configure_account

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

With no annotations provided, the description carries the full burden and discloses three behavioral traits: auth_secret is sensitive and requires user consent before writing, the configuration takes effect immediately after writing, and it persists to .env. It stops short of describing overwrite/re-run behavior or connection validation, but the key side effects and consent requirement are stated explicitly.

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-loads the purpose and then chains when-to-use, the consent requirement, and the persistence effect without filler. Every clause earns its place, making the description informative yet compact.

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?

The description covers purpose, invocation timing, secret sensitivity, immediate effect, and persistence, while the output schema handles return values. However, it leaves parameter semantics largely undocumented and does not state what happens when the tool is re-run over an existing configuration, which is relevant for a persistent config tool.

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 for the 10 parameters, but it only provides a coarse IMAP/SMTP grouping and flags auth_secret as sensitive. Parameters such as sent_folder, auth_mode, imap_port/smtp_port defaults, and the ssl booleans remain unexplained, leaving an agent to guess at their meaning.

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 states a specific verb and resource: '配置邮箱账号（IMAP/SMTP 凭据）' (configure email account with IMAP/SMTP credentials). This clearly scopes the tool to initial account setup, which no sibling such as test_email_connection, get_account_status, or get_account_info covers.

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 explicit when-to-use context: '首次运行或配置缺失时调用' (call on first run or when configuration is missing). It does not name alternatives or exclusions, but none of the 29 siblings performs configuration, so the guidance is sufficient for an agent to select this tool at setup time.

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