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

The description adds useful behavioral context beyond the readOnly/idempotent/openWorld annotations: it calls only the GET /v4/markets/{marketAddress} endpoint, returns that response directly, and covers multiple DEX sources. It does not mention auth or rate limits, but the annotations already establish the safety profile.

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 endpoint and scope are front-loaded, but the first sentence repeats the title 'Market Details' with little added value, and the second sentence redundantly says 'Solana API endpoint ... on Solana.' The content is short but not maximally efficient.

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?

Given the rich annotations, 100% schema coverage, single required parameter, and existing output schema, the description gives enough context to invoke the tool correctly. It could be more complete by explicitly contrasting this tool with list-markets or get-market-candles.

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%, so the baseline is 3. The description adds meaning by clarifying that the address may identify either a market or a pool across Pump.fun, Raydium, and other supported venues, which goes beyond the schema's generic 'Solana public key identifier' wording.

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 states a specific resource (a specific market on Solana) and ties it to the exact endpoint GET /v4/markets/{marketAddress}. It distinguishes 'specific market' from a listing operation, but does not explicitly name the sibling list-markets tool.

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 implied by 'fetching details about a specific market on Solana' and by mentioning market/pool address filtering across Pump.fun and Raydium. However, there is no explicit guidance on when to use this instead of list-markets or get-market-candles.

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