Get journal entry comment

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, and the description's 'Fetches' is consistent. It adds only the one-result cardinality; no additional details about error behavior, auth, or response shape.

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?

A single seven-word sentence that is front-loaded and contains no filler. Every word adds value.

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 two-parameter read-only GET with annotations covering the safety profile, the description sufficiently identifies the resource and cardinality. It does not mention the response shape or that commentId must belong to journalEntryId, but those are largely inferable from sibling tools and parameter names.

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 coverage is 100%, but both parameter descriptions are tautological ('Path parameter commentId' / 'Path parameter journalEntryId'). The tool description adds no semantic meaning beyond the schema, so baseline 3 applies.

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 uses a specific verb and resource: 'Fetches one comment on a journal entry.' The singular 'one' clearly distinguishes it from siblings like bokio_list_journal_entry_comments and bokio_get_journal_entry.

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 singular phrasing implies this is for retrieving a specific comment, but it never explicitly says when to use it versus listing comments or when not to use it. No alternatives are named.

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