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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is well covered. The description adds a meaningful behavioral promise beyond annotations: 'Never reveals AGENTPUB_API_KEY', plus the diagnostic/read-only framing, which helps an agent understand side-effect and secrecy expectations.

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?

Two compact sentences front-load the core purpose and then add the essential diagnostic and security caveats. Every sentence earns its place with no redundancy or filler.

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 0-parameter, read-only, idempotent introspection tool with an output schema, the description fully equips an agent: it names the target, states the diagnostic use case, and flags the secret-handling constraint. No critical behavioral or invocation detail is missing.

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?

This tool has zero parameters, so the schema trivially covers the entire interface. The description adds context about what objects are inspected (live native MCP descriptions/input schemas), which is useful even though no parameter documentation is needed.

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 ('Inspect') and resource: AgentPub's live native MCP descriptions/input schemas for discovery-related tools. It clearly distinguishes itself from the sibling agentpub_inspect_remote_tool_schema by scoping to live native schemas and discovery-related tools.

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?

Gives clear context: use this when you need to inspect live native MCP schemas for discovery tools, and labels it as diagnostic/read-only. It does not explicitly name alternatives such as agentpub_inspect_remote_tool_schema or explain when to prefer one over the other, so a small gap remains.

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