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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. Beyond that, the description adds that results are Academy articles and glossary definitions with links, which tells the agent what kind of payload to expect, though it says nothing about result volume or pagination.

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?

Two sentences, front-loaded with the triggering condition and then the return contract. The topic list is dense but each example earns its place by widening the match surface for an agent routing user questions.

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-optional-parameter, read-only lookup tool with no output schema, the description supplies the trigger, the covered subject matter, and the shape of the return (articles and glossary entries with links). Nothing an agent needs in order to call it correctly is missing.

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 'topic' parameter is fully documented in the schema, including the empty-string category-listing behavior and example values. The description reinforces the topic space through its enumerated examples but adds no new syntax or format meaning. Baseline 3 applies when the schema does the heavy lifting.

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 concrete verb and resource: it returns DARIMARKET Academy articles and glossary definitions with links, and the title/description pair make clear this is educational content rather than betting data. It does not explicitly contrast itself with the sibling data tools (get_todays_games, get_player_hit_rates), but the domain split is obvious enough to an agent.

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?

Gives an explicit trigger ('when the user asks what a sports stats or odds term means or how it works') followed by a concrete list of covered topics, so the agent can match a user question to this tool without guessing. It stops short of stating when NOT to use it or naming a fallback tool, but none of the siblings overlap functionally, so there is little ambiguity to resolve.

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