websocket-toolkit-googleai-dart
Automates updating googleai_dart when Gemini Live API WebSocket schema changes. Fetches latest schema, compares against current, generates changelogs and prioritized implementation plans. Use for: (1) Checking for Live API updates, (2) Generating implementation plans for WebSocket changes, (3) Creating new message types from schema, (4) Syncing local schema with upstream. Triggers: "update live api", "sync websocket", "new messages", "live api changes", "check for live updates", "update live schema", "websocket version", "fetch live schema", "compare live schema", "what changed in live api", "live implementation plan".
When & Why to Use This Skill
The WebSocket Toolkit for googleai_dart is a specialized automation suite designed to synchronize Dart-based AI integrations with the latest Gemini Live API WebSocket schemas. It streamlines the maintenance lifecycle by fetching remote schemas, analyzing structural changes, and generating prioritized implementation plans. By providing standardized Dart templates and rigorous multi-pass verification scripts, it ensures high-quality, type-safe implementations for real-time audio, video, and text streaming features.
Use Cases
- Automating the detection of breaking changes or new features in the Gemini Live API WebSocket schema.
- Generating structured implementation plans and human-readable changelogs to guide developers through API migrations.
- Accelerating Dart development using pre-defined templates for sealed message classes, models, and unit tests.
- Ensuring package integrity through automated export verification, documentation checks, and property-level model validation.
- Maintaining synchronization between local schema definitions and upstream Google AI/Vertex AI WebSocket endpoints.

WebSocket Toolkit (googleai_dart)
Uses shared scripts from websocket-toolkit with googleai_dart-specific configuration.
Uses verification scripts from openapi-toolkit.
Prerequisites
GEMINI_API_KEYorGOOGLE_AI_API_KEYenvironment variable set- Working directory: Repository root
- Python 3

Gemini Live API (real-time audio/video/text streaming) | Yes |
Workflow
1. Fetch Latest Schema
python3 .claude/shared/websocket-toolkit/scripts/fetch_schema.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
Output: /tmp/websocket-toolkit-googleai-dart/latest-live.json
2. Analyze Changes
python3 .claude/shared/websocket-toolkit/scripts/analyze_changes.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config \
packages/googleai_dart/specs/live-api-schema.json /tmp/websocket-toolkit-googleai-dart/latest-live.json \
--format all \
--changelog-out /tmp/websocket-toolkit-googleai-dart/changelog-live.md \
--plan-out /tmp/websocket-toolkit-googleai-dart/plan-live.md
Generates:
changelog-live.md- Human-readable change summaryplan-live.md- Prioritized implementation plan (P0-P4)
3. Implement Changes
Before implementing, read references/implementation-patterns.md for:
- Sealed class structure for messages
- WebSocket connection patterns
- JSON serialization for WebSocket messages
Use templates from ../../shared/websocket-toolkit/assets/:
sealed_message_template.dart- Sealed class for WebSocket messagesmodel_template.dart- Model class structuretest_template.dart- Unit test structure
3.5 Update Documentation (MANDATORY)
Before running the review checklist:
- README.md - Add/update Live API section
- example/ - Create/update
live_example.dart - CHANGELOG.md - Add entry for new features
4. Review & Validate (MANDATORY)
# Pass 2: Barrel file verification (from shared/openapi-toolkit)
python3 .claude/shared/openapi-toolkit/scripts/verify_exports.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
# Pass 3: Documentation completeness
python3 .claude/shared/openapi-toolkit/scripts/verify_readme.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
python3 .claude/shared/openapi-toolkit/scripts/verify_examples.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
python3 .claude/shared/openapi-toolkit/scripts/verify_readme_code.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
# Pass 4: Property-level verification
python3 .claude/shared/openapi-toolkit/scripts/verify_model_properties.py \
--config-dir .claude/skills/websocket-toolkit-googleai-dart/config
# Dart quality checks (run from packages/googleai_dart)
cd packages/googleai_dart && dart analyze --fatal-infos && dart format --set-exit-if-changed . && dart test test/unit/
5. Testing (MANDATORY)
Test locations:
- Config classes:
test/unit/models/live/config/ - Message types:
test/unit/models/live/messages/ - Enums:
test/unit/models/live/enums/
cd packages/googleai_dart && dart test test/unit/models/live/
6. Finalize
cp /tmp/websocket-toolkit-googleai-dart/latest-live.json packages/googleai_dart/specs/live-api-schema.json
cd packages/googleai_dart && dart test && dart analyze && dart format --set-exit-if-changed .
