Add Database Connection

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

Annotations already declare readOnlyHint=false, idempotentHint=false and destructiveHint=false, so the safety profile is covered. The description adds that the connection is root-constrained and can be made the default geodatabase, but says nothing about permission requirements, behavior when the connection already exists, or validation of the database path.

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 front-loaded sentence with no wasted wording; the core action and its constraints come first. It is efficient, though brevity contributes to the parameter-coverage gap.

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?

An output schema exists, so return values need not be described, and annotations carry the mutation/safety profile. However, for a mutation tool with 4 parameters at 0% schema coverage, the description is too thin to tell the agent how to supply aprx_path, database_path, and validate correctly.

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 carry parameter meaning, yet it only obliquely references make_default via '可设为默认地理数据库' and never explains aprx_path, database_path, or validate. With four undocumented parameters, the description leaves a substantial gap.

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+resource ('追加一个数据库连接' = append a database connection) and adds scope ('受输入根约束' = constrained by the input root) plus an optional effect (can be default geodatabase). It separates add from remove via the sibling name, but does not differentiate itself from the closely related arcgis_pro_create_db_connection.

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?

No statement of when to use this tool versus alternatives such as arcgis_pro_create_db_connection or arcgis_pro_add_folder_connection, and no prerequisites or exclusions are given. The agent must infer usage from the name alone.

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