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

All annotations are false, so the description carries the full burden, and it delivers substantial behavioral context: templates have no connection attached, entries are validated as a set so one bad name rejects the whole call, frozen_params pins values callers cannot override, and sharing exposes only names and pinned parameters, never a connection. It also states the return value including the new tpl_… id, which is critical since there is no output schema.

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 dense paragraph, but every sentence adds value and the key fact is front-loaded. It could be trimmed slightly without losing information, but the length is justified by the number of non-obvious behaviors and cross-tool references the agent needs.

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?

Given the tool's complexity, the complete schema, and the absence of an output schema, the description covers everything needed: the template concept, the no-connection rule, entry validation behavior, sharing semantics, related alternative tools, and the return value. No essential operational detail appears to be missing.

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?

With 100% schema description coverage the baseline is 3, but the description adds meaning beyond the schema: it explains that entries can be omitted and filled later, that proxy entries require connector_slug + tool_name (never connection_id), that tool names should come from connection.list_tools, and that shares grants access at creation time. These clarifications materially improve correct parameter selection.

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 opens with 'Create a template' and immediately defines precisely what a template is: a named, shareable group of tool references with no connection attached. It also contrasts this with toolbox.create, clarifying the resource and scope unambiguously and distinguishing the tool from siblings like template.update, template.share, and toolbox.create.

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 gives explicit when-to-use guidance: it says entries is optional and can be filled later with template.set_entries, advises sourcing tool names from connection.list_tools, points to template.share for the sharing-level ladder, and explicitly contrasts with toolbox.create ('unlike toolbox.create there is nothing to warn about'). An agent can route correctly without guessing.

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