generate_card

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

Annotations are absent, so description must disclose behavior. It states creation of a file but omits side effects like overwriting, permissions, or error conditions. No mention of output location or success/failure signals.

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 short paragraphs plus a bullet list of parameters. No wasted words, but could be more front-loaded with key purpose. The German sentence is redundant but not harmful.

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?

Despite 10 parameters and no annotations, the description lacks behavioral context (side effects, prerequisites). Output schema exists but return values still require understanding. Missing guidelines on when to invoke.

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%, so description must explain parameters. It lists all 10 parameters with brief comments, but most are translations or minimal definitions. Adds format hint for 'tools' but overall meaning is shallow, not deep semantics.

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 generates a .well-known/mcp-server-card.json for MCP servers, with specific verb 'generate' and resource 'server card'. It distinguishes from siblings like discover or validate_card by focusing on creation of metadata file.

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 explicit guidance on when to use this tool versus alternatives like discover or validate_card. The description mentions agents use the card for discovery but does not compare or provide exclusion criteria.

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