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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does describe the output content (pillars, hooks, CTAs, tags, reminders) which is the core behavior, but it does not disclose side effects, whether this is a pure generation operation, or any limitations. The existence of an output schema relieves it of explaining the return format. Adequate but not rich.

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 dense sentence, front-loaded with the main purpose (generate rolling calendar) followed by compact specifics. Every clause earns its place: pillar rotation, per-item hook/CTA/tag, and reminder inclusion. No filler or repetition.

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 generation tool with 100% schema coverage and an output schema present, the description plus structured data is fairly complete. It explains what the calendar contains and the schema documents all five parameters with defaults and bounds. The only missing piece is usage routing, which is scored separately under usage guidelines.

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 the baseline is 3. The description references the domain concept of '七大选题支柱' (seven topic pillars) which could inform the category parameter, but it never explicitly ties description content to any parameter. It adds no syntax or format details beyond what the schema already documents.

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 ('生成一个滚动内容日历' – generate a rolling content calendar) and enumerates exactly what it produces: seven topic pillar rotation, hook/CTA/tag suggestions, and sales event reminders. This clearly distinguishes it from siblings hook_framework and platform_playbook, which focus on single dimensions (hooks, platform playbooks) rather than a full calendar.

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 zero guidance on when to use this tool versus alternatives. No mention of prerequisites, exclusions, or how it relates to the sibling tools hook_framework and platform_playbook. An agent must infer the boundary between generating a calendar and using the hook or platform playbook tools.

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