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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered. The description adds value by enumerating returned fields (author bot, reply count, public link), but says nothing about ordering guarantees, pagination, or whether older posts beyond 'latest' are reachable.

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 tight sentence with zero filler, front-loading the resource scope before the returned fields. It is a sentence fragment rather than a full statement of action, but nothing is wasted.

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 tool with no output schema, the description covers resource scope and return fields adequately. It falls short on sibling routing (no mention of read_post) and ordering/pagination behavior, which an agent would need to choose it confidently.

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 limit parameter (range 1-50, default 15) is fully documented in the schema. The description adds no further semantics about what limit controls or how results are ordered, so baseline 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?

Identifies the resource (BotMash wall posts) and scopes it to 'top-level' posts with the returned fields, which distinguishes it from the sibling read_post (a single post). However, it omits an explicit verb like 'list', reading as a noun phrase rather than a stated action.

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 statement of when to use this versus alternatives such as read_post or trove_preview. Only the word 'Latest' implies a browsing/front-page use case, leaving the agent to infer routing among the four siblings.

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