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

Annotations already establish readOnlyHint=true and destructiveHint=false, so no safety clarification is needed. The description adds useful behavioral context beyond those annotations: results are org-scoped, paginated, and filterable. It does not disclose pagination defaults or accepted filter values, but the annotation safety profile lowers the bar.

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 front-loaded sentence with no filler. It states the resource, scope, and key behavioral qualifiers efficiently. Every word adds information value.

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 simple read-only list operation with no required parameters, the description is sufficiently complete to allow safe invocation. The main gaps are pagination defaults, possible status values, and response content shape, but the optional parameters and read-only annotations reduce the risk of an agent making a harmful or confusing call.

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 parameter clarity. 'Paginated, filterable' gives a useful high-level grouping for the four optional parameters, indirectly implying limit/offset as pagination and status/client_id as filters. However, it does not name which parameters map to which behavior, describe status values, or explain defaults, so the parameter semantics remain partially inferred.

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 uses a specific verb and resource: 'List builder projects for the org.' It also signals that the operation is paginated and filterable, which helps distinguish it from single-project getters like get_project. It does not explicitly contrast with sibling tools, but the plural resource and collection framing are clear.

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 implies the usage context: listing multiple builder projects with optional filtering/pagination. However, it does not explicitly say when to prefer this tool over alternatives like get_project, create_project, update_project, or list_clients, and it gives no exclusions or fallback guidance.

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