fork_repository

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action and destination but does not mention potential side effects (e.g., behavior if a fork already exists), authentication requirements, or that forks can be created for organizations (although the schema hints at this).

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, clear sentence with no unnecessary words. However, it is under-specified for a tool with three parameters and no annotations, so the brevity comes at the cost of completeness. It is not a tautology like 'Process', but it leaves out valuable context.

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?

This is a mutation tool with no annotations and no output schema. The description fails to explain key aspects such as return values, error conditions, the effect of the 'organization' parameter, or whether the operation is idempotent. It is minimally sufficient to recognize the tool's purpose but not complete enough for safe autonomous invocation.

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 low (only the 'organization' parameter has a description). The tool description adds no meaningful semantics for the required 'owner' and 'repo' parameters, and it does not compensate for the missing schema descriptions. The phrase 'to your account' vaguely relates to the 'organization' optional parameter but is insufficient.

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 tool's function: 'Fork a repository to your account' uses a specific verb and resource. It is unambiguous, though it does not explicitly differentiate from similar tools like sync_fork, which is a distinct operation.

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?

There is no guidance on when to use this tool versus alternatives such as sync_fork or create_repository. The description simply states what the tool does without any context on appropriate scenarios or exclusions.

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