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

With no annotations, the description carries the burden, and it does add one genuinely useful behavioral fact: a 403 can occur when the tenant permits GET only, telling the agent this is a privileged write. It says nothing about reversibility, side effects on existing bundles, or what a successful creation yields.

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 filler; the caveat is parenthetically attached rather than buried. It is efficient, though the terseness contributes to the gaps elsewhere.

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 mutation tool with zero annotations, no output schema, and zero required parameters (unusual for a create), the description should explain what a bundle is, what happens when bundle_name or primary_app_id are omitted, and what comes back. It covers only the failure mode.

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 all three parameters (bundle_name, primary_app_id, notification_message) are already documented in the schema. The description adds no additional semantics such as defaults or what happens when a parameter is omitted, so the baseline 3 applies.

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?

States a specific verb and resource ('Create ASC app bundle'), which clearly separates it from read-side siblings like list_app_bundles or get_app. It does not name any sibling explicitly, so it lands just short of a 5.

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?

There is no statement of when to use this versus list_app_bundles or create_app, and no prerequisites are given. The only guidance is an implicit 'this may fail' caveat, which is not a usage rule.

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