get_recent_activity

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

No annotations are provided, and the description adds almost no behavioral disclosure. It does not state whether the tool is purely read-only, what the response looks like, whether there are rate limits or authentication requirements, or what 'categories' are referenced in the schema. The description is too thin to convey expected behavior beyond a simple read operation.

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, concise sentence with no filler or redundant content. It is front-loaded with the action and resource, making it easy to scan. Every word adds some value, even the 'debugging purposes' clause provides a usage hint.

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 tool with one optional parameter, no output schema, and no annotations, the description carries the burden of explaining what 'activity' means and what the tool returns. It fails to do so, leaving the agent guessing about the result format or the scope of activity. The description is too incomplete for reliable use.

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 fully documents the only parameter ('limit' with a description and default). The description adds no additional semantic information about the parameter. With 100% schema coverage, the baseline of 3 is appropriate, as the schema does the heavy lifting.

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 states a clear verb ('get') and a resource ('recent activity'), but 'activity' is vague and does not specify what kind of activity (e.g., user actions, system events). It does not distinguish itself from sibling tools like 'get_interaction_history' or 'get_artifact_reads', which likely also return recent activity. The debugging hint is the only differentiator, but the core resource remains ambiguous.

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 phrase 'for debugging purposes' implies a use case but is not specific. There is no explicit guidance on when to use this tool versus alternatives, no exclusions, and no clear scenarios. It provides minimal context but falls short of clear usage instructions.

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