connect

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

Annotations already indicate the tool is not read-only, is open-world, is idempotent, and is non-destructive. The description adds the context of 'pinned local', which is a specific behavioral constraint, but does not disclose additional traits such as failure behavior when no endpoint is pinned. It does not contradict annotations.

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, well-structured sentence that immediately delivers the key information. There is zero wasted text, making it highly efficient and front-loaded.

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 simple zero-parameter tool with an output schema present, the description is largely complete. It conveys the essential target and action, but it could briefly mention that connecting is a prerequisite for many other operations or that a pinned endpoint must already exist, which would enhance completeness.

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 no parameters, so the schema is fully covered and the baseline is 4. The description adds semantic context by clarifying that the tool targets a pre-configured 'pinned local' endpoint, which is helpful beyond the empty schema.

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 uses a specific verb 'connect' and a clear resource 'pinned local PLAXIS endpoint', making the tool's purpose unambiguous. It distinguishes well from siblings like disconnect and connection_status, which serve adjacent but different functions.

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?

Usage is implied: to initiate a connection to the pinned local endpoint, but the description does not explicitly state when to use it versus alternatives or mention prerequisites like ensuring an endpoint is pinned. It lacks clear guidance on whether connection is required before other operations.

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