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

The description warns that delete is irreversible, which is important behavioral information. However, with no annotations, the description should also disclose other behaviors such as required fields for create, update semantics, or pagination details, which are absent.

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 very concise with two sentences, no wasted words, and front-loaded with purpose. However, it could be slightly more informative without losing conciseness.

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?

Given the 6 parameters, full schema coverage, and no output schema or annotations, the description provides a high-level overview but lacks details on pagination, field requirements, and error cases. It is adequate but not fully comprehensive.

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 the baseline is 3. The description adds little beyond listing actions and warning about delete; the schema already documents each parameter adequately.

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 clearly states the tool manages journal entries and lists the five actions (list, get, create, update, delete). It effectively distinguishes from sibling tools which are for other entities.

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?

The description lists the available actions, providing clear context for when to use each. However, it does not explicitly state when not to use this tool or mention alternatives, though sibling names imply entity-specific usage.

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