Second Brain PRD Generator

Generate a personalized Product Requirements Document for building an AI Second Brain, based on the user's completed requirements template.

A blank template is bundled with this skill at ${CLAUDE_SKILL_DIR}/my-second-brain-requirements.md. Copy it to your workspace and fill it out before running this skill.

Parameters

• $0 (required) — Path to the filled-out requirements file (e.g., ./my-second-brain-requirements.md)
• $1 (optional) — Output path for the PRD. Defaults to .agent/plans/second-brain-prd.md

Workflow

1. Read the requirements — Read the filled-out requirements file at $0. If no argument was provided, ask the user for the path. If they haven't filled one out yet, tell them a blank template is available at ${CLAUDE_SKILL_DIR}/my-second-brain-requirements.md — they should copy it to their workspace and fill it out first.

2. Load the architecture reference — Read ${CLAUDE_SKILL_DIR}/references/architecture-reference.md for the blueprint.

3. Research ALL tools and APIs — Do not assume familiarity with any platform or library. Even common APIs like Gmail or Slack have nuances, rate limits, and SDK-specific patterns that matter for implementation. For every tool in the user's stack, do web research to ensure the PRD contains accurate, specific guidance.
