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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds real value by naming the data provenance (DEX Screener) and the address format requirement, which annotations cannot express. However it says nothing about what the response contains (liquidity figures, pair/pool breakdown, empty-result behavior for unknown mints) or about failure on malformed addresses.

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 clause-packed sentence with the action and data source front-loaded and the input constraint trailing as a prerequisite. No filler, no repetition of the tool name or annotations.

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 single-parameter read-only lookup with no output schema, the definition covers what the tool reads and what input it needs, but leaves the return payload entirely unspecified, which matters because 'liquidity' could mean many metrics. OpenWorld annotation signals external-dependency variability but the description doesn't address it (e.g., mint not indexed by DEX Screener).

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 0% and the schema only constrains length (32-44 chars), so the description carries the full burden of explaining the parameter. It does so by specifying 'valid Solana base58 address' and tying it to a Solana mint, which is the key semantic an agent needs. It does not clarify formatting edge cases (case sensitivity, whether the address must be the mint rather than a pool or owner), keeping it out of 5 territory.

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 ('Inspect'), a specific data source ('DEX Screener reported'), and a specific resource ('Solana mint liquidity'), which is enough to distinguish it from the research/perps siblings. It stops short of naming any sibling or contrast case, so a 5 isn't warranted.

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: an agent can infer 'call this when you need liquidity data for a Solana mint.' The one explicit constraint is the prerequisite of a valid base58 address. There is no statement of when not to use it or what to use instead for non-Solana or non-mint assets.

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