debug.attach

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

No annotations are provided, so the description must disclose all behavioral traits. It only states 'Connect' but does not mention side effects (e.g., blocking, state changes, requirements for JVM flags), failure modes, or what happens if already connected. The timeout parameter is not explained.

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 extremely short (5 words), but this is under-specification rather than effective conciseness. It fails to convey essential information, so the brevity is detrimental to usability. The structure is lacking.

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 lack of annotations, output schema, and parameter descriptions, the description is severely incomplete. It omits return values, behavioral details, prerequisites, and interaction with sibling tools. A comprehensive description is needed for this complex connection 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 0%, and the description adds no meaning to any of the four parameters (allow_remote, host, port, timeout_ms). The agent must infer their purpose solely from names and defaults, which is insufficient for precise invocation.

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 'Connect to JVM via JDWP' clearly states the exact action (connect) and target (JVM via JDWP). It distinguishes this tool from sibling tools like debug.disconnect or debug.set_breakpoint, which serve different purposes.

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?

No usage guidance is provided. The description does not tell the agent when to use attach (e.g., before other debug operations) or when to avoid it (e.g., if already connected). Sibling tools like debug.disconnect imply a workflow, but no explicit advice is given.

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