Getting the URL for agent installation

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

Annotations already declare the tool as readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description's behavioral disclosure burden is lower. Description adds the permission requirement 'Perm: manage_endpoints' and the prerequisite of agent installation. It does not contradict annotations. While useful, it does not provide significant new behavioral insight beyond what annotations and schema provide.

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 brief (two sentences) and front-loads the main action. The first sentence repeats the title, which could be eliminated for conciseness, but overall the text is efficient and every sentence serves a purpose: stating the action and providing prerequisite context.

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?

Given the tool has 4 parameters, a rich annotation set, and an output schema, the description adequately states the overall purpose and prerequisite. However, it does not mention that the URL varies by install_type (e.g., WindowsMSI, MacPKG, LinuxDEB) or that org_id may be optional. With the openWorldHint annotation, the agent can infer dynamic scope, but some additional context about the output or usage scenarios would improve completeness.

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 baseline is 3. The description does not add any additional meaning or elaboration on the parameters (org_id, verbose, install_type, response_format). It neither explains their purpose nor provides examples. Thus, no added value beyond the schema.

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?

Description clearly states 'Getting the URL for agent installation', which is a specific verb+resource. It explains the prerequisite (agent must be installed to manage endpoints) and mentions required permission. However, it does not differentiate from the sibling tool action1_get_windows_deployer_url, which might be an alternative for Windows-specific deployment. Overall clear but lacks sibling distinction.

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 context: 'In order to manage an endpoint, the Action1 agent needs to be installed on it first.' This suggests the tool should be called before endpoint management. However, no explicit guidance on when to use vs. alternatives like action1_get_windows_deployer_url, nor when not to use. Usage is implied but not explicit.

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