observability_capabilities_card

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

No annotations are provided, so the description carries the full behavioral burden, yet it says nothing about what the card contains, whether it is read-only, or what form the output takes. The word "card" weakly implies a static read-only summary, but that is inference, not disclosure.

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?

A single short phrase with no filler, but its brevity comes from under-specification rather than tight writing. The key noun phrase is front-loaded but opaque.

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?

With no output schema, no annotations, and no parameter documentation, the description is the only source of information about what the agent gets back, and it does not say. An agent cannot predict the response content or decide when this card is the right one.

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?

The tool takes zero parameters, so there is nothing for the description to explain beyond what the empty schema already conveys. Baseline 4 applies.

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?

"Prefab card: SOTA manifest and tool surface summary" restates the tool name with jargon rather than stating a concrete action. "Prefab card" and "SOTA" are undefined, and nothing distinguishes it from sibling card tools like observability_stack_health_card or observability_grafana_dashboards_card.

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 indication of when to call this versus the two sibling "_card" tools or the many status/monitoring tools. The agent must guess its place in the observability surface.

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