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

No annotations provided, so description must disclose behavioral traits. It states 'Get' implying read-only, but fails to clarify time range ('recent' is vague), permissions requirements, pagination, or output format. Minimal detail leaves many behavioral questions unanswered.

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?

Single sentence with 10 words, front-loading the action and key details. No unnecessary words. Maximally concise while conveying core purpose.

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?

Given a simple tool with one parameter, no output schema, and no annotations, the description is adequate for basic understanding but leaves gaps: 'recent' is undefined, no mention of result format or potential errors. Could be more informative without being verbose.

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 parameter (workspace_id) has a trivial schema description 'Workspace ID'. Description adds no extra meaning or usage guidance (e.g., where to find it, format constraints). With 100% schema coverage but minimal schema description, the description should add value but does not.

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 clearly states verb (Get), resource (recent activity in a workspace), and specifies types (file writes, comments, shares). Distinguishes from sibling tools like drive_comment (get specific comments), drive_share (share files), drive_write (write files).

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?

Implicitly indicates use for retrieving activity, but no explicit when-to-use or when-not-to-use. No guidance on alternatives among many sibling tools (e.g., drive_list lists files, drive_context provides workspace context). Adequate but lacks explicit differentiation.

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