observability_grafana_dashboards_card

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

With no annotations, the description carries the full burden, and it does declare the read-only trait plus the fact that it produces a prefab card. It says nothing about what happens if Grafana is unreachable, whether it performs a live fetch, or what the returned markup contains. Adequate but thin for a zero-annotation tool.

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 sentence with the resource and the read-only property front-loaded; nothing is wasted. It is arguably under-specified rather than over-long, but structurally clean.

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?

There is no output schema, so the description is the only source for what the caller gets back; 'prefab card' is not explained and the return shape (rendered UI vs. data) is left to inference. For a trivial read-only card this may be enough, but an agent cannot predict the response structure.

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 no parameters, so the baseline is 4. Nothing in the description needs to explain arguments, and it correctly implies no user input is required.

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 resource (Grafana dashboard list) and the output form (prefab card), which is enough to distinguish it from manage_grafana_dashboards. It does not explicitly contrast with the sibling, but the noun phrase is unambiguous.

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 guidance on when to use this card versus manage_grafana_dashboards, agentic_observability_workflow, or the other observability_*_card tools. The only implicit signal is '(read-only)', which hints at view-only use but does not state alternatives or exclusions.

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