connect

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

No annotations exist, so the description bears full responsibility. It describes the action as connecting without detailing side effects, error handling, or state changes (e.g., if already connected). It mentions return values but lacks deeper behavioral context.

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 well-structured with a purpose statement, usage condition, parameter list, and returns. It is slightly verbose but efficiently front-loaded with critical information, earning a high score.

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 has an output schema and 5 parameters, the description is fairly complete: it covers purpose, prerequisites, parameters, and return values. Missing edge cases (like error states) are compensated by the output schema.

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?

With 0% schema description coverage, the description fully explains all 5 parameters: device (example models), interface (SWD/JTAG), speed (kHz), serial_no (multiple JLinks), ip_addr (over IP). It adds significant meaning beyond the 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 clearly states the tool connects a JLink debugger to a target microcontroller, and explicitly mentions it must be called before other debug operations, distinguishing it from sibling tools like 'disconnect' which are complementary.

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 provides explicit guidance: 'Must be called before other debug operations' and references sibling tool 'list_devices()' for device selection, offering clear when-to-use and alternative information.

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