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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so safety behavior is covered. The description adds nothing beyond the annotations—no return behavior, pagination, or scoping details—so it barely helps the agent understand how the tool behaves.

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?

The description is short but wasteful: the same endpoint path is repeated twice, and neither sentence is front-loaded with useful purpose or usage information. The operation ID sentence is the only non-redundant clause.

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?

This is a parameterized GET endpoint with nested query support and many near-identical sibling journal-entry endpoints. The description provides no differentiation, no parameter details, and no usage context, making it inadequate for correct selection and invocation despite annotations covering safety.

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 0%, and the description says nothing about the required `id` path parameter or the optional `query` object. It merely defers to describe_operation for native schemas, which does not compensate for the missing parameter semantics.

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 restates the endpoint path twice and adds no information beyond the name/title. It conveys that this retrieves journal entries for a lease, but that is already evident from the tool name and title. It does not distinguish this tool from the many sibling journal-entries endpoints.

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 guidance on when to use this tool versus alternatives such as the several other get_accounting_leases_by_id_journal_ent_* siblings or get_journal_entries_* tools. The only practical pointer is that describe_operation provides request schemas, which is not usage guidance.

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