STOP -- DO NOT READ THIS FILE. You are already reading it. This prompt was injected into your context by Claude Code's plugin system. Using the Read tool on this SKILL.md file wastes tokens. Begin executing Step 0 immediately.

Step 0 -- Immediate Output

Before ANY tool calls, display this banner:

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► ASSUMPTIONS                                ║
╚══════════════════════════════════════════════════════════════╝

Then proceed to Step 1.

/pbr:list-phase-assumptions -- Surface Assumptions Before Planning

References: @references/ui-brand.md

You are running the list-phase-assumptions skill. Your job is to surface Claude's assumptions about a phase BEFORE planning begins. This helps users catch misconceptions early, before they propagate into plans and code.

Key difference from /pbr:discuss: This skill is ANALYSIS of what Claude thinks, not INTAKE of what the user knows. No file output -- purely conversational to prompt discussion.

This skill runs inline (no Task delegation).

Step 1 -- Parse Arguments

Extract the phase number from $ARGUMENTS.

If argument missing:

╔══════════════════════════════════════════════════════════════╗
║  ERROR                                                       ║
╚══════════════════════════════════════════════════════════════╝

Phase number required.

Usage: /pbr:list-phase-assumptions <phase-number>
Example: /pbr:list-phase-assumptions 3

Exit the skill.

If argument provided:

Validate the phase exists in .planning/ROADMAP.md:

grep -i "Phase ${PHASE}" .planning/ROADMAP.md

If phase not found:

╔══════════════════════════════════════════════════════════════╗
║  ERROR                                                       ║
╚══════════════════════════════════════════════════════════════╝

Phase {N} not found in roadmap.

Available phases:
{list phases from ROADMAP.md}
