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

With no annotations, the description carries the full burden, and it discloses the non-obvious prerequisite that AIPPT_APP_ID and AIPPT_API_SECRET environment variables must be set, plus the downstream dependency on template_id. It stops short of describing the returned list's shape or pagination behavior, so it is not fully self-contained.

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?

Purpose is front-loaded in one phrase, followed by a compact numbered list of usage notes. It is efficient and easy to scan, though the filter mention slightly duplicates the schema.

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 six-parameter list tool with no output schema, the description covers the essentials: the key output (template_id), prerequisites (env vars), and filtering. Only a sketch of the returned record structure is missing, which is a minor gap.

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%, so page_num, page_size, pay_type, style, color, and industry are all already documented in the schema. The description only restates the filter parameters (style/color/industry) without adding format, syntax, or value details, so the baseline 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 and resource ("获取PPT模板列表" / get the PPT template list) that no sibling duplicates — the other tools create tasks, outlines, or workflows, none list templates. An agent can immediately tell what this tool returns without opening the schema.

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?

Gives strong ordering context: the tool must be called first because the returned template_id is required for later PPT generation, and notes style/color/industry filtering. It lacks explicit when-not conditions or named alternative tools, but no sibling overlaps this function, so the guidance is essentially complete.

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