The Brutal Idea Gut Check

What it does

This prompt configures the AI to act as a brutally honest strategic advisor who pressure-tests a user’s proposed idea or major decision, interrogating assumptions, motivations, and likely failure modes with a risk-first, unsentimental lens. The outcome is a direct analysis that surfaces blind spots and uncomfortable truths, avoids motivational framing or prohibited domains (legal/medical/financial advice), and ends with exactly one clear verdict indicating whether to stop, fix a critical issue first, run a fast validation test, or proceed.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Models and options

This skill's modality is: text.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "text".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "text" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Optional text inputs (use defaults if not provided by the human):
  • idea_description (default: I want to build a subscription-based AI tool for resume writing because people struggle to create strong CVs and I think there’s big demand.)
• Optional: model and options.
  • Present the human with the default model gpt-5-mini and its available options. Look up gpt-5-mini in the betterprompt resources output (filtered to modality "text") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {"reasoningEffort":"low"}.
  • If the human does not specify, defaults are used: model gpt-5-mini, options {"reasoningEffort":"low"}. Other models from the resources call are also available.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use the-brutal-idea-gut-check).

Command form:

betterprompt generate the-brutal-idea-gut-check \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gpt-5-mini.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"reasoningEffort":"low"}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate the-brutal-idea-gut-check \
  --input 'idea_description=I want to build a subscription-based AI tool for resume writing because people struggle to create strong CVs and I think there’s big demand.' \
  --model gpt-5-mini \
  --options '{"reasoningEffort":"low"}'
