name: product-spec-generator description: This prompt instructs the AI to produce a structured feature specification document for a proposed product feature, using provided inputs such as target users, key functionalities, technical considerations, and estimated development effort. The resulting output is a clear, implementation-ready spec organized into standard product and engineering sections—overview, goals with success metrics, user stories, acceptance criteria mapped to those stories, a high-level technical design, and future considerations—so developers can begin building with aligned requirements and scope. compatibility: Requires betterprompt >= 0.1.3 metadata: openclaw: homepage: https://github.com/BetterPromptme/skills emoji: 🧩 requires: anyBins: - betterprompt - bp os: - linux - darwin install: - id: node kind: node package: betterprompt bins: [betterprompt, bp] label: Install BetterPrompt CLI (node)

What it does

This prompt instructs the AI to produce a structured feature specification document for a proposed product feature, using provided inputs such as target users, key functionalities, technical considerations, and estimated development effort. The resulting output is a clear, implementation-ready spec organized into standard product and engineering sections—overview, goals with success metrics, user stories, acceptance criteria mapped to those stories, a high-level technical design, and future considerations—so developers can begin building with aligned requirements and scope.

Inputs

textInputs

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

Variable key	Required?	Description	Defaults
feature_idea	Optional		Shared Notes
target_users	Optional		Remote workers
development_effort	Optional		30
key_functionalities	Optional		Track expenses and split bills with roommates
technical_considerations	Optional		Web app, real-time updates

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):
  • feature_idea (default: Shared Notes)
  • target_users (default: Remote workers)
  • development_effort (default: 30)
  • key_functionalities (default: Track expenses and split bills with roommates)
  • technical_considerations (default: Web app, real-time updates)
• Optional: model and options.
  • Present the human with the default model gpt-4.1-mini and its available options. Look up gpt-4.1-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: {}.
  • If the human does not specify, defaults are used: model gpt-4.1-mini, options {}. 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 product-spec-generator).

Command form:

betterprompt generate product-spec-generator \
  [--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-4.1-mini.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• 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 product-spec-generator \
  --input 'feature_idea=Shared Notes' \
  --input 'target_users=Remote workers' \
  --input development_effort=30 \
  --input 'key_functionalities=Track expenses and split bills with roommates' \
  --input 'technical_considerations=Web app, real-time updates' \
  --model gpt-4.1-mini \
  --options '{}'
