A3.6/5.0
Behavior2/5

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. It says 'Lists' which implies a read-only action, but it does not mention authorization requirements, pagination behavior, response format, or any potential side effects. For a system-level permission listing, an agent would benefit from knowing if admin privileges are required or if the API is deprecated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is direct and front-loaded with the action. However, the '[Tool Role]:' prefix is redundant and adds no informational value, slightly detracting from conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (zero params, output schema exists), the description is a minimal but viable starting point. It covers what the tool lists and the API version, but it omits any mention of authentication or the read-only nature, which are relevant for a permissions-related tool. The output schema probably describes return values, so that is not required, but additional context about access control would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema is empty and the description explicitly says 'all permissions', confirming no filters. With 0 parameters, the schema already provides complete coverage, and the description reinforces the unqualified scope. No additional parameter semantics are needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Lists' and the resource 'all permissions available in the Airflow system', along with an explicit version constraint '(v1 API only)'. This distinguishes it from sibling list tools like list_roles and list_plugins, which target different objects.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage: use this tool to list permissions. However, it does not explicitly state when to use it versus alternatives, nor does it provide any exclusion criteria. The 'v1 API only' note gives some context but doesn't name alternative tools for v2 or other scenarios.

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