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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that this returns 'Nodes and connections' of a specific graph shown on a page, which is useful behavioral context, but it does not describe return shape, size, or whether traversal is needed.

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?

It is a single short fragment with no wasted words, but it is under-specified rather than deliberately concise. The key information is front-loaded, yet the fragment lacks a clear subject-verb structure that would make it self-contained.

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 read-only tool with no output schema, the description is adequate but thin: it says the tool relates to graph nodes and connections shown on /holding-group, but it does not explain what the response contains or how an agent should interpret it. No output schema exists, so the description carries more burden than it currently meets.

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 and the schema is empty, so there are no parameter semantics to explain. The baseline for zero parameters is 4, and the description does not need to compensate for missing schema details.

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 names the resource ('Nodes and connections of the Ecosistema Dadaville graph') but is a noun phrase with no verb, so the action is only implied by the tool name get_ecosistema. It gives a page context ('/holding-group') but does not explicitly distinguish this tool from siblings like get_page or list_pages.

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 offers no when-to-use guidance, no conditions for choosing this over alternatives, and no prerequisites. It merely states what data belongs to the graph, leaving the agent to infer the appropriate call context.

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