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

Annotations already declare readOnly, idempotent, non-destructive, and open-world, so the safety profile is covered. The description adds genuine behavioral context beyond that: the response mixes measured on-chain values with values computed from volume, and it distinguishes already-collected fees from amounts still pending claim (pool creator fees, locked-LP harvest, creator curve vault) — a meaningful data-provenance disclosure.

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?

A single front-loaded sentence that leads with the scope ('one coin's fees') before the enumeration. It is dense but every clause maps to a distinct piece of returned data; the nested parentheticals make it slightly harder to scan than a bulleted breakdown would be.

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 no output schema, the description carries the burden of describing return values and does so thoroughly — fee lines, recipients, measurement method, volume, and unclaimed balances. The only real gap is the absence of any guidance on how this relates to the platform-level fee sibling.

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 coverage is 100% and the single mint parameter is fully documented in the schema, including the base58 pattern and the 'high' suffix convention. The description adds no syntax or format detail beyond the schema, so the 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?

The description names a specific resource (one higher.fun coin's fees) and enumerates exactly what is included: curve and Raydium pool fee lines, recipient attribution, on-chain vs computed origin, volume, and unclaimed amounts. It is clearly distinct from a platform-wide fee tool, though it never names the sibling (get_ecosystem_fees) that an agent might confuse it with.

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?

Usage is only implied by the scoping phrase 'One higher.fun coin's fees' — the agent must infer this is the per-coin drill-down versus the ecosystem-level view. There is no explicit when-to-use, when-not-to-use, or named alternative, and no mention that a mint address is required input.

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