list_deployment_activity

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

With no annotations, the description carries the full burden, and it does add a genuinely useful behavioral trait: output is automatically stored, returned as a preview with an @obj_ ID, and can be fed to object-store tools or other functions. However, it says nothing about permissions, result limits, or event types beyond 'activation and revision activity'.

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 core purpose leads, but the body mixes docstring-style :param/:returns tags with prose and then repeats the object-store workflow across three sentences. It is usable but padded, with some redundancy about passing the object ID to other functions.

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?

For a two-param, no-output-schema, no-annotation tool, the description does cover the return shape (paginated activity events/preview) and the object-store handoff, which is the main gap. It is nonetheless thin on parameter meaning and on how the activity list relates to the deployment revision tools.

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 0%, so the description must compensate. It does name both params, and 'after: the cursor to fetch the next page' usefully explains the opaque anyOf/null cursor field, but 'deployment_id: ID of the deployment' is tautological and adds nothing over the schema title.

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?

States a specific verb and resource — listing activation and revision activity for a deployment — which is distinct from revision-listing siblings like list_deployment_revisions. It does not explicitly name or contrast with those siblings, so it stops short of a 5.

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?

There is no when-to-use guidance and no condition that selects this tool over list_deployment_revisions, get_deployment_revision, or get_deployment_stats. The reader must infer the use case from the purpose sentence alone.

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