heap_info

Retrieve a quick heap usage summary for a Java process, showing capacities, used, and committed regions without requiring a full heap dump.

Instructions

Brief heap usage summary: capacities, used, committed regions. Quick snapshot without full dump.

Behavior2/5

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

No annotations are provided, so the description carries full responsibility. It does not disclose whether the operation is read-only, requires permissions, or any side effects. The phrase 'quick snapshot' hints at non-destructiveness, but this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single concise sentence that front-loads the key information (brief heap usage summary) and includes distinguishing detail ('without full dump'). No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (single parameter, no output schema, no nested objects), the description adequately hints at the output (capacities, used, committed). It provides enough for a quick snapshot context, though more detail on return format would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with the parameter 'pid' already described in the schema as a required integer. The description adds no further parameter semantics beyond the schema's existing explanation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool provides a 'brief heap usage summary' covering capacities, used, and committed regions. It distinguishes itself from a 'full dump', making its purpose specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for a quick overview ('quick snapshot without full dump') but does not explicitly state when to use this tool over sibling tools like heap_dump or heap_histogram. No exclusion criteria or alternative suggestions are given.

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