summarize_time_range

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

No annotations provided, so the description must disclose behavioral traits. It mentions 'headless Claude analysis' but fails to indicate if the tool is read-only, modifies data, requires special permissions, or has side effects. The output format and any limitations are not described.

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?

A single, front-loaded sentence that clearly states purpose and method. Every word adds value; no fluff. Appropriate for a straightforward tool.

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?

With no output schema, the description should explain return values. It does not mention what the summary contains, its length, format, or how to interpret the result. Given 4 parameters and no output schema, the description is too brief to be fully actionable.

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 input schema covers 100% of parameters with descriptions, so baseline is 3. The description does not add significant meaning beyond the schema; it references 'headless Claude analysis' but that doesn't clarify parameter usage. The style parameter is well-documented in 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?

Description uses a specific verb 'Generate intelligent summary' and clearly identifies the resource 'conversations for a specific time range'. It distinguishes from sibling tools like summarize_daily_conversations by specifying it covers any time range, not just daily. The method 'headless Claude analysis' adds context.

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 implies the tool is for generating summaries of conversation over a period, but it does not explicitly state when to use this tool versus alternatives like list_sessions, search_conversations, or analyze_sessions. No when-not-to-use or prerequisite conditions are provided.

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