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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds useful content disclosure — counts, graduation status, whether the dev sold, and how the latest launches ended — but says nothing about ordering, limits on 'latest', or error behavior for a wallet with no launches.

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?

Short and front-loaded with the scope statement first, then the returned facts. Minor redundancy: 'on Robinhood Chain' appears in back-to-back sentences, and the second sentence is a compressed list rather than clean prose.

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?

No output schema exists, so the description carries the return-value burden and does so by enumerating the aggregate and listing fields. It is nearly complete for a two-parameter read tool; only limits on the 'latest launches' list and empty-result behavior are unaddressed.

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 100%, so both parameters are already documented (wallet 0x-pattern, chain rh=4663 with default). The description only restates 'one wallet' and 'Robinhood Chain', adding no syntax, case-sensitivity, or defaulting insight beyond the schema, so baseline 3 applies.

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?

Opens with a specific verb-resource framing: every coin a given wallet deployed on Robinhood Chain, plus aggregate stats (count, bonding-curve graduations, dev-sold flag, latest launches and outcomes). The deployer-wallet scope distinguishes it reasonably from siblings like launch_record or check_coin, though it never names those siblings explicitly.

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?

There is no when-to-use or when-not-to-use guidance at all. The description never points to launch_record, check_coin, fresh_launches, or wallet_privacy as the alternative depending on whether the agent wants a single coin, a single wallet's general activity, or a dev's launch history.

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