functions_get_function

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

No annotations are provided, so the description must disclose behavioral traits. It only states the action ('Get details') without clarifying that the operation is read-only, has no side effects, or requires authentication. The description is insufficient for safety assessment.

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 concise sentence with no wasted words. It is front-loaded with the verb. While more detail could be added without harming conciseness, it is not overly terse.

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 simple retrieval tool with an output schema (present) and only 2 parameters (1 required), the description is minimally adequate. However, it could mention the read-only nature or that it returns full details, which are not yet available in structured data.

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 schema covers 100% of parameters with descriptions. The description adds 'by ID', which aligns with the required 'function_id' parameter, but does not provide additional semantics beyond what the schema already states. Baseline of 3 is appropriate.

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 uses the specific verb 'Get details' and identifies the resource 'a single function by ID'. It clearly distinguishes from sibling tools like 'functions_list_functions' which lists multiple functions, and 'functions_get_namespace' which is for a different resource.

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 retrieving a specific function, but does not provide explicit guidance on when to use this tool versus alternatives (e.g., 'functions_list_functions' to find IDs first, or 'functions_get_namespace' for namespace details). No exclusion criteria or context hints are given.

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