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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered. The description adds only the endpoint path, with nothing about ordering, page-size defaults, or what a template object contains — the gaps are real but the bar is lower given annotation coverage.

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?

Two short fragments, front-loaded with the purpose, with zero filler. The trailing endpoint string is nearly redundant with the description, slightly costing it a point on tightness.

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 simple filtered-list tool with full schema coverage and safety annotations, the description is minimally sufficient. However, there is no output schema, so the description would ideally sketch the shape of a returned template; it does not.

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 100%: name, limit and offset are all documented in-schema, including the useful "Pass the previous reply's next_offset" hint. The description contributes nothing beyond that, so the baseline of 3 applies.

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+resource ("List reusable message templates") and reinforces it with the underlying endpoint path. An agent can distinguish this from sakari_get_template and sakari_create_template on the name alone, so the description doesn't need to spell out the 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?

No statement of when to reach for this versus sakari_get_template (single lookup) or sakari_list_autoresponders/other list tools. Usage is only implied by the verb "List"; there are no exclusions or prerequisites given.

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