A3.9/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, non-destructive, open-world behavior, so the safety profile is covered. The description adds pricing ($0.01 per call), the default time window, and the shape of the returned structure cards (raised, taxes, concentration, ring block with verdict and basis), which is genuine added context.

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-loads price then purpose then usage, and each sentence carries information. It is telegraphic to the point of being choppy ('Not Solana. Fields: ...'), but there is little waste.

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

Completeness4/5

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

With an output schema present, return values need not be explained, yet the description still sketches the card contents, adds pricing and the default window, and rules out the Solana variant. Adequate for an agent to call it correctly, though a pointer to the RHC siblings would complete the picture.

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 all seven parameters are already documented in the schema. The description names only 'ring_only' and 'since' by way of filter mention and adds no syntax or format detail beyond the schema, which is the expected baseline when the schema does the work.

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

Purpose4/5

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

States a specific verb and resource ('new token launches on Robinhood Chain') and explicitly disambiguates from the Solana sibling with 'Not Solana'. The 'pons memecoins' jargon and 'structure cards' framing are a bit insider-y but the core action is clear.

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?

'Use to screen or poll new pons memecoins (default last hour)' gives the intended context and notes the default window. It stops short of naming the sibling alternatives (recent_launches, launches_since) the way an explicit when-to-use rule would, so it's clear context rather than full routing guidance.

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