Phase 1: Identify Balance Domain

Determine the balance domain from $ARGUMENTS[0]:

• Combat → weapon/ability DPS, time-to-kill, damage type interactions
• Economy → resource faucets/sinks, acquisition rates, item pricing
• Progression → XP/power curves, dead zones, power spikes
• Loot → rarity distribution, pity timers, inventory pressure
• File path given → load that file directly and infer domain from content

If no argument, ask the user which system to check.

Phase 2: Read Data Files

Read relevant files from assets/data/ and design/balance/ for the identified domain. Note every file read — they will appear in the Data Sources section of the report.

Phase 3: Read Design Document

Read the GDD for the system from design/gdd/ to understand intended design targets, tuning knobs, and expected value ranges. This is the baseline for "correct" behaviour.

Phase 4: Perform Analysis

Run domain-specific checks:

Combat balance:

• Calculate DPS for all weapons/abilities at each power tier
• Check time-to-kill at each tier
• Identify any options that dominate all others (strictly better)
• Check if defensive options can create unkillable states
• Verify damage type/resistance interactions are balanced

Economy balance:

• Map all resource faucets and sinks with flow rates
• Project resource accumulation over time
• Check for infinite resource loops
• Verify gold sinks scale with gold generation
• Check if any items are never worth purchasing

Progression balance:

• Plot the XP curve and power curve
• Check for dead zones (no meaningful progression for too long)
• Check for power spikes (sudden jumps in capability)
• Verify content gates align with expected player power
• Check if skip/grind strategies break intended pacing

Loot balance:

• Calculate expected time to acquire each rarity tier
• Check pity timer math
• Verify no loot is strictly useless at any stage
• Check inventory pressure vs acquisition rate

Phase 6: Fix & Verify Cycle

After presenting the report, ask:

> "Would you like to fix any of these balance issues now?"

If yes:

• Ask which issue to address first (refer to the Recommendations table by priority row)
• Guide the user to update the relevant data file in assets/data/ or formula in design/balance/
• After each fix, offer to re-run the relevant balance checks to verify no new outliers were introduced
• If the fix changes a tuning knob defined in a GDD or referenced by an ADR, remind the user:

> "This value is defined in a design document. Run /propagate-design-change [path] on the affected GDD to find downstream impacts before committing."

If no:

• Summarize open issues and suggest saving the report to design/balance/balance-check-[system]-[date].md for later

End with: > "Re-run /balance-check after fixes to verify."
