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

The readOnlyHint annotation already establishes this as a safe read operation. The description adds that the response includes journal entry lines, which is useful return-content context, but it does not address not-found behavior, error conditions, or deeper retrieval semantics.

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 short and front-loaded, with no wasted words. It is perhaps overly terse, and the parenthetical '(verification)' is slightly ambiguous, but it remains efficient.

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 one-parameter getter with annotations covering read-only safety, the description provides the minimum viable context by naming the returned entity and its lines. However, with no output schema, it does not describe the response shape or failure behavior, leaving some gaps.

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% for the lone journalEntryId parameter, and its GUID pattern is documented in the schema. The description adds no additional parameter meaning, so the baseline of 3 is appropriate.

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 identifies a single journal entry and notes that its lines are included, clearly distinguishing it from the plural list_journal_entries sibling. The verb is implied by the tool name/title rather than stated in the description itself, but the resource and scope are unambiguous.

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 siblings such as bokio_list_journal_entries, bokio_create_journal_entry, or bokio_reverse_journal_entry. It also omits any prerequisites or conditions for retrieval.

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