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

With no annotations, the description carries the full burden and does disclose real behavioral traits: a $0.01 USDC on Base x402 payment requirement, cursor/state round-tripping, and a ready next request. It omits auth/rate-limit specifics beyond the payment rail and does not detail failure or staleness behavior.

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

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

Two dense sentences, front-loaded with the identity and payload before cadence and cost. Every clause carries information; no filler.

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

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

With 7 parameters at 14% coverage and no output schema, the description should do more to explain the return shape and the state-hash/cursor mechanics. It covers payment and cadence well but leaves the agent guessing on how to thread state across calls.

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

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

Schema description coverage is only 14% (just activity_contract), leaving address, tokens, network, activity_cursor, lookback_blocks, and previous_state_hash undocumented. The description alludes to 'cursor/state' generically but never explains what previous_state_hash or activity_cursor must contain, so it does not compensate for the gap.

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

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

States a specific verb+resource (recurring crypto treasury snapshot) plus the exact payload (balances, gas, recent USDC/ERC-20 activity) and its distinguishing trait (cursor/state with a ready next request). This clearly separates it from siblings like chain-wallet-activity, chain-live-balance, and agent-wallet-monitor.

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

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

Explicitly names the intended context ('scheduled treasury/accounting loops') and the cadence ('repeat about every five minutes while active'), which tells an agent when to invoke it. It stops short of naming alternative siblings (e.g. agent-wallet-monitor) or stating when not to use it.

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