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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the description needn't restate safety. But it adds nothing either: it does not indicate which of the 19 actions are destructive versus read-only, what permissions or prerequisites apply, or what side effects buy/license/publish have. For a multi-action destructive tool, that leaves behavior opaque.

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?

It is a single, front-loaded sentence with no filler prose, which is structurally clean. However, a comma-separated verb dump conveys little actionable information per word, so brevity comes at the cost of usefulness rather than being true conciseness.

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 complex, 19-action, destructive, open-world tool with a nested undocumented params object and no output schema. A one-line verb list provides nowhere near enough information for an agent to call it correctly or safely.

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%, and the 'params' object (nested, untyped) is entirely undocumented in both schema and description. The description's verb list hints at some action values but never explains how to populate params for any specific action, so it does not compensate for the coverage gap.

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 names a domain (miniapps and their mods) and enumerates verbs (publish, deploy, buy, license, compose) that loosely map to the action enum. However, it is a flat verb list covering 19 heterogeneous operations, so an agent cannot tell which capability is the core purpose or how it differs from siblings like miniapp_brain or handoff_artifact.

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 guidance on when to use this tool versus alternatives, nor on which action to pick for a given intent. With 19 enum values spanning reads (list, get_mods, get_terms) and destructive writes, the absence of any routing guidance is a significant gap.

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