test_authentication

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

No annotations are provided, so the description carries the full burden. It discloses the core behavior (testing token validity) and return type (dictionary indicating status), but lacks details on error handling, rate limits, permissions needed, or what constitutes a valid token. It adds basic context but misses richer behavioral traits for a tool with no annotation coverage.

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 front-loaded with the core purpose in the first sentence, followed by a brief return statement. Both sentences earn their place by clarifying functionality and output without waste. It is appropriately sized for a simple tool with no parameters.

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?

Given the tool's low complexity (0 parameters, no output schema, no annotations), the description is minimally complete. It covers the purpose and return type, but for a tool with no structured data, it could benefit from more detail on authentication context or error cases. It's adequate but has clear gaps in behavioral disclosure.

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 has 0 parameters with 100% schema description coverage, so no parameter information is needed. The description appropriately does not discuss parameters, maintaining focus on the tool's purpose and output. This meets the baseline for zero parameters, as it avoids unnecessary 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 clearly states the specific verb ('Test') and resource ('current authentication token'), and distinguishes it from siblings like 'complete_authentication', 'force_reauthenticate', and 'get_authentication_info' by focusing on validation rather than completion, enforcement, or information retrieval. It directly answers what the tool does without redundancy.

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 when checking token validity, but does not explicitly state when to use this tool versus alternatives like 'get_authentication_info' or 'force_reauthenticate'. It provides context (testing authentication) but lacks guidance on prerequisites, exclusions, or specific scenarios for selection among siblings.

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