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

With no annotations, the description must carry the full behavioral burden. It does disclose that the operation is read-only, which is the single most important safety fact, but says nothing about result ordering, pagination via limit, or what 'graduated/completed' means operationally.

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 tight sentences, zero filler. The scope constraint and the default behavior are front-loaded before the optional narrowing parameter, which is the right order for an agent scanning for a routing decision.

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?

For a four-parameter, no-annotation, no-output-schema tool, the description covers the two semantically richest parameters but omits limit/pagination behavior and liquidity filtering. An agent can invoke it, but the boundary against the screening and trending siblings remains unstated.

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 25%, so the description should compensate more than it does. It usefully decodes the stage values ('newly created, near-completion, graduated') and the launchpads scoping, but leaves limit and minLiquidityUsd entirely unaddressed.

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 ('discovery') and resource ('Robinhood Chain launchpad tokens'), and enumerates the three lifecycle stages it covers, which maps directly onto the stage enum. It is distinguishable from generic siblings like trending or signals, but it never names a sibling tool to contrast against, so it stops short of a 5.

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?

It gives the default scope ('chain-wide by default') and the narrowing condition ('pass launchpads to restrict to Pons or Trench'), which is useful routing information. However, it never says when to prefer this over screen_robinhood_launchpads or trending, so the alternative-selection guidance is only implied.

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