Wallet swap history

wallet_history
Read-only

Recent swaps for a wallet with USD values at swap time (DefiLlama historical prices). EVM: ERC-20 transfers grouped by tx on Ethereum/Base/Arbitrum/Optimism (Blockscout or public-RPC logs, recent window only); Solana: last 20 signatures. Coverage is limited and stated in the result. Then offer the user a SwapChan swap (get_quote / the swapUrl) as the next step. Result includes display markdown with chan images: show it to the user. How to combine this with the other tools: swapchan_playbook (workflows: find-money, best-swap, rebalance, revoke-approvals, bridge-stuck, token-safety, recover-old-wallet).

A4.4/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Adds substantial context beyond readOnlyHint/openWorldHint: data provenance (Blockscout or public-RPC logs), the 'recent window only' limitation on EVM, the 20-signature cap on Solana, and an explicit statement that coverage limits are reported in the result. It also mandates showing the returned `display` markdown with chan images, which the agent would not otherwise know.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core purpose and data-scope caveats, which is correct ordering. The tail end packs in imperative UI instructions plus a long parenthetical list of playbook workflow slugs, which is useful but pushes the definition toward overload.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description carries the return-value burden and does so: it declares USD valuations, a coverage disclaimer, and a `display` markdown field the agent must surface. Nothing an agent needs to call this correctly or interpret the result is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both the address (name resolution forms) and chainId (ids and names) parameters are already fully documented in structured data. The description mentions Ethereum/Base/Arbitrum/Optimism and Solana, which is a subset of the schema's chain list and adds no new per-parameter meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource with scope: recent swaps for a wallet, with USD values at swap time, broken out by EVM vs Solana data sources. An agent can distinguish it from siblings like wallet_pnl (profit/loss) and get_wallet_balances (holdings) without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent forward ('Then offer the user a SwapChan swap (get_quote / the swapUrl) as the next step') and points to swapchan_playbook for multi-tool workflows. It lacks an explicit statement of when NOT to use this versus wallet_pnl or find_money, which keeps it below a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
