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

Annotations already establish readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that: the permission nuance ('Only the project owner reads the rate and the money budget') and the domain constraint that a settings-less board is not yet a project.

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?

Three tightly packed sentences: the returned fields are front-loaded, followed by the domain constraint and the permission caveat. No redundant restatement of the name or title, and every sentence carries information an agent can act on.

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 read-only, single-parameter tool with no output schema, the description covers the essential ground by enumerating the returned fields and disclosing the owner-only visibility rule. The only meaningful gap is the absence of any description of boardId semantics.

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 0%, so the description must compensate for the one parameter, and it does not: boardId is never mentioned, described, or given format expectations. The phrase 'a board's project settings' faintly implies boardId identifies the board, but that is minimal and the coverage gap goes unfilled.

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 verb ('Reads') and resource ('a board's project settings') and then enumerates the exact fields returned (client, status, budget, hourly rate, billable flag, dates), which is highly specific. However, it never differentiates itself from closely named siblings like get_project_summary or get_board, leaving some ambiguity about which read tool to pick.

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?

Usage is implied rather than stated: the note 'A board without settings is not a project yet' hints at a precondition for meaningful results, and the owner-only clause implies a permission gate. But there is no explicit when-to-use guidance and no mention of alternatives such as get_project_summary or get_board.

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