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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates the tool returns status and recent activity, but does not explicitly state that it is a read-only operation, nor does it disclose potential errors, permissions, or side effects. It lacks details on response format or limitations, leaving significant behavioral ambiguity.

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 description is a single, concise sentence that immediately conveys the tool's purpose and a key usage detail. There is no filler, redundancy, or unnecessary jargon. Every word earns its place, and the structure is front-loaded with the core action and object.

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?

The tool is simple (two optional parameters, no nested objects), but it lacks an output schema, and the description does not explain the structure of the returned status or recent activity. The description gives a high-level summary but leaves the agent guessing about the exact response fields. Given the simplicity, this is adequate but with clear room for more detail about output expectations.

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 descriptions of both parameters in the input schema already convey their optionality and mutual exclusivity. The tool description adds the phrase 'You can use either the project name or ID,' which reinforces the alternative relationship but does not add substantive new information. Schema coverage is 100%, so the baseline of 3 is appropriate; the description adds marginal value.

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 clearly states the tool's function: 'Get the current status of a project including recent activity.' It uses a specific verb ('Get') and identifies the resource (project status) and scope (including recent activity). However, it does not explicitly differentiate from sibling getter tools like get_team_details or get_live_activity, though the project-specific focus provides partial distinction.

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or scenarios favoring this tool. The only usage hint is 'You can use either the project name or ID,' which is parameter guidance rather than high-level usage context. No mention of when not to use it or alternative tools is present.

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