noark5_list_children

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

With no annotations, the description carries the full behavioral burden. It discloses that discovery is HATEOAS-based, that available child collections are auto-discovered and each type is fetched, and that the result is a grouped list or an error message. It does not mention pagination or the number of requests caused by fetching each type, but the core behavior is transparent.

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?

The description is compact and well-structured: summary, usage modes, Args, and Returns. Every sentence adds value, and the most important behavioral distinction is front-loaded.

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 two-optional-parameter tool with an output schema and no annotations, this description is nearly complete: it explains the discovery mechanism, parameter semantics, and return shape. The main gap is the slightly misplaced upward-traversal reference and lack of pagination detail, but an agent can invoke it correctly.

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 property descriptions are 0% covered, but the Args section fully compensates: parent_url is explained as the self-href URL and omit for top-level, and filter_str is explained as an optional OData $filter applied to each collection. Both parameters receive meaningful, actionable 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 opens with 'List all children of an entity using HATEOAS discovery,' which is a specific verb and resource. It then clarifies the two modes (top-level listing without parent_url, child collections with parent_url), so the agent can distinguish this from upward-traversal and search tools.

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?

It explicitly states when to omit parent_url (top-level entities) and when to supply it (children of a specific entity). It also references upward traversal via noark5_navigate_up, giving an alternative cue, though that tool name does not appear in the sibling list and noark5_list_parents would be the clearer pointer.

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