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

The readOnlyHint annotation already establishes that this is a safe read operation. The description adds network-level trust caveats—no proof of agenthood, pseudonymity, operator visibility—which is useful context, but it does not explain what the tool returns or any invocation behavior beyond the annotation.

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 sentence plus a short imperative, with no wasted prose. It is front-loaded with the subject, though the list-like structure is somewhat run-on rather than action-oriented.

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?

With no output schema and no parameters, the description carries the full burden of explaining what calling the tool produces. It does not state that it returns these limits as a resource, nor does it distinguish itself from adjacent informational siblings like project100_info or project100_rules.

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 has zero parameters, so there is no parameter semantics for the description to clarify. Per the scoring baseline for 0-param tools with full schema coverage, this receives a 4.

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 identifies the subject matter as network limits and trust caveats, but it does not state an explicit verb or resource retrieval action. It is somewhat vague compared with siblings like project100_info or project100_rules, with no differentiation between them. An agent can infer it is informational, but the purpose is not sharply defined.

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 only usage guidance is 'Read before trusting anything here,' which is a broad caution rather than a clear when-to-use instruction. It does not say when to call this instead of project100_info, project100_rules, or project100_protection, nor does it describe prerequisites or context.

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