Warhammer 40k Build Army List

Confirm all inputs before proceeding.

Step 2: Load Faction Data

DETERMINISTIC — no memory allowed.

1. Use warhammer-40k-army-data to read _bmad/_config/custom/warhammer-40k/data/datasheets/{faction}.compact.json
2. If cheatsheet exists: read army-lists/{faction}/*.cheatsheet.json for reference lists
3. Read _bmad-output/warhammer-40k/agents/tacticus-sidecar/validation-rules.yaml for detachment rules and hard rules
4. Check _bmad-output/warhammer-40k/shared/hallucination-registry.yaml for faction-specific patterns

If any data file is missing, inform the user and offer to web search for current data.

Step 3: Build 2000pt List First

MANDATORY ORDER: Always build 2000pt first, then scale down.

1. Select units from datasheet data — cite points from the file
2. Show math for every selection: "X models x Ypts = Zpts [Source: {faction}.compact.json]"
3. Assign leaders to bodyguard units — verify leads array in datasheet
4. Assign enhancements — verify eligibility (no Epic Heroes, check detachment rules)
5. Running total after each unit added

Step 4: Run Validation Gates

USE warhammer-40k-validate-list skill — do NOT validate from memory.

Run all 7 gates. If any fail, fix before proceeding:

1. Points Total (hard cap)
2. Rule of Three
3. Epic Hero Uniqueness
4. Enhancement Eligibility
5. Unit Sizes
6. Leader Attachments
7. Faction Abilities warnings

Step 5: Scale Down

Create 1000pt and 500pt variants by removing units proportionally:

• 1000pt: remove ~half the army, keep core synergies
• 500pt: keep only essential units, max 1 enhancement
• Re-run validation gates for each size

Step 6: Model Assembly Guide

MANDATORY — every list must include this.

For each points level, create:

Then add:

• Shopping List Summary with GW product names (verify via web search, mark [UNVERIFIED] if from memory)
• Total Model Count per points level
• Magnetization Recommendations for multi-loadout units

Step 7: Save

Save the completed list to _bmad-output/warhammer-40k/agents/tacticus-sidecar/lists.md and offer to create a cheatsheet JSON.

Anti-Hallucination Checkpoints

At each step, verify:

• All points come from datasheet files, not memory
• All wargear exists in the unit's datasheet weapons array
• No Epic Heroes have enhancements
• Leader attachments verified against leads array
• Math shown and verified by re-adding
• Sources cited for every factual claim
