get_session_ids

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

No annotations are provided, so the description carries the full burden. It adequately states the tool returns session ids and describes parameters, but does not disclose any behavioral traits (e.g., side effects, permissions, rate limits). The description is correct but could be enhanced.

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 concise with a clear first paragraph and bullet-style parameter explanations. Every sentence adds value, with no wasted words.

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 presence of an output schema (context shows has output schema: true), the description need not detail return values. It covers purpose, usage guidance, parameters, and differentiation from siblings, making it fully complete.

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?

Input schema has 0% description coverage, so the description must compensate. It explains all four parameters: 'website_id' (from 'get_websites'), 'start_at' and 'end_at' (UTC), and optional 'event_name' with example. This adds significant value beyond the 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 tool gets unique session ids in a range, optionally filtered by event. It distinguishes from siblings like 'get_tracking_data' (inspection) and 'get_website_stats' (counting). The verb 'Get' and resource 'session ids' are 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.

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

The description explicitly guides when to use the tool: for finding sessions to inspect with 'get_tracking_data', not for counting visitors (use 'get_website_stats'). It also explains the optional 'event_name' filter and when to omit it.

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