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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful context (non-custodial launchpad, returned data fields, 'free discovery feed'), but it does not disclose other behavioral details such as rate limits, pagination, auth requirements, or error 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?

The description is two short sentences with no filler. It front-loads the core action and resource, packs the relevant output data into a compact list, and the 'free discovery feed' phrase reinforces usage context without bloating the text.

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 read-only list tool with zero required parameters and fully documented optional parameters, the description plus schema and annotations are adequate for correct invocation. The description provides the key output themes, though it does not detail response structure or pagination; this is a minor gap for a list endpoint.

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 all four parameters already have meaningful descriptions (sort, limit, status, chain_id). The tool description adds no extra parameter-level semantics, so the baseline of 3 is appropriate.

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?

The description uses a specific verb and resource: 'List tokens on the non-custodial EventTrader launchpad (Robinhood Chain)' and enumerates the content ('live curve prices, graduation progress, volume'). This cleanly distinguishes it from siblings like launchpad_get_token (single token), launchpad_list_launchers (launchers), and launchpad_launch_token (mutation).

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?

The description implies a discovery use case with 'Free discovery feed', and names the resource being listed, but it does not explicitly say when to use this tool versus alternatives, nor does it provide exclusions or point to a sibling like launchpad_get_token for single-token lookups.

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