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

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals the 'clear' parameter's destructive behavior (clearing the log after retrieval) and the default limit, which are valuable. However, it doesn't mention permission requirements, rate limits, or what happens when filters conflict.

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 clear sections (Args, Returns) and efficiently explains the tool's functionality. Every sentence serves a purpose, though the initial purpose statement could be slightly more detailed to distinguish from siblings.

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?

For a tool with 5 parameters, 0% schema coverage, and no output schema, the description does an excellent job explaining parameters and return format. The main gap is lack of sibling differentiation, but otherwise it provides sufficient context for effective use.

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 compensates by explaining all 5 parameters in detail. It clarifies filter types ('api_call' vs 'prop_read'), substring matching behavior, the destructive 'clear' option, and default values. This adds significant meaning beyond the bare 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 verb ('Retrieve') and resource ('JSVMP interpreter execution log'), making the purpose unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'get_property_access_log' or 'get_console_logs', which appear to be related logging tools.

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 versus alternatives. With multiple logging-related sibling tools (get_property_access_log, get_console_logs, get_trace_data), there's no indication of which scenarios warrant this specific JSVMP log retrieval tool.

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