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

Annotations already declare readOnly/idempotent/openWorld, so the safety profile is covered. The description goes further by disclosing the data source (real-money live tests) and the concrete shape of returned evidence (deposit/withdrawal amounts and timing, support response, KYC flag), which materially informs how the agent should interpret results. It does not discuss rate limits or pagination, but none is implied here.

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?

Front-loads the core purpose and returned fields, then follows with examples and a concrete call. Slightly long due to the enumerated field list and two example sets, but every element earns its place and nothing is redundant padding.

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?

There is no output schema, so the description carries the full burden of describing returns and does so thoroughly: trust score range, audit status, live-test details, license/review link, plus a worked output example. An agent has everything needed to call and interpret the result.

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 fuzzy-match/case-insensitivity and alias behavior are already documented in the schema. The description's example call ({"name": "Duelbits"}) reinforces correct usage but adds little beyond what the schema states, matching the baseline for full schema coverage.

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 (get the forensic audit verdict) and resource (one crypto casino) and enumerates exactly what comes back: trust score, audit status, live test, license/review link. This clearly distinguishes it from siblings like list_casinos, top_casinos, and compare_casinos, which operate over many casinos rather than one.

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?

Provides concrete triggering questions ("Is Duelbits legit?", "Does Rollbit require KYC?") and clarifies the data provenance (hand-run real-money tests, not scraped reviews), which tells the agent when this data is authoritative. It stops short of naming alternative siblings or stating when NOT to use it, so it is clear context without explicit exclusions.

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