ise_ers_get_node

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description states the read operation but doesn't disclose what happens with an invalid/nonexistent ID (does it 404? raise an error?), whether the response format is consistent across node types, or any specifics about what fields are returned. For a get operation with no annotation coverage, this is notably thin.

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 a single, efficient sentence that conveys purpose without excess. The deployment parameter's detailed explanation lives in the schema where it belongs. No wasted words, appropriately minimal for a simple getter.

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 single-resource get with 2 params and no output schema, the description is reasonably adequate. However, the lack of behavior specification (error handling, response shapes) given zero annotations and no output schema means the agent has limited expectations about what will happen. The deployment parameter guidance compensates partially, making this acceptable but not complete.

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 50% - the 'deployment' parameter is well documented with name/slug/number examples and instruction to call ise_list_deployments. The 'id' parameter has no schema description but 'by ID' in the tool description gives basic context. The deployment parameter is thoroughly explained, adding substantial value beyond the bare schema.

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 'Get a single ISE Nodes object by ID' clearly states the verb (get), resource (ISE Nodes object), and the identifier key (by ID). It distinguishes from siblings like ise_ers_list_node (which fetches all nodes) and ise_ers_search_node (which searches), though it does not explicitly name those distinctions.

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 implies usage for fetching a single node by ID, but provides no explicit guidance on when to prefer this over ise_ers_list_node or ise_ers_search_node. The deployment parameter description does add useful context ('Omit to use the only/default deployment. Call ise_list_deployments to see the choices'), but overall the when-to-use vs alternatives is only implied, not explicit.

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