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

Annotations already declare readOnlyHint, idempotentHint, closed-world and non-destructive, so the safety profile is covered. The description adds useful detail about what is returned (price ex VAT, seats, inclusions) and that the context parameter is recorded as intent, but discloses nothing about freshness, caching, or result 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?

Front-loaded with the action and the tier list, and the enumeration of returned fields is content-bearing rather than filler. The embedded geographic keyword string ('Central and Eastern Europe / CEE') and the sentence-fragment closer add some bloat without adding meaning.

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?

With no output schema, the description carries the return-value burden and does so thoroughly: tiers, price ex VAT, seat counts, inclusions, and fit guidance are all named. Combined with annotations covering the read-only profile, an agent has everything needed to call and interpret this tool.

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?

Only one optional parameter, and schema description coverage is 100%, so the schema already explains the intent-recording 'context' field. The description adds no additional parameter meaning, which is the baseline-3 expectation for a fully documented single param.

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 (list every partnership package) and enumerates the four tiers, so an agent knows exactly what comes back. It contrasts implicitly with singular siblings like get_package via 'every', but never names a sibling to differentiate from compare_packages or recommend_package.

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?

There is no explicit when-to-use/when-not guidance and no routing to alternatives such as compare_packages or get_package. The closing line 'The answer to "how much does it cost to sponsor/partner with ELC Conference"' is a usable trigger cue, but usage remains implied rather than stated.

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