deals_list_participant_updates

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

Discloses caching behavior ('Cached for 5 minutes'), which is useful. However, without annotations, the description should also indicate safety (read-only) and any side effects – these are missing.

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?

Description is clear and well-structured with workflow tips and use cases, but slightly verbose. Could be trimmed without losing clarity.

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?

No output schema, and the description does not detail the return format (e.g., fields in the changelog). For a list tool, more context on response structure would be helpful, though complexity is low.

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?

Only one parameter 'id' with schema description 'ID of the deal'. The description does not add additional meaning beyond what the schema already provides. Schema coverage is 100%, so baseline 3 is appropriate.

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?

Clearly states 'List updates about participants of a deal' and specifies it returns a changelog. Distinguishes from sibling tools like deals_list_participants (current participants) and deals_list_updates (general updates).

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?

Provides workflow tips and common use cases, but does not explicitly exclude alternative tools or provide when-not-to-use guidance. Lacks explicit differentiation from closely related siblings.

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