open_ticket_tool

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 clearly states the state change (from new to open) and the optional ownership assignment, which are the core effects. It does not detail error handling, permissions, or prerequisites beyond the implied 'new' status, but for a simple state-transition tool this is reasonably transparent.

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 sentence that front-loads the primary action and immediately clarifies the state transition and optional side effect. There is no filler or redundant information; every phrase contributes to understanding the tool's purpose and behavior.

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 simplicity (2 parameters, one required) and the presence of an output schema, the description provides adequate context. It states the exact status change and optional ownership. It lacks explicit commentary on edge cases (e.g., if the ticket is already open) and does not differentiate from overlapping sibling tools, but overall it is sufficiently complete for a straightforward mutation tool.

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 100%, and both parameters are well-described: ticket_id as the ID number and owner as an optional username. The description's phrase 'optionally taking ownership' adds semantic context to the owner parameter but does not go beyond what the schema already states. Since the schema covers parameter meaning fully, the 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 clearly states the action: 'Open a ticket (change status from new to open), optionally taking ownership.' It specifies the resource (ticket), the specific state transition (from new to open), and an optional secondary action (taking ownership). This distinguishes it from generic status tools like set_ticket_status_tool by narrowing the exact 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?

The description implies usage: when you want to open a ticket and optionally take ownership. However, it does not explicitly address when to use this over the overlapping sibling tools such as set_ticket_status_tool or take_ticket_tool, nor does it provide exclusions or alternative guidance. It offers clear context but no explicit alternatives.

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