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

No annotations are provided, so the description carries the full disclosure burden. It says nothing about required permissions, whether deployment is asynchronous, what happens on duplicate deploys, or whether the app is started automatically. The only behavioral hint is that the array arguments are optional-in-practice, which overlaps with parameter semantics rather than tool behavior.

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?

Three short sentences, each doing distinct work: the action, the id-source routing, and the optionality guidance. Front-loaded with the core verb and resource, no filler or repetition.

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?

This is a mutating, multi-argument deployment tool with no annotations and no output schema, so the description should say more than it does. It omits return/result expectations, async or timing behavior, failure modes, and the meaning of the three array parameters, leaving real gaps for an agent deciding how to invoke it.

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 supply all parameter meaning. It explains application_id's dual source well, but territory_id is never described, and mount_points, deploy_settings and configurable_env_vars are lumped together as "advanced arrays" with no indication of what each configures. Only one of five parameters is genuinely clarified.

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 first sentence gives a specific verb and resource ("Deploy a managed application onto a territory"), which is clearer than most siblings. It also disambiguates the application_id argument by naming the two id sources (catalog via list_available_apps vs. custom via create_custom_app). It does not, however, distinguish deployment from adjacent lifecycle siblings like start_app or get_app_definition.

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?

Two useful triggers are implied through sibling references: use list_available_apps to obtain a catalog id and create_custom_app to obtain a custom definition id. The closing sentence also advises omitting the advanced arrays unless needed. There is no statement of when to choose this over start_app/check_app_status or what prerequisites must hold before deploying.

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