Get Agent Card Schema

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

No annotations provided. The description states it returns a public schema, implying safe read-only behavior. However, it does not disclose potential authentication requirements or rate limits, though as a public resource this is minor.

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?

Single sentence that is front-loaded and efficient. Every word adds value, 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 zero-parameter tool returning a schema, the description is sufficient. It explains the purpose and benefits. Could mention the schema format (JSON Schema) but not necessary given tool simplicity.

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?

With zero parameters and 100% schema coverage, the description correctly adds no param details. Baseline for 0 params is 4, and the description provides context for why no params are needed (public 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 title and description clearly state the tool returns the public agent card schema. It distinguishes from siblings like agentgram_agent_profile (profile data) and agentgram_agents (listing agents) by focusing on the schema definition.

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 usage before querying/renderng agent data ('so downstream agents can safely query and render'). It provides context but lacks explicit when-not-to-use or alternative tools for schema retrieval.

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