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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered structurally. The description adds no behavioral context beyond that — no mention of scoping to a project/site, whether results are paginated, or whether templates are user-created versus system-provided.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though the brevity reflects under-specification rather than disciplined economy.

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 two undocumented required parameters and no output schema, the description should carry the burden of explaining scope and result shape, but it does not. For a listing call whose only inputs are unfiltered IDs, this leaves the agent guessing about how to call it correctly.

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?

Both parameters (projectId, siteId) are required with 0% schema description coverage, and the description never mentions them or explains that the listing is scoped by project and site. The description therefore does not compensate for the schema gap; an agent must infer that these two IDs determine what is returned.

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 specific verb ("List") and resource ("email templates available for outreach"), which is unambiguous against siblings like create_outreach_template, delete_outreach_template, and update_outreach_template. It does not explicitly name those siblings, so differentiation comes from the verb alone rather than deliberate contrast.

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 call this versus alternatives such as get_outreach_draft_options or list_outreach_threads, nor prerequisites. Nothing indicates that a project/site scope is required to get meaningful results, which is central to using this tool correctly.

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