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

The readOnlyHint annotation already declares the operation as safe, and the description adds contextual behavior about the active Space scoping and the ability to override with space_id. This is useful but does not go beyond what the annotation and schema already imply. No contradictions found.

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?

Two concise sentences that front-load the main purpose and scope, with no redundant information. Every sentence earns its place.

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 the tool's simplicity and the presence of a 100%-covered schema, the description sufficiently covers the operation. It mentions the return contents (status and totals) and pagination is implied via the cursor parameter. However, there is no output schema, so a bit more detail on the return shape could be helpful, but it is not critical for this type of list tool.

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 coverage is 100%, with each parameter described in the schema. The description adds no additional parameter semantics beyond what the schema provides, so the baseline of 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?

The description clearly specifies the verb ('List'), the resource ('recent syncs'), the scope ('for the active Space'), and the ordering ('most recent first'). It also mentions the included data ('status and totals'), which distinguishes it from siblings like get_sync_status (single status) and trigger_sync (initiating a sync).

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 provides clear usage context: it is scoped to the active Space, and it explicitly points to set_active_space to switch spaces or space_id to override. It does not explicitly mention alternatives or exclusion criteria, but the scoping guidance is practical and sufficient.

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