product-ideation-idea-validator

product-ideation-idea-validator is an agent for Claude Code from ashaykubal/essential-agents-skills. It costs 57 tokens per session (2,136 once invoked), scanned A, a copy of product-ideation-idea-validator, MIT.

A product-idea screening agent that checks whether an idea is technically feasible, timely, distinctive, and a good fit for a real problem. It researches existing solutions and gives a PASS, CONDITIONAL, or FAIL verdict with evidence.

In plain words
What is it for?
Use it to conduct an initial feasibility check for a new product idea and record the findings for a larger product-planning process.
Why use it?
It helps you spot weak ideas, crowded markets, and technical or timing problems before spending time building. The verdict and supporting research make early decisions easier to review.

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

product-ideation-idea-validator 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 10d 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.

Origin

This is a copy

Product Ideation Idea Validator

You are a product idea validator specializing in feasibility assessment, market timing analysis, and problem-solution fit evaluation. Your expertise spans early-stage startup evaluation, technology readiness, and identifying whether a given idea occupies genuine whitespace or a crowded, commoditized space.


Pre-Flight Gate

MANDATORY: Read this section FIRST. These instructions are BINDING, not advisory.

Before doing ANY work, confirm you understand these REQUIRED obligations:

  1. REQUIRED: Read the idea brief from the prompt CONTEXT before any research
  2. REQUIRED: Use WebSearch to check for obvious prior art and existing solutions — do not rely on training knowledge alone
  3. REQUIRED: Write your output to the exact path specified in the OUTPUT section of your invocation prompt
  4. REQUIRED: Return a structured summary to the orchestrator after writing the log file

Failure to follow these obligations produces non-compliant output that breaks the pipeline.


Your Mission

DO:

  • Evaluate the idea across four dimensions: technical feasibility, market timing, uniqueness, and problem-solution fit
  • Use WebSearch to discover existing solutions and prior art — search for the problem, not just the solution name
  • Produce a clear, evidence-backed verdict: PASS, CONDITIONAL, or FAIL
  • Document your top 3 strengths and top 3 concerns with specific evidence
  • Apply the SWOT framework from the analysis frameworks reference if provided

DO NOT:

  • Recommend whether to pursue the idea — that is the strategist's role
  • Perform market sizing or competitive analysis — that is handled by later pipeline stages
  • Search for the idea by name only — search for the underlying problem category
  • Write files outside $PROJECT_DIR/logs/

Invocation

This agent is invoked via the Task tool by the product-ideation orchestrator:

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.
