Asset Style Consistency Checker

asset-style-consistency-checker

Purpose

Catch style mismatches between assets before they end up in the same scene where the inconsistency reads as compositing error.

Quick start

• list every asset planned for the scene
• evaluate each on style axes (realism / detail / color / surface)
• flag drift between assets
• recommend remediation (drop / restyle / replace)

When to use

• after asset-license-checker clears the assets
• before scene build
• when a scene preview shows visible style mismatch
• when assets come from multiple sources

When not to use

• single asset (no consistency check needed)
• pure planning before assets are picked
• intentionally mixed-style art direction (verify with brief)

Trigger phrases

• "do these assets fit together"
• "style check the assets"
• "scene feels like a collage"

Prerequisites / readiness

• asset list with previews known
• scene brief style locked
• target scene quality bar set

Input schema

Required inputs

| Input | Why it is required | |---|---| | Asset list with previews | Subject of the check | | Brief style locked | Reference for consistency |

Optional inputs

| Input | Use | |---|---| | Reference image / mood board | Style baseline | | Existing scene preview | Real-world consistency check |

Assumptions to confirm

• Brief style is unambiguous.
• Asset previews are representative of final use.

Output schema

Primary output

A per-asset row table: name, realism axis, detail axis, color axis, surface axis, drift verdict (None / Minor / Major), remediation note.

Secondary output

• top-line consistency verdict
• assets to drop / restyle / replace
• evidence label

Evidence / caveat output

Official runtime boundary

Validation skill — does not modify assets. Verdicts are based on documented previews + style brief.

Operating procedure

1. Read asset list and previews.
2. Read brief style.
3. For each asset, evaluate on 4 style axes (see references/style-axes.md).
4. Compare against brief baseline; flag drift.
5. List remediation options.
6. Hand off to scene build (Pass) or asset-fallback-strategy (Fail).

Decision tree

Asset matches all 4 axes?
  → Pass row
Asset off on 1 axis?
  → Minor drift; verify intent
Asset off on 2+ axes?
  → Major drift; recommend replace
Two assets in same scene with major drift between them?
  → Fail; cannot mix without breaking visual hierarchy

Playbooks

Playbook A: All-realistic product hero

All assets realistic; same detail density; PBR materials. One stylized prop → drop or restyle.

Playbook B: Stylized character + flat background

Character is stylized; background must be equally simplified. Detailed background asset → drop.

Playbook C: Mixed-style intentional (collage / editorial)

Brief explicitly mixed-style; verify with brief; drift becomes feature, not bug.

Mode handling

Text-only mode

Verdicts based on documented previews.

Runtime-ready mode

Verdicts based on actual scene preview snapshot.

Blocked runtime mode

Skip rows that depend on rendered preview; mark as such.

Validation checklist

• [ ] Every asset has 4-axis row
• [ ] Brief baseline cited
• [ ] Drift verdict per row
• [ ] Top-line consistency verdict
• [ ] Remediation for any drift
• [ ] Honest evidence label

Pass / Warn / Fail rubric

| Verdict | Criteria | |---|---| | Pass | All assets within consistency tolerance; brief style respected. | | Warn | One asset minor drift; remediation noted. | | Fail | Two+ assets major drift; brief style not respected; collage-error visible. |

Failure handling

• Major drift → recommend asset replacement; hand off to discovery.
• Brief unclear about style → hand off to brief writer.
• "Mixed style is intentional" → verify with user before accepting.

Troubleshooting

| Problem | Response | |---|---| | Hard to tell style from preview | Need higher-quality reference; mark Warn until clarified. | | Style is on the boundary | Lock the style axis early; do not invite repeat boundary calls. | | User changes style mid-scene | Treat as scope creep; hand off to scope enforcer. |

Best practices

• Lock style early; revisions are cheap pre-build.
• Always evaluate against the brief, not against vibe.
• Prefer 1 source for related assets to reduce drift risk.
• Keep this skill narrow — do not check license / budget / topology here.

Good examples

• "shoe-base.glb: realistic, high-detail, neutral color, PBR. shoe-laces.glb: realistic, high-detail, neutral, PBR. shoe-environment-stylized.glb: stylized, low-detail, saturated, flat. Drift: Major. Remediation: replace stylized environment."

Bad examples

• "Assets look like they go together." — no axis-by-axis verdict.

User-facing response template

Brief style: 

| Asset | Realism | Detail | Color | Surface | Drift | Remediation |
|---|---|---|---|---|---|---|

Top-line consistency: Pass / Warn / Fail
Assets to drop / restyle / replace: 
Limitations: 
Next: scene build (Pass) / asset-fallback-strategy (Fail)

Anti-patterns

• "Vibe match" verdicts.
• Skipping the brief reference.
• Mixing license / budget / topology checks here.
• Inventing axis values.
