dump_region

Dump a named memory region to a file. Obtain region names with list_memory_regions.

Instructions

Dump a named memory region. Use list_memory_regions for names.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

B3/5.0

Behavior2/5

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

No annotations exist, so the description must cover behavioral traits. It only states the basic function without disclosing side effects (e.g., file overwrite), error conditions, or safety implications. Minimal transparency.

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?

Extremely concise: one sentence and a helpful hint. No redundant information. Front-loaded with action and subject.

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

Completeness2/5

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

Given no schema descriptions and no output schema, the description leaves many details undocumented: region format, file path specifics, return behavior, and error handling. Not sufficient for a complete understanding.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It implies that 'region' is a named memory region from list_memory_regions, and 'file_path' is likely an output file, but no format, constraints, or examples are given.

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

Purpose4/5

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

The description clearly states the action ('dump') and the subject ('named memory region'). It distinguishes from list_memory_regions by explicitly referencing it. However, it does not differentiate from sibling dump_memory, which may lead to confusion.

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?

Provides a hint to use list_memory_regions to get region names, which is helpful. But lacks guidance on when to use this tool versus alternatives like dump_memory or read_memory, and no exclusions or prerequisites beyond that hint.

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