Glb Web Handoff

glb-web-handoff

Purpose

Define reliable handoff language and checks for GLB/web scenarios without overclaiming.

Quick start

• confirm this skill fits your goal
• provide required inputs first
• keep runtime claims evidence-bound
• follow suggested next-skill handoff

When to use

• before web handoff summary
• when user asks GLB readiness
• when preparing Three.js/R3F expectations

When not to use

• to claim GLB was produced without evidence
• to replace runtime export verification

Trigger phrases

• "prepare web handoff"
• "is GLB ready"
• "summarize export status"

Prerequisites / readiness

• quality checker output available
• artifact evidence state known
• runtime mode known

Input schema

Required inputs

• artifact status evidence
• handoff target context
• known compatibility assumptions

Optional inputs

• size/performance constraints
• expected downstream stack details

Assumptions to confirm

• transform/scale/origin assumptions
• texture/material portability assumptions
• loader/extension assumptions

Output schema

Primary output

• handoff status report

Secondary output

• compatibility assumptions and caveats

Evidence / caveat output

• explicit artifact status per artifact
• unresolved risk notes and next checks

Required laws

• ../../laws/evidence-before-done.md
• ../../laws/official-runtime-only.md
• ../../laws/non-blender-user-language.md
• ../../laws/no-arbitrary-python-interface.md

Official runtime boundary

No GLB/export success claim without concrete evidence.

Operating procedure

1. Enumerate expected handoff artifacts (GLB/preview/report).
2. Mark each artifact status (Produced/Not Produced/Not Run).
3. Validate transform/scale/origin assumptions are documented.
4. Validate material/texture caveats are documented.
5. Record Three.js/R3F compatibility assumptions.
6. Record performance caveats and uncertainty.
7. Check evidence boundary compliance.
8. Produce handoff summary and next actions.

Decision tree

• If GLB evidence exists → report produced + caveats.
• If no GLB evidence and runtime not run → Not Run status.
• If runtime run but export failed → Not Produced + failure note.

Playbooks

• Playbook A: text-only planning path
• Playbook B: runtime-ready path with evidence gating
• Playbook C: blocked runtime path with caveat-first reporting

Mode handling

Text-only mode

• handoff expectations only
• artifacts marked Not Run/Not Produced

Runtime-ready mode

• include evidence-linked artifact statuses

Blocked runtime mode

• no production claims
• blocker-driven next steps

Validation checklist

• [ ] GLB status explicit
• [ ] preview status explicit
• [ ] transform/scale/origin assumptions documented
• [ ] material/texture caveats documented
• [ ] stack assumptions documented
• [ ] performance caveats documented
• [ ] evidence boundary respected
• [ ] next checks actionable
• [ ] no unsupported readiness claims
• [ ] plain-language handoff summary

Pass / Warn / Fail rubric

| Category | Pass | Warn | Fail | |---|---|---|---| | Artifact truth | Status matches evidence | Partial evidence | Claims without evidence | | Compatibility clarity | Assumptions/caveats complete | Some gaps | Missing assumptions | | Web handoff usability | Clear next actions | Partial actionability | Confusing or incomplete | | Evidence boundary | No overclaims | Minor ambiguity | Contradictory claims |

Failure handling

• Missing evidence: mark Not Run/Not Produced and list missing checks.
• Failed export evidence: record failure reason and retry path.
• Unknown compatibility: keep Warn with explicit caveat.

Troubleshooting

• Existing files found: verify provenance before claiming produced.
• Missing scale/origin assumptions: add as blocker.
• Missing stack assumptions: mark handoff as conditional.

Best practices

• always pair artifact status with caveat
• separate assumptions from verified facts
• prioritize non-technical clarity in final handoff text

Good examples

“GLB status: Not Run (runtime not executed in this pass). Next: run official runtime eval and capture export evidence.”

Bad examples

“GLB is ready for production.” (no artifact proof)

User-facing response template

• What is included now
• What is still unverified
• What to run/check next

Anti-patterns

• skipping required laws or runtime boundary statements
• claiming runtime/artifact success without evidence
• using non-official runtime setup paths
• producing jargon-heavy final output without explanation

Cross-skill handoff

• Next: non-blender-user-response-writer

Non-goals

• runtime export code generation
• unsupported compatibility guarantees
