robisson/build-like-amazon-agent-skills (14 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 357 tokens. 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 2026-08-30.
