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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description only adds that each application's type and settings are returned; it says nothing about result size, pagination, or what happens when the connection has no applications. With annotations carrying the main burden, a 3 is appropriate.

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 short sentences, front-loaded with what is listed and followed by the usage hint. No filler, though the second sentence could have been used to add sibling routing rather than a soft usage note.

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 simple, read-only, single-optional-parameter list tool with full annotation coverage and complete schema descriptions, the description covers what it returns and why an agent would call it. Only minor gaps remain (empty-connection behavior, result scope).

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 'connection' parameter already documents that it can be an id or label from list_connections and defaults to the user's default connection. The description adds no parameter-level information, so the baseline 3 applies.

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 ('Lists the applications in the connected Oracle EPM environment') and names what is returned ('type and settings'). It does not contrast itself with siblings like list_connections, so it falls short of a 5.

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?

'Use it to find the application name other tools need' gives a concrete usage context, which is more than nothing. However, there are no exclusions, no prerequisites, and no explicit pointer to the alternative tools that consume the returned name (e.g. run_business_rule, export_data_slice).

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