idea-validator

idea-validator is a skill for Claude Code, Codex from aakashg/pm-claude-skills. It costs 59 tokens per session (2,147 once invoked), scanned A, original, MIT.

A framework for testing whether a product idea is worth building by examining it across five areas and giving a GO, ITERATE, or STOP conclusion.

In plain words
What is it for?
Use it to assess a new product concept, review competitors and customer behavior, and decide whether to build it, revise it, or stop.
Why use it?
It separates evidence from enthusiasm and makes clear when an idea is only a hypothesis because supporting research or user evidence is missing.

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

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 11d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Idea Validator

Stress-test a product idea across 5 dimensions and return a GO / ITERATE / STOP verdict with evidence.

Step 0 — Read first

Source Path What to extract
Project context CLAUDE.md Company, market, target users, current focus
Scoring rubric references/scoring-rubric.md Strong/Moderate/Weak bar for each dimension
User's materials any doc, deck, or notes they name Actual customer quotes, usage data, pricing research
Existing research docs/, research/ if present Prior validation on the same problem

If the user names no materials, say so explicitly in the verdict. An idea validated only against your training data is a hypothesis, not a validation, and you must label it that way.

Constraints

Mandatory. These override the user's enthusiasm.

  • Every rating requires 3–5 sentences of specific reasoning. A rating with no evidence is invalid.
  • Never rate STRONG without a named comparable, a number, or a cited user behavior.
  • Never default to GO because the user is excited. Honesty is the deliverable.
  • Never treat "no competitors" as opportunity. It usually means no market. Say so.
  • Never recommend "build the MVP" as the first next step.
  • Flag every guess with ASSUMPTION: and name the data that would confirm or deny it.
  • Flag every missing input with [NEED: X].
  • Never give all five STRONGs unless the evidence is genuinely exceptional. Most ideas are a mix.
  • Name what is hard and why. "This could be challenging" is not a risk.

Existence check

Before scoring anything, verify three things:

  1. Problem — a specific pain, stated in the user's own words, with a frequency.
  2. User — a named segment: job title, company size, situation. "Everyone" and "businesses" fail this check.
  3. Evidence — one real signal: a customer quote, a support ticket volume, a competitor's pricing page, a workaround they observed.

If two of three are missing, refuse to score. Say which are missing and ask for exactly those. Scoring an idea with no user and no evidence produces a confident number built on nothing, which is worse than no analysis.

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.
