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

Annotations already declare the safe read-only profile, and the description adds genuinely useful behavior beyond them: data visibility differs by ownership (owner sees everyone's hours and monetary amounts; members see only their own hours and no money), budget thresholds are flagged (ok, warning from 80%, over), and the result also includes owner boards that could become projects plus any sample project. This is substantive disclosure an agent could not infer from annotations.

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?

The leading sentence front-loads the verb and resource well, but the middle sentence on ownership semantics is dense and slightly overstuffed, and the returned-field enumeration is heavy for one sentence. No sentence is pure waste, but the description runs longer than its core message needs.

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?

There is no output schema, so the description carries the return-value burden and does so by enumerating the fields returned and the ownership-dependent visibility rules. Combined with annotations covering safety, an agent has enough to call and interpret the result, though sibling differentiation is still absent.

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%, so q, sort, status, and clientId are fully documented in the schema, making 3 the baseline. The description repeats some status values but adds no syntax, default, or filtering semantics beyond what the schema already provides (e.g., the 'open = active and on hold' nuance lives only in the schema).

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?

States a specific verb (Lists) and resource (projects), and clarifies the resource as 'boards with project settings', which disambiguates from raw boards. It enumerates the returned fields (client, status, dates, hours, budget), giving a precise picture of the payload. However, it never names or contrasts with the closest siblings such as list_boards or get_project_summary.

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 explicit when-to-use guidance or any named alternative. The description explains visibility semantics (owned vs member projects) but that is behavioral context, not a selection rule. An agent gets no help deciding between this and list_boards, get_project_summary, or search.

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