octo_get_extensions

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

No annotations are provided, so the description carries the behavioral burden. 'List' clearly indicates a non-mutating read operation, which is useful, but the description does not disclose additional behavioral aspects such as team scope semantics, empty-result behavior, or whether any authorization is required.

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, front-loaded sentence that conveys the operation, the resource, and the relevant output fields with no filler or redundancy.

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 zero-parameter read-only listing tool with an output schema available, the description is sufficient. It names the resource, the intended scope ('team's'), and the key returned fields, so an agent has enough context to 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?

There are zero parameters, so parameter semantics are trivially complete. The description adds value by specifying the output fields (name, version, UUID), and schema coverage is 100% because there are no properties to document.

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 states a specific verb ('List'), a specific resource ('the team's browser extensions'), and the data returned ('name, version and UUID'). This clearly distinguishes it from sibling tools like octo_delete_extensions, which performs a mutation.

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 this tool is for retrieving an inventory of browser extensions, but it does not explicitly state when to use it versus alternatives or when not to use it. The context is reasonably clear, but there is no explicit routing guidance relative to sibling tools.

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