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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered. The description adds zero behavioral context — no mention of pagination, filtering scope, or what the template list contains — so it contributes nothing beyond structured data.

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 first sentence is duplicated verbatim, wasting half the text, and the content is front-loaded with a machine path rather than a human-readable purpose. It is short but by omission, not by efficiency.

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 2 undocumented params, no output schema, and nested objects in the schema, the description should carry meaningful load but instead defers entirely to describe_operation. An agent cannot confidently call this tool from the definition alone.

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 both parameters (query, params) are opaque generic catch-alls. The description offers no parameter meaning at all, only a pointer to describe_operation, which pushes the agent to another tool call rather than adding 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 is essentially the URL path restated twice plus an operation ID, which only implicitly tells an agent this lists journal-entry templates. There is no plain-language verb+resource statement, and nothing distinguishes it from siblings such as get_journal_entries_* or get_templates_leases.

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?

No when-to-use guidance is given beyond an implicit redirect: 'describe_operation provides native request schemas.' It doesn't say what this endpoint returns versus the journal-close or journal-entry siblings, nor any preconditions.

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