Agent Skills: Categorise vault strategy

Categorise vault strategy

Assign evidence-based strategy tags to a known vault. Keep the maintained address-to-tag mapping next to its vault protocol adapter.

Workflow

1. Identify the vault and its adapter.

   • Resolve the chain and lowercase contract address from the supplied link, address, or name. Do not classify a same-address deployment on a different chain without confirming it is the same product.
   • For an ERC-4626 adapter, locate eth_defi/erc_4626/vault_protocol/{slug}/vault.py and read its description, short_description, nearby address overlays, and protocol metadata. Use the vault's official documentation or announcement to corroborate material claims.
   • Treat ApeX, Hyperliquid, GRVT, Hibachi, and Lighter as native perpetual DEX integrations, not VaultBase adapters. Their vaults are materialised by eth_defi/{slug}/vault_data_export.py with either an address, a platform vault ID, or a synthetic address.

2. Select tags from eth_defi.vault.strategy_tag.StrategyTag.

   • Assign every supported tag that the documented strategy warrants; tags are additive and are not mutually exclusive.
   • Prefer the most specific tag and include a relevant parent tag where it conveys useful search or reporting context. For example, an RWA lending vault normally receives both rwa and rwa_lending.
   • Do not infer a tag merely from a token symbol, protocol name, or generic yield marketing. When the strategy is not documented well enough, leave the address out of the mapping: get_strategy_tags() then returns None, meaning the information is missing. Use unknown only when a researched classification explicitly establishes that the strategy is unknown.

3. Create or update the protocol tag mapping.

   For a VaultBase adapter, use eth_defi/erc_4626/vault_protocol/{slug}/tags.py with plain lowercase string keys. Do not wrap table literals in verbose HexAddress(...) constructors:

   """Maintained strategy classifications for {Protocol} vaults."""
   
   from eth_defi.vault.strategy_tag import StrategyTag
   
   STRATEGY_TAGS: dict[str, set[StrategyTag]] = {
       #: Vault: Example RWA lending vault.
       #: Added: 2026-08-17.
       #: Decision material: The issuer describes this product as lending
       #: against real-world assets.
       #: Sources:
       #: - https://issuer.example/vaults/example
       "0x...": {StrategyTag.rwa, StrategyTag.rwa_lending},
   }
   

   Keep every EVM address key lowercase and scope every entry to an individual vault. lookup_strategy_tags() normalises the adapter's HexAddress input before looking up the string key. Put a Sphinx line-comment block immediately above every address-specific entry. It must include the vault name, the UTC date the tagging entry was added, and the decision material used to assign the tags. Include every page URL consulted during the decision directly in the comment; cite repository files by their path. Do not add an entry where the source material does not support the selected tags. Do not use a bundled or historical research snapshot as the sole evidence for a current address classification; verify the current metadata row or a current official protocol source before adding the entry.

   Aave, Euler, and Morpho adapters automatically add the generic StrategyTag.lending tag to every vault. Their STRATEGY_TAGS mappings are additive and should contain only additional address-specific classifications.

   For a native perpetual DEX, use eth_defi/{slug}/tags.py with string keys, because ApeX, GRVT vault IDs and Hibachi/Lighter synthetic addresses are not EVM addresses. Its resolver normally combines the maintained address-specific tags with StrategyTag.perpetual_futures. If the source description explicitly identifies a product as a non-perpetual RWA or fund product, omit that default for the address by adding its lowercase identifier to the protocol's NON_PERPETUAL_VAULTS set and documenting the exception in the entry comments; do not infer perpetual-futures exposure from the platform name alone.

4. Wire the classification into the correct data path.

   For a VaultBase adapter, ensure the corresponding vault class reads the mapping:

   from eth_defi.erc_4626.vault_protocol.{slug}.tags import STRATEGY_TAGS
   from eth_defi.vault.strategy_tag import StrategyTag, lookup_strategy_tags
   
   def get_strategy_tags(self) -> set[StrategyTag] | None:
       """Return maintained strategy tags for this vault."""
       return lookup_strategy_tags(STRATEGY_TAGS, self.vault_address)
   

   Return a copy so callers cannot mutate the maintained mapping. Preserve None for an address with no mapping entry.

   For a native perpetual DEX, import the resolver in its vault_data_export.py module and save its return value in the synthetic VaultRow as _strategy_tags. Do not add a fictional vault class or use HexAddress for a non-EVM identifier.

5. Add or update focused no-RPC coverage. For a VaultBase adapter, check the known address returns the exact tag set and an unmapped address returns None. For a native perpetual DEX, check both the default perpetual_futures tag and an address-specific tag added by its mapping. Format modified Python files and run the focused test.

6. Schedule the production database migration.

   • Do not update ~/.tradingstrategy/vaults/vault-metadata-db.pickle on a local development machine as part of this workflow. The pickle is a materialised cache; the resolver and focused tests are the source-controlled change.

   • After opening the pull request, post the production migration instructions below as a pull-request comment. The operator must run them only after the code is merged and deployed.

   • Stop the persistent scanner before the migration so it cannot overwrite the metadata pickle. Run the dry run, inspect its output, then apply the migration and restart the scanner:

     source ~/vault-scanner/vault-rpc.env && (cd ~/vault-scanner/web3-ethereum-defi && docker compose stop vault-scanner-looped)
     source ~/vault-scanner/vault-rpc.env && (cd ~/vault-scanner/web3-ethereum-defi && docker compose run --rm --entrypoint /bin/bash vault-scanner-oneshot -lc 'DRY_RUN=true python scripts/erc-4626/migrate-vault-strategy-tags.py')
     source ~/vault-scanner/vault-rpc.env && (cd ~/vault-scanner/web3-ethereum-defi && docker compose run --rm --entrypoint /bin/bash vault-scanner-oneshot -lc 'DRY_RUN=false python scripts/erc-4626/migrate-vault-strategy-tags.py')
     source ~/vault-scanner/vault-rpc.env && (cd ~/vault-scanner/web3-ethereum-defi && docker compose up -d vault-scanner-looped)
     

Chat output

When reporting a completed categorisation, output one entry per vault with:

• Vault name
• Vault address
• Tags added
• Link to the production migration comment when a pull request was opened.
