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 mentions the tool is for listing raw log data, implying a read-only operation, but does not specify permissions, rate limits, or response format details. The description adds some context about data analysis use but lacks comprehensive behavioral traits like pagination or error handling.

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 front-loaded with the core purpose in the first sentence and adds a concise usage guideline in the second. Both sentences earn their place by providing clear value without redundancy, making it efficient and well-structured.

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 tool's complexity (7 parameters, no output schema, no annotations), the description is moderately complete. It covers purpose and usage but lacks details on behavioral aspects like response format, error cases, or prerequisites. Without annotations or output schema, more context on what the tool returns would be beneficial for full completeness.

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 schema description coverage is 100%, so the schema already documents all 7 parameters thoroughly. The description does not add any parameter-specific semantics beyond what the schema provides, such as explaining interactions between parameters or default behaviors. Baseline 3 is appropriate as the schema handles parameter documentation adequately.

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 ('Lists') and resource ('logs/recordings') with specific scope ('within a date/time range'). It distinguishes from siblings by emphasizing raw log data for analysis, unlike tools like 'limitless_get_lifelog_by_id' (single log) or 'limitless_list_lifelogs_by_date' (date-specific).

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 clear context for when to use this tool ('Best for getting raw log data which you can then analyze for summaries, action items, topics, etc.'). However, it does not explicitly state when not to use it or name specific alternatives among the siblings, such as 'limitless_list_recent_lifelogs' for recent logs without date ranges.

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