apps_import

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

With no annotations provided, the description carries full burden for behavioral transparency. It details what is fetched, how the local app is created, and what is not handled (deps). It could be improved by mentioning error conditions or side effects beyond id conflict, but overall it's informative.

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 concise, using only a few sentences to convey the core action, side effects, and warnings. It is front-loaded with the primary purpose and avoids unnecessary fluff.

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 tool with 4 parameters and no output schema, the description is fairly complete. It covers input behavior, side effects (id conflict), and limitations (deps not installed). It does not specify the return value, but this is partly mitigated by the tool type (action) and lack of output schema.

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 coverage is 100% with descriptions for all 4 parameters. The description adds extra semantic value for registry_url (security context about allowlisting and SSRF) and implies the purpose of app_id. It does not repeat schema details verbatim, but enriches the understanding.

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 clearly states the tool's action: 'Install an app from the public registry onto this ComfyUI' and details the process of fetching and creating a local app. It distinguishes itself from sibling tools like apps_list, apps_get, apps_run by focusing specifically on importing.

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 provides important usage guidance: it warns about id conflict on re-import and notes that deps are not installed, requiring user action. However, it does not explicitly compare with alternative installation methods or state when not to use the tool.

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