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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds no useful behavioral context and instead offers an unrelated note about MCP approval requirements being administrator-configurable, which does not apply to a read-only list operation and may mislead the agent into thinking approvals gate this call.

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 definition is short and the purpose sentence is front-loaded, which is good. The second sentence is boilerplate that does not earn its place because it does not relate to listing templates.

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?

An output schema exists, so return values need not be explained here, and annotations cover safety. However, for a listing tool with pagination and search parameters, the absence of any guidance on filtering, result limits, or when to prefer a sibling list tool leaves the agent under-equipped.

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% and the description never mentions limit, offset, or search, so pagination and search behavior are entirely undocumented. With three parameters and no schema descriptions, the description was required to compensate and does not.

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 states a specific verb and resource ('Find project budget templates'), which is enough to distinguish it from the many create/get/update/delete siblings on the same resource. It does not, however, differentiate it from adjacent list tools such as list_budget_templates or list_project_budget_template_items, which an agent could easily confuse it with.

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 statement of when to call this versus list_budget_templates, get_project_budget_template, or create_project_budget_template. The only second sentence concerns approval configuration, which gives no guidance about selecting this listing tool.

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