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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuine behavioral context beyond that: results are ordered newest first, each release carries its events and associated issues, and the response is cursor-paginated.

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?

One front-loaded sentence with the resource and ordering stated first, then content, then pagination. It is tight, though the clause 'the issues it brought, brought back and resolved' is dense enough to require a second read.

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 burden of describing returns, and it does outline that each release includes events and issues plus ordering. Combined with fully documented parameters and pagination, an agent has nearly everything needed, with only the shape of the issue/event sub-objects left unspecified.

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 all four parameters (apps, appId, limit, cursor) are already documented with defaults and precedence rules. The description only echoes the cursor paging behavior ('Pages with cursor') and adds no new parameter meaning, making the baseline 3 correct.

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 states a specific verb+resource (releases of the key's apps) plus the ordering (newest first) and the nested content (events and the issues they brought, brought back, resolved). It is distinguishable from the sibling get_release by its list/multi-item scope, though it never names a sibling explicitly.

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 when-to-use or when-not-to-use guidance, and no reference to alternatives such as get_release for a single release. The scope hint (apps, pagination) implies broad listing but leaves the routing decision to the agent.

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