extract_memray

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

Annotations provide minimal safety info (all hints false), and the description does not add behavioral context such as side effects, return format, or requirements. 'Through Memray's public FileReader' is an implementation detail rather than behavior.

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 a single sentence, but the phrase 'through Memray's public FileReader' is unnecessary for operational use and the vagueness of 'supported memory concepts' reduces clarity. It is concise in length but under-specified.

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 one required parameter, no parameter documentation, and no usage guidance, the description leaves the agent with insufficient information to select and invoke the tool correctly. The presence of an output schema reduces the need for return-value docs, but other aspects are lacking.

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 single parameter run_id has no schema description, and the tool description does not mention what run_id refers to or how to obtain it. There is zero parameter guidance.

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 uses the specific verb 'Extract' and identifies the Memray source, which differentiates it from sibling extraction tools targeting other profilers. However, 'supported memory concepts' is vague and does not enumerate what concepts are included.

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 no guidance on when to use this tool compared to other extract_* tools or alternatives. It lacks any contextual trigger or prerequisite (e.g., needing a Memray file).

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