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

With no annotations provided, the description carries the behavioral burden. It does disclose a meaningful side-effect: the tool does not send messages ('不发送消息'). However, it does not explain overwrite behavior for an existing alias, idempotency, persistence, or error handling when the session does not exist.

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 two short sentences with no filler. The primary action is front-loaded, followed by a usage note and a valuable negative disambiguation. Every sentence earns its place.

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 bind action, the core invocation context is present. But with no annotations, no output schema, and 0% per-parameter schema descriptions, the description omits return behavior, alias-collision semantics, and error conditions. It is adequate but has clear gaps.

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 0%, so the description must compensate. It partially does: '对话' maps to sessionId, '目录' maps to cwd, '固定别名' maps to alias, and 'Codex/Claude' connects to the app enum. However, the enum value 'dsh' is unexplained, and the source/format of sessionId and cwd are not specified.

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 uses a specific verb ('bind'), names the resources ('existing conversation' and 'directory'), and the target ('fixed alias'). It also distinguishes the tool from siblings: '不发送消息' separates it from talk_send, and '已有对话' differentiates it from talk_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 second sentence gives a concrete trigger: use the tool to bind the Codex/Claude conversation that initiated the current task. It does not explicitly name alternatives or state when not to use the tool, but it provides clear enough context for an agent to decide.

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