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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered, but the description adds nothing beyond that. It does not say the template is bound to a project/site, whether duplicate names are permitted, or how placeholder tokens in subjectTemplate/bodyTemplate are interpreted.

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?

It is a single short sentence, but the brevity is under-specification rather than efficiency. There is no wasted wording, but the sentence carries no useful payload.

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 mutating, 6-parameter tool with a nested object, five required fields, zero schema descriptions, and no output schema, the description is wholly inadequate. An agent cannot determine required inputs, template placeholder semantics, or scoping from this text.

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% across 6 parameters, so the description carries the full explanatory burden and provides none of it. Nothing explains name constraints, subject/body template syntax, or the nested fallbackValues object — all of which an agent must understand to call this correctly.

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 says 'Create an email template,' which is essentially a restatement of the tool name and title 'Create an outreach template.' It identifies a verb and resource but adds no distinguishing detail (placeholders, subject/body structure, project/site scoping) and does nothing to separate it from siblings like create_outreach_draft or update_outreach_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 create a template versus drafting a one-off reach-out (create_outreach_draft) or modifying an existing template (update_outreach_template). Nothing indicates prerequisites, required project/site context, or reuse intent.

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