name: openapi-toolkit-googleai-dart description: Automates updating googleai_dart when Google AI OpenAPI spec changes. Fetches latest spec, compares against current, generates changelogs and prioritized implementation plans. Use for: (1) Checking for API updates, (2) Generating implementation plans for spec changes, (3) Creating new models/endpoints from spec, (4) Syncing local spec with upstream. Triggers: "update api", "sync openapi", "new endpoints", "api changes", "check for updates", "update spec", "api version", "fetch spec", "compare spec", "what changed in the api", "implementation plan".

OpenAPI Toolkit (googleai_dart)

Uses shared scripts from openapi-toolkit with googleai_dart-specific configuration.

Prerequisites

• GEMINI_API_KEY or GOOGLE_AI_API_KEY environment variable set
• Working directory: Repository root
• Python 3

Spec Registry

Spec	Description	Auth Required
main	Core Gemini API (generation, embeddings, files, models, etc.)	Yes
interactions	Experimental Interactions API (server-side state, agents)	No

Workflow

1. Fetch Latest Specs

# Fetch all specs + auto-discover new ones
python3 .claude/shared/openapi-toolkit/scripts/fetch_spec.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config

# Fetch specific spec only
python3 .claude/shared/openapi-toolkit/scripts/fetch_spec.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config --spec main

Output: /tmp/openapi-toolkit-googleai-dart/latest-main.json, /tmp/openapi-toolkit-googleai-dart/latest-interactions.json

2. Analyze Changes

python3 .claude/shared/openapi-toolkit/scripts/analyze_changes.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config \
  packages/googleai_dart/specs/openapi.json /tmp/openapi-toolkit-googleai-dart/latest-main.json \
  --format all \
  --changelog-out /tmp/openapi-toolkit-googleai-dart/changelog-main.md \
  --plan-out /tmp/openapi-toolkit-googleai-dart/plan-main.md

Generates:

• changelog-main.md - Human-readable change summary
• plan-main.md - Prioritized implementation plan (P0-P4)

3. Implement Changes

Before implementing, read references/implementation-patterns.md for:

• Model class structure and conventions
• Enum naming patterns
• JSON serialization patterns
• Test patterns and PR templates

Use templates from ../../shared/openapi-toolkit/assets/:

• model_template.dart - Model class structure
• enum_template.dart - Enum type structure
• test_template.dart - Unit test structure
• example_template.dart - Example file structure

3.5 Update Documentation (MANDATORY)

Before running the review checklist, update all documentation:

1. README.md - Add/update:

   • New resources to Features section
   • New resources to API Coverage section
   • New example references in Examples section

2. example/ - Create/update:

   • {feature}_example.dart for each new resource

3. CHANGELOG.md - Add entry for new features/changes

4. Review & Validate (MANDATORY)

Perform the four-pass review documented in references/REVIEW_CHECKLIST.md:

# Pass 2: Barrel file verification
python3 .claude/shared/openapi-toolkit/scripts/verify_exports.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config

# Pass 3: Documentation completeness
python3 .claude/shared/openapi-toolkit/scripts/verify_readme.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config
python3 .claude/shared/openapi-toolkit/scripts/verify_examples.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config
python3 .claude/shared/openapi-toolkit/scripts/verify_readme_code.py \
  --config-dir .claude/skills/openapi-toolkit-googleai-dart/config

# Pass 4: Property-level verification
python3 .claude/shared/openapi-toolkit/scripts/verify_model_properties.py \
  --config-dir .claude/skills/openapi-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/

Pass 4 is critical - catches missing properties in parent models (e.g., Tool, Candidate).

5. Finalize

# Copy fetched specs to persisted locations
cp /tmp/openapi-toolkit-googleai-dart/latest-main.json packages/googleai_dart/specs/openapi.json
cp /tmp/openapi-toolkit-googleai-dart/latest-interactions.json packages/googleai_dart/specs/openapi-interactions.json

# Run quality checks (from packages/googleai_dart)
cd packages/googleai_dart && dart test && dart analyze && dart format --set-exit-if-changed .

Troubleshooting

• API key error: Export GEMINI_API_KEY or GOOGLE_AI_API_KEY
• Network errors: Check connectivity; retry after a few seconds
• No changes detected: Summary shows all zeros; no action needed
• New specs discovered: Add them to config/specs.json and re-run
