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

Annotations declare readOnlyHint=true and openWorldHint=false, so the safety profile is already covered. The description adds value beyond that by disclosing sort order (most recently changed first) and the exact fields returned (id, title, link, edit permission), which is genuinely useful since no output schema exists.

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 sentence, front-loaded with the resource and scope, then the ordering and return fields. Efficient, though the trailing list of return fields makes it slightly run-on rather than maximally tight.

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 zero-param, read-only listing tool with no output schema, the description covers the essentials: what is returned, in what order, and with what fields. It omits pagination or result-limit behavior, which is the only notable gap.

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 tool takes zero parameters, so the schema has nothing for the description to compensate for. Per the baseline for parameterless tools, a 4 is appropriate; the description correctly avoids inventing parameter semantics that do not exist.

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 names a specific resource (Flett boards) and crisply defines its scope: boards the person owns plus boards shared with them. It is clearly distinguishable from the single-board sibling read_board and the write-oriented create_board, though it never uses an explicit listing verb, relying on the noun phrase to imply retrieval.

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 when-to-use guidance, no mention of alternatives such as read_board for a single board, and no stated preconditions. The scope wording implies the use case but nothing explicitly routes the agent.

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