You are helping me build the following AI agent workflow.

## Goal
Sync MySQL Schemas to Pinecone: Syncs MySQL table schemas to Pinecone as vectors, detecting changes via hashes to update only modified definitions for AI retrieval.

## Specification
- What it does: You get instant AI retrieval for your database structure by syncing MySQL table schemas to Pinecone as searchable vectors. The system automatically detects changes via hashes and only re-indexes modified definitions, ensuring you always have up-to-date data without duplicating existing information.
- Trigger: Run manually (Manual · on demand)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - MySQL: Discover and read database table schemas
  - Embeddings OpenAI: Generate vector embeddings for schema text
  - Pinecone Vector Store: Store and retrieve schema vectors
  - Code: Calculate hashes and manage logic flow

## Known pitfalls, handle each one explicitly in your implementation
1. Schema changes in MySQL can be subtle so always compare the new hash against the previous one before triggering an expensive re-embedding process.
2. Metadata fields must match Pinecone's metadata schema exactly or the upsert will fail silently so validate field types before sending requests.

## Reference implementation
https://n8n.io/workflows/11971 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
