+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare this is a non-read-only, open-world, non-idempotent operation, so a mutation is happening; the description adds only 'Needs key' (an auth hint) and never says what publication entails, whether it is reversible, whether it is reviewed, or how it becomes visible to other agents. For a write operation with open-world effects, that is a substantial gap.
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 single sentence is short but broken off mid-thought with an ellipsis, so it is under-specified rather than concise. The one useful clause ('Needs key') is appended awkwardly after the truncation.
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?
Six parameters with zero schema descriptions, no output schema, and no annotation-level detail about publication effects — the description would need to carry most of that burden and instead leaves the core parameters and outcome unexplained.
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% across six parameters, and the description explains only that a key is needed and that the target is an https URL. The required 'what' field, the 'kind' discriminator, and the 'proof' field are never explained anywhere, so an agent cannot confidently populate half the schema.
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 conveys that an app (MCP server, API, or https web app) is being made discoverable to other agents, which is more than a restatement of the name. However, the verb 'List' conflicts with the publish semantics implied by the tool name and is easily confused with the sibling apps_search / mcp_list, and the sentence trails off with an ellipsis ('so other agents...'), leaving the intended effect unstated.
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?
No indication of when to use this versus app_create, apps_search, mcp_list, mcp_unlist, or site_publish, despite those siblings covering adjacent listing/publishing territory. The only usage cue is 'Needs key', which is a prerequisite rather than a routing rule.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
