wecom_set_seq

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

No annotations are provided, so the description carries full burden. It discloses that the tool sets the seq for message pulling, but does not mention side effects (e.g., overwriting previous seq, affecting future pulls), authentication needs, or error states. This is insufficient for a mutation tool.

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 sentence that efficiently conveys purpose and use case. It is front-loaded with the verb and resource, with no wasted words.

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?

Despite having an output schema (not shown), the description lacks details on return values, failure modes, prerequisites, or behavioral implications of setting the seq. For a tool that modifies state, more context is needed to ensure safe and correct usage.

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 coverage is 100% with the parameter 'seq' described as '新的 seq 值' (new seq value). The description adds context that seq is for message pull starting point, but offers no additional meaning beyond the schema's description. Baseline 3 is appropriate.

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 clearly states the verb '设置' (set) and the resource '消息拉取起始 seq' (message pull starting seq), and explains the purpose: resetting or skipping historical messages. This distinguishes it from siblings like wecom_get_seq (get) and wecom_pull_messages (pull).

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 implies usage for resetting or skipping historical messages, but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternative tools. The agent can infer context but lacks clear directives.

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