connect

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

No annotations are provided, so the description carries the full burden. It discloses that the tool establishes a connection, specifies the return value ('Connection status message with TRACE32 version info'), and lists configurable parameters. However, it does not mention whether the connection is persistent, any side effects, or error behavior, which would be helpful.

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 concise with a clear structure: a one-line summary, then an Args section listing parameters with defaults, and a Returns section. All information is functional with no fluff. However, the 'Args' and 'Returns' formatting is slightly verbose for an MCP description, but still efficient.

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 that this is a connection tool with 3 parameters and an output schema, the description adequately covers the purpose, parameters, and return value. The presence of sibling tools like 'disconnect' and many operational tools provides context, and the description aligns well. It could benefit from mentioning that connection is required before using most other tools, but the name and purpose make that implicit.

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?

The input schema has 0% description coverage (no descriptions in the schema), but the tool description provides clear docstrings for each parameter: node (host address, default from config or 'localhost'), port (API port, default from config or 20000), protocol (TCP or UDP, default from config or 'TCP'). This adds significant meaning beyond the schema's bare defaults.

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 purpose: 'Connect to a running TRACE32 PowerView instance.' The verb 'connect' combined with the specific target 'TRACE32 PowerView instance' leaves no ambiguity. It is distinct from sibling tools like 'disconnect' and other operational tools.

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?

While the description implies usage as an initial setup step before other TRACE32 operations, it does not explicitly state when to use this tool versus alternatives (e.g., 'disconnect' for teardown). No prerequisites or when-not-to-use conditions are provided, but the context of siblings suggests it is the entry point.

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