List DM conversation events

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 states 'Read' (no side effects) and 'recent' (temporal scope), adding some transparency. However, it does not disclose ordering, pagination, or other behavioral traits like what happens with invalid IDs or how maxResults interacts with 'recent.' These gaps make the transparency adequate but incomplete.

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, front-loaded sentence with no filler. It quickly communicates the action, resource, and scope. Every word contributes value, making it exceptionally concise 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?

The tool is simple with only two parameters (one required), no output schema, and no nested objects. The description covers the core purpose and scope, and the schema covers all parameters. Minor omissions like return format and pagination are not critical for this tool's complexity, so the description is mostly complete with only minor gaps.

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?

Schema description coverage is 100%, so the baseline is 3. The description adds the phrase 'by conversationId' which reinforces the role of conversationId, but it provides no new meaning beyond the schema. It does not explain how maxResults affects results, which is already in the schema. Thus the description adds marginal value over 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 action ('Read'), resource ('DM events'), and scope ('in a conversation by conversationId'). It also distinguishes from sibling tools by specifying per-conversation and supporting both group and 1:1 threads, which differentiates it from broader tools like list_dm_events.

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 makes the usage context clear: use it when you have a conversationId and need recent events for that specific conversation. It does not explicitly mention alternatives or when not to use this tool, but the context is unambiguous and does not require exclusions.

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