Pixi Svelte Integrator

Use this skill to build stable Pixi+Svelte integrations with explicit lifecycle and teardown guarantees.

Workflow

1. Define integration boundaries first.

• Decide ownership of app state, render loop control, and event dispatch.
• Keep Pixi scene mutation behind a clear adapter layer.

2. Wire lifecycle safely.

• Create Pixi Application in Svelte mount lifecycle.
• Bind canvas to a dedicated host element.
• Destroy application and detach listeners on unmount.

3. Handle resize and DPI policy.

• Track container size updates and renderer resize calls.
• Set and document resolution policy for high-DPI screens.

4. Validate event and render flow.

• Ensure input/event bridge is deterministic and unsubscribed on teardown.
• Keep animation tick subscriptions bounded and removable.

5. Run contract checks before handoff.

• Validate lifecycle contract (create/mount/resize/unmount) and required artifacts.
• Treat missing destroy/unsubscribe paths as blockers.

Commands

python3 scripts/validate_pixi_svelte_contract.py \
  --contract <path/to/pixi_svelte_contract.json>

Treat non-zero exits as blocker findings.

Output Contract

Return:

1. Integration Map: host component, Pixi app adapter, and event bridge.
2. Validation Findings: pass/fail checks for lifecycle, resize, and teardown.
3. Patch Plan: exact files and integration points to change.
4. Verification: commands and expected pass criteria.
5. Residual Risks: unresolved runtime synchronization concerns.

• references/signoff-template.md: handoff template for release readiness.

Execution Rules

• Keep Pixi init/destroy aligned with Svelte mount/unmount.
• Keep all event subscriptions disposable and verified at teardown.
• Avoid direct scene mutation from arbitrary Svelte components.
• Flag any leaked ticker/listener path as a blocker.
