install_agent_pack

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

With no annotations provided, the description must disclose behavioral traits, but it only states the action without mentioning side effects, permissions, or return behavior. Installing templates could overwrite existing configurations or have other consequences, which are not disclosed.

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 a single, clear sentence with no filler or repetition. It is front-loaded with the key action and resource, making it easy to parse.

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 tool is simple with two well-described parameters, so the description covers the basic purpose. However, without an output schema, it does not hint at what happens after installation (e.g., success message, installation progress), leaving some gap in 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?

Input schema coverage is 100% and provides descriptions for both parameters. The tool description adds minimal extra meaning beyond the schema, though it helps contextualize that packName refers to marketplace templates.

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 uses a specific verb ('Install') and resource ('pre-built agent templates') with a source ('marketplace'), clearly distinguishing it from sibling tools like create_agent or list_agents. It precisely conveys what the tool does.

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 when to use the tool (when you want to install pre-built templates) but does not provide explicit guidance on when not to use it or mention alternatives like create_agent for custom agents. No exclusions or comparison with siblings.

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