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

Annotations already cover readOnly, idempotent, openWorld, and non-destructive semantics. The description adds real context by disclosing that this is a thin passthrough of GET /v4/markets and what the response contains, but it says nothing about pagination behavior despite page/limit parameters, nor about rate limits or response size.

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?

Four short sentences, front-loaded with the core resource and the endpoint it wraps. Minor redundancy in restating the title and repeating 'Solana' multiple times, but nothing is wasted.

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?

An output schema exists, so the return values need not be explained in depth, and annotations are rich. However, with six optional parameters including four opaque public-key filters, the description should clarify that the mint addresses act as filters and how page/limit interact — that gap keeps this at minimum-viable.

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 the baseline is 3. The description reinforces the programAddress filter but adds nothing for page, limit, or the baseMintAddress/quoteMintAddress/tokenMintAddress parameters, whose schema text is generic ('Typed Solana public key identifier used across request parameters and response fields').

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 and resource ('fetching Solana DEX markets by program address') and enumerates the returned data (market IDs, token pairs, program names for Pump.fun, Raydium). It does not explicitly distinguish itself from the sibling get-market, but the 'list' vs 'get' framing plus the filter description makes the distinction inferable.

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: the agent can infer this is for enumerating markets filtered by program address. There is no explicit when-to-use, no mention of when to prefer get-market for a single market, and no guidance on list-supported-dexes as an alternative.

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