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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that this is a GET endpoint and specifies 'manual' journal entries, but does not add notable behavioral details such as default status exclusions or pagination expectations beyond what the schema already documents.

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 two short elements with no wasted text: a front-loaded statement of what the tool lists and the endpoint. It is appropriately sized for a straightforward list operation.

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 read-only list tool with complete schema descriptions and clear annotations, the description is largely sufficient. It identifies the resource and filters, though it could have explicitly contrasted this with bukku_get_journal_entry or noted that void entries are excluded by default.

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 seven parameters are already well documented. The description mentions date, status, and keyword filtering, which aligns with the schema but adds no extra syntax, default, or interaction detail beyond what the schema provides.

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 gives a specific verb and resource: 'List manual journal entries.' It also names the supported filter axes (date, status, keywords), which makes the tool easy to distinguish from the single-entry sibling bukku_get_journal_entry, though no explicit sibling differentiation is stated.

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 implies this is the listing/search endpoint for journal entries, which is useful context. However, it does not explicitly say when to use this instead of bukku_get_journal_entry or mention any exclusions, so the routing guidance remains implied rather than explicit.

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