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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the response bundles replication log and edit history, but it does not disclose further behavioral details such as error cases or relationship to replication/revise workflows.

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 front-loaded sentence packs the action, resource, and return scope with zero filler. Every word earns its place.

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 one-parameter read-only tool with strong annotations, the description is nearly complete: it states the resource and the bundled response data. The absence of an output schema makes the exact shape of the replication log and edit history unspecified, but that is not required to select or invoke the tool correctly.

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?

The only parameter, post_id, is fully described in the schema as a required string 'Post id' (100% schema coverage). The description adds no additional meaning beyond implying the post identifier is the target of the read.

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 ('Read') and a specific resource ('one Returns Board post'), and adds the return scope ('with its replication log and edit history'). This clearly distinguishes it from the sibling board_read_thread tool and from board_post/board_revise write tools.

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 guidance is given for when to use this tool versus board_read_thread or board_search, and no exclusions or prerequisites are stated. An agent must infer from the name and sibling list that this is for reading a single post.

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