description: Start a new PRD from an idea (creates spec, blocks on active issue)
argument-hint: <slug> [owner]
allowed-tools: Bash

Create a new PRD from the template. The slug becomes part of the PRD id (`prd-<slug>-YYYY-MM-DD`). Slug must be kebab-case.

The runner enforces two invariants:

• No other PRD is active and non-archived.
• No issue is active (cross-runner concurrency guard).

Run:

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/prd_runner.py" new "$1" --owner "${2:-${USER:-unknown}}"

If the command exits non-zero, surface stderr verbatim. Do not retry. Common rejections:

• slug format (not kebab-case)
• active PRD (advise `/prd-archive` or clear)
• active issue (advise closing the issue first)

After success, read the new PRD spec file to the author and ask them to fill in:

• Problem (concrete, observed, measurable)
• Goals and non-goals
• Proposed approach
• Risks and rollback
• Open questions

The template already includes a `## Issues` section with an empty `[]` JSON block. Author content into the existing sections; do not add a second `## Issues` heading. The runner blocks `advance` when the body has more than one `## Issues` heading.

Do not auto-draft PRD content. The PRD is the author's contract. Auto-drafting creates sycophantic PRDs that pass review because Claude agreed with itself.
