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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=false, so the description must add what actually gets destroyed or replaced. It instead offers a vague note that 'MCP approval requirements are configurable' and 'business workflow approvals always apply' without explaining the approval mechanism, reversibility, or whether 'data' replaces or merges existing template fields. The word 'Edit' understates the destructive semantics but does not directly contradict the 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?

Very short and front-loaded with the action, which is good. But the second sentence is generic approval boilerplate with ambiguous scope ('MCP approval requirements') that does not clearly earn its place for this specific tool.

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 destructive, non-idempotent mutation taking a nested replacement object with zero schema coverage, the description omits nearly everything an agent needs: which fields are editable, merge vs replace behavior, and what authorization/approval actually gates the call. The output schema covers return values, so that omission is acceptable, but the input-side gap is large.

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 mentions no parameter at all. The nested 'data' object with additionalProperties=false likely means whole-object replacement, and the uuid 'id' format is undocumented — exactly the semantics the description needed to compensate for 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?

States a clear verb and resource: 'Edit a project_task template.' An agent can identify the object being modified. However, it does not distinguish this from close siblings such as update_project_task_template_item, update_task_template, or apply_project_task_template.

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 guidance on when to use this versus the many adjacent template tools (apply vs update vs update_item). The second sentence concerns approval governance, not selection criteria, so it does not help an agent choose this tool.

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