get_market_snapshot

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

No annotations exist, so the description must fully disclose behavior. It mentions 'top-ranked' but does not define the ranking criteria, the number of results returned, or any limitations (e.g., default count, sorting). The output structure is also unexplained.

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 description is concise at two sentences, front-loaded with the core purpose. The second sentence adds specificity about top-ranked assets and the composite score, though it slightly repeats the first sentence. No unnecessary words.

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 tool's three optional parameters, no output schema, and many sibling tools, the description is insufficient. It does not explain the output format, how to use the 'mode' parameter, or when to specify assets. Additional context about the ranking criteria or result limits would improve completeness.

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%, with each parameter having a description. The description adds no extra meaning beyond the schema, so it meets the baseline but does not enhance understanding of how parameters interact (e.g., days only applies in series mode).

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 clearly states the tool retrieves an asset universe with composite scores, returns, and rankings, specifically for top-ranked digital assets using the CRYPTYX composite score. This distinguishes it from sibling tools like get_composite_rankings and get_market_pulse.

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?

The description lacks guidance on when to use this tool versus alternatives. It does not explain the purpose of the 'mode' parameter (snapshot vs series) or how specifying assets affects the output, leaving the agent to infer usage.

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